(Redirected from Eye disease)

The human eye is an organ that allows the gift of vision through it's interaction with the light. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can differentiate between about 10 million colors and is possibly capable of detecting a single photon. The eye is part of the sensory nervous system.

Any condition, disease or disorder of the any of the structures related to the eye come under the branch of medicine called Ophthalmology.

This is a partial list of human eye diseases and disorders.

The World Health Organization publishes a classification of known diseases and injuries, the International Statistical Classification of Diseases and Related Health Problems, or ICD-10. This list uses that classification.
