Glaucoma is an 
eye disease that is characterized by increased pressure in the eyeball.  Most commonly it results from an obstruction of the outflow of fluid in the eye. If glaucoma is not treated, this condition can damage the 
optic disc[?] of the 
retina and impair vision (sometimes progressing to 
blindness). Usual symptoms include pain, and can be slow or fast acting. If it is the latter immediate medical treatment is advised.  People with family history of glaucoma should be screened for the disease.
Diabetics are prone to glaucoma.
