6–67 million [ 2][ 4] Glaucoma is a group of eye diseases that lead to damage of the optic nerve, which 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]
Primary juvenile glaucoma is a subtype of primary congenital glaucoma that develops due to ocular hypertension and is diagnosed between three years of age and early adulthood. [3] [4] It is caused due to abnormalities in the anterior chamber angle development that obstruct aqueous outflow in the absence of systemic anomalies or other ocular ...
Currently, the best sign of pediatric glaucoma is an IOP of 21 mm Hg or greater present within a child. [62] 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. [62]
[4] [19] Another found that PEX was present in 6% of an "open-angle glaucoma" group. [20] Pseudoexfoliation syndrome is considered to be the most common of identifiable causes of glaucoma. [5] If PEX is diagnosed without glaucoma, there is a high risk of a patient subsequently developing glaucoma. [3] Country and region. Prevalence of PEX ...
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
The first glaucoma drainage implant was developed in 1966. [2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants.
Ophthalmology ( / ˌɒfθælˈmɒlədʒi /, OFF-thal-MOL-ə-jee) [ 1] is a clinical and surgical specialty within medicine that deals with the diagnosis and treatment of eye disorders. [ 2] A former term is oculism . An ophthalmologist is a physician who undergoes subspecialty training in medical and surgical eye care. [ 3]
Secondary glaucoma is a collection of progressive optic nerve disorders associated with a rise in intraocular pressure (IOP) which results in the loss of vision. In clinical settings, it is defined as the occurrence of IOP above 21 mmHg requiring the prescription of IOP-managing drugs. [1] It can be broadly divided into two subtypes: secondary ...
