2. Eale’s disease

3. Glaucoma

4. Cataract

Eales disease, also known as angiopathia retinae juvenilis, periphlebitis retinae, primary perivasculitis of the retina, is an ocular disease characterized by inflammation and possible blockage of retinal blood vessels, abnormal growth of new blood vessels (neovascularization), and recurrent retinal and vitreal hemorrhages.

The condition was first described in young adult men

Male predominance (up to 97.6%) has been reported in a majority of the series. The predominant age of onset of symptoms is between 20 and 30 years

Patients are often asymptomatic in the initial stages of retinal perivasculitis. Some patients may develop symptoms such as floaters, blurring vision, or even gross diminution of vision due to massive vitreous hemorrhage. Vision in these patients can be normal to hand movements or light perception only. Bilaterality is quite common (50-90%) patients.

In a significant number of patients, DNA of the bacterium Mycobacterium tuberculosis was detected by PCR
