What does pigmentation in the eye mean?
Pigment is the material that gives your iris its color. Pigment dispersion syndrome (PDS) happens when the pigment rubs off the back of your iris. This pigment then floats around to other parts of the eye. The tiny bits of pigment can clog your eye’s drainage angle. This can cause eye pressure problems.
Is pigment dispersion serious?
When the pressure is great enough to cause damage to the optic nerve, this is called pigmentary glaucoma. As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless….

What causes pigment dispersion syndrome?
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 is pigment Terry glaucoma?
Learn about a form of glaucoma that results from pigment granules that flake off from the iris (the colored part of the eye) and clog the eye’s drainage system, thereby resulting in high eye pressure, and subsequent damage to the optic nerve.
How can I reduce my eye pigmentation?
Natural remedies
- According to a 2012 study in Phytotherapy Research , the active compound in turmeric may reduce melanin synthesis.
- Aloe vera may reduce melanin production after sun exposure.
- People also use lemon juice to reduce skin pigmentation.
- Green tea has a compound called epigallocatechin gallate (EGCG).
How do you stop pigmentation from spreading?
How to get rid of hyperpigmentation
- Avoid exposure to the sun. Use a sunscreen with an SPF of 30 or higher to protect the skin and stop hyperpigmentation from becoming darker.
- Avoid picking at the skin. To prevent hyperpigmentation from forming after an injury, avoid picking at spots, scabs, and acne.
Can you go blind from pigmentary glaucoma?
Blindness due to pigmentary glaucoma is rare. In a study of 113 patients with PDS and pigmentary glaucoma, 3 eyes in 2 patients were blind. Progression of the disease, however, is common. Ten percent of patients with PDS progressed to pigmentary glaucoma at 5 years and 15% developed pigmentary glaucoma by 10 years.
Can pigment dispersion syndrome be cured?
Pigment dispersion syndrome is a risk factor for developing glaucoma and patients who have this condition should be monitored regularly. Patients with pigmentary glaucoma can be treated successfully. Thankfully, with modern treatments, many patients are able to maintain excellent vision.
Can brown eyes turn green?
If the color of one or both eyes changes suddenly and significantly, see an eye doctor as soon as possible. It is particularly dangerous for eyes to change from brown to green, or from blue to brown. Major changes in the iris’ pigment can indicate illness, such as: Horner’s syndrome.
Can pigmentation be removed?

Where does pigmentation occur in the trabecular meshwork?
Trabecular pigmentation usually appears deep within the posterior trabecular meshwork ( 5‑9 ). Sometimes pigment is deposited on the surface of the posterior trabecular meshwork ( 5‑10) or over the anterior trabecular meshwork and Schwalbe’s line ( 5‑11 ). Heavy pigmentation may cover all angle structures ( 5‑12 and 5‑13 ).
What causes heavy pigmentation on the angle of the eye?
Heavy pigmentation may cover all angle structures ( 5‑12 and 5‑13 ). Increased pigmentation of the angle can be caused by many pathological processes; these are discussed in detail in Chapter 9. Heavy angle pigment can accumulate in a line anterior to Schwalbe’s line as a Sampaolesi’s line.
Where to look for pigment in the cornea?
The posterior surface of the central cornea should be carefully examined for the presence of pigment.
Where is the anterior chamber of the eye?

Where are the pigments located in a dog’s eye?
In dogs, they usually are free-floating, pigmented spheres in the aqueous humor within the pupil and anterior and posterior chambers.
