Abstract

STUDY DESIGN: PROSPECTIVE COHORT STUDY
PURPOSE:ANALYSE CHANGES IN MACULAR THICKNESS IN PATIENTS OPERATED FOR TRABECULECTOMY
METHODS :IN PROSPECTIVE COHORT STUDY PATIENTS OPERATED FOR TRABECULECTOMY WERE ENROLLED FROM 2020-21. .CREATION OF FORMAT AND RETRIVAL OF DATA FROM EMR AND ANALYSED WITH SPSS 22. DESCRIPTIVE AND CROSS TABULATION USED FOR ANALYSES.P VALUE <0.05 CONSIDERED STASTICALLY SIGNIFICANT.
RESULTS:OUR COHORT CONSISTED OF 80 PATIENTS.CMT AND IOP WAS DOCUMENTED BEFORE AND AFTER TRABECULECTOMY AT MEAN INTERVAL OF 36 DAYS DURATION. MEAN MACULAR THICKNESS INCREASED FROM 246.4 TO 248.2 MICROMETER (P=0.01) AND CORRELATED POSITIVELY WITH IOP REDUCTION FROM 29.77 TO 13.22(P=0.02)
CONCLUSION:SLIGHT INCREASE IN MACULAR THICKENING WAS OBSERVED AFTER TRABECULECTOMY.IT MAY BE DUE TO REDUCTION IN INTRAOCULAR PRESSURE AFTER SURGERY AS IT LEADS TO INCREASE IN GRADIENT OF CAPILLARY/INTERCELLULAR PRESSURE LEADING TO ENHANCED FILTERATION AND FLUID ACCUMULATION IN INTERCELLULAR RETINALSPACE
