BACKGROUND The importance of age on the development of ocular conditions has been reported by numerous studies.Diabetes may have different associations with different stages of ocular conditions,and the duration of diabetes may affect the development of diabetic eye disease.While there is a dose-response relationship between the age at diagnosis of diabetes and the risk of cardiovascular disease and mortality,whether the age at diagnosis of diabetes is associated with incident ocular conditions remains to be explored.It is unclear which types of diabetes are more predictive of ocular conditions.AIM To examine associations between the age of diabetes diagnosis and the incidence of cataract,glaucoma,age-related macular degeneration(AMD),and vision acuity.METHODS Our analysis was using the UK Biobank.The cohort included 8709 diabetic participants and 17418 controls for ocular condition analysis,and 6689 diabetic participants and 13378 controls for vision analysis.Ocular diseases were identified using inpatient records until January 2021.Vision acuity was assessed using a chart.RESULTS During a median follow-up of 11.0 years,3874,665,and 616 new cases of cataract,glaucoma,and AMD,respectively,were identified.A stronger association between diabetes and incident ocular conditions was observed where diabetes was diagnosed at a younger age.Individuals with type 2 diabetes(T2D)diagnosed at<45 years[HR(95%CI):2.71(1.49-4.93)],45-49 years[2.57(1.17-5.65)],50-54 years[1.85(1.13-3.04)],or 50-59 years of age[1.53(1.00-2.34)]had a higher risk of AMD independent of glycated haemoglobin.T2D diagnosed<45 years[HR(95%CI):2.18(1.71-2.79)],45-49 years[1.54(1.19-2.01)],50-54 years[1.60(1.31-1.96)],or 55-59 years of age[1.21(1.02-1.43)]was associated with an increased cataract risk.T2D diagnosed<45 years of age only was associated with an increased risk of glaucoma[HR(95%CI):1.76(1.00-3.12)].HRs(95%CIs)for AMD,cataract,and glaucoma associated with type 1 diabetes(T1D)were 4.12(1.99-8.53),2.95(2.17-4.02),and 2.40(1.09-5.31),respectively.In multivariable-adjusted analysis,individuals with T2D diagnosed<45 years of age[β95%CI:0.025(0.009,0.040)]had a larger increase in LogMAR.Theβ(95%CI)for LogMAR associated with T1D was 0.044(0.014,0.073).CONCLUSION The younger age at the diagnosis of diabetes is associated with a larger relative risk of incident ocular diseases and greater vision loss. 展开更多

AIM:To investigate the efficacy of a new visual acuity(VA)screening method,the baby vision test for young children.METHODS:A total 105 eyes of 65 children aged 2-8y were included in the study.Acuity testing was conducted using a standardized recognition acuity chart(Snellen visual chart:at 3 m)and the baby vision model assessment.The baby vision device includes a screen,a near infrared camera and a computer.Children were seated at a measured distance of 33-40 cm from a display for testing.VA was estimated according to the highest resolution the children could follow.Decimal VA data were converted to logarithm of the minimum angle of resolution(logMAR)for statistical analysis.The VA results for each child were recorded and analyzed for consistency.RESULTS:The mean VA measured using the Snellen visual chart was 0.62±0.32,and that assessed using the baby vision test was 0.66±0.27.The 95%limit of agreement was-0.609 to 0.695,with 95.2%(100/105)plots within the 95%limits of agreement.VA values of the baby vision test were significantly correlated with those of the Snellen chart(R=0.274,P=0.005).CONCLUSION:The baby vision test can be used as a relatively reliable method for estimating VA in young children.This new acuity assessment might be a valid predictor of optotype-measured acuity later in preverbal children. 展开更多

AIM: To construct a new visual acuity measuring function for congenital nystagmus(CN) patients by studying the relationships between acuity,velocities and positions of the eye. ·METHODS: After assessing the relationship between acuity,movement velocities and positions of the eye separately,a new function,which we call the automated nystagmus acuity function(ANAF),was constructed to measure the visual acuity of CN patients. Using a high-speed digital video system working at 500 frames per second,each eye was calibrated during monocular fixation. Twenty-six recorded nystagmus data were selected randomly. Using nystagmus waveforms,the best vision position(foveation period) and visual acuity were analyzed in three groups of subjects,and then all outputs were compared with the well-known expanded nystagmus acuity function(NAFX) and ANAF. Standard descriptive statistics were used to summarize the outputs of the two programs. ·RESULTS: Foveation periods were brief intervals in the CN waveform when the image was on or near the fovea and eye velocity was relatively slow. Results showed good visual acuity happened during the period when velocity was low and the eye position was near the zero position,which fitted the foveation periods. The data analyzed with NAFX and ANAF had a correlation coefficient of 0.934276,with an average error of-0.00973. · CONCLUSION: The results from ANAF and NAFX analyses showed no significant difference. The NAFX manually identifies foveation eye positions and produces accurate measurements. The ANAF,however,can be calculated simply using the factors eye position andvelocity,and it automatically calculates the ANAF without the need to manually identify foveation eye positions. 展开更多

