목적 : We investigated the peripapillary choroidal thickness (CT) and flow voids in the choriocapillaris in eyes with nonexudative age-related macular degeneration (AMD) using optical coherence tomography (OCT) and OCT angiography (OCTA). 방법 : We retrospectively reviewed the medical records of patients with nonexudative AMD and classified their eyes into three categories: pachydrusen, drusen, and subretinal drusenoid deposit (SDD). Mean macular and peripapillary CT and choriocapillaris flow void area (%) were compared among the three groups. 결과 : The three groups included 29, 33, and 33 patients, respectively. The mean macular and peripapillary CT findings were 260.64 ± 75.85 μm and 134.47 ± 46.28 μm for the pachydrusen group; 163.63 ± 64.08 μm and 93.47 ± 39.07 μm for the drusen group; and 95.33 ± 28.87 μm and 56.06 ± 11.64 μm for the SDD group (all, P < 0.001). The mean peripapillary flow void area showed differences; SDD group (11.90 ± 2.14%), drusen group (9.00 ± 2.32%) and pachydrusen group (7.25 ± 1.98%) (P < 0.001). 결론 : The peripapillary CT and flow voids in the choriocapillaris varied according to the features of drusen in nonexudative AMD eyes. |
