Diseases affecting the eye.
Diseases or defects of the eye. Use vision disorders for other pathology involving visual neural pathways.
Impairment of health or a condition of abnormal functioning of the organ of sight.
Some eye problems are minor and fleeting. But some lead to a permanent loss of vision. Common eye problems include
cataracts - clouded lenses
glaucoma - damage to the optic nerve from too much pressure in the eye
retinal disorders - problems with the nerve layer at the back of the eye
conjunctivitis - an infection also known as pinkeye
your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision or everything looks dim or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye and inflammation. nih: national eye institute
