Transcript of Diseases of the eye

Diseases & Abnormal Conditions
of the Eye
Amblyopia
Lazy Eye; Results in poor vision in one eye
and is caused by the dominance of the other eye
Covering the good eye to stimulate the development of the "lazy" eye, exercises to strengthen the weak eye, corrective lenses, and/or surgery
Astigmatism
Abnormal shape or curvature of the cornea
that causes blurred vision. Light rays focus
on multiple areas of the retina.
Corrective lenses
Cataract
Occurs when a normally clear lens becomes
cloudy or opaque. This usually occurs gradually but may be a result of trauma
Surgical removal of the
lens; implantation of an
intraocular lens or prescription
glasses to correct the vision or compensate
for the removed lens
Conjunctivitis
Pink Eye; a contagious inflammation of the
conjunctiva and is usually caused by a bacterium
or virus
Antibiotics
Glaucoma
Increased intraocular pressure caused by an
excess amount of aqueous humor. Common after the age of 40 and is the leading cause of blindness
Usually controlled with medication that
decreases the amount of fluid produced or
improve the drainage.
Hyperopia
Farsightedness; Occurs when the light rays are not refracted sharply enough and the image focuses behind the retina
Corrected by the use
of convex lenses
Myopia
Nearsightedness; Occurs when the light rays are
refracted too sharply and the image focuses in front of the retina
Corrected by the use of concave lenses; laser to flatten the cornea; small incisions in the cornea to flatten it
Presbyopia
Farsightedness caused by a loss of lens elasticity; Light rays focus behind the retina ; is a result of the normal aging process
Corrective lenses or "reading" glasses
Strabismus
Disorder where the eyes do not move or focus
together. The eye may move inward or outward, or up or down.
Eye exercises, covering the good eye,
corrective lenses, and/or surgery on the muscles
of the eye
