Phacoemulsification versus combined phacotrabeculectomy in the treatment of primary angle-closure glaucoma with cataract: a Meta-analysis

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.

A Meta-Analysis: Safety and Efficacy of Phacoemulsification with Goniosynechialysis versus Trabeculectomy for Acute Angle Closure Glaucoma in China

Aim: The aim is to evaluate the safety and efficacy of phacoemulsification with goniosynechialysis versus trabeculectomy in the treatment of acute angle closure glaucoma (AACG) systematically. Methods: From January 1, 2000 to August 31, 2022, we searched PubMed, Science Citation Index Database, China National Knowledge Infrastructure, and Wanfang Database for pertinent material about the treatment of AACG with various operations. The imported literature was carefully vetted using the inclusion and exclusion criteria, assessed for quality, and the raw data were retrieved and integrated into EndNoteX9. For the meta-analysis, STATA 16.0 and RevMan 5.3 were used as the tools. Results: The meta-analysis includes 20 clinical investigations in all, involving 1463 eyes. The quality of the literature was rated as excellent and the data homogeneity among the studies was excellent based on the various study types that were included in the literature. According to a meta-analysis, phacoemulsification with goniosynechialysis is superior to trabeculectomy for treating acute angle-closure glaucoma because it results in improved postoperative visual acuity, lower intraocular pressure, a broader anterior chamber depth, and fewer complications. Conclusion: If conditions allow, phacoemulsification in conjunction with goniosynechialysis performs better than trabeculectomy in terms of visual acuity, intraocular pressure, anterior chamber depth, and comorbidities.

Phacoemulsification with or without goniosynechialysis for angle-closure glaucoma: a global Meta-analysis based on randomized controlled trials

AIM: To compare the benefits and potential harms of routine phacoemulsification(phaco) alone and combined surgery with goniosynechialysis(GSL) for angle-closure glaucoma(ACG) and coexisting lens opacity, as shown in different randomized controlled trials(RCTs).METHODS: A systematic review was conducted searching several databases including PubMed, Cochrane Library, EMBASE, ClinicalTrials.gov from the inception to September 2018 for RCTs with data published on the effects and safety of phaco and intraocular lens implantation combined with GSL or routine cataract surgery alone. Several studies were recruited which reported data at baselines and postoperative follow-up, including the mean values of postoperative intraocular pressure(IOP) and mean numbers of antiglaucoma medications using postoperatively. The numbers of complications happening were also included. Fixedeffect and random-effect models were applied, and the quality of evidence was evaluated.RESULTS: Analysis of the seven included RCTs, with a total number of 321 participants(358 eyes) diagnosed with ACG and cataract, received a solo procedure(phaco group) or a combined surgery(phaco-GSL group) randomly, and follow-up periods ranging from 2 to 12 mo postoperatively. The involved studies showed that the mean value of IOP between the two groups at 3(four studies, one study follow-up at 2 mo postoperative was included), 6, 12 mo postoperative were not significantly different. Only two studies reported the change in IOP value at 12 mo compared with baseline but showed nosignificant differences between the two interventions. Although three studies did not have the significant difference in the number of medications using to reduce IOP at 3 mo postoperatively, two studies reported that the participants using fewer anti-glaucoma medications at 12 mo postoperative in the phaco group than in the phacoGSL surgery group.CONCLUSION: The analysis provides a low to moderatequality evidence that phaco-GSL surgery lead to an equivalent IOP-lowering effect. The phaco-GSL surgery may not help patients to reduce the consumption of antiglaucoma eyedrops in the long period. The results of this analysis suggested that additional GSL may not be necessary for primary angle closure glaucoma(PACG) patients. Further studies, especially RCTs with more participants and longer follow-up time were needed to provide more sufficient data.

Combined treatment of phacoemulsification and single-port limited pars plana vitrectomy in acute angle-closure glaucoma

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.

