Chronic glaucoma - Definition

Ask a question


Chronic glaucoma is another name for open-angle glaucoma. The optic nerve, transmitting images from the eye to the brain, is gradually destroyed due to excessive pressure in the eye. The progression usually affects both eyes and moves towards a total loss of vision or blindness. It's called chronic glaucoma when the progression occurs over several years: this is usually open-angle glaucoma, as opposed to another type of glaucoma that appears abruptly and whose risk of blindness is very great: narrow-angle glaucoma. The first signs of vision loss are recognized as advanced stages of this disease. Once vision loss begins, a visit to an ophthalmologist for a fundus test and, based on the suspected disorder, a possible measurement of intraocular pressure allows early treatment.
