AIM:To compare the three-dimensional choroidal vascularity index(CVI)and choroidal thickness between fellow eyes of acute primary angle-closure(F-APAC)and chronic primary angle-closure glaucoma(F-CPACG)and the eyes of normal controls.METHODS:This study included 37 patients with unilateral APAC,37 with asymmetric CPACG without prior treatment,and 36 healthy participants.Using swept-source optical coherence tomography(SS-OCT),the macular and peripapillary choroidal thickness and three-dimensional CVI were measured and compared globally and sectorally.Pearson’s correlation analysis and multivariate regression models were used to evaluate choroidal thickness or CVI with related factors.RESULTS:The mean subfoveal CVIs were 0.35±0.10,0.33±0.09,and 0.29±0.04,and the mean subfoveal choroidal thickness were 315.62±52.92,306.22±59.29,and 262.69±45.55μm in the F-APAC,F-CPACG,and normal groups,respectively.All macular sectors showed significantly higher CVIs and choroidal thickness in the F-APAC and F-CPACG eyes than in the normal eyes(P<0.05),while there were no significant differences between the F-APAC and F-CPACG eyes.In the peripapillary region,the mean overall CVIs were 0.21±0.08,0.20±0.08,and 0.19±0.05,and the mean overall choroidal thickness were 180.45±54.18,174.82±50.67,and 176.18±37.94μm in the F-APAC,F-CPACG,and normal groups,respectively.There were no significant differences between any of the two groups in all peripapillary sectors.Younger age,shorter axial length,and the F-APAC or F-CPACG diagnosis were significantly associated with higher subfoveal CVI and thicker subfoveal choroidal thickness(P<0.05).CONCLUSION:The fellow eyes of unilateral APAC or asymmetric CPACG have higher macular CVI and choroidal thickness than those of the normal controls.Neither CVI nor choroidal thickness can distinguish between eyes predisposed to APAC or CPACG.A thicker choroid with a higher vascular volume may play a role in the pathogenesis of primary angle-closure glaucoma. 展开更多

AIM:To compare the macular ganglion cell-inner plexiform layer(GCIPL)thickness,retinal nerve fiber layer(RNFL)thickness,optic nerve head(ONH)parameters,and retinal vessel density(VD)measured by spectral-domain optical coherence tomography(SD-OCT)and analyze the correlations between them in the early,moderate,severe primary angle-closure glaucoma(PACG)and normal eyes.METHODS:Totally 70 PACG eyes and 20 normal eyes were recruited for this retrospective analysis.PACG eyes were further separated into early,moderate,or severe PACG eyes using the Enhanced Glaucoma Staging System(GSS2).The GCIPL thickness,RNFL thickness,ONH parameters,and retinal VD were measured by SD-OCT,differences among the groups and correlations within the same group were calculated.RESULTS:The inferior and superotemporal sectors of the GCIPL thickness,rim area of ONH,average and inferior sector of the retinal VD were significantly reduced(all P<0.05)in the early PACG eyes compared to the normal and the optic disc area,cup to disc ratio(C/D),and cup volume were significantly higher(all P<0.05);but the RNFL was not significant changes in early and moderate PACG.In severe group,the GCIPL and RNFL thickness were obvious thinning with retinal VD were decreasing as well as C/D and cup volume increasing than other three groups(all P<0.01).In the early PACG subgroup,there were significant positive correlations between retinal VD and GCIPL thickness(except superonasal and inferonasal sectors,r=0.573 to 0.641,all P<0.05),superior sectors of RNFL thickness(r=0.055,P=0.049).More obvious significant positive correlations were existed in moderate PACG eyes between retinal VD and superior sectors of RNFL thickness(r=0.650,P=0.022),and temporal sectors of RNFL thickness(r=0.740,P=0.006).In the severe PACG eyes,neither GCIPL nor RNFL thickness was associated with retinal VD.CONCLUSION:The ONH damage and retinal VD loss appears earlier than RNFL thickness loss in PACG eyes.As the PACG disease progressed from the early to the moderate stage,the correlations between the retinal VD and RNFL thickness increases. 展开更多

