Eye Andexa Flashcards
The accessory structures of the eye that help protect and support the eyeball itself
Adnexa
The angles where the eyelids meet
Canthi
Thin mucous membrane that lines the inside of the eyelids
Conjunctiva
The pinkish, triangular-shaped structure located in the medial canthus that likely plays a role in moisture and lubrication of the eye
Caruncle
Also known as double vision, a visual disorder due to unequal action of the eyes muscles causing two images of a single object to be seen
Diplopia
In
Eso
Out
Exo
The six muscles that control eye movement and play and essential role in binocular vision
Extraocular muscles
The structures that help keep the eye moist, protect the eye from excessive light or injury, and prevent foreign bodies from entering the eye
Eyelids
Up
Hyper
Down
Hypo
The tear gland that produces tears to cleanse, lubricate, and protect the eye’s surface
Lacrimal gland
Thin sheet of connective tissue that extends to the tarsal plates of the eye
Orbital septum
Elevates the upper eyelid
Levator muscle
Sits below the levator muscle and assists in elevating the upper eyelid
Müllers muscle
The space between the upper and lower eyelids when the eyes are open
Palpebral fissure
A tendency for the eyes to turn from the normal position for binocular vision
Phoria
An element in the prescription that can be prescribed to help alleviate fusion difficulties.
Prism
The six muscles that control eye movement and play and essential role in binocular vision
Extraocular muscles
A deviation of turning of the eye from the normal position for binocular vision
Tropia
Structures that give the eyelids rigidity
Tarsal plates
moves the eye upward
Superior Rectus
rotates the eye downward and inward (toward the nose)
Superior Oblique
moves the eye inward (toward the nose)
Medial/Internal Rectus
moves the eye outward (away from the nose)
Lateral/External Rectus
moves the eye downward
Inferior Rectus
rotates the eye upward and inward (toward the nose)
Inferior Oblique
eye moves temporally
Abduction
eye moves nasally
Adduction
eye moves down
Depression
eye moves up
Elevation
top of eye rotates toward the nose
Intorsion
top of eye rotates away from the nose
Extorsion
both eyes move inward at the same time
Convergence
both eyes move outward at the same time
Divergence
A tendency for the eye to turn from the normal position.
Phoria
A definite deviation/turning of the eye from the normal position.
