a disease of the eye marked by increased pressure within the eyeball that can result in damage to the optic disk and gradual loss of vision
|
|
hordeolum
|
an inflamed swelling of a sebaceous gland at the margin of an eyelid --
|
|
hyperopia
|
a condition in which visual images come to a focus behind the retina of the eye and vision is better for distant than for near objects -- called also farsightedness, hypermetropia
|
|
iritis
|
inflammation of the iris of the eye

|
keratitis
|
inflammation of the cornea of the eye characterized by burning or smarting, blurring of vision, and sensitiveness to light and caused by infectious or noninfectious agents -- called also corneitis
|
|
macular degerneration
|
progressive deterioration of the macula lutea resulting in a gradual loss of the central part of the field of vision
|
|
myopia
|
a condition in which the visual images come to a focus in front of the retina of the eye because of defects in the refractive media of the eye or of abnormal length of the eyeball resulting especially in defective vision of distant objects -- called also nearsightedness
|
|
nystagmus
|
involuntary usually rapid movement of the eyeballs (as from side to side) occurring normally with dizziness during and after bodily rotation or abnormally following head injury or as a symptom of disease
|
|
photophobia
|
1 : intolerance to light; especially : painful sensitiveness to strong light
2 : an abnormal fear of light |
|
presbyopia
|
a visual condition which becomes apparent especially in middle age and in which loss of elasticity of the lens of the eye causes defective accommodation and inability to focus sharply for near vision
|
|
pterygium
|
1 : a triangular fleshy mass of thickened conjunctiva occurring usually at the inner side of the eyeball, covering part of the cornea, and causing a disturbance of vision
2 : a forward growth of the cuticle over the nail |
|
retinopathy
|
any of various noninflammatory disorders of the retina including some that cause blindness
|
|
strabismus
|
inability of one eye to attain binocular vision with the other because of imbalance of the muscles of the eyeball -- called also heterotropia, squint
|
|
blepharoplasty
|
plastic surgery on an eyelid especially to remove fatty or excess tissue

the ear flap. a : PINNA b : an atrium of the heart
2 : an angular or ear-shaped anatomical lobe or process (as an auricular appendage of the heart) |
|
tympanic membrane
|
a thin membrane separating the middle ear from the inner part of the external auditory canal that vibrates in response to sound energy and transmits the resulting mechanical vibrations to the structures of the middle ear -- called also eardrum, tympanum
|
|
cerumen
|
:EARWAX

|
eustachian tube
|
a bony and cartilaginous tube connecting the middle ear with the nasopharynx and equalizing air pressure on both sides of the tympanic membrane -- called also auditory tube, pharyngotympanic tube

otorrhagia
|
hemorrhage from the ear
