A Case of Phacoanaphylactic Uveitis Presenting as Endophthalmitis

Purpose: To report a case of phacoanaphylactic uveitis presenting as endophthalmitis. Case summary: A 77-year-old woman presented with sudden visual disturbance and painful red right eye. She did not have a history of trauma or surgery in her right eye. Her best corrected visual acuity was hand movement in the right eye and log MAR 0.22 in the left eye; intraocular pressure was 27 mm Hg in the right eye and 15 mm Hg in the left eye. Slit-lamp examination revealed corneal edema and prominent inflammation with hypopyon in the anterior chamber. B-scan showed vitreous opacity behind the lens. Based on the diagnosis of endophthalmitis, anterior chamber paracentesis and irrigation were performed. After irrigation, a hypermature cataract with intact anterior capsule was observed. Therefore, we performed extracapsular cataract extraction and intravitreal antibiotics injection. Gram staining of the aqueous humor revealed numerous macrophages filled with lens protein but no organisms. She was treated with hourly topical corticosteroid and an antibiotic agent. One month later, the anterior chamber is clear, and the cultures remained negative. Conclusions: We report a case of spontaneous phacoanaphylactic uveitis presenting as endophthalmitis in a patient with no history of eye trauma or surgery. J Korean Ophthalmol Soc 2016;57(9):1480-1483
