목적 : To describe the clinical features of hemorrhagic complications secondary to optic disc drusen (ODD) using spectral-domain optical coherence tomography (SD-OCT).
방법 : Sixty-three consecutive patients with SD-OCT-documented ODD who presened at Seoul National University Bundang Hospital from December 2009 to July 2012 were included. Full ophthamologic examinations, including fundus photographs, SD-OCT, fundus angiography, and visual field tests were analyzed in a total of 101 ODD-positive eyes from 63 patients.
결과 : Hemorrhagic ODD complications were found in 7 eyes (7%) from a total of 101 eyes with ODD. All of them had buried ODD(visualized with SD-OCT) and myopia (mean spherical equivalent = −4.00 ± 2.35 diopters). Patients with ODD hemorrhagic complications had smaller disk diameters than patients without hemorrhagic complications (1,308 ± 166 vs.1,555 ± 217 mm, P = 0.004). Peripapillary hemorrhages were classified into the following 3 types based on SD-OCT findings: subretinal (6 eyes, 86%), retinal (5 eyes, 71%), and vitreous hemorrhage (4 eyes, 57%).
결론 : Peripapillary hemorrhage can often occur in patients with buried ODD and small disk diameters. As SD-OCT can be used to visualize ODD beneath hemorrhage, it is helpful with the differential diagnosis and follow-up evaluation.
