A 76-year-old male diagnosed with open-angle glaucoma since 8 years presented with reduced vision in the right eye. Slit-lamp examination revealed an irregularly shallow anterior chamber, peaked pupil inferotemporally in the right [Figure 1]a, and inferonasally in the left eye [Figure 1]b. There were scattered peripheral anterior synechiae (PAS) with diffuse iris stromal atrophy [Figure 2], which was more prominent inferiorly. Both eyes had irregularly scattered synechial angle closure on gonioscopy [Figure 3] with advanced glaucomatous disc damage. | Figure 1: Slit-lamp picture of the right eye (a) represents scattered iris stromal splitting (black arrows denoting) with peaked pupil at 8 o'clock, left eye (b) reflects the same features (white arrow indicates the pupil peaking inferonasally)

| Discussion | |  |
Iridoschisis, a rare form of secondary angle-closure glaucoma, usually presents as bilateral, progressive diffuse stromal splitting (or schisis), which differentiates this from primary glaucoma.[1],[2],[3] This should not be confused with other causes such as essential iris atrophy with ischemia and developmental glaucoma such as iridocorneal endothelial syndrome.[4] Management of progressive angle closure and cornea change. Progressive synechial angle closure and corneal bullae may occur by direct contact with iris strands.
