To determine the value of serial personal photographs in timing the onset of unilateral cataracts in children over 6 months of age.
Personal photographs from children with unilateral cataracts who underwent cataract extraction and intraocular lens implantation when > or =6 months of age were reviewed. Photographs were evaluated for changes in the red reflex, which might indicate the presence of a cataract.
Twelve children underwent cataract surgery at a mean age of 37 months. They were followed for a mean of 32 months. Ten children were diagnosed as having an acquired cataract by photographic review documenting a previously normal red reflex. The visual acuity in the affected eye of 4 of these children improved to > or =20/60. Cataracts were visible on photographs prior to clinical diagnosis in 6 patients, from 0.5 to 22 months prior to clinical diagnosis. Visual outcomes did not relate closely to the photographically documented duration of the cataract prior to treatment. Photographs were not helpful in timing the onset of cataract in 2 children due to the poor quality of the images.
Serial personal photographs are sometimes helpful in determining whether cataracts are acquired. However, the usefulness of personal photographs alone in predicting the visual outcome after cataract surgery was limited in this small, retrospective study.
确定系列个人照片对于判断6个月以上儿童单侧白内障发病时间的价值。
回顾6个月及以上接受白内障摘除和人工晶状体植入手术的单侧白内障患儿的个人照片。评估照片中红色反光的变化，其可能提示白内障的存在。
12名儿童平均在37个月时接受了白内障手术。他们平均随访32个月。通过照片回顾记录到先前红色反光正常，10名儿童被诊断为后天性白内障。其中4名儿童患眼视力提高到20/60及以上。6例患者在临床诊断前0.5至22个月的照片上可见白内障。视觉结果与治疗前照片记录的白内障持续时间没有密切关系。由于图像质量差，照片对2名儿童白内障发病时间的判断没有帮助。
系列个人照片有时有助于确定白内障是否为后天性。然而，在这项小型回顾性研究中，仅个人照片对预测白内障手术后视觉结果的作用有限。
