Hemorrhagic retinal infarction due to inadvertent overdose of cefuroxime in cases of complicated cataract surgery: retrospective case series.

Abstract

To present 4 patients that developed hemorrhagic retinal infarction attributable to inadvertent overdose of cefuroxime after cataract surgery. Case series. Surgery in 4 patients was complicated-the posterior capsule was absent or torn-and anterior vitrectomy was performed. Cefuroxime was inadvertently injected at a dose higher than recommended in all 4 cases. Case 1 had hemorrhage in the central and inferior retinal regions, as well as optic atrophy. Case 2 had hemorrhage in the peripapillary and macular regions, as well as optic atrophy. Case 3 had hemorrhage in the peripapillary and inferior retinal regions, as well as macular pucker attributable to fibrovascular formation in the central retinal region. Case 4 had hemorrhage in the peripapillary, macular, and inferior retinal regions. The cefuroxime doses administered to the presented patients were much higher than reported in other cases and resulted in a higher concentration in the vitreous. Consequently, the severity of toxicity was much higher than in other reported cases of cefuroxime-induced toxicity. In cases of intracameral cefuroxime overdose, hemorrhagic retinal infarction can develop after cataract surgery.
