Acute Narrow-Angle Glaucoma

Acute narrow-angle glaucoma may cause vision loss.

An eye with glaucoma has increased pressure that will damage the optic nerve and eventually affect peripheral vision if left untreated. Acute narrow-angle glaucoma occurs suddenly and can result in permanent damage to the eye. Knowing the symptoms may preserve eyesight.

Narrow-Angle Glaucoma

Inside, near the front of the eye, is a narrow canal that allows fluid to drain. If the canal is too narrow or closed, the fluid builds up and increases intraocular pressure.

Signs and Symptoms

Acute narrow-angle glaucoma causes extreme pain in the eye. Vomiting and light sensitivity will likely occur with an acute attack.

Diagnosis

An eye doctor will immediately check the pressure of the eye. An extremely high eye pressure will confirm the diagnosis.

Treatment

Eye drops to lower the eye pressure will be ordered immediately, and the pressure will be checked frequently to determine if the pressure is down. Some cases require surgery to help with drainage.

Considerations

Glaucoma is a hereditary disease. If a family member has glaucoma, be sure to have a regular eye exam to check for increased pressure and angle closure.
