Pigmentary Glaucoma: Symptoms, Causes, and Treatment

Pigmentary glaucoma is a type of glaucoma that occurs when pigments shed from the iris clog the drainage system in the eye, leading to increased intraocular pressure. This type of glaucoma is more common in men and people of African descent. In this article, we will discuss the symptoms, causes, and treatment of pigmentary glaucoma.

Symptoms of Pigmentary Glaucoma

The symptoms of pigmentary glaucoma are similar to other types of glaucoma. They include:

  1. Vision loss
  2. Blurred vision
  3. Halos around lights
  4. Eye pain
  5. Headaches
  6. Nausea and vomiting (in severe cases)

If you experience any of these symptoms, it is important to see an eye doctor as soon as possible.

Causes of Pigmentary Glaucoma

The exact cause of pigmentary glaucoma is unknown. However, it is believed that the shedding of pigments from the iris may be caused by the rubbing of the iris against the lens. This rubbing may occur in people who are nearsighted, have a flat cornea, or have a deep anterior chamber in the eye.

Other risk factors for pigmentary glaucoma include:

  • Being male
  • Being of African descent
  • Having a family history of glaucoma
  • Having diabetes
  • Being over the age of 40
Treatment of Pigmentary Glaucoma

Treatment for pigmentary glaucoma may include:

  1. Eye drops to lower intraocular pressure
  2. Oral medications to lower intraocular pressure
  3. Laser trabeculoplasty to improve drainage in the eye
  4. Traditional surgery to create a new drainage channel in the eye

It is important to note that early detection and treatment of pigmentary glaucoma can help prevent vision loss. Therefore, it is recommended that people over the age of 40, or those with a family history of glaucoma, have regular eye exams to check for signs of glaucoma.
