Question: What is pigment dispersion glaucoma?
Answer: Pigment dispersion (also called PDS or pigment dispersion syndrome) is a type of glaucoma that can occur in myopic (near sighted) eyes. The iris bows backwards and the back surface can rub on the underlying lens and zonules. Pigment from the back surface is rubbed off and can clog up the trabecular meshwork.
This can be picked up on a slit-lamp exam: you may see a kruckenberg spindle (vertical area of pigment stuck on the inner cornea), transillumination defects in the iris, and a highly pigmented trabecular meshwork on gonioscopy.

Good morning, my daughter age 49 has had PDS for 9 years,she was concerned at the time about her youngest son now 20, as he has been diabetic since 1998, age then 8.Diabetics are checked for glaucoma, but due his age that has been not the case, also she was told at the time it was not heredity, but extremely a rare complaint. She is now going to have her other children checked, as due to an eye injury it has been found that her 20 year old son has the complaint. Please forward all the information you can relating to PDS. thank you Anita, I am also concerned for the rest of my grandchildren and great grandchildren.
