Abstract

Purpose

To compare the central corneal thickness (CCT) in eyes of Korean subjects with primary angle-closure glaucoma (PACG) to other patients with glaucoma and control subjects.

Methods

Medical records of patients who underwent examination for glaucoma and pre-operative examination for cataract surgery between March 2009 and August 2012 in our clinic were reviewed. CCT was compared in normal control eyes, primary open angle glaucoma (POAG) eyes and normal tension glaucoma (NTG) eyes.

Results

The mean CCT of POAG eyes was significantly larger than that of normal control eyes, NTG eyes and PACG eyes (p = 0.027, 0.009 and 0.008, respectively). There was no significant difference in mean CCT between normal control eyes, NTG eyes or PACG eyes.

Conclusions

PACG eyes had a CCT similar to that of NTG or normal eyes in Korean subjects. J Korean Ophthalmol Soc 2014;55(3):402-407
