To evaluate which factor(s) might predict excellent Snellen visual acuity results in unilateral nontraumatic pediatric aphakes.
Retrospective review of all unilateral pediatric aphakic patients seen in a specialty contact lens clinic between 1982 and 2009. Inclusion criteria as follows: (1) cataract extraction before age 6 weeks, (2) no other health complications, (3) contact lens fitting within 3 weeks postsurgery, and (4) measurable subjective visual performance on a clinical Snellen acuity chart. Fifteen patients were identified: 10 patients with persistent fetal vasculature syndrome (PFV) and 5 patients with the diagnosis of idiopathic congenital cataract (ICC).
Final Snellen acuity results showed seven patients (46.67%) developed excellent Snellen visual acuities (defined as 20/50 or better), four patients (26.67%) developed moderate Snellen visual acuities (20/125 to 20/60), and four total patients (26.67%) developed poor Snellen visual acuities (worse than 20/200). Analysis used descriptive statistics.
Approximately 50% of our unilateral nontraumatic pediatric aphakic patients aged older than 5 years achieved excellent Snellen visual acuity in the aphakic eye. The amount of surgical or ocular complications seems to have an inverse relationship with Snellen visual acuity in PFV. Patching compliance, without implying cause-effect direction, also had a direct relationship with final Snellen visual acuity for patients. Early cataract extraction, good to moderate patching compliance, and aggressive early contact lens management can lead to moderate to excellent Snellen visual results in several unilateral pediatric aphakic patients.
评估哪些因素可能预测单侧非外伤性儿童白内障患者的 Snellen 视力结果优秀。
回顾性分析 1982 年至 2009 年间在一家专业隐形眼镜诊所就诊的所有单侧儿童白内障患者。纳入标准如下：（1）6 周龄前白内障摘除，（2）无其他健康并发症，（3）术后 3 周内配接触镜，（4）可在临床 Snellen 视力表上测量主观视觉表现。共确定了 15 名患者：10 名永存胎儿血管综合征（PFV）患者和 5 名特发性先天性白内障（ICC）患者。
最终 Snellen 视力结果显示，7 名患者（46.67%）获得了优秀的 Snellen 视力（定义为 20/50 或更好），4 名患者（26.67%）获得了中等 Snellen 视力（20/125 至 20/60），4 名患者（26.67%）获得了较差的 Snellen 视力（20/200 或更差）。分析采用描述性统计。
我们的单侧非外伤性儿童白内障患者中，年龄大于 5 岁的患者中约有 50%在无晶状体眼中获得了优秀的 Snellen 视力。手术或眼部并发症的数量似乎与 PFV 的 Snellen 视力呈反比关系。不暗示因果关系的遮盖依从性也与患者的最终 Snellen 视力呈直接关系。早期白内障摘除、良好至中度遮盖依从性和积极的早期接触镜管理可使数名单侧儿童白内障患者获得中等至优秀的 Snellen 视力结果。
