Abstract:
Objective To observe the characteristics of the choroidal circulation in the macular area in patients with high myopia. Methods Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 25 cases (44 eyes) with high myopia, 16 cases (20 eyes) of low to moderate myopia, and 19 cases (24 eyes) of normal eyes using TOPCON50IA fundus fluorescein photographic system. The filling time of fluorescence in the choroid at the earlier stage and the filling time of fluorescence in the choroidal vessels in each group were compared. The relationship of the abnormal fluorescence configuration and the blood perfusion in the choroidal capillary vessels with the corrected visual acuity was analyzed. Results The filling time of fluorescence in the choroid at the earlier stage in eyes with high myopia and the filling time of fluorescence in the choroid in the macular area were significantly different from those of the control ( P
