Major functions & structure
convert light from the outside world into electrical nerve impulses.
impulses then travel to the part of the brain responsible for vision
outermost layer, known as the fibrous tunic, is composed of the cornea and sclera.
middle layer, known as the vascular tunic or uvea, consists of the choroid, ciliary body, pigmented epithelium and iris.
the cornea-is the clear bulging surface in front of the eye. It is the main refractive surface of the eye.
sclera- is the white of the eye
iris-heavily pigmented
lens-Transparent body enclosed in an elastic capsule
Made up of proteins and water
Retina-The center of the eyeball is towards the bottom of this figure and the back of the eyeball is towards the top.
vitreous humor-Fills the space between lens and retina
Transparent gelatinous body, also keeps the shape
Diseases associated with the eye
Refractive errors.
Cataracts - clouded lenses.
Optic nerve disorders, including glaucoma.
Retinal disorders - problems with the nerve layer at the back of the eye.
Macular degeneration - a disease that destroys sharp, central vision.
Diabetic eye problems.
