| Popis: | To investigate changes in retinal vessel diameter and blood velocity in high myopia using laser Doppler velocimetry. Thirty-nine subjects (39 eyes) were enrolled in the study. The subjects were divided into three groups according to their refractive status; 15 eyes (15 patients) with emmetropia (within ±3.0 diopters), 14 eyes (14 patients) with mild myopia (between −3.0 and −8.0 diopters), and 10 eyes (10 patients) with high myopia (>−8.0 diopters). Patient age was matched between groups. Blood velocity and vessel diameter of the upper or lower temporal retinal artery were measured using laser Doppler velocimetry with an eye-tracking system, and measurements were compared between groups. The average retinal blood flow and vessel diameter in highly myopic eyes were significantly decreased compared with emmetropic eyes or mild myopic eyes (Mann-Whitney U test, p |
