A STUDY TO CORRELATE OPTIC CUP/DISC RATIO WITH VISUAL FIELD DEFECTS IN PRIMARY OPEN ANGLE GLAUCOMA
Journal Title: International Journal of Basic and Applied Physiology - Year 2017, Vol 6, Issue 1
Abstract
Background & Objectives: This study was undertaken to assess the correlation between Vertical cup/disc (C/D) ratio found on ophthalmologic examination in Primary open angle glaucoma and loss variance which indicates local heterogenicity of visual field defect. Severity of scotomas was also assessed. Material & Methods: After comprehensive eye examination and glaucoma evaluation, 27 subjects (total 47 eyes) diagnosed with primary open angle glaucoma underwent visual field analyses on Octopus 900 computerised perimetry analyser. Data was tabulated and statistical tests were applied. Results: We found a statistically significant correlation between C/D ratio and loss variance at p<0.05. Also severity of scotomas increased in advanced cases with a higher C/D ratio. Interpretation: Patients with open angle glaucoma show progressive cupping of optic disc with more propensity of retinal fiber damage giving rise to worsening visual field defects. Regular evaluation with automated perimetry is of utmost importance and can help in better management of glaucoma.
