Common in young myopic males Raised IOP, mild-peripheral iris pigment atrophy and dispersion of pigments on the comeal endothelium in a vertical spindle pattern Krukenberg Spindle, trabecular mesh work, Schwalbes line, iris surface and lens equator characterize the pigmentary glaucoma. Gonioscopy shows pigment accumulation along the Schwalbes line especially inferiorly Sampaolesis line. Iris transillumination shows radial slit like transillumination defects in the mid periphery Pathognomic features.
