QuestionAnswer
A refractive error causing the light rays entering the eye to be focused irregularly on the retina due to an abnormally shaped cornea. Astigmatism
Inflammation of the eyelid margins stemming from seborrheic, allergic, or bacterial origin Blepharitis
The absence of vision or the need for assistive devices and/or assistance from other to accomplish daily activities due to the inability to see. Blindness
The lens in the eye becomes progressively cloudy losing its normal transparency and thus altering the perception of images due to the interference of light transmission to the retina. Cataract
A cyst or nodule on the eyelid resulting from an obstruction of a meibomian gland, which is responsible for lubricating the margin of the eyelid. Chalazion
Inflammation of the mucous membrane lining the eyelids and covering the front part of the eyeball Acute conjunctivitis
"Turning out" or eversion of the eyelash margins (especially lower eyelid) from the eyeball leading to exposure of the eyelid and eyeball surface and lining. Ectropion
"Turning in" of the eyelash margins ( especially the lower margins) resulting in the sensation similar to that of a foreign body in the eye (redness, tearing, burning, and itching). Entropion
Ocular disorders identified as a group due to the increase in intraocular pressure Glaucoma
Corneal inflammation caused by a microorganism, trauma to the eye, a break in the sensory innervation of cornea, a hypersensitivity reaction, or a tearing defect (may be due to dry eyes or ineffective eyelid closure). Keratitis
A refractive error in which the lens of the eye cannot focus on an image accurately, resulting in impaired distant vision that is blurred due to the light rays being focused in front of the retina because the eyeball is longer than normal. Myopia
A refractive error occurring after the age of 40, when the lens of the eye(s) cannot focus on an image accurately due to its decreasing loss of elasticity resulting in a firmer and more opaque lens. Presbyopia
An opening in the retina that allows leakage of vitreous humor. Retinal tear
The presence of inflammation in the white, outside covering of the eyeball, the sclera. Sceritis
A defined area in one or both eyes, which has a decreased visual function Scotoma
An infectious eye disease caused by Chlamydia trachomatis, which is chronic and will lead to blindness without effective treatment. Trachoma
A slow-growing cystic mass made up of epithelial cell debris and cholesterol found in the middle ear. Cholesteatoma
Hearing loss caused by the breakdown of the transmission of sound waves though the middle and/or external ear. Conductive deafness
An excessive accumulation of the waxlike secretions from the glands of the external ear canal Impacted cerumen
A refractive error in which the lens of the eye cannot focus on an image accurately, resulting in impaired distant vision that is blurred due to the light rays being focused in front of the retina because the eyeball is longer than normal. Myopia
A refractive error occurring after the age of 40, when the lens of the eye(s) cannot focus on an image accurately due to its decreasing loss of elasticity resulting in a firmer and more opaque lens. Presbyopia

An infectious eye disease caused by Chlamydia trachomatis, which is chronic and will lead to blindness without effective treatment. Trachoma
A slow-growing cystic mass made up of epithelial cell debris and cholesterol found in the middle ear. Cholesteatoma
Hearing loss caused by the breakdown of the transmission of sound waves though the middle and/or external ear. Conductive deafness
An excessive accumulation of the waxlike secretions from the glands of the external ear canal Impacted cerumen
Inflammation of the mastoid process, which is usually an acute expansion of an infection in the middle ear (otitis media). Mastoiditis
Inflammation of the outer or external ear canal, also called "swimmer's ear" Otitis externa
A middle ear infection, which predominately affects infants, toddlers, and preschoolers. Acute otitis media
A sterile collection of clear fluid in the middle ear Serous otitis media
A condition in which the footplate of the stapes becomes immobile and secured to the oval window, resulting in a hearing loss. Otosclerosis
Rupture of the tympanic membrane or eardrum Perforation of the tympanic membrane
Occurs when the eyelid partially or entirely covers the eye as a result of a weakened muscle Blepharoptosis
An inability to sharply perceive visual colors Color blindness (monochromatism)
A disruption of the cornea's surface epithelium commonly caused by an eyelash, a small foreign body, contact lenses, or a scratch from a fingernail Corneal abrasion
Occurs as a consequence on an 8- to 10-year duration of diabetes mellitus in which the capillaries of the retina experience scarring Diabetic retinopathy
An abnormal protrusion of the eyeball(s) usually with the sclera noticeable over the iris, typically due to an expanded volume of the orbital contents Exophthalmia
Abnormal eyesight in one-half of the visual field Hemianopia
Bacterial infection of an eyelash follicle or sebaceous gland originating with redness, swelling, and mild tenderness in the margin of the eyelash Hordeolum (stye)
A refractive error in which the lens of the eye cannot focus on an image accurately, resulting in impaired close vision that is blurred due to the light rays being focused behind the retina because the eyeball is shorter than normal Hyperopia
A bleed into the anterior chamber or the eye resulting as a postoperative complication or from a blunt eye injury. Hyphema (hyphemia)
Inadequate vision at night or in fiant lighting following reduction in the synthesis of rhodopsin, a compound in the rods of the retina that enables the eye to adjust to low-density light. Nyctalopia
Vertical, horizontal, rotary, or mixed rhythmic involuntary movements of the eyes caused by use of alcohol or certain drugs, lesions on the brain or inner ear, congenital abnormalities, nerve injury at birth, or abnormal retinal development. Nystagmus
A purulent inflammation of the conjunctiva and/or cornea in the newborn Ophthalmia neonatorum
An irregular growth developing as a fold in the bulbar conjunctiva on the nasal side of the cornea that can disrupt vision if it extends over the pupil Pterygium
The partial or complete splitting away of the retina from the pigmented vascular layer called the choroid, allowing the leakage of vitreous humor and thus creating a medical emergency Retinal detachment
Failure of the eyes to gaze in the same direction due to weakness in the muscles controlling the position of one eye. Strabismus
An adhesion in the eye that develops as a complication of trauma or surgery, or as a secondary condition of one of the following pathological conditions: cataracts, glaucoma, keratitis, or uveitis. Synechia
Inflammation of all or part of the middle vascular layer of the eye made up of the iris, the ciliary body, and the choroid. Uveitis
Hearing loss caused by the inability of nerve stimuli to be delivered to the brain from the inner ear due to damage to the auditory nerve or cochlea Sensorineural deafness
Infection or inflammation of the labyrinth or the inner ear, specifically the three semicircular canals in the inner ear, which are fluid-filled chambers and control balance Labyrinthitis
Chronic inner ear disease in which there is an over-accumulation of endolymph characterized by recurring episodes of vertigo, hearing loss, feeling of pressure, or fullness in the affected ear, and tinnitus. Meniere's disease
A purulent collection of fluid in the middle ear causing the person to experience pain, an elevation in temperature, dizziness, decreased hearing, vertigo, and tinnitus Suppurative otitis media
