Glaucoma Secondary

Glaucoma secondary

Secondary glaucoma, or secondary glaucoma, is an eye disease in which uveitis and phakitis occur as a result of existing primary angle-closure glaucoma. This may occur due to the progression of open-angle glaucoma, characterized by a narrowing of the anterior chamber angle, resulting in hypoxia of the optic nerve sheaths. With open glaucoma, the risk of developing secondary hypoxia increases somewhat due to its negative relationship with increased IOP in the early stages.

Secondary angle-closure glaucoma is a common cause of an acute attack of glaucoma and is characterized by a high risk of acute, uncontrolled course of the disease. It is characterized by highly closed first and second chambers, the presence of blind spots in the peripheral visual field (decreased light sensitivity) and corneal opacities - a sign that distinguishes secondary angle-closure glaucoma from primary, subcompensated open-angle and pseudotumor of the anterior chamber angle. In patients with this form, there may be no decrease in visual acuity or a slight shift in visual acuity may be detected at the onset of the attack. After the attack has stopped, a sharp loss of the central visual field usually persists, followed by decompensation of IOP.
