Objective Cognitive impairment(CI)in older individuals has a high morbidity rate worldwide,with poor diagnostic methods and susceptible population identification.This study aimed to investigate the relationship between different retinal metrics and CI in a particular population,emphasizing polyvascular status.Methods We collected information from the Asymptomatic Polyvascular Abnormalities Community Study on retinal vessel calibers,retinal nerve fiber layer(RNFL)thickness,and cognitive function of 3,785participants,aged 40 years or older.Logistic regression was used to analyze the relationship between retinal metrics and cognitive function.Subgroups stratified by different vascular statuses were also analyzed.Results RNFL thickness was significantly thinner in the CI group(odds ratio:0.973,95%confidence interval:0.953–0.994).In the subgroup analysis,the difference still existed in the non-intracranial arterial stenosis,non-extracranial carotid arterial stenosis,and peripheral arterial disease subgroups(P<0.05).Conclusion A thin RNFL is associated with CI,especially in people with non-large vessel stenosis.The underlying small vessel change in RNFL and CI should be investigated in the future. 展开更多

AIM:To investigate the risk and protective factors associated with the retinal nerve fiber layer defect(RNFLD)in a Chinese adult population.METHODS:This study was a cross-sectional populationbased investigation including employees and retirees of a coal mining company in Kailuan City,Hebei Province.All the study participants underwent a comprehensive systemic and ophthalmic examination.RNFLD was diagnosed on fundus photographs.Binary logistic regression was used to investigate the risk and protective factors associated with the RNFLD.RESULTS:The community-based study included 14440 participants.There were 10473 participants in our study,including 7120 males(68.0%)and 3353 females(32.0%).The age range was 45-108y,averaging 59.56±8.66y.Totally 568 participants had RNFLD and the prevalence rate was 5.42%.A higher prevalence of RNFLD was associated with older age[P<0.001,odds ratio(OR):1.032;95%confidence interval(CI):1.018-1.046],longer axial length(P=0.010,OR:1.190;95%CI:1.042-1.359),hypertension(P=0.007,OR:0.639;95%CI:0.460-0.887),and diabetes mellitus(P=0.019,OR:0.684;95%CI:0.499-0.939).The protective factors of RNFLD were visual acuity(P=0.038,OR:0.617;95%CI:0.391-0.975),and central anterior chamber depth(P=0.046,OR:0.595;95%CI:0.358-0.990).CONCLUSION:In our cross-sectional community-based study,with an age range of 45-108y,RNFLD is associated with older age,longer axial length,hypertension,and diabetes mellitus.The protective factors of RNFLD are visual acuity and central anterior chamber depth.These can help to predict and evaluate RNFLD related diseases and identify high-risk populations early. 展开更多

BACKGROUND In this paper,we present a 9-year-old boy who demonstrates a complex interplay between myopia progression,axial length(AL)extension,and retinal nerve fiber layer(RNFL)thickness loss in both eyes.Additionally,concurrent optic neuritis has directly impacted RNFL thickness in his right eye,and its potential indirect influence on RNFL and macular ganglion cell layer(mGCL)thickness in his left eye is also noteworthy.CASE SUMMARY A 9-year-old boy with bilateral myopia presented with diminished vision and pain in his right eye due to optic neuritis,while his left eye showed pseudopapilledema.Steroid therapy improved his vision in the right eye,and 16-mo follow-up revealed recovery without recurrence despite myopia progression.Follow-up optical coherence tomography conducted 16 mo later revealed a notable thinning of the RNFL in both eyes,especially along with a reduction in mGCL thickness in the left eye.This intricate interaction between optic neuritis,myopia,and retinal changes underscores the need for comprehensive management,highlighting potential long-term visual implications in young patients.CONCLUSION The progression of myopia and AL extension led to the loss of RNFL thickness in both eyes in a 9-year-old boy.Concurrently,optic neuritis directly affected RNFL thickness in his right eye and may indirectly play a role in the thickness of RNFL and mGCL in his left eye. 展开更多

