Abstract
To study the clinical profile and OCT evaluation (Rnfl and gcl) in NA‐AION It was an observational, cross sectional study. Thirty patients with history of sudden diminution of vision were studied in 1yr duration (Sept 2019‐ Aug 2020). A neuro‐ophthalmic examination performed on all patients including visual acuity, RAPD assessment ,colour vision, visual fields and fundus examination. Systemic evaluations were done.OCT scans were done for both eyes of each patient using nerve fibre layer and macular analysis protocol. Similar age match control group were taken. Male patients showed dominance (60%). Reduced VA, colour vision defect, reduced contrast sensitivity was observed. Average RNFL thickness in NA‐AION patients were 178.20±99.54μm,94.23±12.23 μm in healthy controls (p<0.0001). Quadrant Rnfl thickness was maximum in superior quadrant 239.83±129.87μm(p<0.01). Average GCL±IPL thickness were 68.78±18.06 μmin NA‐AION,83.30±8.32 μm in control group (p<0.0002), respectively.Sectoral GCL thinning was observed maximum in superotemporal sector 63.20±23.46μm(p<0.001). Differentials of optic neuropathy should be evaluated for defective vision, colour vision, RAPD and optic disc abnormality with field defects. OCT quantifies RNFL thickness and GCL thinning in ischemic ON.
