| 中文描述 | 瞳孔膜在胎兒時會關閉瞳孔，並通常會在出生前被吸收。若是再吸收不完全，可能會接觸角膜內皮留下疤痕或色素沉澱，造成先天的角膜不透明。視力通常是正常的。也可能接觸到水晶體造成先天性的白內障。 |
| 英文描述 | The pupillary membrane closes the pupil in the fetus, and is normally resorbed before birth. Incomplete resorption may allow strands to contact the corneal endothelium resulting in scarring or pigmentation, causing congenital corneal opacities. Vision is usually normal. May also attach to the lens to cause congenital cataracts. |
