Abstract

AMAÇ: Pupilla büyüklüğünün oküler aberasyonlara etkisini değerlendirmekYÖNTEMLER: Çalışmaya 30 erkek, 30 kadın olmak üzere 60 sağlıklı yaş aralığı 20-50 olgu alındı. Oküler aberasyonlar 60 sağlıklı olgunun 60 gözünde ölçüldü. Olgular tropikamid damlatılmadan önce ve sonra olmak üzere iki gruba ayrıldı. Yaş ve cinsiyetin yüksek sıralı ve sferik aberasyon değerlerine etkisi incelendi. Olguların oküler aberasyon ve pupil çapı ölçümleri Nidek OPD SCAN cihazı ile yapıldı.BULGULAR: Dilatasyon sonrası yüksek sıralı aberasyon değerleri dilatasyon öncesi değerlere göre anlamlı derecede yüksek bulundu p0.05 . SONUÇ: Pupil büyüklüğü yüksek sıralı ve sferik aberasyonları artırır

Keywords

Pupil büyüklüğü, yüksek sıralı aberasyon, sferik aberasyon.

Effect of Pupillary Size on Ocular Aberrations

Abstract

OBJECTIVE: To investigate the effect of pupil size on ocular aberrationsMETHODS: SSixty healthy subjects 30 male and 30 female were enrolled the study. Age range varies 20 to 50 years. The subjects were given tropicamide drops for mydriasis. Aberrations were measured before and after the mydriasis. The effect of age and gender on spherical aberration values was investigated. Ocular aberrations and pupil size measurements of the subjects were performed by Nidek OPD scan.RESULTS: High order aberrations values after the dilatation were significantly higher than the values obtained before the dilatation p0.05 . CONCLUSION: Dilatation of the pupil cause an increase in high order and spherical aberrations

Keywords
