Chronic Angle-Closure Glaucoma: A Brief Overview

Chronic angle-closure glaucoma is a type of glaucoma that occurs when the angle between the iris and the cornea is closed or nearly closed, causing a blockage in the drainage of aqueous humor. This can lead to increased intraocular pressure, which can damage the optic nerve and cause vision loss.

Unspecified eye refers to the fact that this type of glaucoma can affect either eye and moderate stage means that the condition is not in its early stages but has not yet progressed to the advanced stage.

Causes and Risk Factors

The exact cause of chronic angle-closure glaucoma is not known, but it is believed to be related to the anatomy of the eye. Factors that may increase the risk of developing this condition include:

1. Age (over 60 years old)
2. Farsightedness (hyperopia)
3. Asian or Inuit ethnicity
4. Family history of glaucoma

Symptoms and Diagnosis

Chronic angle-closure glaucoma typically does not cause any symptoms in its early stages, which is why regular eye exams are important for early detection and treatment. As the condition progresses, symptoms may include:

• Gradual loss of peripheral vision
• Hazy or blurred vision
• Halos around lights
• Frequent changes in eyeglass prescription

Diagnosis of chronic angle-closure glaucoma involves a comprehensive eye exam, including measurement of intraocular pressure, examination of the optic nerve, and visual field testing.

Conclusion

Chronic angle-closure glaucoma is a serious eye condition that can lead to vision loss if left untreated. Although the exact cause is unknown, certain risk factors can increase the likelihood of developing this condition. Regular eye exams are important for early detection and treatment. If you experience any symptoms of chronic angle-closure glaucoma, it is important to schedule an appointment with your eye doctor as soon as possible.
