Glaucoma and Physiological Optics

Glaucoma is a group of eye disorders in which the apparent gray-green color of the eye suffers from an attack of acute angle-closure glaucoma. Several pathologists have characterized diseases resulting from increased intraocular pressure. Glaucoma is generally classified into two main categories such as open angle and angle of closure. Open-angle glaucoma is less painful and does not have any of the symptoms as the disease progresses. Closed angle or closed angle have symptoms such as redness of eyes, nausea, vomiting.
