Abstract

Purpose

To evaluate the ultrastructural changes in the macula after successful repair of rhegmatogenous retinal detachment (RRD) using spectral domain optical coherence tomography (sdOCT) and fundus autofluorescence (FAF) imaging

Methods

Simultaneous sdOCT (Topcon 2000 FA plus) and FAF imaging were performed with a system for FAF imaging using a fundus camera that included Spaide Autofluorescence filters available on IMAGEnet.

Results

31 patients with macular-off RRD and 2 with macular-on RRD were recruited. Post operative visual acuity ranged from 20/400 to 20/20. SdOCT images were normal in 18 eyes (54.5%), revealed macular edema in 9 eyes (27.2%), macular hole in 2 eyes (6%), macular pucker in 3 eyes (9%), submacular fluid in 2 eyes (6%). Fundus autofluorescence imaging of the macula were normal in 13 eyes (39.3%).There were central abnormalities in 14 eyes. Patients with abnormal FAF were also associated with poor postoperative BCVA (p<0.001)

Conclusion

The present study demonstrates the ultrastructural changes assessed with simultaneous FAF and sdOCT and their relation with visual outcome
