37
Uvea
Middle layer composed of 3 parts
38
Chordid
Vascular and pigmented layer of the Uvea. Located in the posterior portion of the eyeball. Provides nourishment for the retina.
39
Ciliary body
Contains muscle that controls the shape of the lense. Process called accommodation.
40
Iris

41
Retina
Innermost layer of the eye and the actual visual receptors. Two specialized cells: rods and cones.
42
Rods
Function in dim light, provide low visual acuity and do not respond to color
43
Cones
Active in bright light, high visual acuity and respond to color.
44
Fovea
Tiny depression in the retina near the optic never with a high concentration of cones. Area of highest visual acuity.
45
Vitreous body
Jelly like filling of the eye that refracts light.
46
Aqueous humor
Fluid that fills the anterior of the lense. Maintains the cornea’s shape and refracts light.

69
Hyperopia
Farsightedness. Eyeball is to short and images form behind the retina.
70
Presbyopia
Shortening of the eye due to aging.
71
Astigmatism
Irregularity in the cornea or the lens that distorts light entering the eye and blurs vision.

73
Trachoma
Inflammation of the conjunctiva and cornea caused by chlamydia trachomatis.
74
Ophthalmia neonatrum

77
Dry AMD

78
Wet AMD
Abnormal blood vessels grow under the retina that cause it to detach.