Bilateral acute angle closure glaucoma precipitated by over the counter oral decongestant

Dear Sir,We hereby report a case of bilateral acute angle closure glaucoma secondary to a systemic decongestant containing pseudoephedrine freely available over the counter.Acute angle closure glaucoma is an ocular emergency.Delayed recognition and treatment inevitably leads to permanent visual impairment.Acute angle closure occurs as a result of obstruction to aqueous drainage by blockage of the trabecular meshwork by the iris.Typical presenting symptoms include acute onset of ocular pain,headache and blurred vision.On clinical examination,it is characterized by a markedly raised IOP of above 21 mm Hg together with

Safety and Efficacy of Combined Trabeculectomy for Primary Angle Closure Glaucoma with Persistent Ocular Hypertension

Purpose:To investigate the safety and efficacy of combined trabeculectomy for primary acute angle closure glaucoma with persistent ocular hypertension.Methods:A total of 36 patients.(40 eyes).with primary acute angle closure glaucoma,who were treated with combined trabeculectomy in the Ophthalmology Unit of our hospital,were selected.Before the procedure,patients were assigned to ocular hypertension group(≥ 40 mm Hg) or control group(< 40 mm Hg) based on intraocular pressure.These two groups were followed up for one year,and compared for post-operative visual acuity,intraocular pressure,filtering bleb,anterior chamber depth,and the occurrence of complications.Results:At 1 week,6 months,and 12 months after the procedure,intraocular pressure was controlled in both the ocular hypertension group and the control group,without significant differences between the two groups(P>0.05).At 1 week,6 months,and 12 months after the procedure,all of the patients,in both groups,had improved in terms of visual acuity,with a significant difference before and after the procedure for the ocular hypertension group(P<0.05).After follow-up at 12 months,the two groups presented no statistically significant differences in anterior chamber depth,filtering bleb survival,or the incidence of post-operative complications(P>0.05 for all).Conclusion:It is feasible,safe,and effective to perform combined trabeculectomy on patients with primary acute angle closure glaucoma complicated by persistent ocular hypertension.

Clear lens extraction in angle-closure glaucoma patients

AIM: To describe the results of 5 consecutive cases of clear lens extraction in angle closure patients for the treatment of elevated intraocular pressure (IOP). ·METHODS: Retrospective observational case series. All angle closure patients were on two or more topical glaucoma medications and had prior laser iridotomy. Eyes underwent clear lens extraction by phacoemu - lsification with intraocular lens implantation. ·RESULTS: All five patients in this case series carried the diagnosis of angle -closure glaucoma and had uncontrolled IOP prior to surgery despite topical medications. After clear lens extraction three of the cases had good IOP control (IOP 【22mmHg) without the need for topical medications. In one case the IOP was better controlled after surgery, however, topical medications were required. The desired IOP was not met in one case despite restarting maximum topical therapy. ·CONCLUSION: This case series suggests that there may be a role for therapeutic clear lens extraction in select cases of angle-closure glaucoma.

Role of Phacoemulsification in Angle Closure Glaucoma

Cataract or clear lens extraction has been suggested as a treatment option for different spectrums of primary angle closure diseases.It might reduce the risk of progression of angle closure and/or glaucoma by helping to open the angle and control the intraocular pressure (IOP).Conventionally,medically uncontrolled primary angle closure glaucoma was treated with trabeculectomy or phacotrabeculectomy and acute primary angle closure was treated with laser peripheral iridotomy. However,recent randomized controlled trials have demonstrated greater promise of phacoemulsification cataract surgery alone for control of the IOP. In this report we review the current literature to evaluate the impact of cataract surgery upon preventing and controlling primary angle closure diseases.

