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]
Diagnosis is by an eye exam. [2] The World Health Organization (WHO) estimates that 80% of visual impairment is either preventable or curable with treatment. [1] This includes cataracts, the infections river blindness and trachoma, glaucoma, diabetic retinopathy, uncorrected refractive errors, and some cases of childhood blindness. [14]
The first AIDS-related death occurs in Australia, in the city of Melbourne. The Hawke Labor government invests in a significant campaign that has been credited with ensuring Australia has one of the lowest HIV infection rates in the world. AIDS is diagnosed in Mexico for the first time. However, HIV can be traced in the country to 1981.
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 ...
Uveitic glaucoma is a progressive stage of anterior noninfectious uveitis. Patients diagnosed with anterior noninfectious uveitis may also develop glaucoma; in this case the condition is termed uveitic glaucoma. Uveitic glaucoma can arise from the inflammation that occurs in uveitis; from steroid treatment for uveitis; [6] or a combination of both.
The sailor had first presented symptoms in 1969, eight years after he first spent time in ports along the West African coastline. A gonorrhea infection during his first African voyage shows he was sexually active at this time. Tissue samples from the sailor and his wife were tested in 1988 and found to contain HIV-1 (Group O).
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 ...
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 ...
