目的：本實(shí)驗(yàn)的目的在于研究3個(gè)不同人種（白種人、黑人和亞洲人）后部脈絡(luò)膜厚度并探究三者之間的脈絡(luò)膜厚度是否存在差異,及其差異是否具有統(tǒng)計(jì)學(xué)意義。方法：此臨床實(shí)驗(yàn)為一項(xiàng)橫斷面觀察研究,收集了88例試驗(yàn)者這分成3個(gè)種群組別：白種人,黑人和亞洲人。實(shí)驗(yàn)設(shè)計(jì)參數(shù)包括臨床眼科學(xué)病史詢問、最佳矯正視力、屈光度、裂隙燈、眼壓、眼軸、眼底照相、血壓和快速血糖測(cè)定。脈絡(luò)膜的檢查通過SD-OCT的EDI技術(shù)完成。脈絡(luò)膜厚度的測(cè)量范圍為前界的視網(wǎng)膜色素上皮層至后界的脈絡(luò)膜鞏膜分界線,該兩條分界線均由手動(dòng)操作劃分。運(yùn)用SPSS軟件分析三組脈絡(luò)膜厚度數(shù)據(jù)并比較年齡、性別、屈光度和眼軸等相關(guān)因素的影響。結(jié)果：男性和女性的入組數(shù)相等,百分之五十（44只眼）為男性,女性相同。次試驗(yàn)受試者平均年齡為27.43±1歲。種族和平均年齡如下：白種人34.09%,26.58±1.4歲；黑人34.09%,26.90±2歲,黃種人31.81%,28.91±1.4歲。平均脈絡(luò)膜厚度分別為403.62±37.4um、372.47-31.4umm和383.64±40um。所有受試者的平均脈絡(luò)膜厚度為386.64±10.5umm。平均屈光...
