-opia
condition of vision
40
photophobia
extreme sensitivity to, and discomfort from, light
41
scotoma
blind spot vision
42
refractive errors
defects in the bending of light as it enters the eye, causing an improper focus on the retina.
43
astigmatism
distorted vision caused by an oblong or cylindrical curvature of the lens or cornea that prevents light rays from coming to a single focus on the retina
44
hyperopia
farsightedness
45
myopia
nearsightedness
46
presbyopia
impaired vison owing to old-age loss of accommodation
47
amblyopia
decreased vision in early life due to a functional defect that can occur as a result of strabismus, refractive errors or trauma.
48
aphakia
absence of the lens, usually after cataract extraction
49
blepharitis
inflammation of the eyelid
50
blepharochalasis, dermatochalasis
baggy eyelid
51
bleparoptosis
drooping of the eyelid usually caused by paralysis
52
diabetic retinopathy
disease of the retina in diabetics characterized by capillary leakage, bleeding, and new vessel formation, leading to scarring and loss of vision.
53
ectropion *on test*
outward turning of the rim of the eyelid
54
entropion *on test*
inward turning of the rim of the eyelid
55
glaucoma
group of diseases of the eye charactized by increased intraocular pressure that results in damage to the optic nerve, producing defects in vision
56
hordeolum
sty
57
iritis
inflammation of the iris
58
keratitis
inflammation of the cornea
59
retinal detachment
separation of the retina from the underlying epithelium, disrupting vision and resulting in blindness if not repair surgically.
60
scleritis
inflammation to the sclera
61
trichiasis
misdirected eyelashes that rub on the conjunctiva or cornea
62
distance visual acuity
measure the ability to see the details and shape of identifiable objects from a specified distance, typically using a Snellen Chart
63
fluorescein angiography
visualization and photograpthy of retinal and choroidal vessels made as fluresein dye, which is injected into a vein, circulates through the eye
64
ophthalmoscopy
use of an ophthalmoscope to view the interior of the eye
65
refraction
measurement of refractive error using a phoropter to determine best corrected vision and prescription for eye glasses or contact lenses
66
phoropter
instrument that holds corrective lenses in front of the eye to determine optical correction
67
slit-lamp biomicroscopy
use of a tabletop microscope to examine the eye especially the cornea, lens, fluids, and membranes
68
blepharoplasty
repair of an eyelid
69
cataract extraction
excision of a cloudy lens from the eye
70
cryoretinopexy
use of intense cold to seal a hole or tear in the retina

agent that paralyzes the ciliary muscle and powers of accommodation
81
mydriatic
agent that cause dilation of the pupil
82
miotic
agent that causes the pupil to contract
