Optician ABO

ophthalmologist - ANS examine and treat eye problems and to perform eye surgery

optometrist - ANS examine and treat eye problems, fit and prescribe glasses and contact
lenses, and prescribe visual therapy and low-vision aids

optician - ANS specialist who fills prescriptions for lenses

Cornea - ANS The clear tissue that covers the front of the eye

Sclera - ANS the white part of the eye that forms the orbit

Conjunctivitis - ANS Infection of the outer layer of the eye causing pink eye

Iris - ANS colored part of the eye around the pupil and controls the size of the pupil opening

lens - ANS the transparent structure behind the pupil that changes shape to help focus images
on the retina

the front of the eye - ANS Cornea
Iris
Pupil
Lens.

Five layers of the cornea - ANS Epithelium
Bowman's membrane
Stroma
Descemet's membrane
Endothelium

Epithelium - ANS This is the outer layer that protects your cornea, and it's the one that can get
scratched and be very painful if you get contact lenses that don't fit right.

Bowman's membrane - ANS This is a layer of tough fibers that helps protect your cornea.

Stroma - ANS This is the thickest part of your cornea, making up almost 90% of its width.

Descemet's membrane - ANS This thin layer covers the next layer of the cornea like a wrapper.

,endothelium - ANS This is the innermost layer of the cornea. It acts a little like a housekeeper,
mopping up and getting rid of excess water that accumulates in the cornea. Over the years, it
gets less efficient, and that can lead to hazy vision.

keratitis - ANS inflammation of the cornea

Keratoconus - ANS cone-shaped deformity of the cornea

aqueous humor - ANS fluid in the eye, found between the cornea and the lens

Back of the eye - ANS vitreous humor
retina
macula
optic nerve

vitreous - ANS Fluid inside the eye. Helps maintain eye's shape and holds the tissues inside
the eye in place. Composed mostly of water but has a gel like consistency.

Retina - ANS Contains sensory receptors that process visual information and sends it to the
brain

macula - ANS responsible for fine-detail vision. Located in the center back of the eye and is the
part of the retina used when you look directly at an object

optic nerve - ANS the nerve that carries neural impulses from the eye to the brain

superior rectus muscle - ANS Elevates the eyes (upward movement of the eyes)

inferior rectus muscle - ANS Depresses the eyes (downward movement of the eyes)

The two muscles that move your eye up and down are - ANS superior and inferior rectus
muscles

The two muscles that attach to the sides of your eyes and move them side-to-side are - ANS
lateral and medial rectus muscle

Lateral - ANS which moves your eye outward

Midial - ANS moves it inward (toward your nose)

inferior oblique muscle - ANS eye rolls, looks up and laterally

superior oblique muscle - ANS depresses eye and turns it laterally

,myopia - ANS nearsightedness

hyperopia - ANS farsightedness; difficulty seeing close objects when light rays are focused on a
point behind the retina

astigmatism - ANS defective curvature of the cornea or lens of the eye

presbyopia - ANS impaired vision as a result of aging

emmetropia - ANS normal vision

Anisometropia - ANS significant unequal refractive error between two eyes

amblyopia - ANS (lazy eye) occurs when these muscles can't work together in the right way to
focus both eyes on a target

strabismus - ANS Crossed eyes resulting from a weakness in eye muscles

strabismus takes many forms. The four common variants are - ANS Esotropia
Extropia
Hpertropia
Hypotropia

esotropia - ANS turning the eye inward toward the nose

exotropia - ANS outward turning of the eye, away from the nose

hypertropia - ANS eyes pointing upward

hypotropia - ANS eyes pointing downward

vision therapy - ANS include computer programs, lenses, prisms, eye patches, and eye-hand
coordination exercises.

cataract - ANS clouding of the lens of the eye

Glaucoma - ANS increased intraocular pressure results in damage to the retina and optic nerve
with loss of vision

Pachymetry - ANS Measurement of corneal thickness.

laser trabeculoplasty - ANS used to treat open-angle glaucoma by creating openings in the
trabecular meshwork to allow the fluid to drain properly

, peripheral iridectomy - ANS Procedure that creates a hole in the iris; used to relieve high
intraocular pressure

trabeculectomy - ANS surgical procedure to create a drain to reduce pressure within the eye

Age-related macular degeneration (AMD) - ANS a condition in which the macula degenerates,
gradually causing central vision loss

central serous chorioretinopathy - ANS unilateral

diabetic retinopathy - ANS occurs when diabetes damages the tiny blood vessels in the retina,
causing blood to leak into the posterior segment of the eyeball

floaters - ANS Particles of cellular debris that float in the vitreous fluid and cast shadows on the
retina

subconjunctival hemorrhage - ANS ruptured blood vessels in the white part of eye

sty - ANS infection of an oil gland of the eyelid

angle glaucoma - ANS pressure build up inside the eye, damage optic nerve because fluid can't
drain

open angle glaucoma - ANS damage on the optic nerve even if the pressure is normal or low

diabetes - ANS blood sugar is too high affecting blood vessels and the nerves

Glaucoma treatment - ANS Eye drops
eye surgery to help lower eye pressure

peripheral vision - ANS vision at the edges or side

macular degeneration - ANS progressive damage to the macula of the retina

2 form of macular degeneration - ANS dry
wet

wet macular degeneration - ANS progress quickly and can be arrested (but not reversed) with
surgery

dry macular degeneration - ANS form develops more slowly and isn't treatable

central vision - ANS The straight ahead part of your field of vision
