What causes corneal pigmentation?
Corneal pigmentation (CP) can occur from mechanical damage, secondary exposure of the cornea (eg, lagophthalmos), or immune-mediated disease. Information in a CERF report indicated that 21.26% of pugs that underwent CERF ophthalmic examinations had exposure keratopathy syndrome and pigmentary keratitis.
How is pigment dispersion syndrome treated?
Pigment-dispersion syndrome can be treated with eye drops or other medications. In some cases, laser surgery may be performed.
What is corneal endothelial pigmentation?
Abstract. Multicolored corneal endothelial pigment was noted in patients on routine specular microscopy, confirming the presence of chromatic pigment deposits at the corneal endothelium. These deposits were polychromic, exhibiting blue, green, red, pink, orange, gold, and yellow colors.
What are the symptoms of pigment dispersion syndrome?
Pigment dispersion syndrome is more common in young, Caucasian, male patients who are near-sighted. The eye pressure can significantly increase during exercise, but usually returns to normal. These eye pressure spikes may cause symptoms such as blurry vision and rainbow colored haloes around lights.
How can I reduce my eye pigmentation?
A dermatologist might suggest a light chemical peel to lighten dark pigmentation under the eyes. Commonly these will include glycolic acid, retinoic acid or hydroquinone. Your dermatologist might also suggest a Jessner peel, which includes a combination of salicylic acid, lactic acid, and resorcinol.
Can you lose the pigment in your eye?
Send to a friend: Pigment dispersion syndrome is a condition that happens when pigment rubs off of the back of the iris of the eye when the fibers supporting the lens rub against it. This pigment is deposited in the trabecular meshwork of the eye, where the fluid drains out.
What does pigmentary glaucoma look like?
Pigmentary glaucoma is a type of secondary open-angle glaucoma characterized by heavy homogenous pigmentation of the trabecular meshwork, iris transillumination defects, and pigment along the corneal endothelium (Krukenberg spindle).
Is pigment dispersion syndrome painful?
The condition can cause episodes of symptoms, including the following: Blurred vision. Colored halos around lights. Mild ocular pain.
What are the different types of pigmentation in the cornea?

What causes copper discoloration in the cornea?
Formed when hemosiderin (iron) pigment is deposited deep in the epithelium Characteristic in eyes with keratoconus. Deposits of copper producing golden-brown discoloration in the peripheral cornea. Their earliest appearance consists of colored crescents at the superior and inferior quadrants of the cornea that eventually become circumferential.
How are lipid deposits formed in the cornea?
Lipid deposits begin inferiorly, then superiorly, and later extend circumferentially to form a white perilimbal band about 1 mm in diameter with a sharp outline peripherally and a more diffuse boundary centrally. A clear zone of cornea separates it from the limbus ( Fig. 6-1A ).
Is it possible to remove pigment from the cornea?
The pigmented regions of the eye are rarely removed surgery, due to the risks associated with this surgery. Medications may be used in some cases, though results are variable. In most cases, pigmentary keratitis cannot be fully reversed. The pigment may lighten over time, but it is uncommon for the pigmented deposits on the cornea to fully resolve.
