Ultra-Widefield Fundus Autofluorescence in Cytomegalovirus Retinitis.

: To study the role of ultra-wide field (UWF) fundus autofluorescence (FAF) in the management of CMV (cytomegalovirus) retinitis.: In this prospective, observational, non-randomized study, we followed up patients with active CMV retinitis on UWF fundus photograph (FP) and UWF-FAF.: A total of 16 patients (24 eyes) were studied. There were 13 males and mean age of patients was 37 (range 9-56) years. On UWF FP, out of 24 eyes, 13 (54.2%) had granular lesions, 3 (12.5%) had necrotizing pattern, 1 (4.1%) had a frosted branch angiitis (FBA), and 7 (29.2%) had a mixed pattern. UWF-FAF showed better delineation of borders of lesions in 7 eyes (29.1%), larger area of involvement in 8 eyes (33.3%), picked up 7 of 9 (77.77%) eyes of recurrence and helped differentiate cotton wool spots from retinitis lesion in one eye.: UWF-FAF is useful in the management of CMV retinitis.
