PURPOSE: To evaluate the efficacy of arteriovenous (AV) sheathotomy with internal limiting membrane peeling for persistent or recurrent macular edema after intravitreal triamcinolone injection and/or laser photocoagulation in branch retinal vein occlusion. METHODS: Twenty-two eyes with branch retinal vein occlusion (BRVO) with recurrent macular edema underwent vitrectomy with AV sheathotomy and internal limiting membrane peeling. All eyes had previous intravitreal triamcinolone injection and/or laser photocoagulation for macular edema. The best corrected visual acuity (BCVA), fluorescein angiography and optical coherence tomography (OCT) before and after surgery were compared. RESULTS: The mean preoperative BCVA (log MAR) were 0.79+/-0.29 and postoperative BCVA (log MAR) at 3 months was 0.57+/-0.33. And improvement of visual acuity > or =2 lines was observed in 10 eyes (45%). The mean preoperative fovea thickness measured by OCT was 595.22+/-76.83 micrometer (510-737 micrometer) and postoperative fovea thickness was 217.60+/-47.33 micrometer (164-285 micrometer). CONCLUSIONS: Vitrectomy with AV sheathotomy can be one treatment option for the patients with recurrent macular edema in BRVO.

A 58-year-old man admitted to our opthalmology department with the complaint of branch retinal vein occlusion. He was treated with intravitreal Ozurdex in the right eye. Two days after the injection, the patient presented with ocular pain and the visual acuity was hand movement. A diagnosis of endophthalmitis was made. We performed emergent pars plana vitrectomy (PPV) and the implant was removed from the vitreous cavity using a retinal forceps. A combination of vancomycin 1.0 mg and amikacin 0.4 mg was injected intravitreally. However, because of the blurring in the vitreus one week after the procedure, phacoemulsification and a repeat PPV was performed. Five days after the last procedure the signs and symptoms of endophthalmitis were resolved. Our case demonstrated that endophthalmitis could develop after intravitreal implantation of Ozurdex. Surgical removal of the implant and immediate vitrectomy seems to be a useful treatment option in these cases.
