Ocular Anatomy Flashcards
The vascular layer of the eye is the (name), with (#) structures.
Uvea, with 3 structures: iris, ciliary body, choroid.
The outer fibrous layer of connective tissue forms the (name) and (name).
Cornea, sclera.
The sclera is covered by a transparent (name).
Conjunctiva
The barrier between cornea to sclera and conjunctiva is called the (name).
Limbus.
Role of ciliary body? (2)
Produce components of aqueous humor, contains muscle that controls shape of lens.
The choroid is a network of (structure) with dense (structure) network that surrounds the (structure).
Blood vessels, capillary, retina.
Role of choroid?
Supplies nutrients to outer retinal layers.
The eyeball of an adult is around (measurement) in axial diameter.
24mm.
Emmetropia is when…
Optical power matches eye size.
Pterygium is when…, that is caused by…
A growth that starts on the clear tissue of the eye that can spread to the cornea, exposure to sunlight.
The … media is made of three components: (name 3 structures)
Refractive, aqueous, lens, vitreous.
Layers of the tear film? (3)
Lipid, aqueous, mucin (outer to inner)
Thickness of tear film?
4-8um
The cornea provides (fraction) of the eye’s optical power.
2/3
Thickness of cornea?
550um thick.
