[Thésaurus HELB]:Optique:motricité oculaireRésumé : SIGNIFICANCE: This study confirmed the application of the Convergence Insufficiency Symptom Survey (CISS) in distinguishing children with oculomotor dysfunction (OMD) from those with normal binocular vision (NBV) but not in distinguishing children with accommodative insufficiency (AI). PURPOSE: The purpose of this study was to determine the application of the CISS for quantifying symptoms in children aged 9 to 18 years with AI or OMD. METHODS: All participants (aged 9 to 18 years) underwent comprehensive binocular vision tests including visual acuity, cover test, near point of convergence, fusional vergence, accommodative amplitude, and the Developmental Eye Movement test to ascertain the presence of any vision conditions. According to the examination outcomes, participants were divided into four groups: NBV group, AI group, OMD group, and a group with both AI and OMD (AI-OMD). The CISS was individually administered to each participant. An ANOVA and a receiver operating characteristic curve were performed to evaluate the ability of the CISS to quantify symptoms in AI and OMD. RESULTS: A total of 82 participants were qualified for this study, with 18 in the NBV group, 21 in AI, 16 in OMD, and 27 in AI-OMD group. The mean CISS score was significantly different among the four groups (F = 4.19, P = .008). Post hoc tests showed significantly higher CISS scores in the OMD group than the NBV (P = .01) and the AI (P = .03) groups, but no differences were detected among other groups. Receiver operating characteristics curve showed a significant effect of the CISS score on predicting an OMD (area under curve = 0.78, P = .006). Using a CISS score of ≥15, good discrimination of OMD was obtained. CONCLUSIONS: Children with OMD (Developmental Eye Movement type II or IV) had higher CISS scores than ones with NBV. Using the CISS, children with AI did not report worse symptoms than children with NBV.

Low-dose atropine is one of the leading treatments of myopia progression in children. However, the effect of low-dose atropine on binocular vision measurements has not been thoroughly studied.
PURPOSE
This study aimed to determine the effect of 0.01, 0.03, and 0.05% atropine on visual acuity, pupil size, binocular vision, and accommodation in children aged 6 to 17 years.
METHODS
Forty-six children (28 girls and 18 boys) were randomized into four groups: placebo (n = 10) and 0.01% (n = 13), 0.03% (n = 11), and 0.05% (n = 12) atropine. One drop of atropine or placebo was administered into each eye once. The following measurements were collected before applying the eye drops and 30 minutes, 60 minutes, and 24 hours after application of eye drops: habitual visual acuity at distance and near, pupil size, dissociated phoria at distance and near, negative and positive fusional vergence, near point convergence, near point convergence stamina and fragility, accommodative lag, and amplitude of accommodation. Repeated-measures analysis of variance was used, and P < .05 was considered statistically significant.
RESULTS
Differences in pupil diameters under photopic and scotopic conditions were statistically significant when comparing all three atropine groups with placebo over time (P < .001). Pupil size in both the 0.03 and 0.05% atropine groups was enlarged from baseline at the 30-minute, 60-minute, and 24-hour time points (P < .05) in both photopic and scotopic conditions. Pupil size in the 0.01% atropine group had minimal change, and only the scotopic 60-minute time point was statistically significant (P = .02). All three concentrations of atropine eye drops have no significant effect on accommodation, binocular vision measurements, or visual acuity compared with the control group.
CONCLUSIONS
Pupil size was significantly enlarged by 0.03 and 0.05% atropine in both photopic and scotopic conditions. Low-dose atropine eye drops have no significant effect on accommodation, binocular vision measurements, or visual acuity compared with control.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Tests de visionMots-clés : diabetic retinopathy vision tests vision screening Résumé : SIGNIFICANCE: Automated low-contrast letter acuity (LCLA) has several advantages: consistent luminance, reduced chance of individuals memorizing test letters, and convenient and accurate visual acuity reporting functions. Although automated LCLA might report slightly worse acuity than Sloan LCLA chart, considering its advantages, it may be a viable alternative to Sloan LCLA chart in clinical practice and research. PURPOSE: The purpose of this study was to determine the repeatability of an automated LCLA measurement and its agreement with the Sloan LCLA chart test in normal participants and reduced-vision participants. METHODS: Adult participants (n = 49) were measured with both automated Early Treatment Diabetic Retinopathy Study and Sloan LCLA tests, including normal and reduced-vision groups. Low-contrast letter acuity at two contrast levels (2.5 and 10%) was measured at 3 m in a random sequence with both LCLA tests. To test repeatability, participants were retested 1 week later. Repeatability of the two tests between two visits and agreement between automated and Sloan LCLA tests were evaluated using 95% limits of agreement. RESULTS: In terms of the 95% limits of agreement, the repeatability of both tests was as follows: automated LCLA at 2.5%, ±0.26; automated LCLA at 10%, ±0.22; Sloan LCLA at 2.5%, ±0.23, and Sloan LCLA at 10%, ±0.16. The agreement of the two tests was as follows: ±0.19 at 2.5% and ±0.24 at 10%. The automated LCLA at 2.5 and 10% levels was generally reported one-half to one logMAR line lower than Sloan LCLA (mean differences, −0.04 at 2.5% and −0.13 at 10%; paired t test, P < .05). CONCLUSIONS: The automated LCLA test shows fairly good test-retest repeatability at both 2.5 and 10% contrast levels. The agreement between the automated and the Sloan low-contrast letter acuity tests was comparable with test-retest agreement. Although the automated LCLA test reports slightly worse acuity than the Sloan LCLA test, it could be an appropriate alternative to the Sloan LCLA test.