Angle parameter changes of phacoemulsification and combined phacotrabeculectomy for acute primary angle closure

·AIM: To evaluate the difference in angle parameters and clinical outcome following phacoemulsification and combined phacotrabeculectomy in patients with acute primary angle closure(APAC) using ultrasound biomicroscopy(UBM).·METHODS: Patients(n =23, 31 eyes) were randomized to receive phacoemulsification or combined phacotrabeculectomy(n =24, 31 eyes). Best-corrected visual acuity(BCVA), intraocular pressure(IOP), the main complications following surgery, and indentation gonioscopy and angle parameters measured using UBM were documented preoperatively and postoperatively.· RESULTS: The improvement in BCVA in the phacoemulsification group was significantly greater than in the combined group(P 【0.05). IOP in the phacoemulsification group was slightly higher than in the combined group following 1wk of follow-up(P 【0.05),whereas there was no significant difference between the two groups at the latter follow-up(P 】0.05).Phacoemulsification alone resulted in a slight increase in the trabecular ciliary processes distance compared with the combined surgery(P 【0.05), whereas the other angle parameters showed no significant difference between the groups. Complications in combined group were greater than phacoemulsification only group.·CONCLUSION: Both surgeries effectively opened the drainage angle and deepened the anterior chamber, and IOP was well controlled postoperatively. However,phacoemulsification showed better efficacy in improving visual function and showed reduced complications following surgery.

Efficacy of laser peripheral iridoplasty and iridotomy on medically refractory patients with acute primary angle closure： a three year outcome

Background Argon laser peripheral iridoplasty （ALPI） is proved to be effective in lowering intraocular pressure （lOP） of patients with mild acute primary angle closure （APAC）. It is unclear whether this laser treatment is equally efficient in managing patients with severe APAC. This study aimed peripheral iridotomy （LPI） on patients with refractory APAC, therapy. to evaluate the IOP-lowering efficacy of ALPI and laser who have previously responded poorly to intensive medical Methods Thirty-six patients （8 men and 28 women） were identified as medically refractory APAC, who still had ocular pain, red eye, hazy cornea, closed anterior chamber （AC） angle, and lOP of not less than 21 mmHg after two days or more of anti-glaucoma medication. All enrolled patients underwent ophthalmologic examinations including measurement of visual acuity （VA）, best corrected VA （BCVA）, lOP, biomicroscopy, and gonioscopy followed by ALPI immediately in the APAC eye and LPI in both eyes. Results All patients were affected unilaterally, with average age of （54.6±11.7） （range, 37.0-75.0） years old. The mean lOP value of the affected eyes dropped from （31.6±7.7） （range, 21.0-39.0） mmHg at enrollment to （18.4±8.7） （range, 10.0-27.0） mmHg 2 hours after ALPI. At follow-up day 7, the mean lOP value maintained at （14.8±4.2） （range, 9.0-21.0） mmHg, which was significantly different （P=0.000） compared with baseline. The average decrease of lOP in the APAC eyes was （16.8±7.4） （range, 12.0-21.0） mmHg. At follow-up three years later, the mean lOP of the APAC eyes stabilized at （16.3±3.2） （range, 9.0-20.0） mmHg with at least 180° of AC angle opened. Conclusion ALPI and LPI lower the lOP of medically refractory cases of APAC though they have responded poorly to anti-glaucoma medication.

Comparison of combined phacotrabeculectomy with trabeculectomy only in the treatment of primary angle-closure glaucoma

Background Trabeculectomy has become a mainstream treatment in intraocular pressure （lOP） reduction for primary angle-closure glaucoma （PACG）; combined trabeculectomy and cataract surgery was reported to reduce lOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract. Methods This is a comparative case series study. Thirty-one patients （31 eyes） with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone, lOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final lOP less than 21 mmHg without lOP-lowering medication. Results After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding lOP reduction （（20.59±7.94） vs. （24.85±14.39） mmHg, P=0.614）, complete success rate （88% vs. 71%, P=0.370）, formation rate of functioning blebs （65% （11/17） vs. 93% （13/14）, P=0.094）, and complications （41% （7/17） vs. 57% （8/14）, P=0.380）. lOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group. Conclusion Phacotrabeculectomy and trabeculectomy treatments exhibit similar lOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.
