Abstract
 Background: Successful reattachment of the macula after
 RD is often associated with incomplete visual recovery. Even
 with a normal-appearing macula on examination, patients
 often experience visual impairment. Fundus autfluorescence
 has been used to investigate the morphological and functional  changes occurring after RD repair following vitrectomy.
 Aim of the Work: To investigate the structure-function
 relationship of the macula, by correlating fundus autofluorescence and visual acuity following successful repair of rhegmatogenous retinal detachment.
 Material and Methods:  Forty-five eyes underwent surgical
 repair of RRD followed by FAF imaging one and three months  post-operative. FAF findings were correlated with postoperative BCVA.
 Results:  Forty-five eyes achieved complete post-operative
 reattachment with 95.6% SOSR. Mean preoperative logMAR
 visual acuity showed significant difference with mean postoperative logMAR BCVA (p 0.001). The values of BCVA
 showed significant difference between eyes showing hyperautofluorescence on FAF imaging and eyes not showing hyperautofluorescence (p=0.015).
 Conclusion:  Fundus autofluorescence is a recent noninvasive imaging modality that evaluates the function and
 health of the photoreceptor and the RPE layers showing great
 advantage in analyzing the macular function abnormality.
