후부공막염으로 인한 이차성 폐쇄각에서 레이저홍채절개술 후 발생한 장액망막박리 1례

Abstract

This study was aimed to report a case of serous retinal detachment following laser peripheral iridotomy (LPI) for the treatment of angle closure secondary to posterior scleritis. A 55-year-old man with bilateral ocular pain, redness, and headache was referred to Keimyung University Dongsan Medical Center. At the initial examination, his visual acuity was 1.0 in the both eyes. The intraocular pressure (IOP) was 25mmHg in the right eye and 28 mmHg in the left eye. Slit lamp examination showed a shallow anterior chamber, which was found to be Shaffer grade I by gonioscopy. There were no specific findings in the fundus, except a slightly edematous disc margin in both eyes. LPI was performed on both eyes. Fourth day after LPI, the patient complained of a central scotoma and visual disturbance of the left eye, in which the visual acuity had decreased to 0.06. The optical coherence tomography showed serous retinal detachment at the posterior pole. Fluorescein angiography revealed a focal leakage in the superotemporal area, as well as multiple hyperfluorescence lesions. Posterior scleritis of the left eye was diagnosed. Systemic steroid therapy was initiated and the area with the leakage was treated by focal laser photocoagulation. Two weeks later, the serous retinal detachment of the left eye resolved and visual acuity improved to 0.63. Laser peripheral iridotomy can exacerbate serous retinal detachment in patients with posterior scleritis that presented as acute angle closure.
