A
lazy eye, common cause of vision loss in children, occurs when the nerve pathway from one eye fails to develop
25
strabisums
one or both eyes are crossed
26
cataract
the transparency of the lens of the eye is reduced
27
conjunctivitis
conjunctiva is a thin membrane that covers the anterior exposed part of the eye and the inner eyelid. May become inflamed when exposed to bacteria or viruses or injury
28
dacryolithiasis
lacrimal apparatus is a tear-forming gland with associated tubes and chambers, mainly located near the medial side of each eyeball. The presence of rocky particles in the apparatus that leads to inflammation
29
detached retina
occurs when the retina tears away fro the choroid layer of the eye causing blindness, can be caused by severe blow to the head, high blood pressure or old age
30
diplopia
double vision may result from weakened extrinsic eye muscles, defects in the lens, or a condition of the brain
31
hordeolum
a meibomian gland is a small gland in the eyelid that secretes lubricating fluid onto the conjunctiva. An infection of this gland produces a local swelling of the eyelid known as a hordeolum. chronic form is called chalazion greek word for STY
32
iritis
during a bacterial infection of the eye parts of the eye may become inflamed. When the iris is affected, the condition is known as iritis
33
macular degeneration
the macula lutea is a small area of the retina that contains a high density of photoreceptors, known as cone cells.. degeneration leads to loss of visual focus. AMD (age related macular degeneration) because most common cause is age
34
opthalmomalacia
softening of the eye form of eye disease ophthalmology
35
ophthalmoplegia
paralysis of the eye muscles disease ophthalmology
36
retinopathy
a general term for a disease of the retina, occurs with diabetes
37
refractive errors
conditions of the eye that results in a reduction of vision or low vision resulting from an error in the refraction of light as it travels
38
list of refractive errors
myopia (nearsightedness), hyperopia (farsightedness), astigmatism
39
emmetropia
the normal condition of the eye
40
astigmatism
condition without a point, curvature of the eye producing blurred vision

cataract extraction
a lens damage by a cataract is surgically removed and replaced with an artificial lens called an intraocular lens
(IOL)
43
phacoemulsification
or phaco, the use of sound waves to break up the lens so that it can be removed by suction
44
corneal grafting
treatment for corneal damag, cornea is replaced by a synthetic one
45
cryopexy
detached retina, tiny holes are created through the retina by laser treatment, which welds the retina back in place or freeze treatment, or scleral buckling
46
dacryocystorhinostomy
to treat dacryocystitis, antibiotic eye drops often used but if not this is. a channel is surgically created between the nasal cavity and lacrimal sac to promote drainage
47
LASIK
laser-assisted in situ keratomileusis laser reshaping the corneal tissue beneath the surface of the cornea to correct vision disorders
48
optometrist
health professional not a physician trained to examine eyes and to correct vision problems and eye disordes
49
ophthalmologist
physician who specializes in the study and treatment of diseases associated with the eyes
50
-acusis

pain in the ear or ear ache
55
otorrhagia
bleeding from the external ear canal
56
otorreha
abnormal drainage of pus from the ear
57
tinnitus
ringing or buzzing sensation in the ears and vertigo
58
cholesteatoma
common source of partial hearing loss and ear drainage, formation of a cyst-like ball of epithelial cells in the middle ear. tumor of cholesterol
59
masoiditis
inflammation of the mastoid process, bacterial infections, can cause deafness or impaired hearing
60
meniere disease
a chronic disease of the inner ear includes symptoms of vertigo or dizziness and tinnitus
61
otitis
the general term for inflammation of the ear
62
otitis media
local pain and temporary loss of hearing, common in children, caused by bacterial infection, (OM)
63
otopathies
diseases of the ear
64
otosclerosis
an abnormal formation of bone within the ear, usually between the stapes and the oval window, causes progressive loss of hearing
65
presbyacusis
a gradual loss of hearing with advancing age
66
labyrinth/o

one who specializes in hearing disorders
69
audiometry
procedure involving the measurement of hearing
70
cochlear implant
is a small electronic device that helps to provide a sensation of sound to a person who is profoundly deaf or very heard of hearing. contains an inner and outer part
71
labyrinthectomy
the inner ear is surgically removed and replaced with a synthetic hearing device
72
mastoidectomy
surgical removal of part of the mastoid process
73
