Macular Thickness Measured By Optical Cohorence Tomography after Uneventful Manual Small Incision Cataract Surgery and Correlation with Postoperative Visual Acuity
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 10
Abstract
Background: Macular edema is known to cause decreased vision post operatively after cataract extraction and Intra Ocular Lens (IOL) implantation. In this study we correlated the post-operative visual acuity following uneventful Manual Small Incision Cataract Surgery(MSICS) and IOL implantation with macular thickness measured by Optical Coherence Tomography(OCT). Methods: In this study 62 patients between 45 to 90 years who were assigned to undergo MSICS with IOL implantation under local anaesthesia were selected. Detailed pre operative ophthalmic examination including BCVA using the Log MAR chart, slit-lamp examination and fundus examination was done. OCT measurements were done pre-operatively, between 1st day to 3rd day, 7th to 10th day and at 6 weeks. These measurements were then correlated with log MAR best corrected visual acuity. Results: In our study the average macular thickness increased by32.72µ (15.6%) in foveal minimum, 32.53µ(11.72%) in fovea,28.25µ (8.50%) in inner quadrant and 24.65µ (11.00%) in outer quadrant, compared to preoperative base line measurement and six weeks. A definite positive correlation between macular thickness and BCVA was observed in our study. There was no statistically significant change found in visual acuity from immediate post operative period to six weeks even though there was a linear average increase in foveal thickness up to six weeks. Conclusion: No significant change in visual acuity from immediate post operative period to six weeks was found, even though there was a linear average increase in foveal thickness up to six weeks
