Comparison of scleral buckling and vitrectomy using wide angle viewing system for rhegmatogenous retinal detachment in patients older than 35 years

To compare scleral buckling (SB) and pars plana vitrectomy (PPV) using a wide angle viewing system (WAVS) for uncomplicated phakic rhegmatogenous retinal detachment (RRD). The medical records of patients with uncomplicated phakic RRD were retrospectively reviewed. Eyes with pseudophakic or attached fovea were excluded. Patients treated with SB were classified as group B, and PPV using WAVS as group V. Primary success rate, visual acuity (VA), macular complications, and sustained subretinal fluid (SRF) were compared between groups. Seventy-two eyes were included in group B and 57 eyes in group V. Group B had better preoperative VA (1.38 ± 0.87 vs 1.84 ± 0.97 in LogMAR, P = 0.010), but worse final VA (0.51 ± 0.48 vs 0.30 ± 0.23, P = 0.012) than group V. The primary success rate of 94.7 % in group V was higher than 77.8 % in group B (P = 0.010). Final success rate was 100 % in both groups. There was no significant difference in macular complications between groups (P = 0.087). Sustained SRF was found in 22 eyes in group B (38.6 %), while only two eyes in group V exhibited sustained SRF (2.8 %, P
