Abstract

Purpose: Our study evaluated changes in pRNFL and mGCL-IPL measurements on SD-OCT following cataract surgery in patients with immature senile cataracts (IMSC). Methods: 47 patients with uncomplicated IMSC underwent pre- and 1-month post-operative (phacoemulsification and IOL implantation) assessment of pRNFL and mGCL-IPL using SD-OCT (Cirrus HD-OCT, Carl-Zeiss Meditec). Only images with a quality score of 6 and above were included. Pre- and post-operative pRNFL and mGCL-IPL values were compared, and P<0.05 was considered significant. Results: Significant differences were seen in all mGCL-IPL measurements (average, minimum, and all sectors) but only in the average and temporal pRNFL. It was affected irrespective of nuclear(n=26) or posterior subcapsular(n=21) sub-type compared with the pRNFL values (only average pRNFL was affected). Conclusion: Cataract affects the measurements of mGCL-IPL greater than pRNFL on Cirrus HD-OCT despite an acceptable quality score.
