Abstract Purpose:To report a case of central retinal vein occlusion(CRVO)with recurrent intraocular inflammation after intravitreal aflibercept injection(IVA).

Case:An 83-year-old woman was referred to our hospital due to a recurrence of macular edema secondary to CRVO. Her medical history included diabetes mellitus for 30 years and polymyalgia rheumatica(on prednisolone). She had received a sub-Tenon triamcinolone acetonide injection twice and IVA three times in her left eye at a previous clinic. The best corrected visual acuity(BCVA)was 0.2 in the left eye, and macular edema with serous retinal detachment and retinal hemorrhage was observed. IVA was adminstered in our hospital, and 5 days after the 10th IVA, the BCVA was 0.02, and fine keratic precipitate, vitreous opacity, and vitreal opacity were observed in the left eye. Suspecting infectious endophthalmitis, a vitrectomy was performed on the same day, and antibiotic eye drops and intravenous administration of the antibiotics were initiated. Vitreous culture examination was negative for infection. Three months later, the macular edema recurred and another IVA was performed. Two days later, the same inflammatory findings were observed. Hence, the same treatment was performed as before. Thereafter, the intraocular inflammation quickly disappeared. The BCVA improved to 0.1 after three months the vitrectomy.

Conclusion:We report a case of recurrent endophthalmitis after IVA. Since vitreous culture examination was negative for infection at both times, it was assumed that some autoimmune mechanism related to aflibercept was involved in the etiology.
