Halo Glaucomatosus

Halo glaucomatoida is a rare disease characterized by changes in the eye shell and cornea with the formation of additional optical reflexes around the pupil - halos. This defect is one of the most pronounced manifestations of age-related macular degeneration and over time leads to decreased vision, impaired color vision and other serious diseases. According to the World Health Organization, Halo glaucoma is the 13th leading cause of vision loss in the world. The incidence of the disease varies from 0.025% to 1.46% of patients with age-related macular degeneration. On the territory of the Russian Federation, the prevalence of the disease does not exceed 1%, but given the increase in incidence, it increases significantly.

Halo glaucoma is caused by abnormal growth of new blood vessels under the iris inside the eyeball. As a result, swelling occurs and blood vessels grow inside the retina, which leads to blurred vision.
