Pediatric cataracts constitute an important cause of low visual acuity.
The objective of the present work is to know the characteristics of this pathology in an ophthalmic attention unit of a developing country.
A retrospective, descriptive, transversal study was carried out in 328 cases of pediatric cataracts (children between 0 and 14 years).
190 (57.9%) patients were male and 138 (42.1%) female, 145 (44.2%) cases were congenital cataracts and 183 (55.8%) acquired cataracts; 160 (48.8%) presented unilateral affection and 168 (51.2%) bilateral. The treatment was surgical in 98.2% of the cases. The mean age at diagnosis of congenital cataract was 34.9 months. The mean age of presentation of the acquired ones was 76.6 months. The treatment was abandoned in 70.58% cases of congenital cataracts and 64.10% of acquired cataracts. In the congenital ones, 44% presented visual acuity in the range of 20/200 and 20/70 and in the acquired ones, 32.5% were better than 20/30.
The data found was not encouraging due to the late detection and the abandon of the treatment, which are bad prognosis factors.
小儿白内障是导致视力低下的一个重要原因。
本研究旨在了解一个发展中国家眼科诊疗机构中这种疾病的特点。
对328例小儿白内障患者（0至14岁儿童）进行了一项回顾性、描述性横断面研究。
190例（57.9%）患者为男性，138例（42.1%）为女性，145例（44.2%）为先天性白内障，183例（55.8%）为后天性白内障；160例（48.8%）为单眼患病，168例（51.2%）为双眼患病。98.2%的病例接受了手术治疗。先天性白内障的平均诊断年龄为34.9个月。后天性白内障的平均发病年龄为76.6个月。70.58%的先天性白内障病例和64.10%的后天性白内障病例放弃了治疗。先天性白内障患者中，44%的视力在20/200至20/70之间，后天性白内障患者中，32.5%的视力优于20/30。
由于发现较晚和放弃治疗，所获得的数据并不乐观，而这两个因素都是预后不良的因素。
