To describe the occurrence of visual loss secondary to dispersion of cells deriving from an iris strand during pupil dilation in a 35-year-old woman.
A 35-year-old woman presented complaining of blurring in the Left Eye 15-30 minutes following breastfeeding at night hours. On clinical examination, the uncorrected visual acuity was 20/20 in both eyes and slit-lamp examination demonstrated cells in the anterior chamber (26-50 cells in field/3+ SUN working group grading) whereas the examination of the right eye was unremarkable. Dilated examination revealed a thin pigmented strand of iris in the Left Eye spanning from one edge of the iris to the other (1st to 8th h). This strand was connected at a single point to the anterior capsule of the lens and from the point of connection red blood cells flowed in a linear configuration that ended at the lower part of the anterior chamber.
In this case report a patient with persistent pupillary membrane in the form of an individual iris strand connected to the anterior lens capsule presented with episodes of monocular vision loss. This occurred due to red blood cell dispersion from the iris strand during mesopic light conditions and pupil dilation while breastfeeding. To the best of our knowledge, this is the first report in the literature.
描述一名35岁女性在瞳孔扩张期间，因源自虹膜条索的细胞分散而继发视力丧失的情况。
一名35岁女性主诉夜间哺乳后15 - 30分钟左眼视物模糊。临床检查时，双眼未矫正视力均为20/20，裂隙灯检查显示前房有细胞（每视野26 - 50个细胞/ SUN工作组3 +级），而右眼检查无异常。散瞳检查发现左眼有一条细的色素性虹膜条索，从虹膜的一侧边缘延伸至另一侧（1点至8点）。这条条索在单个点与晶状体前囊相连，红细胞从连接点呈线性流动，终止于前房下部。
在本病例报告中，一名以连接晶状体前囊的单个虹膜条索形式存在持续性瞳孔膜的患者出现单眼视力丧失发作。这是由于在中度暗光条件下以及哺乳时瞳孔扩张期间，红细胞从虹膜条索分散所致。据我们所知，这是文献中的首例报告。
