N2 - Background: Limited data have evaluated multiple injections of the dexamethasone 700 mg implant (DEX) (Ozurdex; Allergan, Inc.) for cystoid macular edema (CME) secondary to retinal vein occlusion (RVO) over an extended regimen. Methods: This retrospective study evaluated patients treated with DEX for CME associated with RVO. Each patient had ophthalmologic evaluation, optical coherence tomography (OCT), and 4 weeks to 6 weeks follow-up intervals. Retreatment criterion was fluid on OCT. Outcome measures included best-corrected visual acuity, intraocular pressure (IOP), central macular thickness on OCT, fluid resolution on OCT, and required treatment for elevated IOP and cataract. Results: Thirty-one patients had 82 DEX injections, with 19 patients having ≥2, 12 having ≥3, 10 having ≥4, 6 having ≥5, and 4 having ≥6 DEX injections. All patients were followed at least 12 weeks and had a mean follow-up period of 344.94 days. Fourteen patients (45%) developed ocular hypertension (≥22 mmHg), and 40% of phakic patients required cataract surgery. Mean interval of OCT fluid resolution was 52 days (range, 28- 245; SD, ±8), and mean retreatment interval was 119 days (range, 42-309; SD, ±9). No patients required glaucoma surgery or developed endophthalmitis. Conclusion: This study suggests that repeated, as needed, DEX injections for CME associated with RVO may be performed. Patients should be monitored and treated for ocular hypertension and cataract progression.