The ganglion cell complex thickness was not significantly changed in both groups(P all 】0.05). The RNFL thickness was statistically less 30 min after surgery in both groups(P=0.014, P 【0.001), but the influence was less in Ziemer group than that in Moria group(P =0.038).However, the RNFL thickness had recovered to the preoperative level only 1d after surgery.·CONCLUSION: The suction of femtosecond laser and mechanical microkeratome led to the increase in macular central fovea thickness and the decrease in RNFL thickness values at the early stage after LASIK. The effect of suction on macular and the RNFL thicknesses in Ziemer group is smaller than that in Moria group. 展开更多

AIM:To investigate peripapillary retinal nerve fiber layer (RNFL), macula and ganglion cell layer thicknesses (GCC) in amblyopic eyes with spectral domain optical coherence tomography (SD-OCT). METHODS:Thirty six patients with a history of unilateral amblyopia and thirty two children who had emmetropia without amblyopia were included in this study. In this institutional study, 36 eyes of 36 patients with amblyopia (AE), 36 fellow eyes without amblyopia (FE), and 32 eyes of 32 normal subjects (NE) were included. RNFL, GCC and macular thickness measurements were performed with RS-3000 OCT Retina Scan (Nidek Inc CA. USA). RESULTS:The mean global thicknesses of the RNFL were 113.22 ±21.47, 111.57 ±18.25, 109.96 ±11.31μm in the AE, FE, and NE, respectively. There was no statistically significant difference for mean global RNFL thickness among the eyes (P =0.13). The mean thicknesses of the macula were 258.25±18.31, 258.75±19.54, 248.62±10.57μm in the AE, FE and NE, respectively. There was no statistically significant difference for thickness of macula among the eyes (P =0.06). The GCC was investigated into two parts:superior and inferior. The mean thicknesses of superior GCC were 102.57 ±13.32, 103.32 ±10.64, 100.52 ± 5.88μm in the AE, FE, and NE, respectively. The mean thicknesses of inferior GCC were 103.82 ±12.60, 107.82 ± 12.33, 105.86±10.79μm in the AE, FE and NE, respectively. There was no statistically significant difference for thickness of superior and inferior GCC between the eyes (P =0.63, P =0.46). ·CONCLUSION:The macular thicknesses of AE and FE were greater than the NE, although it was not statistically significant. Amblyopia does not seem to have a profound effect on the RNFL, macula and GCC. 展开更多

To discuss the possibility of detecting tendency of glaucoma in this population by using spectral domain optical coherence tomography(3D-OCT-2000 Spectral domain).·METHODS: After polysomnographic study, all subjects(64 OSAS patients and 40 controls) underwent detailed ophthalmological examination. After these examinations,patients with glaucoma and patients who had ophthalmological and/or systemic disease were excluded from the study.Totally, 20 patients in OSAS group and five patients in controls were excluded from the study in the first examination and follow-up period. The RNFL thickness was assessed with OCT. Forty-four OSAS patients and 35 control subjects were followed up for12 mo. RNFL thickness change and OSAS patients were evaluated for severity of disease by Apnea-Hypopnea Index(AHI).·RESULTS: Forty-four OSAS patients and 35 controls were enrolled in the study. Statistically significance was found between OSAS patients and controls at the 12 thmo.Average RNFL thickness was found to be significantly lower in last measurements in OSAS patients when compared with first measurements and control subjects(P 【0.001, 0.002, respectively). There was a statistically significant correlation among AHI, and RNFL thickness(P 【0.05).·CONCLUSION: The results suggest that the patients with OSAS were related with a proportional decrease in the RNFL thickness. These patients should be followed up regularly for glaucomatous changes. Detecting more RNFL thinning in severe OSAS was important. 展开更多