The purpose of this study was to examine the combined effects of knee extension strength (KES), visual acuity (VA), and knee joint pain (KP) on gait in 212 older women. Including, walking speed, cadence, were selected as gait parameters. Knee extension strength was measured by isometric knee extension strength, while knee joint pain and decreased visual acuity were evaluated by subjective judgment. The combine effect of KP and KES factors was examined. Stance time was significantly longer in persons with both-KP than in persons with no KP. In addition, people with superior KES had significantly greater values in walking speed, cadence, and step length, and lower values in stance time and walking angle than those with inferior KES. Furthermore, double support time showed that persons with both-KP have significantly greater values than persons with no or one-KP in the inferior KES group. Also, persons with the inferior KES had significantly greater values in persons with both-KP. The combine effect of KES and VA factors was examined. There are significant differences between the superior and the inferior KES groups. In conclusion, the elderly with both the factors of decreasing KES and both-KP, as compared to the elderly with just one of those factors, have markedly different gait properties. 展开更多

The purpose of this work is to evaluate the epidemiological aspects of vision problems and their repercussions in the schooling of children in Libreville and Owendo. Methodology: This transversal and descriptive study was carried out in May and June 2011. Included in the study were children in the 7th and 8th grades of the primary schools in Libreville and Owendo. For each child, an eye exam, including the subjective measure of visual acuity, was carried out using the Monoyer scale, and the color vision assessment was carried out with the Ishihara test. Any visual capacity under or equal to 7/10th in at least one eye was considered to be pathological. We gathered information about demographic characteristics, any preceding vision issues on the record, data on other medical problems on the record and the eye examination on computer cards. Results: Nine hundred and sixty-three children (416 boys and 517 girls, with a gender ratio of 0.86) were examined. The average age was 12 ± 1.7 years old. The prevalence of the drop in visual acuity was 16.2%. The prevalence of color vision anomalies was 15.5%. Complaints concerning vision problems were significantly more present from children with a drop in visual acuity (p 0.01). Visual anomalies had an impact on the children’s schoolwork, and yet, visits to the ophthalmologist’s office were few. Conclusion: The frequency of anomalies in vision justifies systematic screening in schools and organization of an appropriate treatment. 展开更多

Adequate near and intermediate visual capacity is important in performing everyday tasks,especially after the introduction of smartphones and computers in our professional and recreational activities.Primary objective of this study was to review all available reading tests both conventional and digital and explore their integrated characteristics.A systematic review of the recent literature regarding reading charts was performed based on the PubM ed,Google Scholar,and Springer databases between February and March 2021.Data from 11 descriptive and 24 comparative studies were included in the present systematic review.Clinical settings are still dominated by conventional printed reading charts;however,the most prevalent of them(i.e.,Jaeger type charts)are not validated.Reliable reading capacity assessment is done only by those that comply with the International Council of Ophthalmology(ICO)recommendations.Digital reading tests are gaining popularity both in clinical and research settings and are differentiated in standard computer-based applications that require installation either in a computer or a tablet(e.g.,Advanced VISION Test and web-based ones e.g.,Democritus Digital Acuity Reading Test requires no installation).It is evident that validated digital tests will prevail in future clinical or research settings and it is upon ophthalmologists to select the one most compatible with their examination routine. 展开更多

AIM:To focus on different visual resolution tasks under photopic and mesopic conditions in Sjogren’s syndrome patients compared to age-matched healthy controls.METHODS:The visual resolution measurements included high and low visual acuities and contrast sensitivity functions.These tests were conducted under photopic and then mesopic conditions.Twenty-one Sjögren’s syndrome patients and 21 aged-matched healthy volunteers completed all the measurements in this study.RESULTS:Sjogren’s syndrome patients have greater impairment in contrast sensitivity than standardized visual acuity.This reduction was significant under the mesopic condition.Also,Sjogren’s syndrome patients treated with pilocarpine suffer more than patients without pilocarpine treatment under low light conditions.CONCLUSION:Sjogren’s syndrome patients shows greater impairment in different visual resolution tasks due to dry eye symptoms. 展开更多