AIM: To evaluate the efficacy of combined treatment of phacoemulsification(PE) and micro-incisional single-port transconjunctival limited pars plana vitrectomy(PPV) in acute angle-closure glaucoma(AACG).METHODS: A retrospective study included 26 patients who underwent PE diagnosed with AACG. Among them, 16 patients(16 eyes) underwent PE alone, 10 patients(10 eyes) underwent combined limited vitrectomy and PE. Then we compared intraocular pressure(IOP), anterior chamber angle, anterior chamber depth, central corneal thickness and corneal endothelial cell count before and after surgery, and effective PE time during cataract surgery.RESULTS: Effective PE time was shorter in the combined surgery group than in the single surgery group(P=0.040). There was no statistically significant difference in IOP and best-corrected visual acuity between the two groups postoperatively. At 6 mo postoperatively, there was no difference in the anterior chamber angle, anterior chamber depth, and central corneal thickness between two groups, but corneal endothelial cell count was higher in the combined surgery group than in the single surgery group(P=0.046). No complication such as vitreoretinal disease, endophthalmitis, bullous keratopathy was noted.CONCLUSION: Combined micro-incisional single-port transconjunctival limited PPV and PE are more effective and safer than PE alone because of less operation time and fewer complications for management of AACG. 展开更多

AIM:To evaluate changes of proinflammatory cytokines in aqueous humor of patients with acute primary angleclosure(APAC) and age-related cataracts. METHODS:Twenty eyes of 20 APAC patients and 15 eyes of 15 age-related cataract patients were included in this cross-sectional study. Aqueous humor samples were collected prospectively. The levels of 20 proinflammatory cytokines were evaluated in the aqueous humor of the APAC and cataract patients using the multiplex bead immunoassay technique. Clinical data were collected for correlation analysis.RESULTS:Seven of the 20 proinflammatory cytokines included in the magnetic bead panel were detectable in both APAC eyes and cataract eyes:interleukin(IL)-10, IL-12, IL-15, IL-21, IL-6, chemokine(C-C motif) ligand 20, and tumor necrosis factor alpha(TNF-α). IL-27 was only detectable in APAC eyes. Compared with the cataract eyes, the APAC eyes had significantly elevated concentrations of IL-12(P=0.036), IL-15(P=0.001), IL-6(P=0.012), and IL-27(only detectable in APAC eyes). Age was positively correlated with IL-12(P=0.022) and IL-6(P=0.037), and time elapsed between APAC onset and aqueous humor samples collection was positively correlated with IL-15(P=0.037), IL-27(P=0.040), and TNF-α(P=0.042).CONCLUSION:Several proinflammatory cytokines including IL-12,IL-15, IL-6 and IL-27, were elevated in the APAC eyes and may be implicated in its pathologic mechanism. 展开更多

AIM:To evaluate the morphological changes in anterior segment in Chinese patients with uveal effusion(UE)after the attack of acute primary angle-closure(APAC)using ultrasound biomicroscopy(UBM),and to assess the clinical course and prognosis of the disease.METHODS:In a retrospective case series,26 eyes in 26 consecutive patients diagnosed with UE after the treatment of intraocular pressure(IOP)-lowering medication for the attack of APAC were enrolled. The unaffected fellow eyes served as controls. The morphological changes were observed by ultrasonography,slit lamp microscopy and gonioscopy. UBM was used to assess the degree and extent of effusion based on the analysis of parameters associated with UE.RESULTS:The mean IOP was 9.2(SD 2.1)mm Hg at the diagnosis of UE after IOP-lowering medication,while 14.1(SD,2.6)mm Hg in the fellow eyes(P=0.000). The anterior chamber depth(ACD)(P=0.000),angle opening distance at 500 μm(AOD500)(P〈0.01)and anterior chamber angle(ACA)(P〈0.05)were decreased significantly,while ciliary body thickness(CBT)(P〈0.05)increased significantly in UE eyes. UE grade analysis showed 7 eyes in grade 1,9 eyes in grade 2,and 10 eyes in grade 3. Quadrant scores were performed of 4 eyes in 1 quadrant,3 eyes in 3 quadrants,and 19 eyes in 4 quadrants. There was the positive correlation between grade and quadrant score(R=0.644,P=0.000). The effusion on all eyes were recovered after medication,which mean IOP was 13.9(SD,2.8)mm Hg.CONCLUSION:UE is a frequent complication in Chinese patients after the attack of APAC,partially associated with hypotony. The severity of UE is correlation with height of effusion,extent of detachment,and shallower ACD. 展开更多

