Acute angle-closure glaucoma can cause severe eye pain, redness, nausea, and vomiting. Immediate medical attention is necessary. -
Regular Eye Exams
A comprehensive eye exam can detect glaucoma. Tests include measuring intraocular pressure, inspecting the drainage angle, and assessing optic nerve damage.
Treatment Options
Various treatments can help manage glaucoma and prevent further vision loss. Here are some common treatments.
-
Medications
Eye drops are often the first line of treatment. They help reduce eye pressure by improving fluid drainage or decreasing fluid production. -
Laser Therapy
Laser treatments can help fluid drain from the eye. This is often used when medications are not enough. -
Surgery
In some cases, surgery may be necessary to create a new drainage path for the eye fluid or to remove tissue causing fluid buildup.
