What is Pigmentary Glaucoma?
Pigmentary glaucoma is a type of secondary open-angle glaucoma caused by the dispersion of pigment granules from the iris into the eye’s drainage system. These pigment particles can clog the trabecular meshwork, leading to increased intraocular pressure and potential damage to the optic nerve.

Causes?
What causes Pigmentary Glaucoma?
The condition occurs when pigment from the back surface of the iris flakes off and accumulates in the drainage canals of the eye. Factors that contribute to pigment dispersion include:
- Anatomical variations of the iris and eye structure
- Physical activity or eye movements causing friction between the iris and lens
- Genetic predisposition
Symptoms?
What are the symptoms of Pigmentary Glaucoma?
Symptoms may develop slowly and can include:
- Blurred vision
- Halos around lights
- Eye discomfort or mild pain
- Redness of the eye
- Increased intraocular pressure (often detected during eye exams)
In many cases, early stages have no noticeable symptoms.
Diagnosis?
How is Pigmentary Glaucoma diagnosed?
Diagnosis involves:
- Comprehensive eye examination by an ophthalmologist
- Measurement of intraocular pressure (tonometry)
- Gonioscopy to inspect the drainage angle
- Observation of pigment granules in the trabecular meshwork
- Visual field testing to detect any loss of peripheral vision
- Optical coherence tomography (OCT) to assess optic nerve damage
Treatment?
How is Pigmentary Glaucoma treated?
Treatment aims to lower intraocular pressure and prevent optic nerve damage, including:
- Medications such as eye drops (prostaglandin analogs, beta blockers, alpha agonists)
- Laser therapy (laser trabeculoplasty) to improve drainage
- In rare cases, surgery may be necessary if medications and laser treatments are ineffective
- Lifestyle adjustments to avoid vigorous physical activity that may worsen pigment dispersion
Prognosis?
What is the outlook for someone with Pigmentary Glaucoma?
With early diagnosis and proper treatment, vision loss can often be prevented or slowed. Untreated pigmentary glaucoma may lead to permanent optic nerve damage and vision loss.

Prevention?
Can Pigmentary Glaucoma be prevented?
There is no guaranteed way to prevent pigmentary glaucoma, especially if there is a genetic predisposition. Regular eye exams and early detection are important for managing risk.
Support and Management?
How can individuals manage Pigmentary Glaucoma?
- Attend regular follow-ups with an eye specialist
- Adhere strictly to prescribed medications
- Report any changes in vision promptly
- Protect eyes from injury and avoid activities that increase pigment dispersion
- Maintain a healthy lifestyle to support overall eye health
