To quantify changes in photoreceptor density using adaptive optics fundus camera in patients after retinal detachment (RD) and to correlate them with macular involvement and best-corrected visual acuity.
At 1 and 3 months (M1 and M3) after vitrectomy, 194 patients underwent adaptive optics imagery in both eyes, at 5 locations, that we matched between time points using anatomical landmarks. Twenty-two patients (10 fovea-OFF [OFF] and 12 fovea-ON [ON]) had matched and analyzable adaptive optics images. We used analysis of variance for repeated measures.
Best-corrected visual acuity (logarithm of the minimum angle of resolution and Snellen equivalent [SE]) was significantly different between OFF and ON RDs at baseline: 2.0 (2.3–0.95) (SE: 20/2000) versus 0 (0.1–0) (SE: 20/20); at M1: 0.35 (0.5–0.1) (SE: 20/40) versus 0.05 (0–0.1) (SE: 20/25); and at M3: 0.25 (0.3–0.1) (SE: 20/32) versus 0 (0–0) (SE: 20/20). We observed that cone density was stable in fellow eyes between M1 and M3 (P = 0.67); decreased in treated eyes than in fellow eyes (P < 0.05); and increased postoperatively in the ON group (P = 0.02) but not in the OFF group (P = 0.97). Visual acuity and RD type were independently correlated with cone density (P = 0.004, P = 0.000).
Postoperative cone density was reduced in OFF RD, but also in the ON group, although the drop recovered during the 3-month follow-up. Cone density was significantly correlated with both visual acuity and type of RD at both time points.

After successful pars plana vitrectomy for rhegmatogenous retinal detachment, in vivo cone density estimated with adaptive optics fundus camera postoperatively showed that cone density was significantly correlated with both visual acuity and type of retinal detachment.
