The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision [3] (pseudoexfoliation glaucoma, exfoliation glaucoma). As worldwide populations become older because of shifts in demography, PEX may become a matter of greater ...
Glaucoma is a group of eye diseases that can lead to damage of the optic nerve. The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5]
It most commonly occurs in people over the age of fifty and in the United States is the most common cause of vision loss in this age group. [ 1 ] [ 3 ] About 0.4% of people between 50 and 60 have the disease, while it occurs in 0.7% of people 60 to 70, 2.3% of those 70 to 80, and nearly 12% of people over 80 years old.
Ischemic optic neuropathies are classified based on the location of the damage and the cause of reduced blood flow if known. [3] Anterior ischemic optic neuropathy (AION) includes diseases that affect the optic nerve head and cause swelling of the optic disc. These diseases often cause sudden rapid visual loss in one eye.
Aphakic and pseudophakic glaucoma: Aphakic glaucoma is a common side-effect of cataract surgery which causes an increase in IOP. [ 2 ] Corticosteroid -induced glaucoma: Corticosteroids is a risk factor for the development of secondary glaucoma, as there had been increased IOP observed as a drug side-effect.
Because uveitic glaucoma is a progressive stage of anterior non infectious uveitis, uveitic glaucoma involves signs and symptoms of both glaucoma and uveitis.. Patients with acute non infectious anterior uveitis may experience the following symptoms: pain, blurry vision, headache, photophobia (discomfort or pain due to light exposure), or the observance of haloes around lights.
Angle-closure glaucoma should be considered if there is painful loss of vision with a red eye, nausea or vomiting. [4] The eye pressure will be very high typically greater than 40 mmHg. [5] Emergent laser treatment to the iris may prevent blindness. [4]
Currently, the best sign of pediatric glaucoma is an IOP of 21 mm Hg or greater present within a child. [63] One of the most common causes of pediatric glaucoma is cataract removal surgery, which leads to an incidence rate of about 12.2% among infants and 58.7% among 10-year-olds. [63]
