Atypical retinitis pigmentosa masquerading as a nerve fiber bundle lesion

Retinitis pigmentosa with concomitant essential iris atrophy and glaucoma - case report

Purpose

To report a case of a young patient with retinitis pigmentosa (RP), essential iris atrophy, and glaucoma.

Case report

This report presents a case of a 22-year-old female patient with unilateral glaucoma, increased intraocular pressure, increased cup–disc ratio, iris atrophy, peripheral anterior synechiae, and bilateral RP.

Discussion

The patient presented glaucoma due to the iridocorneal endothelial syndrome, despite low age. RP is a bilateral disorder that may be associated with angle-closure glaucoma.

Peripapillary (pericentral) pigmentary retinal degeneration

Three patients with peripapillary (pericentral) pigmentary retinal degeneration described in 1978 were examined over a follow-up period of nine to 13 years. There was no extension of the geographic pigmentary abnormalities. The affected areas worsened as evidenced by an increase in pigment abnormalities, focal choroidal atrophy as seen on fluorescein angiography, and a diminution of the electroretinographic responses. One patient had increasing disabling symptoms of nyctalopia and poor peripheral and central vision, whereas the other two patients remained asymptomatic with excellent central vision.
