A pilot study regarding basic knowledge of "cortical visual impairment in children" among ophthalmologists.

PURPOSE: A pilot study was done to evaluate knowledge regarding "cortical visual impairment (CVI) in children" among ophthalmologists. METHODS: This study was conducted during the annual conference of a zonal ophthalmological society. All ophthalmologists who attended the conference were requested to participate in this study. Those who agreed were given a validated questionnaire to assess knowledge regarding CVI. Cronbach's alpha of the questionnaire was 0.6. Participants were asked to respond to multiple choice questions by choosing the single best option. The responses obtained were then evaluated. RESULTS: The total number of registered delegates in the conference was 448. A total of 103 ophthalmologists showed interest to participate in the study with a response rate of 22.9%. Only 89/103 interested delegates were included in the study as remaining were unaware of CVI. No participant gave correct answers to all questions. Although more than 80% of them knew the most common association (87%) and site of pathology (84%), only 52% were sure about clinical features and even lesser respondents (39%) knew that magnetic resonance imaging is the correct investigation of choice. The majority responded correctly that these children need eye examination (89%) and can be managed by rehabilitation through multidisciplinary approach (82%), but only 58% could recognize differential diagnoses and had a correct idea regarding the prognosis of CVI. There was no correlation between the number of patients diagnosed per month by the respondent with knowledge of the disease. CONCLUSION: In this pilot study, ophthalmologists were found to have limited knowledge regarding clinical features, investigation, differential diagnosis, and visual prognosis of CVI in children. There is a need to improve awareness regarding CVI among ophthalmologists.

Cross-sectional, observational study of anterior segment parameters using anterior segment optical coherence tomography in North Indian Population.

PURPOSE: To study the anterior segment (AS) parameters using AS optical coherence tomography (AS-OCT) in the North Indian population. METHODS: A hospital-based, observational, cross-sectional study was conducted over a period of 1 year. It included 251 normal individuals aged 20-70 years. Participants underwent imaging with AS-OCT.Ocular parameters included anterior chamber angle (ACA), iris cross-sectional area (ICSA), iris thickness (IT), and iris curvature (IC). The parameters were measured nasally and temporally for both sexes and different age groups. RESULTS: The mean age of participants was 48.3 ± 13.9 years and 50.6% were men. The ACA decreased with age whereas ICSA, IT, and IC increased with age. The ACA (P = 0.0001nasally and temporally), ICSA (P = 0.011 nasally, P = 0.027 temporally), IT750 (P = 0.001 nasally, P = 0.011 temporally), IT1500 (P = 0.002 nasally, P = 0.002 temporally), and IC (P = 0.059 nasally, P = 0.128 temporally) underwent statistically significant changes with increasing age. No significant difference was seen in parameters of different sex. CONCLUSION: In this subset of the Indian population, the change in the AC parameters with age influences the AC dimensions predisposing the eye to glaucomatous conditions. These data are applicable clinically for the assessment and surgical management of patients requiring AS surgery. Objectif: Étudier les paramètres du segment antérieur (AS) en utilisant la tomodensitométrie optique AS (AS-OCT) dans la population du nord de l'Inde. Méthodes: Une étude axée sur l'hôpital, observationnelle et transversale a été menée sur une période de 1 an. Il comprenait 251 individus normaux âgés de 20 à 70 ans. Les participants ont subi une imagerie avec AS-OCT. Les paramètres oculaires comprenaient l'angle de la chambre antérieure (ACA), la surface transversale de l'iris (ICSA), l'épaisseur de l'iris (IT) et la courbure de l'iris (IC). Les paramètres ont été mesurés par voie nasale et temporelle pour les deux sexes et différents groupes d'âge. Résultats: l'âge moyen des participants était de 48,3 ± 13,9 ans et 50,6% des hommes. L'ACA a diminué avec l'âge alors que ICSA, IT et IC ont augmenté avec l'âge. L'ACA (P = 0,0001 par voie nasale et temporelle), ICSA (P = 0,011 nasale, P = 0,027 temporellement), IT750 (P = 0,001 par voie nasale, P = 0,011 temporellement), IT1500 (P = 0,002 par voie nasale, P = 0,002 temporellement) Et IC (P = 0,059 nasal, P = 0,128 temporellement) ont subi des changements statistiquement significatifs avec l'âge. Aucune différence significative n'a été observée dans les paramètres du sexe différent. CONCLUSION: Dans ce sous-ensemble de la population indienne, la variation des paramètres CA avec l'âge influence les dimensions AC prédisposant l'oeil aux conditions glaucomateuses. Ces données sont applicables cliniquement pour l'évaluation et la gestion chirurgicale des patients nécessitant une chirurgie AS.

Congenital Double Elevator Palsy with Sensory Exotropia: A Unique Surgical Management.

PURPOSE: To report a unique surgical approach for congenital double elevator palsy with sensory exotropia. CASE REPORT: A 7-year-old boy with congenital double elevator palsy and sensory exotropia was managed surgically by Callahan's procedure with recession and resection of the horizontal recti for exotropia without inferior rectus recession, followed by frontalis sling surgery for congenital ptosis. CONCLUSIONS: Favourable surgical outcome was achieved without any complication.
