Optical Coherence Tomography Analysis Of The Macula After Scleral Buckle Surgery For Retinal Detachment: A Diagnostic And Therapeutic Advantage

Optical Coherence Tomography Analysis Of The Macula

Abstract

Background: To study the different structural alterations in macula after scleral buckling surgery on Optical Coherence Tomography and corelate with postoperative visual acuity. Material And Methods: Total 50 patients with Rhegmatogenous retinal detachment who underwent scleral buckling surgery were included. The study has been approved by ethics committee. Clinical examination and Preoperative oct and postoperative oct on day 7, 1 month 3 month and 6 months were done. Result: After Scleral buckling Surgery post operatively after 1 week(38%),1 month(20%),3 month(8%),6 month(4%) in male and 1 week(20%),1 month(16%),3 month(6%) and 6 month(2%) in female had Persistent Subretinal fluid .Pre operative eyes with subretinal fluid Mean LogMAR VA was 2.21 which was improved to 1.60 on post operative 6 month period. p value 0.033(p value<0.05) was clinically significant suggested that resolution of subretinal fluid during 6 month period significantly improved Visual Acuity. Inner segment/Outer segment (IS/OS) junction of photoreceptor was disrupted in 23(46%) eyes with 21 eyes (54%) in macula off and 2(18%) eyes in macula on. In our study ELM was intact in 23(46%) eyes with 91% in macula on and 13% in macula off eyes. The Mean LogMAR VA in Eyes with Intact ELM was 1.71 and 1.91 in disturbed ELM signified that visual outcome depends on intactness of ELM. Conclusion: IS/OS disruption, Intact ELM and subretinal fluid may be important predictors of visual outcome after anatomically successful RRD surgery.
