tumor arising from a developing retinal cell

retinopathy

disease of the retina

scleritis

inflammation of the sclera

scleromalacia

softening of the sclera

uveitis

inflammation of the uvea

uveoscleritis

inflammation of the uvea and sclera

xerophthalmia

condition of dry eye

amblyopia

reduced vision in one eye caused by disuse or misuse associated with strabismus, unequal refractive errors, or otherwise impaired vision. The brain suppresses images from the impaired eye to avoid double vision (also called lazy eye)

Anisometropia

significant unequal refractive error between two eyes

astigmatism

blurred vision caused by irregular curvature of the cornea or lens

cataract

clouding of the lens of the eye

chalazion

non-infected obstruction of an oil gland of the eyelid (also called meibomian cyst)

drusen

yellowish deposits located under the retina; commonly associated with aging and macular degeneration

Glaucoma

eye disorder characterized by optic nerve damage usually caused by the abnormal increase of intraocular pressure

hyperopia

farsightedness

hyphema

Hemorrhage into the anterior chamber of the eye usually from trauma

macular degeneration

progressive deterioration of the portion of the retina called the macula lutea, resulting in loss of central vision

myopia

nearsightedness

nyctalopia

poor vision at night or in faint light

nystagmus

involuntary, jerking movements of the eyes

Pinguecula

yellowish mass on the conjunctiva that may be related to exposure to ultraviolet light, dry climates, and dust

presbyopia

impairment of vision as a result of age

pterygium

thin tissue growing into the cornea from the conjunctiva, usually caused from sun exposure

retinal detachment

separation of the retina from the choroid, which disrupts vision and results in blindness if not repaired

retinitis pigmentosa

hereditary, progressive disease marked by night blindness with atrophy and retinal pigment changes

strabismus

condition in which the eyes look in different directions

sty

infection of an oil gland of the eyelid (also spelled stye and also called hordeolum)

blepharoplasty

surgical repair of the eyelid

cryoretinopexy

surgical fixation of the retina by using extreme cold

dacryocystorhinostomy

creation of an artificial opening between the tear sac and the nose

iridectomy

excision of the iris
