چکیده
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.
