Retinal Nerve Fiber Layer and Ganglion Cell Complex Thickness Analysis in Treatment - Naive Glaucoma Patients
Aim:
To evaluate RNFL (Retinal Nerve Fiber Layer) and GCC (Ganglion Cell Complex) thickness, using SD-OCT in treatment-naive patients of primary open-angle glaucoma (POAG), primary angle-closure glaucoma (PACG) and normal-tension glaucoma (NTG) and to compare these findings with healthy controls.
Material And Methods:
The study included 150 eyes of 75 glaucoma patients (25 each of POAG, PACG, NTG) and 200 eyes of 100 controls. In this cross-sectional observational study, patients meeting the inclusion criteria underwent comprehensive ophthalmic examinations, including best-corrected visual acuity, intraocular pressure (IOP) by Goldmann applanation tonometry (GAT), gonioscopy to differentiate between open and closed angle and visual field analysis (VFA). GCC-IPL and RNFL thickness were measured using SD-OCT.
Results:
Significant thinning of RNFL was noted in all glaucoma subtypes, especially in inferior and superior quadrants (p.
