PURPOSE
The study present the central retina arterial supply, optic disc shape, RNFL (retinal nerve fiber layers) thickness and optic disc rim area. METHODS: To evaluate the relationship between central retina artery pattern, optic disk shape, and RNFL thickness was measured using optical coherence tomography (OCT3000) and pattern of the central retinal artery were investigated by TRC50IX. Healthy Koreans (107 males, 97 females) were enrolled in this study. The classification is made by dividing surface of the nerve head into ten sector. RESULTS: As a result of the shape of the optic disc divided into four group, vertically oval were 54%. The results showed the central retinal artery, in 252 eyes, had its origin in the center. None of the eyes had their origin on temporal side. RNFL thickness according to OCT parameter was superior, 127.68+/-16.16 micrometer; temporal quadrants, 79.60+/-16.05 micrometer; inferior quadrants. CONCLUSIONS: In summary, this study indicates that in healthy Koreans the shape of the optic disc is vertically oval and the origin of their central retinal artery is at the center. The RFNL thickness of both the superior and inferior quadrants was 127 micrometer according to OCT. |
