Iridoschisis: à propos d’un cas
Abstract
Iridoschisis is a rare degenerative disease characterized by the cleavage of the iris stroma into two layers, the disintegration of the anterior layer into fibrils floating into the aqueous humor and the attachment of the posterior layer to the dilator muscle and to the retinal pigment epithelium. It preferentially affects elderly persons and is often complicated by closed-angle glaucoma, cataract and bullous keratopathy. The picture shows a 74-year-old patient who presented with decreased visual acuity. Ophthalmologic examination showed (A): corneal transparency, shallow anterior chamber, round and centered pupil, iris atrophy and stromal layer fragmentation greater on the left side with total white cataract in the left eye. Gonioscopy (B) objectified inconspicuous iridocorneal angle beneath obstructed by iris debris floating and narrow for the rest. UBM examination (QUE) showed cleavage of the iris into two layers. The patient underwent cataract surgery with significant improvement in visual acuity (D).
