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.

Optical coherence tomography confirmed resolution of macular edema in a diabetic patient after hemodialysis.

PURPOSE: The authors report the first case, to their knowledge, of resolution of diffuse macular edema after hemodialysis, which has been confirmed by optical coherence tomography. METHODS: A 53-year-old white woman with type 2 diabetes developed worsening macular edema and was examined in the ophthalmology clinic and scheduled for macular grid laser photocoagulation. The laser, however, was deferred for 4 weeks because she had also developed end-stage renal failure and required hemodialysis. RESULTS: When she was reviewed in the ophthalmology clinic 4 weeks later for laser therapy, it was found that her macular edema had resolved, vision had improved, and laser was unnecessary. Review at 6 months showed that the macular edema remains resolved. CONCLUSION: Ophthalmologists should be aware that hemodialysis may reduce macular edema in such patients.
