Abstract

Purpose : To report the incidence of post-operative retinal displacement detected on fundus autofluorescence (FAF) imaging following rhegmatogenous retinal detachment (RRD) repair with pars plana vitrectomy (PPV), scleral buckle (SB), or PPV/SB.

Methods : Single-center, prospective consecutive series conducted at Wills Eye Hospital (Philadelphia, PA, USA). Optos (Dunfermline, UK), FAF images were performed in eyes post RRD repair between April and December 2020. Images were assessed by two independent graders, masked to surgical technique. Retinal displacement was identified by imprinted retinal vessels on FAF images.

Results : Ninety-four eyes of 88 patients (73% male, mean age 62(±13) years) were included. Nineteen eyes (21%) had a macula-on RRD, 75 (79%) had a macula off RRD. Thirty-two eyes (34%) had proliferative vitreoretinopathy (PVR). Forty-four (46.8%) eyes underwent PPV alone, 9 (9.6%) underwent SB alone, and 41 (43.6%) underwent combined PPV/SB. The mean time from surgical procedure to FAF imaging was 112 days. A total of 9 eyes (9.6%) had retinal vessel imprinting on FAF consistent with retinal displacement. The mean (±SD) displacement was 0.18 mm (± 0.11; range 0.09-0.4 mm). 5 of 44 (11.3%) PPV patients and 4 of 41 (9.8%) of PPV/SB patients had displacement. No displacement was found in the SB only patients. There was no statistically significant difference in the proportion of eyes with displacement between the three surgical groups (p=0.88). All observed displacement involved the inferior vasculature. Two cases of displacement were found in patients with PVR (n=32, 9.1%), and 7 were found in patients without PVR (n=62, 11.3%; p=0.71). Mean (±SD) preoperative logMAR visual acuity was 1.46 (±0.96; Snellen equivalent 20/570) and mean (±SD) postoperative logMAR visual acuity was 0.55 (±0.37; Snellen equivalent 20/70, p<0.001). Among patients with macula-off RRD, the mean (±SD) postoperative logMAR visual acuity in the group without displacement (0.51 ± 0.34, Snellen equivalent 20/64) was significantly better than those with displacement (0.8 ± 0.37; Snellen equivalent 20/126, p= 0.035).

Conclusions : Retinal displacement after incisional retinal detachment repair occurs in approximately 10% of cases. PPV and PPV/SB showed a similar percentage of displacement. In eyes with macula-off detachments, those with displacement had worse postoperative visual outcomes compared to those without detectable displacement.
