LATE RECURRENCE OF RETINAL DETACHMENT

Abstract

Purpose: To describe and evaluate demographics, clinical features, prognostic factors, rate of success of surgery, incidence, and visual outcomes in patients with a late recurrence of rhegmatogenous retinal detachment over a 10-year period at a large tertiary referral eye center. Methods: A retrospective, observational case series of patients with late recurrence of retinal detachment, defined as redetachment after at least six months of total reattachment in non-proliferative vitreoretinopathy (PVR) rhegmatogenous retinal detachment, after pars plana vitrectomy (PPV) surgery with gas tamponade. Results: Thirty-nine patients had a late recurrence of rhegmatogenous retinal detachment of 16,396 rhegmatogenous retinal detachment operations. The mean of time between the first retinal detachment (RD) surgery and redetachment was 122.7 (SD 115) weeks. On presentation with late recurrence, 72% of eyes were pseudophakic and 64% were macula-off. In 28 eyes, small breaks were found. Thirty-eight percent had established PVR (PVR-C in 80%). Ninety-five percent underwent PPV. Gas was used in 61%. The initial secondary success rate was 64%. Initial best-corrected visual acuity was 1.32 logarithm of the minimum angle of resolution (logMAR) (6/120) and final was 0.8 logMAR (6/38; P value 0.002). Conclusion: Late recurrence of retinal detachment is rare. It is characterized by small retinal breaks that may be difficult to visualize. Although cases can be treated with favorable anatomical results, visual outcomes are often less good and the success rate is lower.
