Pigment dispersion syndrome

Pigment Dispersion Syndrome is a medical condition that affects the eye, specifically the iris and the trabecular meshwork. It is characterized by the dispersion of pigment granules into the anterior chamber of the eye. This dispersion can lead to a variety of ocular complications, including glaucoma.

Causes

The exact cause of Pigment Dispersion Syndrome is not fully understood. However, it is believed to be related to the physical rubbing between the posterior surface of the iris and the zonular fibers of the lens. This friction leads to the dispersion of pigment granules into the anterior chamber of the eye.

Symptoms

The most common symptom of Pigment Dispersion Syndrome is the presence of pigment granules in the anterior chamber of the eye. Other symptoms may include blurred vision, halos around lights, and ocular pain. In some cases, the condition may lead to the development of glaucoma, which can cause additional symptoms such as loss of peripheral vision and increased intraocular pressure.

Diagnosis

Diagnosis of Pigment Dispersion Syndrome is typically made through a comprehensive eye examination. This may include a visual acuity test, a dilated eye exam, and an examination of the anterior chamber of the eye using a slit lamp. In some cases, additional tests such as gonioscopy or optical coherence tomography may be used to confirm the diagnosis.

Treatment

Treatment for Pigment Dispersion Syndrome is primarily aimed at managing the symptoms and preventing the development of glaucoma. This may include the use of eye drops to reduce intraocular pressure, laser therapy to improve the drainage of aqueous humor, or in severe cases, surgery.