AIM: To analyze the diagnostic capabilities of peripapillary retinal nerve fiber layer(p RNFL) thickness and segmented inner macular layer(IML) thickness measured by spectraldomain optical coherence tomography for detection of early glaucoma. METHODS: Fifty-three patients with primary open angle glaucoma(POAG), 60 patients with normal tension glaucoma(NTG) and 32 normal control subjects were enrolled. Thicknesses of p RNFL, total macular layers(TML), and the IML, including macular RNFL(m RNFL) and macular ganglion cell layer(m GCL) were assessed. The areas under the receiver operating characteristic curves(AROC) were calculated to compare the diagnostic power of different parameters. RESULTS: There were no differences in the parameters of p RNFL, TML, and IML between POAG and NTG groups. The thicknesses of superior and inferior m GCL showed significant correlation with mean deviation of visual field(R2=0.071, P=0.004; R2=0.08, P=0.002). The m GCL thickness significantly correlated with the p RNFL thickness in the superior and inferior quadrants(R2=0.156, P〈0.001; R2=0.407, P〈0.001). The thickness of the inferior-outer sector of macula had greater AROCs than those in the inferior-inner sector of macula. The AROCs for superior(0.894) and inferior(0.879) p RNFL thicknesses were similar with the AROCs for superior(0.839) and inferior m GCL(0.864) thicknesses. Sensitivities at 80% specificity for global p RNFL, inferior-outer m GCL and inferior-outer m RNFL thicknesses were 0.938, 0.867, and 0.725, respectively. CONCLUSION: The diagnostic capability of the m GCL thickness is comparable to that of the p RNFL thickness in patients with early glaucoma. The inferior-outer sector of IML has a better diagnostic capability than the inferiorinner sector of IML for detection of early glaucoma. 展开更多

AIM: To compare the retinal nerve fiber layer (RNFL) thickness in the morning and evening in Thai patients with varying degrees of obstructive sleep apnea/ hypopnea syndrome (OSAHS). METHODS: In this cross-sectional study, potential OSAHS patients at Siriraj Hospital underwent polysomnography to determine the severity of OSAHS and an eye examination (including best corrected visual acuity, slit-lamp examination, and Goldmann applanation tonometry). RNFL thickness was recorded once in the morning and once in the evening, using spectral domain optical coherence tomography. Thickness was expressed as an average and given for each quadrant. Patients with ocular or systemic diseases that might affect RNFL thickness were excluded. RESULTS: Forty-one eyes of 41 patients were classified into 40SAHS groups. The average and mean RNFL thickness in most of the four quadrants of the severe OSAHS group trended toward being less than those in the comparable quadrants of the other groups in both the morning and evening. In the moderate OSAHS group, the average RNFL thickness and temporal and superior quadrant thickness in the morning were significantly higher than in the evening (P=0.01, P=0.01, and P=0.03, respectively). In the severe OSAHS group, the inferior quadrant thickness in the morning was significantly higher than in the evening (P =0.03). CONCLUSION: The RNFL thickness in the morning was higher than in the evening in moderate OSAHS. 展开更多

