马来西亚人视盘面积的研究(英文)

Optic disc area in Malaysian population

目的:评估马来西亚主要的三个种族群(马来人,中国人和印度人)的视盘参数,并且研究视盘参数和性别、眼内压、眼轴长度之间的关系。方法:本研究包括了122例244眼,均有清晰的眼介质,其中61例为开角型青光眼患者,另外61例为非青光眼个体。使用蔡司FF450Plus眼底照相机对视盘参数和视盘面积进行放大校正测量。三个种族群之间的差异用方差分析检验,而诸如性别、眼内压、眼轴长度这些因素和视盘大小之间的关系通过皮尔森双变量相关分析检验。结果:总体上平均垂直视盘直径为(1.96±0.20)mm,水平视盘直径为(1.84±0.20)mm,视盘面积为(2.84±0.56)mm2。与马来人和中国人相比,印度人有较大的视盘面积。然而,差异没有统计学意义。结论:马来西亚人的视盘面积比高加索人(白种人)大。在马来西亚三个种族群中,印度人视盘面积最大,但是没有统计学意义。

AIM： To evaluate the optic disc parameters in the three main ethnic groups of Malaysia （Malay, Chinese and Indian ）. Possible relationships between optic disc parameters and gender, intraocular pressure and axial length of eye were also studied. METHODS. The study included 244 eyes of 122 subjects （61 cases with open angle glaucoma and 61 nonglaucomatous individuals） with clear ocular media. Magnification corrected measurements of optic disc diameters and area were done using Zeiss FF450 Plus fundus camera. Differences between the three ethnic groups were tested by using ANOVA. The association between factors such as gender, intraocular pressure and axial length of the eye, and the optic disc size was tested throqgh Pearson~ bivariate correlation analysis. RESULTS; The overall mean vertical optic disc diameter was （1.96 ± 0.20） m m, horizontal optic disc diameter was （1.84±0.20）mm and optic disc area was （2.84 ±0.56）mm^2. Indians had larger optic disc area compared to Malay and Chinese. However, the difference was not statistically significant. CONCLUSION： Optic disc size is larger in Malaysian population than Caucasians. Among the three ethnic groups, Indians have the largest optic disc size without any statistical difference.
