PHACOMORPHIC GLAUCOMA

What is Phacomorphic Glaucoma?
Phacomorphic glaucoma is a form of secondary glaucoma that is typically due to a cataract. This can cause swelling of the cornea, an increase in intraocular pressure, and injection of the conjunctival and episcleral vessels.  Individuals with phacomorphic glaucoma are typically elderly, female, and often of small stature.

What causes Phacomorphic Glaucoma?Phacomorphic Glaucoma

When the lens increases in thickness due to a cataract it can push forward, pushing the iris forward along with it. This causes a decrease in the angle of the anterior chamber, which is the angle formed between the iris and the cornea and serves as the main drainage mechanism for the aqueous fluid inside the eye. If the aqueous is unable to drain properly, it can cause an increase in eye pressure and result in damage to the optic nerve.


Symptoms of Phacomorphic Glaucoma:

  • Pain

  • Blurred vision

  • Rainbow-colored halos around lights

  • Nausea

  • Vomiting

Patients will also usually have decreased vision prior to the acute episode due to the cataract.


Treatment of Phacomorphic Glaucoma:

Treatment for phacomorphic glaucoma is centered around lowering the pressure inside the eye. This is done with a combination of drops and oral medications, and typically surgery is required to allow the aqueous to properly circulate throughout the eye.
