[Efficacy of direct revascularization of choroid in the treatment of atherosclerotic macular dystrophies].

The operation of direct revascularization of the choroid in atherosclerotic maculodystrophy was modified. The method of choroid revascularization is based on the formation of numerous anastomoses with vessels from the basin of the external carotid artery and with various branches of the orbital artery. The authors analyze the results of vascularization in 21 patients (27 eyes) aged 60 to 75 with atherosclerotic maculodystrophy. Vision acuity improved by 0.06 diopters on average in 80% of patients, the difference being statistically reliable (p < 0.05). The peripheral visual field (the sum of grades for 8 meridians) extended by 97% on average in 96% of patients. The index of the critical frequency of fusion of flashes increased directly after treatment by 4 Hz on average, which is 13% of the initial level (p < 0.05). The rheographic coefficient increased by 35% of the initial level. Hence, revascularization is an effective method for the treatment of atherosclerotic maculodystrophies, stabilizing the visual functions, and is recommended for clinical use.
