PURPOSE
To report an unusual cause of decreased vision in an aphakic patient.
DESIGN
Interventional case report.
PARTICIPANT
One patient.
INTERVENTION
An 80-year-old woman presented with a myopic shift and decreased visual acuity in the left eye 16 years after extracapsular cataract extraction (ECCE) without intraocular lens (IOL) implantation. Slit-lamp examination after pupil dilation revealed a milky fluid accumulation between the posterior lens capsule and the anterior hyaloid membrane. A neodymium:yttrium-aluminium-garnet (Nd:YAG) laser hyaloidotomy was performed on the anterior hyaloid membrane.
MAIN OUTCOME MEASURES
Refraction and best-corrected visual acuity.
RESULTS
The Nd:YAG laser hyaloidotomy allowed the trapped fluid to flow into the vitreous cavity. The myopic shift disappeared immediately and visual acuity improved.
CONCLUSIONS
To our knowledge, this is the first report of a late-onset hyaloideocapsular block syndrome after ECCE without IOL implantation.
目的
报告一例无晶状体患者视力下降的罕见原因。
设计
介入性病例报告。
参与者
一名患者。
干预措施
一名80岁女性在白内障囊外摘除术（ECCE）后16年未植入人工晶状体（IOL），出现左眼近视性移位和视力下降。散瞳后裂隙灯检查发现晶状体后囊膜与前玻璃体膜之间有乳白色液体积聚。对前玻璃体膜进行了钕：钇铝石榴石（Nd:YAG）激光玻璃体膜切开术。
主要观察指标
验光和最佳矫正视力。
结果
Nd:YAG激光玻璃体膜切开术使被困液体流入玻璃体腔。近视性移位立即消失，视力提高。
结论
据我们所知，这是首例白内障囊外摘除术后未植入人工晶状体的迟发性玻璃体囊膜阻滞综合征报告。
