[Early postcontusion eyeball circulation as evidenced by color Doppler mapping].
Early postcontusion hemodynamic disorders were studied, by analyzing the results of color Doppler mapping. The study included patients aged 10 to 45 years with moderate and severe postcontusion retinal changes and a visual acuity of 0.8 to 0.01. Color Doppler mapping was used to visualize blood flow in the ophthalmic artery, central retinal artery, and posterior short ciliary arteries. Preliminary studies revealed circulatory changes in the ophthalmic arterial system in the early postcontusion period. In severe macular and optic nerve lesions, a significant reduction in blood flow was detectable in all the vessels under study, but there was its more pronounced reduction in the central retinal artery and posterior short ciliary arteries, which directly corrected with the found retinal changes since these arteries are the only source of retinal circulation.