Background:To measure the anterior and posterior segment structural features of acute primary angle-closure(APAC)eyes.Methods:A total of 36 subjects with unilateral APAC were recruited in this study.The ocular biometric characteristics were measured by anterior segment optical coherence tomography(AS-OCT)and swept source optical coherence tomography(SS-OCT),respectively at baseline,2 weeks,and 1 month after surgical intervention.Results:At baseline,when compared with the fellow eyes,APAC-affected eyes showed significantly greater corneal thickness(P=0.004),shallower anterior chamber depth(ACD)(P<0.001),smaller anterior chamber area(ACA)(P=0.013),angle opening distance at 750μm from the scleral spur(AOD750)(P=0.002),trabecular-iris space area at 750μm from the scleral spur(TISA750)(P=0.033),angle recess area(ARA)(P=0.014),and iris area(IARE)(P=0.003),less iris curvature(ICURVE)(P=0.003),and larger lens vault(LV)(P=0.030).After intervention,the corneal thickness was significantly decreased at 1 month(P<0.001),while ACD,ACA,and AOD750 were significantly increased at 2 weeks and 1 month(all P<0.017).Changes in ACD were correlated with decreasing LV(P<0.05).The posterior segment parameters did not change over the 4-week period.Conclusions:When compared with the fellow eyes,APAC-affected eyes had greater corneal thickness,shallower anterior chamber,narrower angle,less ICURVE,and larger LV.After intervention,the corneal thickness was decreased,while the shallower anterior chamber was relieved to some extent. 展开更多

AIM: To evaluate the value of quantitative diffusion tensor imaging (DTI) in assessing the axonal and myelin damage of the optic nerves and optic radiations in patients with chronic primary angle -closure glaucoma (PACG) by using high -field magnetic resonance (MR) imaging (3T). METHODS: Twenty patients with bilateral chronic PACG and twenty age - and sex matched disease -free control subjects were enrolled. Conventional MRI and DTI were performed on all subjects using 3T MR scanner. Mean diffusivity (MD), fractional anisotropy (FA), axial diffusivities (AD) and radial diffusivities (RD) of each optic nerve and each optic radiation were measured by using post -processing software of DTI studio 2.3, and then compared between left eyes and right eyes and between patients group and control group. The pairedsample t- test were used. RESULTS: There was no abnormality in the shape and signal intensity of the optic nerves and optic radiations in patients group and control group on the conventional MRI. No significant differences were observed in the FA, MD, AD and RD between the right and left optic nerves and optic radiations within patients group and control group (P>0.05). The optic nerves and optic radiations of patients with chronic PACG, as compared with control subjects, had significantly higher MD, AD, RD and significantly lower FA (P<0.05). CONCLUSION: The diffusivity of optic nerves and optic radiations in chronic PACG group showed abnormal and diffusivity parameters could be used markers of axonal and myelin injury in glaucoma. 展开更多

