What are the symptoms of glaucoma?

Primary Open Angle Glaucoma

Increased intraocular pressure is very slow. The pressure values are not very high so that the visual field loss progresses slowly. This visual field loss is unlikely to be detected by the patient. In early stages does not decrease central vision. The amount of vision is not affected until the glaucoma is very advanced.

Because this condition is not generally recognized until it is advanced, a check is performed for diagnosis as part of the routine ophthalmologist when testing vision. The ophthalmologist will check your eye pressure, examine the nerve at the back of the eye and check the field of view, if applicable. Since the primary open-angle glaucoma is rare in people under 40 years, these tests are performed after this age.
Primary angle-closure glaucoma

In this disorder, the pressure inside the eye rises rapidly and can be very painful. The eye is usually red and the vision becomes blurred. The patient may notice halos around lights. Often can be accompanied by headache, nausea and vomiting. This condition is more common in farsighted people who have an eye shorter than normal which facilitates the closing of the drainage pathways of aqueous humor.

Other types of glaucoma

In other types of glaucoma symptoms of other types of glaucoma vary with the underlying cause.