AIM:To explore the topographic distribution features of choroidal thickness(CT)and retinal nerve fiber layer thickness(RNFLT),and determine the relationship between CT and ocular parameters in school-aged children.METHODS:The healthy school-aged children with low ametropia or emmetropia in Wenzhou were recruited for this cross-sectional study.With high-density optical coherence tomography(HD-OCT)combined with MATLAB software,the CT and RNFLT values in the macular area were measured at different locations and compared.Statistical analyses were performed to evaluate the correlation between CT and ophthalmic parameters,such as spherical equivalent(SE)and the axial length(AL).RESULTS:A total of 279 school-aged children with8.00±1.35 years of mean age(range,6-10 y)were included.The mean AL was 23.66±0.86 mm.The mean CT in CT-C(264.31±48.93μm)was thicker than that in CT-N1(249.54±50.52μm),and the average CT in the parafoveal region was also thicker than that in CT-N2(235.65±50.63μm).The subfoveal CT also varied substantially across refractive errors(P<0.001),and those with myopia(250.59±47.01μm)exhibited a thinner choroid compared with those with emmetropia(278.74±48.06μm).CT negatively correlated with AL(y=-21.72 x+779.17;R^2=0.1458),and positively correlated with SE(y=15.76 x+271.9;R^2=0.0727.OD;y=18.31 x+269.8;R^2=0.1007.OS).The average RNFLT was thickest in the peripapillary region(236.35±19.03μm),the mean RNFLT-S(131.10±15.16μm)was thicker than the RNFLT-I(128.20±16.59μm),and the mean RNFLT-T(76.54±11.99μm)was thicker than the RNFLT-N(64.28±8.55μm).The variations in the RNFLT between quadrants did differ between those with myopia and emmetropia(P<0.05).CONCLUSION:We establish demographic information for the choroid and RNFLT.These findings provide information that should be considered in future analyses of the CT and RNFLT in OCT studies in school-aged children. 展开更多

AIM: To compare retinal artery-vein diameters(RAVDs)of patients with pseudoexfoliation(PSX) syndrome with healthy controls and investigate the correlations between retinal nerve fiber layer(RNFL) thickness parameters and RAVDs.METHODS: Seventeen eyes with PSX and 17 eyes of age-matched controls were included in the study. All participants underwent routine ophthalmological examination, Humphrey visual field and RNFL examination by using Stratus OCT. Retinal images were obtained by using a retinal camera(Topcon 501X).RAVDs were measured from inferior nasal, inferior temporal, superior nasal and superior temporal arcuates by using IMAGEnet software. Superior, inferior, nasal,temporal and average RNFL thicknesses were recorded.RAVDs and RNFL parameters in groups and correlations were analyzed by Mann-Whitney U and Spearmann correlation tests.RESULTS: Only inferior quadrant and average RNFL thickness were detected thinner in the PSX group compared with control group(P =0.009, P =0.038,respectively). No statistically significant difference regarding RAVDs was found between two groups.CONCLUSION: RAVDs seems to be comparable in the PSX and control group. RNFL is thinner in the inferior quadrant in the PSX group. RNFL thickness and RAVDs show significant correlations in both groups. This correlation doesn’t seem to be specific to PSX. 展开更多

The two experimental groups were the normal group ( =20 rats) and the optic nerve transected group ( =16 rats). The latter group included 4 groups ( =4 /group) surviving for 1 day, 3, 5 and 7 days. Then the RNFL thickness of the same retina area was also measured by NF -200 immunohistochemical staining method. Linear regression was used to analyze the correlation between the data obtained from these two methods. ·RESULTS: The RNFL thickness of normal right eyes around optic disc by OCT was 72.35 ±5.71μm and that of the left eyes was 72.65 ±5.88μm ( =0.074). The RNFL thickness of the corresponding histological section by immunohistochemistry was 37.54 ±4.05μm (right eyes) and 37.38 ±4.23μm (left eyes) ( =0.059). There was a good correlation between the RNFL thickness measured by OCT and that measured by histology (R 2 =0.8131). After optic nerve transection, the trend of the RNFL thickness was thinner with the prolonged survival time. The correlation of the thickness detected by the above two methods was approximately (R 2 =0.8265). Value of the RNFL thickness in rats around optic disc measured by OCT was obviously higher than that measured by common histological measurement in normal adult rats and optic nerve transected rats. ·CONCLUSION: The RNFL thickness measured by OCT has a strong correlation with that measured by histological method. Through OCT scanning, we found that the thickness of RNFL gradually becomes thinner in a time-dependent manner. 展开更多

