摘要: PURPOSE To characterize the mean topographical shape of human sclera a normal eye. METHODS Forty-five participants aged from 19 to 45 years and with no previous ocular surgeries were included in this study. Four three-dimensional (3D) corneo-scleral maps both eyes acquired using topographer (Eye Surface Profiler). For each 3D map, (maximum diameter 16 mm) cornea automatically separated at level limbus. The remaining scleral ring was further fit quadratic function. elevation difference between original data calculated. statistical analysis, divided into eight sectors: nasal, temporal, superior, inferior, supero-nasal, supero-temporal, inferior-nasal inferior-temporal. In addition, as inner (inner 6-7-mm radius) outer (external 7-8-mm radius). RESULTS Horizontally, nasal area showed less [mean (SD) -30 (52) μm (OD)] than temporal 4 (47) (OD)], p < 0.001. Vertically, inferior 32 (72) slightly elevated superior (mean 36 (84) μm, but not statistically significant (p = 0.40). Besides, asymmetry found increase radial distance corneal apex. No right left CONCLUSION Human is rotationally asymmetric, its varies considerably subjects.
