Case Report: Subconjunctival Bevacizumab for the Treatment of Refractory Pseudophakic Cystoid Macular Edema.

Significance In this report, the authors present a case of a 63-year-old man with recurrent pseudophakic cystoid macular edema. Macular edema was refractory to the treatments with periocular corticosteroid injection and topical anti-inflammatory medications. It was treated with subconjunctival bevacizumab (2.5 mg) injections. Purpose The purpose of this report was to demonstrate the efficacy and safety of repeated injections of subconjunctival bevacizumab in pseudophakic cystoid macular edema. Case report A 63-year-old White man presented with ongoing blurred vision in his left eye 4 months after a complicated cataract surgery. Despite the administration of sub-Tenon triamcinolone in the first-month visit because of cystoid macular edema and the use of topical steroid and nonsteroidal anti-inflammatory medications during the 4 months, there was no change in his vision. The first subconjunctival bevacizumab injection was performed 16 weeks after cataract surgery. The best-corrected visual acuity was significantly improved, and central retinal thickness dramatically decreased after the first injection. Macular edema reoccurred 26 and 46 weeks after cataract surgery. At these relapses, repeated subconjunctival injections of bevacizumab were influential in resolving macular edema and restoration of vision, even in the chronic phase. After 6 months, visual acuity (20/20) and central retinal thickness (274 μm) were stable after four total injections. No drug-related adverse events were observed during the follow-up period. Conclusions The repeated subconjunctival injections of bevacizumab were effective and well tolerated in pseudophakic cystoid macular edema. Subconjunctival bevacizumab may be a safe alternative to intravitreal applications in patients with pseudophakic cystoid macular edema.