AIM: To assess the reproducibility of Cirrus high-definition optical coherence tomography(HD-OCT; Carl Zeiss Meditec, Dublin, CA, USA) for analysis of peripapillary retinal nerve fiber layer(RNFL) thickness in glaucomatous eyesMETHODS: Forty-five eyes(one eye from each glaucomatous patient) were imaged with Cirrus HD-OCT.Each eye was imaged three times by two separate operators. Intraclass correlation coefficient(ICC),coefficient of variation(CV), and test-retest variability were evaluated for both intraobserver and interobsever measurementsRESULTS: In intraobserver measurements, the average RNFL thickness ICC was 0.983. CV and test-retest variability were 2.3% and 4.4 μm respectively. In quadrants ICC ranged from 0.886 to 0.956, the lowest associated with nasal quadrant and CV ranged from 3.6%to 7.7%. In interobsever measurements, the average RNFL thickness ICC was 0.979. CV and test-retest variability were 2.4% and 4.5 μm respectively. In quadrants ICC ranged from 0.886 to 0.957, the lowest associated with nasal quadrant and CV ranged from 3.8%to 8.6%.CONCLUSION: The reproducibility of Cirrus OCT for RNFL thickness is sufficiently good to be useful clinically as a measure of glaucoma progression. 展开更多

AIM: To evaluate the retinal nerve fiber layer(RNFL)thickness changes in patients with obstructive sleep apnoea syndrome(OSAS), and detect possible prevalence of glaucoma in this population.METHODS: Comprehensive studies were conducted on the Cochrane Library, Pub Med and Embase through March, 2015. Only studies that fit the selection criteria about RNFL and OSAS would be included. For the measures, we calculated the 95% confidence interval(CI)and weighted mean differences(WMD). The systematic review and Meta-analysis was performed by Rev Man 5.2software.RESULTS: Nine case-control studies were analyzed containing a total of 1086 cases and 580 controls.Average RNFL thickness in OSAS was reduced significantly compared with healthy controls in random effects model(WMD =-2.56, 95% CI:-4.82 to-0.31, P =0.003, I2=57%). A significant RNFL thickness reduction were found between the two groups in inferior quadrant(WMD =-3.11, 95% CI:-5.53 to-0.69, P =0.01), superior quadrant(WMD =-2.37, 95% CI:-4.7 to 0.04, P =0.05). In nasal quadrant(WMD =-2.54, 95% CI:-6.53 to 1.45, P =0.21) and temporal quadrant(WMD=-1.26, 95% CI:-2.19 to 0.47, P =0.15) there was no difference of RNFL thickness between the two groups.CONCLUSION: The results show that RNFL thickness is lower in patients with moderate or severe OSAS than in normal subjects or patients with mild OSAS according to the nine homogeneity studies. 展开更多

AIM: To compare the peripapillary retinal nerve fiber layer(RNFL) thickness measured via optical coherence tomography(OCT) between different groups of myopia severity and controls. METHODS: This was a prospective cross-sectional study. All subjects underwent a full ophthalmic examination, refraction, visual field analysis and A-scan biometry. Myopic patients were classified as low myopia(LM) [spherical equivalent(SE) from greater than-0.5 D, up to-3.0 D], moderate myopia(MM; SE greater than-3.0 D, up to-6.0 D) and high myopia(HM; SE greater than-6.0 D). The control group consisted of emmetropic(EM) patients(SE from +0.5 D to-0.5 D). A Zeiss Cirrus HD-OCT machine was used to measure the peripapillary RNFL thickness of both eyes of each subject. The mean peripapillary RNFL thickness between groups was compared using both analysis of variance and analysis of covariance.RESULTS: A total of 403 eyes of 403 subjects were included in this study. The mean age was 31.48±10.23 y. There were 180(44.7%) eyes with EM, 124(30.8%) with LM, 73(18.1%) with MM and 26(6.5%) with HM. All groups of myopia severity had a thinner average RNFL than the EM group, but after controlling for gender, age, and axial eye length, only the HM group differed significantly from the EM group(P=0.017). Likewise, the superior, inferior and nasal RNFL was thinner in all myopia groups compared to controls, but after controlling for confounders, only the inferior quadrant RNFL was significantly thinner in the HM group, when compared to the EM group(P=0.017). CONCLUSION: The average and inferior quadrant RNFL is thinner in highly myopic eyes compared to emmetropic eyes. Refractive status must be taken into consideration when interpreting the OCT of myopic patients, as RNFL thickness varies with the degree of myopia. 展开更多

