무증상안의 형광안저촬영에서 관찰되는 주변부망막의 혈관성 형광누출

초록

Purpose: To report peripheral vascular retinal leakage findings of asymptomatic eyes based on fluorescein angiography, and investigatethe associated factors. Methods: Data were collected retrospectively from 47 subjects (94 eyes) and the peripheral leakage results based on fluoresceinangiography were analyzed. The relationship between peripheral leakage findings and other factors including- arm-retinal circulationtime (ARCT) and venous filling time (VFT), refractive error, age, hypertension, and diabetes- was evaluated. Results: Ten eyes had peripheral leakage (21.3%). The mean age was 34.7 ± 7.86 years in the non-leakage group and 44.3 ±9.63 years in the leakage group; the difference between the groups was statistically significant (p = 0.001). The mean sphericalequivalent was -2.85 ± 2.71 diopter in the non-leakage group and -3.46 ± 3.62 diopter in the leakage group; the difference betweenthe groups were not significant (p = 0.471). The mean ARCT was 10.50 ± 2.06 seconds in the non-leakage group and11.76 ± 2.47 seconds in the leakage group; the difference between the groups was statistically significant (p = 0.041). The meanVFT was 9.70 ± 1.91 seconds in the non-leakage group and 10.75 ± 1.40 seconds in the leakage group; the difference betweenthe groups was statistically significant (p = 0.048). Conclusions: Peripheral leakage can be found in asymptomatic eyes. Age, VFT, and ARCT were correlated to peripheral leakagefindings based on angiography. These leakage findings were thought to be related with histological properties and physiologicalchanges in peripheral retina.
