| 摘要 目的：分析2009例藏族白内障手术患者的病因构成及相关因素。方法：收集2013年10月至2014年10月西藏自治区藏医院眼科2009例藏族白内障手术患者病例资料，按病因、年龄、性别、白内障类型、人工晶状体屈光度、文化程度、经济水平进行分类，运用统计学方法分析西藏地区藏族白内障患者发病特点。结果：2009例藏族白内障手术患者中，年龄相关性白内障1885眼(93.83%)，核性白内障1197例(59.58%)。年龄2-89岁，平均年龄62.53岁，男1012眼(50.37%)，女997眼(49.63%)。50-59岁年龄组的核性白内障患者比例明显高于40-49岁年龄组(P＜0.01；80-89岁年龄组的核性白内障患者比例高于70-79岁年龄组(P＜0.05)。根究Emery分级，50-59岁年龄组Ⅳ级白内障患者比例明显高于40-49岁年龄组(P＜0.01)；80-89岁年龄组Ⅳ级白内障患者比例明显高于70-79岁年龄组(P＜0.05)。术前裸眼视力为0.02及0.02以下1688例(84.02%)。高度近视患者13例(0.65%)，远视患者406例(20.21%)。农牧区患者1310例(65.21%)，明显多于其他行业患者。结论：年龄相关性白内障仍是西藏地区藏族白内障患者的主要病因，以核性白内障为主要发病类型。随年龄增长，核性白内障患者越来越多，核硬度分级越来越高。患者主要来源于农牧区，多数术前视力差。高度近视发病率较其他地区发病率低，而远视发病率较高。 |

| ABSTRACT Objective: To analyze the constituent of etiological factor and relevant factors (age, profession, economic, diopter and so on) in 2009 cases of Tibetan patients with cataract. Methods: This study was conducted in Tibetan Medical Hospital and 2009 cases of Tibetan patients administrated with non-phacoemulsification cataract surgery were collected from October 2013 to October 2014. The Clinical data were classified according to etiology, age, gender, type of cataract, intraocular lens power, educational level and economic level. The statistical methods were employed to analysis the clinical characteristics in these patients. Results: This study enrolled 2009 patients including 997 females and 1012 males with a mean age of 62.58± 13.18 years old. There were 1197(59.58%) patients with nuclear cataract and 1885 (93.83%) with age-related cataract. The proportion of nuclear cataract patients at age of 50-59 years old was significantly higher than those at age of 40-49 years old (P <0.01). The proportion of nuclear cataract patients at age of 80-89 years old is higher than those at age of 70-79 years old (P <0.05). According to the Emery Classification，the proportion of Grade Ⅳ cataract patients at age of 50-59 years old was significantly higher than those at age of 40-49 years old (P <0.01); and the proportion of Grade Ⅳ cataract patients at age of 80-89 years old was significantly higher than those at age of 70-79 years old (P <0.05). The patients with preoperative uncorrected visual acuity less than 0.02 accounted for 84.02% (1688 eyes). Furthermore，The number of the patients with high myopia and hyperopia are 13(0.65%) and 406 (20.21%), respectively. Patient number from agricultural and pastoral (65.21%) was significantly more than that from other industry area (34.78%). Conclusion: Age-related cataract is still the main cause of Tibet Tibetan cataract patients and nuclear cataract accounts for the majority. With the age increasing, the ratio of patients with nuclear cataract became higher, and the Emery nuclear grade became larger. Patients mainly from the agricultural and pastoral areas had poor preoperative visual acuity. The incidence of high myopia in Tibet was lower than other regions in China. Contrarily, the incidence of myopia was relatively higher. |