AIM: To determine the effect of multiple injections of ranibizumab or bevacizumab on retinal nerve fiber layer (RNFL) and intraocular pressure (IOP) in patients with age-related macular degeneration (AMD). ·METHODS: This retrospective study includes 35 eyes of 35 patients treated with intravitreal bevacizumab (IVB, 1.25mg/0.05mL) and 30 eyes of 30 patients with intravitreal ranibizumab (IVR, 0.5mg/0.05mL) who had Fast RNFL analysis (Stratus TM ); IOP measurements were taken 30 minutes and 24 hours after each injection. RESULTS: The mean ages were 68.0±7.5 and 69.1±7.7 years in the IVR and IVB groups, respectively (P =0.55). They underwent (6.3±1.9) and (5.1±1.3) injections (P = 0.07) over (13.6±2.1) and (14.05±2.6) months (P =0.45) in the IVR and IVB groups, respectively. Changes in overall and temporal RNFL thickness in IVR-treated eyes (105.3± 6.9μm and 74.4±11.2μm) were not different from those in untreated eyes in the IVR group (104.6±8.4μm and 75.1±12.6μm) (P =0.57 and P =0.41, respectively). Similarly, overall and temporal RNFL thickness in IVB-treated eyes (105.8±8.1μm and 74.5±11.8μm) were not different from those in untreated eyes in the IVB group (104.6±8μm and 74.8±12.9μm) (P=0.42 and P=0.80, respectively). The frequencies of IOP rise (P=0.60) and changes in RNFL thickness from baseline (P =0.16) were comparable between groups. CONCLUSION: Repeated intravitreal injection of ranibizumab or bevacizumab does not seem have adverse effects on RNFL thickness or IOP in wet AMD patients. 展开更多

AIM:To compare the damage pattern of the peripapillary retinal nerve fiber layer(pRNFL)and the macular ganglion cell-inner plexiform layer(mGCIPL)between early glaucomatous and non-glaucomatous optic neuropathy(EGON and NGON).METHODS:It is a cross-sectional study.Thirty-eight healthy controls,74 EGONs and 70 NGONs with comparable average pRNFL loss were included.The NGON group included 23 eyes of optic neuritis(ON),13 eyes of hereditary optic neuropathy(HON),19 eyes of toxic optic neuropathy(TON)and 15 eyes of compressive neuropathy(CON).The sectoral pRNFL and mGCIPL thickness obtained by high definition optical coherence tomography were analyzed.RESULTS:Compared to normal controls,the pRNFL thickness in all quadrants showed a decrease in both EGON and NGON group(P<0.001),but the average pRNFL thickness of EGON group was not different to that of NGON group(P=0.94).The inferior and superior pRNFL was thinner in EGON group compared to NGON group(P<0.001).The temporal pRNFL was thinner in NGON group compared to EGON group(P<0.001).No statistically significant difference was found in nasal pRNFL between EGON and NGON.While the nasal pRNFL was thinner in CON than other three types of NGON(P=0.01),no statistically significant difference was found in other three quadrantal pRNFL among the four types of NGON(P>0.05).The mGCIPL of EGON and NGON group were thinner than control group(P<0.001).In EGON group the severest sites of mGCIPL reduction was located at inferotemporal and inferior sectors.While,compared to EGON group,the average mGCIPL of NGON groupwere significantly thinner,especially in superonasal and inferonasal sectors(P<0.001).CONCLUSION:The damage pattern of pRNFL and mGCIPL caused by glaucoma is distinct from other NGON such as ON,TON,HON and CON,and this characteristic damage pattern is helpful in differentiating early glaucoma from other NGON. 展开更多