AIM: To assess the changes in the anterior chamber parameters using Pentacam following four different lines of treatment of primary angle-closure glaucoma(PACG).METHODS: A retrospective comparative study included 126 patients(126 eye) presented within 24-48 h after acute angle-closure glaucoma(AACG). Patients were divided into 2 groups: group A(68 eyes) with controlled intraocular pressure(IOP) ≤21 mm Hg, which included subgroup A1(34 eyes) with clear lens underwent Nd:YAG laser peripheral iridotomy(LPI) and subgroup A2(34 eyes) with cataract underwent standard phacoemulsification;and group B(58 eyes) with uncontrolled IOP, which included subgroup B1(30 eyes) with clear lens underwent trabeculectomy and subgroup B2(28 eyes) with cataract underwent combined phacoemulsification and trabeculectomy. Patients were fol owed up for at least 3 mo. Primary outcomes were Pentacam anterior segment measurements [anterior chamber angle(ACA) and depth(ACD)]. Secondary outcomes were changes in IOP, visual acuity(VA) and recorded complications. RESULTS: At the 3^(rd)month, there was significant increase in the ACA values in all studied groups compared to preoperative values(P<0.001). The highest percent of increase in ACA was recorded in phacotrabeculectomy group B2(128.40%). There was significant increase in ACD values at 3^(rd)month compared with baseline values(P<0.001) for groups A1, A2, and B2;without change in B1 trabeculectomy group. The maximum deepening of ACD was noticed in group B2 with 94.27% increase. Significantdecrease in postoperative IOP in groups A2, B1 and B2(P<0.001, P=0.014, and P<0.001 respectively). In group A1 there was significant increase in 3^(rd)month postoperative IOP from baseline values(P<0.001). The maximum decrease in IOP was noticed in group B2 with 59.54% decrease. VA improvement in 3^(rd)month postoperative was recorded in all studied groups, maximum VA improvement was observed in group B2 up to 0.2 log MAR.CONCLUSION: Pentacam can be a helpful tool in studying and comparing the effect of the different lines of management of PACG on the anterior chamber measures. Phacotrabeculectomy was proved to be an effective line for managing PACG with resultant significant increase in the anterior chamber parameters, IOP reduction as well as maximum VA improvement. LPI has only temporary effect on IOP with significant changes in ACA and ACD. Phacoemuslification alone can be an option in treating PACG. Trabeculectomy resulted in temporary increase in the anterior chamber parameter which subsequently returned to baseline values. 展开更多

AIM:To examine the association between the single nucleotide polymorphisms (SNPs)of matrix metalloprotease-9 (MMP-9) gene and primary angleclosure glaucoma(PACG)in a Chinese Han population.METHODS:DNA samples were extracted from peripheral-blood mononuclear cells of 214 PACG patients and 224 healthy controls.Genotyping of rs3918249,rs3918254,rs17577 and rs3787268 in MMP-9was performed using polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP)analysis and the direct sequencing technique.The association between these genetic polymorphisms and risk of PACG was estimated by χ2 test.RESULTS:The distributions of rs3918249,rs3918254,rs17577 and rs3787268 genotypes among cases and healthy controls were compatible with that from HardyWeinberg equilibrium(HWE,P】0.05).The increased frequency of CC and CT genotypes of rs3918254 were observed in PACG patients compared to healthy controls[P=0.006,P corrected(Pcorr)=0.048].The haplotype analysis showed that the CCGG haplotype was nominal associated with PACG(P=0.015),however,the significant was lost when the Bonferroni correction was used(Pcorr=0.105).CONCLUSION:Our results revealed that rs3918254 in MMP-9 may be a susceptible locus to PACG in China,people with the CC and CT genotypes of rs3918254 are more susceptible to PACG.The susceptibility to PACG inChinese Han patients may be not influenced by SNPs rs3918249,rs3787268 and rs17577 in MMP-9. 展开更多

AIM: To compare the efficacy and safety of phacoemulsification(Phaco) against combined phacotrabeculectomy(Phacotrabe) in primary angle-closure glaucoma(PACG) with coexisting cataract.·METHODS: By searching electronically the Pub Med,EMBASE, Scientific Citation Index and Cochrane Library published up from inception to January 2014, all randomized controlled trials that matched the predefined criteria were included. The quality of included trials was evaluated according to the guidelines developed by the cochrane collaboration. And the outcomes estimating efficacy and safety of two different surgical treatments were measured and synthesised by Rev Man 5.0.· RESULTS: Five randomized controlled trials were selected and included in Meta-analysis with a total of468 patients(468 eyes) with both PACG and cataract. We found that Phacotrabe had a greater intraocular pressure(IOP) lowing effect [preoperative IOP: weighted mean difference(WMD)=0.58, 95% confidence intervals(95% CI,-0.53 to 1.69), P =0.31; postoperative IOP: WMD =1.37,95% CI(0.45 to 2.28), P =0.003], a lower number of antiglaucoma medications [risk ratio(RR)=0.05, 95% CI(0.02 to 0.18), P 〈0.00001] needed postoperatively and less serious damage of optic nerve [RR =0.48, 95% CI(0.21 to 1.07), P =0.07], but a higher risk of complications[odds ratio(OR)=0.04, 95% CI(0.01 to 0.16), P 〈0.00001]compared with Phaco. The rest studies indicated that there had no significantly difference between the two surgical methods for postoperative best-corrected visual acuity(BCVA) [WMD =-0.05, 95% CI(-0.14 to 0.05), P =0.32] and loss of visual field [RR=1.06, 95% CI(0.61 to1.83), P =0.83].·CONCLUSION: Phaco alone compared with Phacotrabe had a better effect in IOP reduction, whereas the securitydecline. Considering the number of sample size, our results remains to be further studied. 展开更多

