Size of the neuroretinal rim and optic cup and their correlations with ocular and general parameters in adult Chinese: the Beijing eye study

Abstract

In adult Chinese, the neuroretinal rim area measures 1.70 (0.30) mm(2) on optic disc photographs. It is statistically independent of age. Compared with data from studies in Western countries, the neuroretinal rim is larger in adult Chinese than in adult white populations, corresponding to a larger optic disc size in the Chinese.
