목적 : The purpose of this study was to compare the visual outcome after the incidence of submacular hemorrhage among different subtypes of age-related macular degeneration (AMD).
방법 : We retrospectively reviewed the medical records of 67 patients (67 eyes) who underwent treatment for submacular hemorrhage associated with AMD. All the patients underwent pneumatic displacement. Demographic parameters, visual acuity (VA), and anatomical features were analyzed among AMD subtypes: typical AMD, polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP).
결과 : Among the eyes with submacular hemorrhage, 24, 30, and 13 eyes had typical AMD, PCV, and RAP, respectively. Post-treatment best-corrected VA was best in the PCV group and worst in the RAP group (p < 0.001). The proportion of eyes with improved VA was highest in the PCV subtype and lowest in the RAP subtype (p = 0.044). Logistic regression analysis showed that AMD subtype (p = 0.016) and time to treatment (<7 days) (p = 0.037) are associated with the final visual outcome.
결론 : The final visual outcome after the incidence of submacular hemorrhage was best in the PCV group and worst in the RAP group. AMD subtype is a significant factor associated with the visual prognosis of submacular hemorrhage.
