    (Dove Medical Press Ltd, 2018) Mansour A.M.; Chhablani J.; Arevalo J.F.; Wu L.; Sharma R.; Sinawat S.; Sujirakul T.; Assi A.; Vélez-Vázquez W.M.; Mansour M.A.; Kayikcioglu O.; Kucukerdonmez C.; Kal A.
    Purpose: To report the visual and anatomic outcomes of albino retinal detachment (ARD) repair. Methods: Collaborative retrospective analysis of ARD. Outcome measures were number of surgical interventions, final retinal reattachment, and best corrected visual acuity (BCVA) at last follow-up. Results: Seventeen eyes of 16 patients (12 males; mean age =37.8 years) had the following complications at presentation: macula off (14), total (7) or inferior detachment (5), proliferative vitreoretinopathy (5), detectable break (16), lattice (5), horseshoe tears (9), and giant tear or dialysis (4). Mean number of interventions was 1.8 (range =1–5) and included cryopexy (15) with scleral buckle (11), and/or vitrectomy (8). Mean initial BCVA was counting finger (CF) 1 m and at last follow-up (mean 77 months) CF4m with mean improvement of 4.5 lines (early treatment diabetic retinopathy study) (P=0.05). Intraoperative choroidal hemorrhage occurred in three eyes. The retina was finally attached in 14 eyes, with residual inferior detachment in three eyes with silicone oil in situ. Silicone oil was kept in six of seven eyes because of residual inferior detachment (3) and removal of silicone oil, which led to redetachment (1) or fear of redetachment (2). Conclusion: Repair of ARD may require several interventions, with the need to keep silicone oil in several cases due to nystagmus and reduced melanin pigment. © 2018 Mansour et al.

    Intravitreal Dexamethasone Implant in Retinitis Pigmentosa-related Cystoid Macular Edema
    (Lippincott Williams and Wilkins, 2018) Mansour A.M.; Sheheitli H.; Kucukerdonmez C.; Sisk R.A.; Moura R.; Moschos M.M.; Lima L.H.; Al-Shaar L.; Arevalo J.F.; Maia M.; Foster R.E.; Kayikcioglu O.; Kozak I.; Kurup S.; Zegarra H.; Gallego-Pinazo R.; Hamam R.N.; Bejjani R.A.; Cinar E.; Erakgün E.T.; Kimura A.; Teixeira A.
    Purpose: To report the clinical outcome after intravitreal dexamethasone implant in patients with retinitis pigmentosa and cystoid macular edema. Methods: Multicenter retrospective case series of eyes with retinitis pigmentosa and cystoid macular edema that underwent intravitreal dexamethasone implant. Primary outcome measures were best-corrected visual acuity in LogMAR and central macular thickness. Statistical analyses used two-tailed comparison with Wilcoxon signed-rank test. Results: There were a total of 45 eyes from 34 patients with a mean age of 32.7 years (range 16-57) and mean follow-up of 15.5 ± 13.0 months. At Month 3 after the first injection, mean initial best-corrected visual acuity improved from 0.61 ± 0.38 (20/81) to 0.37 ± 0.16 (20/47) (P = 0.012), whereas mean central macular thickness (m) decreased from 506 ± 288 m to 311.7 ± 71.6 m (P < 0.001) and mean intraocular pressure increased from 15.7 ± 2.3 mmHg to 19.8 ± 11.0 mmHg (P = 0.01). Fourteen eyes had multiple injections (1-7 reinjections) at a mean interval of 6 months. Treatment effect was durable with multiple injections, but with seven eyes developing visually significant cataracts. Conclusion: Best-corrected visual acuity improved up to 4 months in around half of the eyes. Eyes that benefited the most were pseudophakic, steroid nonresponsive, with large initial central macular thickness, and profuse fluorescein dye leakage. © Ophthalmic Communications Society, Inc.
