the process whereby the eyes make adjustments for seeing objects at various distances

of the eyes, include the orbit, eye muscles, eyelids, eyelashes, conjunctiva, and lacrimal apparatus

dimness of vision or the partial loss of sight without detectable disease of the eye

an error of refraction in which only objects located a finite distance from the eye are focused on the retina

a condition in which the pupils are unequal in size

a condition in which the eye does not focus properly because of unequal curvatures of the cornea

specializes in the measurement of hearing function and the rehabilitation of persons with hearing impairments

drooping of the upper eyelid

loss of transparency of the lens of the eye

a localized swelling of the eyelid resulting from obstruction of one of the oil-producing glands of the eyelid

inflammation of the conjunctiva

surgical repair of the conjunctiva

the simultaneous inward movement of both eyes in an effort to maintain single binocular vision as an object comes nearer

an inflammation of the lacrimal sac that is associated with faulty tear drainage

the perception of two images of a single object

the turning outward of the edge of the eyelid

the normal relationship between the refractive power of the eye and the shape of the eye that enables light rays to focus correctly on the retina

the turning inward of the edge of the eyelid

strabismus characterized by an inward deviation of one eye in relation to the other

inflammation of the eustachian tube

strabismus characterized by the outward deviation of one eye relative to the other

a surgical procedure in which a new opening is made in the labyrinth of the inner ear to restore hearing

increased intraocular pressure that damages the optic nerve and may cause the loss of peripheral vision and eventually blindness

blindness in one half of the visual field

an infection of one or more glands at the border of the eyelid

a defect in which light rays focus beyond the retina

a diagnostic test in which a dye is injected into the arm and pictures are taken as the dye passes through the blood vessels in the retina

a condition in which the individual has difficulty seeing at night

involuntary, constant, rhythmic movement of the eyeball

a specialist in diagnosing and treating diseases and disorders of the eye

holds a Doctor of Optometry (OD) degree and specializes in measuring the accuracy of vision to determine whether corrective lenses or eyeglasses are needed.

inflammatioin of the middle ear usually associated with an upper respiratory infection that is most commonly seen in young children

a buildup of pus within the middle ear

a fluid build in the middle ear that may follow acute otitis media or be caused by obstruction of the eustachian tube
