OPTHA LQ1 RECALLS Flashcards
Eye structure responsible for controlling the amount of light entering the eye
IRIS
junction between cornea and the sclera is known as
LIMBUS
Aqueous humor is secreted in the
CILIARY BODY
Thickest layer of the cornea *
CORNEAL STROMA
innermost layer of the cornea
ENDOTHILIUM
Primordia of the lens
SURFACE ECTODERM
what structure arises from all the
embryonic tissues
Vitreous
Superior oblique is supplied by this
nerve
Trochlear
sensory innervation of the eye
comes from this nerve
Trigemenal
white outermost layer of the eye
Sclera
levator superioris muscle (opens
eye
CN 3
Thick, gel-like substance that fills the
largest chamber of the eye and helps
to hold its spherical shape
VITREOUS HUMOR
the eyeball is fully developed at
age___
8
Part of the eye with the highest
refractive index
CORNEA
type of receptors that allow us to see
in low light and peripheral vision
Rods
A depression, or pit, in the center of
the retina that contains only cones;
provides for the most acute vision &
color sensitivity
Fovea centralis
middle and vascular of the eye
Choroid
facial nerve that closes the eye is
innervated b
CN 7
innermost layer of the retina
Internal limiting layer
.layers of the retina
10
Another term for nearsightedness
Myopia
Part of the eye with the highest refractive index
Cornea
Vascular layer of the eye
Choroid
Opening of the eye is supplied by this nerve
Oculomotor nerve
Closing of the eye is supplied by this nerve
Facial nerve
Another term for red deficiency
Protanopes
PROTANOPES- NO RED RECEPTORS
DEUTERANOPE- NO GREEN RECEPTORS
TRITANOPE- NO BLUE RECEPTORS
Light sensitive cells used for scotopic vision
Rods
What structure is directly above the pituitary fossa
Optic chiasm
Type of lens used to correct farsightedness
Convex
Type of visual defect in optic tract lesions
Homonymous Hemianopia
Difference in the color of the iris
Heterochromia
Primordia of the lens
Surface ectoderm
Reflex involving changing of the curvature of the lens for better near vision
Accommodation
Test for color
Ishihara TEst
Pit in the central retina containing only cones
Fovea centralis
Sensory innervation of the eye comes from this nerve
Trigeminal nerve
Refractive error where the light converges at the back of the retina
Hyperopia
Autonomic nerve supply responsible for dilatation of the eye
Sympathetic
Aqueous humor is secreted in the
Ciliary body
Loss of accommodation at age 40 plus
Presbyopia
Superior oblique is supplied by this nerve
Trochlear nerve
Blood supply of the central cornea
Avascular
Type of visual loss that fully recovers in minutes to hours
Amaurosis
Another term for lazy
