A 21-Year Study of Vitreoretinal Surgery for Aphakic Retinal Detachment: Long-Term Surgical Outcomes and Complications.

PURPOSE: To determine the characteristics and outcomes of primary retinal detachment (RD) surgery in aphakic patients.

DESIGN

Retrospective case series.

PARTICIPANTS

Sixty eyes with primary aphakic RD (ARD) in 51 patients.

METHODS

A consecutive series of patients who underwent vitreoretinal surgery for primary rhegmatogenous ARD was analyzed retrospectively between 1997 and 2018 at Moorfields Eye Hospital.

MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA), surgical outcomes, and complications.

RESULTS

Mean BCVA improved from 1.31 to 1.08 logarithm of the minimum angle of resolution (logMAR; P = 0.081) over a mean follow-up period of 8.2 years. Macula-off retinal detachments showed significantly improved BCVA from 1.72 to 1.1 logMAR (P = 0.007). Mean age was 38.8 years, and the most common cause of aphakia was congenital cataract surgery (55%). The macula was attached in 45% eyes, and grade C proliferative vitreoretinopathy (PVR) was present in 12%. Operations performed were vitrectomy (88%), combined vitrectomy and scleral buckle (8%), and encirclement (3%). The final anatomic success rate was 88%, and PVR was a significant predictor of redetachment (P = 0.03; odds ratio, 20.7; 95% confidence interval, 2.8-152.2). Raised intraocular pressure was the most common postoperative complication at 30%, with a rate of de novo postoperative glaucoma of 6.7% at final follow-up.

CONCLUSIONS

We report high rates of primary and overall anatomic success for surgery in ARD surgery. Grade C PVR was a positive predictor for surgical failure. Final visual outcomes were limited by ocular comorbidity, and we report significant improved visual outcomes for macula-off ARD.
