What are the symptoms of glaucoma?

Variable symptoms: In open angle glaucoma the only signs are gradually progressive visual field loss, and optic nerve changes. In close angle glaucoma, there is sudden ocular pain, seeing halos around lights, red eye, very high intraocular pressure, nausea and vomiting, sudden decreased vision, and a fixed, mid-dilated pupil. Acute angle closure is an ocular emergency.

Depends on the type: Primary open-angle glaucoma signs and symptoms include: gradual loss of peripheral vision, usually in both eyes tunnel vision in the advanced stages acute angle-closure glaucoma signs and symptoms include: severe eye pain, nausea and vomiting (accompanying the severe eye pain) sudden onset of visual disturbance, often in low light blurred vision halos around lights reddening of the eye.

Depends: Most glaucoma is asymptomatic until end stage disease when the vision is decreased in both eyes. At that point, contrast, acuity, and peripheral vision are diminished. Thus, screening is key if at risk. A particular type called acute angle closure glaucoma with a sudden rise in eye pressure can have symptoms of red eye, severe eye pain, blurred vision, haloes, headache, nausea, vomiting...

There are no symptom: Glaucoma is a silent cause of blindness, hence there are usually no symptoms. You need to be examined by an ophthalmologist. Acute angle closure glaucoma is a rare condition that causes eye pain, headache, photophobia, blurry vision, nausea, and glare.

Loss of side vision: Most glaucoma is asymptomatic. Acute angle closure glaucoma is associated with pain, blurred vision, nausea and a red eye. Open angle glaucoma is not symptomatic until late in the progression of the disease. This fact is why routine eye exams are recommended to detect the disease early in its course before irreversible damage to the optic nerve and the vision has occurred .