AIM:To investigate the association of peripheral anterior synechiae(PAS)with intraocular pressure(IOP)and glaucomatous optic neuropathy(GON)in primary angle closure(PAC)and primary angle-closure glaucoma(PACG).METHODS:Totally 355 eyes(238 PAC and 117 PACG)of 181 patients were included in this retrospective analysis of baseline data from a randomized clinical trial.All patients had undergone a comprehensive ophthalmic examination.The extent of PAS in clock hours as determined on gonioscopy was documented.The independent effect of the extent of PAS on IOP and the prevalence of GON were determined using multivariable generalized estimating equation(GEE)models.RESULTS:The frequency of GON increased with the extent of PAS and a higher IOP.PAS were more extensive(8 vs 1 clock hour,P<0.001)and IOP higher(28.01 vs 18.00 mm Hg,P<0.001)in PACG compared to PAC.The prevalence of GON among the PAS quartiles were 10.2%(PAS<0.5 clock hours),16.9%(PAS≥0.5 and PAS<3 clock hours),29.6%(PAS≥3 and PAS<7 clock hours),and 74.4%(PAS≥7 clock hours),respectively.After adjusting for IOP,age,gender,spherical equivalent,average Shaffer score and number of medications,the odds ratio(OR)for GON was 4.4(95%CI:1.5-13.0;P=0.007)with PAS≥3 clock hours and 13.8(95%CI:4.3-43.6;P<0.001)with PAS≥7 clock hours as compared to eyes with PAS<0.5 clock hours.The frequency of GON increased linearly with the extent of PAS.Extent of PAS was also associated with higher IOP.Eyes with both PAS≥6 clock hours and IOP≥21 mm Hg had the highest risk of GON compared to eyes with both PAS<6 clock hours and IOP<21 mm Hg(OR=18.0,95%CI:7.5-43.4;P<0.001).CONCLUSION:The extent of PAS in PAC and PACG is an important predictor of higher IOP and is linearly associated with GON independent of IOP,suggesting other factors related to PAS formation may be involved in the development of GON in PACG. 展开更多

AIM: To determine the levels of aquaporin-1(AQP-1) in the lens epithelial cells(LECs) of primary glaucoma and to clarify its correlation with lens thickness.METHODS: This study comprised 64 eyes of 64 patients with primary glaucoma, who were divided into 3 groups: 25 eyes of 25 patients with acute primary angle-closure glaucoma(APACG), 19 eyes of 19 patients with chronic primary angle-closure glaucoma(CPACG) and 20 eyes of 20 patients with primary open angle glaucoma(POAG). This study also included 12 eyes of 12 patients with senile cataract as controls. The levels of AQP-1 in LECs were examined by real-time quantitative polymerase chain reaction(RT-q PCR) and immunohistochemistry. The lens thickness was measured by A-scan ultrasonography. RESULTS: The AQP-1 m RNA levels of LECs were 0.84±0.27, 0.69±0.34, 0.44±0.19 and 0.51±0.21 in APACG, CPACG, POAG and senile cataract group, respectively. The levels of AQP-1m RNA were significantly higher in PACG groups compared with those in senile cataract and POAG group(all P〈0.05). The immunohistochemistry showed the AQP-1 expression were strong-positive in PACG groups, but weak-positive in senile cataract and POAG group. A positive correlation was found between AQP-1 m RNA levels and the lens thickness(r=0.645, P〈0.001). CONCLUSION: These findings show that the higher expression of AQP-1 in LECs may contribute to increased lens thickness, which might be associated with the occurrence and development of PACG. 展开更多

