Abstract BACKGROUND: Pigmentary Dispersion Glaucoma (PDG) is a condition that usually affects white males. Over 2.0 % of Caucasian men acquire this condition. Men are affected more often than women, myopes more often than hyperopes, the condition is usually lessened with the onset of presbyopia, and 50 % of all patients with Pigment Dispersion Syndrome develop open angle glaucoma at some point in time.

This secondary glaucoma results from the trabecular meshwork becoming blocked by pigment particles released from the iris and impeding the outflow of aqueous humor from the anterior chamber. This pigmented material, which is released from the iris pigment epithelium, may deposit throughout the anterior chamber, giving rise to signs such as Krukenberg’s spindles, pigment granules on the anterior lens, iris dusting, or mid-peripheral iris transillumination defects.

CASE REPORT(S): The case of a 54-year-old African-American male with Pigment Dispersion Syndrome, glaucoma, and diabetes is presented. While most patients with PDG are Caucasian, male, myopic, non-presbyopes, and have an average age of onset of 34 years old, this patient is African-American, a hyperope, a presbyope, and much more than the average age of onset for males. This patient’s intraocular pressure changed from 23/20, OD/OS respectively, predilation one week prior, to 36/26 post-dilation, with angles open per Van Herick. Differential diagnoses and management options are discussed. Differences in the signs found in various races are presented.

CONCLUSIONS: While PDG is quite rare in African-American patients, the prudent clinician should be aware of the possibility that these patients may have the condition and respond accordingly.
