Understanding Chronic Angle-Closure Glaucoma, Unspecified Eye

Glaucoma is a group of eye diseases that damage the optic nerve and can lead to vision loss. Chronic angle-closure glaucoma is a type of glaucoma that occurs when the angle between the iris and the cornea is gradually narrowed, leading to gradually increasing intraocular pressure.

Chronic angle-closure glaucoma is often asymptomatic until it reaches an advanced stage. At this point, individuals may experience blurred vision, halos around lights, eye pain, and headaches. If left untreated, chronic angle-closure glaucoma can lead to permanent vision loss.

Diagnosis and Treatment

Diagnosis of chronic angle-closure glaucoma typically involves a comprehensive eye examination, including measurement of intraocular pressure, examination of the optic nerve, and evaluation of the drainage angle. Additional testing, such as visual field testing and optical coherence tomography (OCT), may also be performed to assess the extent of vision loss and damage to the optic nerve.

Treatment options for chronic angle-closure glaucoma include medications, laser treatment, and surgery. Medications, such as eye drops, can help to lower intraocular pressure. Laser treatment, such as laser peripheral iridotomy, can create a small hole in the iris to improve fluid drainage. Surgery, such as trabeculectomy, involves creating a new drainage channel to lower intraocular pressure.

Preventing Chronic Angle-Closure Glaucoma

While chronic angle-closure glaucoma cannot be prevented, early detection and treatment can help to prevent vision loss. It is recommended that individuals over the age of 40 have a comprehensive eye exam every 1-2 years, or as recommended by their eye doctor. Those with a family history of glaucoma, as well as individuals with certain medical conditions, such as diabetes, should be especially vigilant about getting regular eye exams.

  1. Visit an eye doctor regularly for comprehensive eye exams
  2. Notify your eye doctor if you have a family history of glaucoma
  3. Notify your eye doctor if you have any medical conditions that may increase your risk of developing glaucoma
  4. Follow your eye doctor's recommendations for treatment and monitoring

Chronic angle-closure glaucoma is a serious condition that can lead to permanent vision loss if left untreated. However, with early detection and treatment, vision loss can be prevented. If you are experiencing any symptoms of chronic angle-closure glaucoma, or if you are due for a routine eye exam, contact your eye doctor to schedule an appointment.