Methods:38 eyes of 20 patients with primary angle-closure glaucoma (PACG) and 35 eyes of 22 normal individuals without ocular abnormalities were examined. The anatomical parameters of the lens and other structures of the anterior segment were calculated using B ultrasound, computer image processing and ultrasound biomicroscopy (UBM). The parameters were compared between the patients and normal subjects. Correlation analysis was used to determine the relationship between the radii of curvature of the anterior lens surface (RCALS) and the other parameters of the anterior segment. Results:Compared with the normal eyes, the eyes of PACG had thicker lens, steeper curvature of anterior lens surface, decreased depth of the anterior chamber, narrower chamber angle, and more anterior position of the ciliary bodies and lens. All these differences were significant(P 〈 0.05 or P 〈 0.01). In the PACG group, the RCALS had significantly negative correlation with the central and peripheral lens thickness (P 〈 0.01 and P 〈 0.05 respectively), and had positive correlation with relative lens position, anterior chamber depth(ACD), angle-open distance at 500 um(AOD500), trabecular iris angle (TIA) and trabecular ciliary processes distance(TCPD, P 〈 0.05 or P 〈 0.01 ). Conclusion:The occurrence of PACG is relevant to the abnormal anatomical structures of the anterior segment. Among all factors, the lens parameters play an important role in the pathogenesis. Increased lens thickness, relative more anterior position of lens, especially steepened curvature of anterior lens surface are predisposing factors of the pathologic phenomenon in PACG including pupillary blockage, shallow anterior chamber, secondary closure of chamber angle and elevation of intraocular pressure. 展开更多

Purpose: To identify the anterior segment parameters associated to acute primary angle closure. Patients and Methods: Case-control study in 58 primary angle closure suspect eyes (PACS, control group) and in 19 acute primary angle closure fellow eyes, case group. All subjects underwent SL OCT imaging in a dark room. Results: The SS, ACD and ACV measures were significantly smaller in case group than in control group (p = 0.011;p < 0.001;p = 0.007 respectively);while the IT was significantly greater (at 500 and 750 μm) (p = 0.038 and p = 0.050). The difference between quadrants were statistically significant only for control group (p = 0.001;p = 0.003;p = 0.009;p = 0.018;p = 0.002 and p 500, AOD500, AOD750, TISA500, and TISA750 respectively. Conclusion: Acute primary angle closure is associated to the smaller anterior segment dimensions and the thicker iris compared to PACS. 展开更多

METHODS: Retrospective cohort. Data was collected from charts of all PACD patients treated from April 2013 to December 2015. Analysis was done on 137 patient charts with complete biometric data. Patient demographics, PACD type, refractive status (spherical equivalent), ACD and AL were studied. RESULTS: The median age of 137 subjects [53 with primary angle-closure suspects (PACS), 27 with primary angle- closure (PAC) and 57 with primary angle-closure glaucoma (PACG)] was 68y (range 21-88y). The majority was Chinese (n=68; 49.6%) and most of them were women (n=75; 54.7%). The distribution of myopia (n=51; 37.2%) and hyperopia (n=49; 35.8%) was similar. The ACD was shallower in myopes compared to hyperopes (P=-0.02) and emmetropia (P=-0.049) but the AL was not significantly different between groups. There were no patients blind from PACG. CONCLUSION: Both myopia and hyperopia can occur in PACD. Despite a shallower ACD in angle closure myopes, the AL was not different between groups. 展开更多

