Beware of Narrow Angle Glaucoma


Valparaiso Ophthalmologist Scott Buck, M.D. cautioned patients to beware of the seriousness and symptoms of narrow angle or angle closure glaucoma. “Narrow angle glaucoma, especially with angle closure is a medical emergency as the potential for optic nerve damage and vision loss is quite high,” explained Dr. Buck of Northwest Indiana Eye & Laser Center.

The angle of the eye is located at the junction between the iris-the colored part of the eye-and the cornea which is clear curved dome in the front of the eye. Inside the eye-behind the iris-is a ring like structure called the ciliary body which continually produces fluid called aqueous humor. The aqueous fluid flows over the lens, then through the pupil and drains internally from the eye via the trabecular meshwork which is located at the “angle”. As long as aqueous is drained at roughly the same rate it is produced, the eye maintains a normal pressure.

Dr. Buck further explained, “The crystalline lens inside the eye grows throughout life and actually increases in size. As its size increases it can move the iris forward and slowly narrow or crowd the angle. Narrow angles tend to be seen more commonly as we age and some eyes are more predisposed to narrow angles than others. Narrow angles are more commonly found in people over the age of 40, females, farsighted or hyperopic patients, and in people of East Asian, African and Inuit descent.”

“Unlike open angle glaucoma which really produces no symptoms, symptoms that the angle is closing intermittently include episodes of blurred vision, perhaps seeing halos around objects, a headache-like pain around the eye or brow and even red eye,” explained Dr. Buck. “These symptoms can sometimes resolve spontaneously and may occur periodically over days or weeks. But, if the angle closes and does not reopen spontaneously, you may experience nausea and vomiting,” Dr. Buck warned. “If this happens you need to call us right away and tell us you need an immediate appointment.”
