Abstract: Aim To compare role of Optical Coherence Tomography (OCT) and Fluorescein Angiography (FA) in diagnosis of Age related macular degeneration (AMD). Materials and methods The study enrolled 140 patients. Cases included patients aged more than 50 years, both males and females, diagnosed as AMD on routine fundoscopy in either of the eye. After careful examination with slit lamp and dilated fundoscopy, OCT and FA was done and findings were analysed. Results Mean age of AMD patients was 676.54 years.71.43 % patients had Early AMD while 28.57 % had Advanced AMD. Dry AMD constituted 17.14 % while Wet AMD constituted 11.43 % of total patients. Involvement was unilateral in 46 (32.86 %) patients while it was bilateral in 94 (67.14 %) patients. Specificity of OCT was less than FA. So, using OCT as initial tool before FA, the specificity and sensitivity came out to be 0.8478 and 1 respectively. Conclusion OCT may be a good complementary imaging technique to FFA regarding the diagnosis of AMD.