Background: Goniosynechialysis is a surgical procedure that has been shown to slow the progression of glaucoma in oriental eyes with chronic angle closure glaucoma. This procedure was successful in 80% of cases, and the peripheral anterior syenchiae did not exist until one year later. Nonetheless, there is little evidence of its efficacy in our context. Our study aims to investigate the efficacy of goniosynechialysis during phacoemulsification in patients with primary angle closure disease and concomitant cataract. Methods: This was an observational, prospective study. The intra-ocular pressure, need for anti-glaucoma drugs, visual acuity, the extent of synechiae, anterior chamber depth, surgical success rate, and other indicators were monitored for at least three months following surgery. Results: This study included 114 patients (118 eyes), 61 with chronic angle closure glaucoma (51.69%), 33 with primary angle closure (27.97%), and 24 with acute attack angle closure (20.34%), who were surgically treated with phacoemulsification and goniosynechialysis (Phaco-GSL). The mean intra-ocular pressure had significantly decreased three months after surgery (pre- vs post-op: 22.04 ± 10.86 vs 15.41 ± 6.06 mmHg, p-value p-value p-value p-value p-value Conclusion: Regardless of the type of glaucoma, combined phacoemulsification-goniosynechialysis is effective in lowering pressure, restoring vision, reducing the need for anti-glaucoma drugs, and preventing the synechial recurrence. Success was higher in eyes with less extensive synechiae. Phaco-GSL is safe and effective in the treatment of primary angle closure diseases with co-existing cataract. 展开更多

AIM To evaluate the efficacy and safety of trabeculectomy, phacotrabeculectomy plus intraocular lens implantation (phacotrab+IOL group) and phacoemulsification with IOL (phaco+IOL) in primary angle-closure glaucoma(PACG). METHODS: It was a systematic review and meta-analysis, randomized controlled trials(RCT) and clinical controlled trials (CCT) were collected through electronic searches of the Cochrane Library, PubMed, EMbase, Wanfang Database online, Chinese journal Full-text Database, Chinese Scientific Journals Full-text Database (from the date of building the database to October 2010) We also checked the bibliographies of retrieved articles. M the related data that matched our standards were abstracted. The quality of included trials was evaluated according to the Dutch Cochrane Centre. Rev Man 5.0 software was used for Meta-analysis. RESULTS: A total of 5 RCT and 11 CCT involving 1495 eyes were included. The results of meta-analysis showed that phacotrab+IOL group was superior than trabeculectomy(trab group) (MD -3.93,95% CI [-7.31, -0.54]) which was also superior than phaco+IOL group(MD 0.52,95%CI [0.10, 0.95]) in decreasing Intraocular Pressure(IOP). Phacotrab group(MD -1.45,95%CI [-1.68, -1.22])and phaco group (MD-1.12,95% CI [-1.87, -0.37])are both deeper than trab group in the anterior chamber depth. In increasing the coefficient of outflow facility of aqueous humor (C values) there was no statistical difference in the three groups. And there was no statistical difference between phacotrab groups and phaco groups in visual acuity but phacotrab group was superior than phaco group (MD 1.07, 95% CI [0.73, 1.40])in the use of IOP-lowering drugs. There was no statistical difference among three groups. CONCLUSION: Current evidence suggests that phacotrab+IOL group was superior than tab group which was also superior than phaco+IOL group in decreasing IOP. Phacotrab group and phaco group are both deeper than trab group in the anterior chamber depth. Phacotrab group was superior than phaco group in the use of IOP-lowering drugs. 展开更多

Intraocular pressure(IOP)modifications in patients with acute central/hemicentral retinal vein occlusions(RVOs)consist in IOP reductions and increases.The IOP reduction is due to a transitional hyposecretory phase of the aqueous humor,that increases gradually until 3 mo after the venous occlusion onset,and then finally disappears after month 4 th.The IOP increases lead to the ocular hypertension and glaucoma.The possible pathogenetic correlations between ocular hypertension/glaucoma and acute central/hemicentral RVOs have been classified into three groups:1)the venous occlusion precedes the ocular hypertension/glaucoma causing neovascular glaucoma and secondary angle-closure glaucoma without rubeosis;2)the ocular hypertension and the glaucoma precede the venous occlusion and favor its appearance(ocular hypertension,primary angle-closure,primary angle-closure glaucoma,and open angle glaucomas);and 3)the venous occlusion and the ocular hypertension/glaucoma are mostly age dependent appearances due to common vascular and collagen alterations,lacking a causal connection between the 2 conditions. 展开更多
