中文摘要 | 背景:找出臺灣南部地區特有之近視並合併白內障患者之病因及型態特徵。 方法:共有332位接受過白內障摘除手術之患者(計440隻眼睛)的病歷被分析,其中163位(220隻眼睛)為早發型白內障,另169位(220隻眼睛)為老年型白內障患者。這二個族群分別再區分為不明原因、糖尿病、及高度近視相關之三類。年齡、性別、其他眼病、全身性疾病、及白內障型態皆予以記錄並運用X2 test分析。 結果:平均年齡方面,早發型為45.5±7.6歲,老年型則為68.7±8.0歲。在早發型患者中高度近視之比例較老年型患者有意義的偏高。在白內障型態方面,早發型患者間,高度近視族群以核硬化型為主,不明原因及糖尿病族群以後囊下混濁型為主。 結論:在南臺灣特有之近視地區,早發型白內障患者高度近視之比例較老年型患者為高而且主要以核硬化型態為主。 |
英文摘要 | Background: To determine the etiology and morphological features of cataracts in a myopia-endemic area of Taiwan. Methods: This retrospective case-controlled study comprised 332 patients (440 eyes) who underwent cataract-extraction surgery, 163 patients (220 eyes) constituting the presenile cataract study group, and 169 patients (220 eyes) constituting the senile cataract control group. Each group was divided into idiopathic, diabetic, and highly myopic subgroups. Age, gender, ocular and systemic comorbidities, and the types of cataract featured were recorded and analyzed. For the statistical analysis, 2 test was used. Results: The mean ages of study subjects were 45.5 ± 7.6 years for the presenile and 68.7 ± 8.0 years for the senile cataract groups. We also observed a greater number of cataracts in highly myopic eyes of the presenile group (17.27%) compared to the senile group (0.90%) ( p < 0.0001). The distribution of cataract types for the 3 presenile cataract subgroups revealed that nuclear sclerosis contributed most to presenile cataracts in highly myopic patients ( p = 0.001), and correspondingly, the posterior subcapsular opacity contributed most in the idiopathic and diabetic cataract subgroups ( p = 0.001). Conclusions: We observed a greater number of cataracts from highly myopic eyes in the presenile group than in the senile group in southern Taiwan, a myopia-endemic area. Nuclear sclerosis contributed most to the presenile cataracts in the highly myopic subgroup. |
