Pigmentary glaucoma
Glaucoma
Key Points
- •Pigmentary glaucoma affects young myopic males - classic triad: Krukenberg spindle, spoke-like iris transillumination defects, and dense homogeneous TM pigmentation
- •Reverse pupillary block (posterior iris bowing) causes mechanical rubbing of IPE against zonules → pigment dispersion → TM obstruction
- •Regression phase occurs after age 50 as lens thickening reduces iris-zonule contact - but permanent TM damage may sustain elevated IOP
- •Differentiate from pseudoexfoliation: PG has homogeneous TM pigment and radial iris transillumination vs PXF's patchy pigment and peripupillary transillumination
- •Vigorous exercise can trigger acute pigment showers and IOP spikes - counsel patients but do NOT prohibit exercise
