Abstract
<div class="ftSection"><span class="ftInlineSubsectionTitle">BACKGROUND AND OBJECTIVE:</span><p> To determine the efficacy of intravitreal triamcinolone acetonide (IVTA) in the early treatment of severe cystoid macular edema (CME) related to acute branch retinal vein occlusion.</p></div><div class="ftSection"><span class="ftInlineSubsectionTitle">PATIENTS AND METHODS:</span><p> Retrospective, non-comparative case series. Twelve eyes with severe CME (foveal thickness &gt; 450 μm) secondary to acute branch retinal vein occlusion received IVTA.</p></div><div class="ftSection"><span class="ftInlineSubsectionTitle">RESULTS:</span><p>Average follow-up was 15.3 months. Mean visual acuity was 0.88 LogMar units (20/160) initially, 0.55 LogMar units (20/70) at 1 week, 0.46 LogMar units (20/60) at 1 month, and 0.49 LogMar units (20/60) at last follow-up. Visual acuity improved by 3 lines or greater in 42% of patients at 1 week, 50% at 1 month, and 42% at last follow-up. Average foveal thickness was 589 μm (range, 460 to 840 μm) at baseline, 237 μm at 1 week, 196 μm at 1 month, and 235 μm at last follow-up. All eyes showed reduction of foveal thickness as measured by optical coherence tomography. Eight eyes developed recurrent CME at an average of 5.5 months after initial IVTA injection. Ten eyes required additional intervention during the follow-up period.</p></div><div class="ftSection"><span class="ftInlineSubsectionTitle">CONCLUSIONS:</span><p>Early treatment of severe CME secondary to branch retinal vein occlusion with IVTA is effective in reducing foveal thickness as measured by optical coherence tomography and improving visual acuity. However, monotherapy with IVTA can be associated with a significant rate of recurrent CME.</p><p><b>[Ophthalmic Surg Lasers Imaging 2005;36:30–36.]</b></p></div>
