目的：探讨青年离散核硬化症的临床特点。方法：回顾分析1所医院收治的45岁以下的核硬化症患者的白内障手术资料。排除先天性白内障、眼外伤、近视眼病和伴有白内障的全身性疾病患者。记录患者的年龄、性别、双眼晶状体状态、眼轴长度、术前、术前屈光状态、术前术后最佳矫正视力。结果：35例55眼，年龄32~45岁，符合研究标准。核硬化性白内障20例为双眼。平均手术年龄为40.64岁+/-3.63岁(SD)。术前平均屈光度为-7.80+/-3.57 D，术前平均屈光度为-17.40±-6.05 D，眼轴平均28.09±-2.31 mm。术后BCVA>20/22者53眼(96.4%)。在台湾年龄在45岁以下的白内障患者中，核硬化症并不是罕见的视力丧失原因，轴性近视与核硬化症的形成密切相关。多见双侧硬化症。眼轴长度大于27.0 mm的患者风险最大。手术治疗是有治疗作用的。(C)2003年《儿童权利公约》和《经济、社会和文化权利公约》。
Purpose: To document the clinical features of discrete nuclear sclerosis in young patients.Setting. Chang-Gung Memorial Hospital, Taoyuan, Taiwan, Republic of China.Methods: The medical records of all patients younger than 45 years with nuclear sclerosis who had cataract surgery at 1 hospital were retrospectively reviewed. Patients with congenital cataract, ocular trauma, ocular disease in addition to myopia, and systemic disease associated with cataract were excluded. The patients' age, sex, bilateral lens status, axial length, original and preoperative refractive status, and preoperative and postoperative best corrected visual acuities (BCVAs) were recorded.Results: Fifty-five eyes of 35 patients aged 32 to 45 years met the study criteria. Nuclear sclerotic cataract was bilateral in 20 patients. The mean age at surgery was 40.64 years +/- 3.63 (SD). The mean refraction before the development of cataract was -7.80 +/- 3.57 diopters (D) and the mean preoperative refraction, -17.40 +/-6.05 D. The mean axial length was 28.09 +/- 2.31 mm. The postoperative BCVA was 20/22 or better in 53 eyes (96.4%).Conclusions. In patients younger than 45 years with cataract in Taiwan, nuclear sclerosis was not a rare cause of visual loss and axial myopia was strongly associated with the formation of nuclear sclerosis. Bilateral sclerosis was observed in most cases. Patients with an axial length greater than 27.0 mm had the greatest risk. Surgical treatment was therapeutic. (C) 2003 ASCRS and ESCRS.
