Abstract
Background
Angle-closure glaucoma in children at the cicatricial stage of retinopathy of prematurity (ROP) has been thought to be caused by the anterior displacement of the lens–iris diaphragm resulting from contraction of a retrolental fibrous membrane. Other possible mechanisms include pupillary block and ciliary block.
Cases
Three patients (three eyes) at the cicatricial stage of ROP with angle-closure glaucoma were examined by high-resolution ultrasonography before and after peripheral iridectomy.
Observations
High-resolution ultrasonography preoperatively showed that the angle was closed. A retrolental fibrous membrane was attached behind the lens. After the iridectomy, ultrasonography showed an open angle, and the intraocular pressure was normal.
Conclusions
The angle closure in our three patients was caused mainly by a pupillary block and could be treated by peripheral iridectomy. Jpn J Ophthalmol 2005;49:312–314 © Japanese Ophthalmological Society 2005
