A Comparative Study of Macular Thickness in Primary open Angle Glaucoma Patients and Normal Patients.

Abstract

Aim : To compare difference of macular thickness using optical coherence tomography (OCT) in primary open
angle glaucoma (POAG)patients and normal subjects..
Materials and methods :
This Observational case control study included primary open angle glaucoma(POAG) patients(n=60eyes)and
healthy subjects in the control group(n=60eyes).All subjects underwent detailed history,general examination,and
systemic examination. Complete ocular examination included best corrected visual acuity(BCVA),slit lamp
examination, intraocular pressure(IOP),gonioscopy,dilated fundus biomicroscopy.visual fied analysis was done
using haag streit octopus 900 machine.
Optical coherence tomography imaging machine was performed using Topcon 3D OCT machine, version
8.42003.01.In both these groups,parameters analysed were macular thickness and macular volume.
Results :
The POAG group had significantly decreased values of macular thickness(11.3%) macular thickness in POAG as
compared to control (265.09 ± 12.60 vs. 235.16 ± 7.64, p<0.001). and macular volume (7.68 ± 0.46 vs. 7.00 ±
0.48, p<0.001).Thus ,macular thickness and macular volume parameters may be used for making the diagnosis of
glaucoma, especially in patients with abnormalities of disc.
