摘要

An 18-day-old female infant with a diagnosis of incontinentia pigmenti, which had been confirmed by biopsy findings from a hyperpig-mented bullous skin rush on the anterior surface of both lower extremities (Fig. 1), was referred to our clinic for retinal evaluation. She weighed 3220 g at birth and had been born at 41 weeks gestation. Initial retinal examination with scleral depression of the right eye revealed a pale optic nerve, and markedly dilated and tortuous retinal vessels with an abrupt termination within the posterior pole, extending three disc areas temporally and inferiorly, two disc areas nasally and one disc area superiorly to the disc (Fig. 2A). The peripheral retina beyond the anastomotic ring was completely avascular. These findings resembled those of zone 1 aggressive posterior retinopathy of prematurity. Retinal examination of the left eye revealed a normal disc and macula with mild dilatation of the retinal veins at the posterior pole (Fig. 2B). These vessels terminated beyond the major vascular arcades. There appeared to be vascular anastomoses throughout 360 degof the retina. The peripheral retina was avascular and demonstrated an ischaemic appearance with haemorrhages. There was no evidence of retinal detachment in either eye.
