Abstract

Purpose: To compare the risks and benefits of adding either intravitreal dexamethasone implant (DEX) or preservative-free triamcinolone acetonide (TA) to bevacizumab monotherapy in refractory cystoid macular edema due to retinal vein occlusion. Methods: This is a multicenter, comparative, interventional, retrospective study that included 74 patients who were initially treated with intravitreal bevacizumab and later received either DEX or TA for the treatment of recalcitrant cystoid macular edema due to retinal vein occlusion. Main outcomes were best-corrected visual acuity, central macular thickness, cost of therapy, frequency of intravitreal injections, and side effects. Results: Thirty-nine patients received TA and 35 patients received DEX injections. Groups were similar in age and gender distribution. Although the mean central macular thickness improved significantly for all groups (P , 0.0001), logMAR best-corrected visual acuity did not change significantly after steroid introduction (P = 0.06). Frequency of any intravitreal injection decreased significantly from 0.66 ± 0.18 to 0.26 ± 0.08 injections per month after initiation of steroids (P , 0.0001). This effect was greater in the DEX groups (P , 0.0001). Monthly cost decreased with TA but increased with DEX. Conclusion: Adding steroids improved anatomical outcome but did not affect final vision. Injection frequency decreased significantly after adding steroids, more so with DEX. There was no difference between TA and DEX regarding anatomical or functional outcomes or the incidence of side effects.
