Eye conditions and diseases leave the eye vulnerable to many
disorders. From common allergies to rare diseases, the human eye
can be affected by any number of maladies, causing issues - ranging
from general discomfort to a complete loss of vision. The overall
health of the eye can be compromised at any time, often without
any undue symptoms until irreversible damage is done. This risk
increases exponentially as the individual grows older, a fact
that might well translate into a higher percentage of eye-related
ailments in the future as the world's population continues to
live longer. While certain diseases, such as trachoma, might be
unheard of in some areas of the world, they can be at near-epidemic
levels in others. Also, common conditions such as allergies might
seem benign to some, but others across the globe might suffer
to such an extent and degree as to lower the quality of life for
an entire community.
Allergic Conjunctivitis is inflammation
of the conjunctiva (the membrane covering the white part of the
eye) due to allergy. Although allergens differ between patients,
the most common cause is hay fever.
Astigmatism is an optical defect,
whereby vision is blurred due to irregular curvature of the cornea
or lens. In corneal astigmatism, the cornea is ellipsoidal (like
an egg) rather than spherical, which reduces the cornea's ability
to focus light.
Blepharitis is characterized by
inflammation of the eyelid margins. Blepharitis usually causes
redness of the eyes and itching and irritation of the eyelids
in both eyes.
Cataracts are opacities that develop
in the crystalline lens of the eye or in its envelope. Early on
in the development of age-related cataract the power of the crystalline
lens may be increased, causing near-sightedness (myopia), and
the gradual yellowing and opacification of the lens may reduce
the perception of blue colors. Cataracts typically progress slowly
to cause vision loss and are potentially blinding if untreated.
Cytomegalovirus (CMV) is a DNA
virus found in almost everyone, and is usually fought off by the
immune system. For people who are immunocompromised by diseases,
transplants, or chemotherapy, the virus is not adequately destroyed
and can cause damage to the eye and the rest of the body.
Color Blindness, or color vision
deficiency, is the inability to perceive differences
between some or all colors that other people can distinguish.
Conjunctivitis (Pink Eye) is
an inflammation of the conjunctiva (the outermost layer of the
eye and the inner surface of the eyelids), most commonly due to
an allergic reaction or an infection (usually bacterial or viral).
Diabetic Retinopathy is retinopathy
(damage to the retina) caused by complications of diabetes mellitus,
which could eventually lead to blindness. It is an ocular manifestation
of systemic disease which affects up to 80% of all diabetics who
have had diabetes for 15 years or more.
known as double vision, is the simultaneous perception of two
images of a single object. These images may be displaced horizontally,
vertically, or diagonally (i.e. both vertically and horizontally)
in relation to each other.
Dry Eye Syndrome (Keratoconjunctivitis
Sicca) is an eye disease caused by decreased tear production or
increased tear film evaporation, with common symptoms include
dryness, burning, and a sandy-gritty eye irritation that gets
worse as the day goes on.
Floaters are deposits of various
size, shape, consistency, refractive index, and motility within
the eye's normally the transparent, colorless, gelatinous
mass that fills the space between the lens of the eye and the
retina lining the back of the eye.
Fuchs' Dystrophy, also known
as Fuchs' endothelial dystrophy, is a slowly progressing corneal
disease that usually affects both eyes and is slightly more
common in women than in men. New surgical modalities are gaining
popularity in the treatment of FED such as deep lamellar endothelial
keratoplasty (DLEK) and Descemet's stripping with endothelial
Glaucoma is a group of diseases
of the optic nerve involving loss of retinal ganglion cells in
a characteristic pattern of optic neuropathy. Although raised
intraocular pressure is a significant risk factor for developing
glaucoma, there is no set threshold for intraocular pressure that
Hyperopia (Farsightedness) is
a defect of vision caused by an imperfection in the eye (often
when the eyeball is too short or when the lens cannot become round
enough), causing inability to focus on near objects, and in extreme
cases causing the inability to focus on objects
at any distance.
Keratoconus is a degenerative
non-inflammatory disorder of the eye in which structural changes
within the cornea cause it to thin and change to a more conical
shape than its normal gradual curve.
Macular Degeneration is a medical condition predominantly found in
elderly adults in which the center of the inner lining of the
eye, known as the macula area of the retina, suffers thinning,
atrophy, and in some cases, bleeding. This can result in loss
of central vision, which entails inability to see fine details,
to read, or to recognize faces.
Macular Holes is a small break
in the macula, located in the center of the eye's light-sensitive
tissue called the retina. The macula provides the sharp, central
vision we need for reading, driving, and seeing fine detail.
Myopia (Nearsightedness) is a
refractive defect of the eye in which collimated light produces
image focus in front of the retina when accommodation is relaxed.
Those with myopia see nearby objects clearly but distant objects
Nystagmus, is involuntary eye
movement that can be part of the vestibulo-ocular reflex (VOR)
or it can be part of a pathological process. It is characterized
by oscillations that may occur in the vertical, horizontal or
torsional planes, or in any combination.
Ocular Hypertension is intraocular
pressure (IOP) higher than normal in the absence of optic nerve
damage or visual field loss. Elevated IOP is the most important
risk factor for glaucoma, so those with ocular hypertension are
frequently considered to have a greater chance of developing the
Ocular Migraine (Acephalgic Migraine) is
a variant of migraine in which the patient may experience aura
symptoms such as scintillating scotoma, nausea, photophobia, hemiparesis
and other migraine symptoms but does not experience headache.
Photophobia (Light Sensitivity) is
usually due to too much light entering the eye, which causes over
stimulation of the photoreceptors in the retina and subsequent
excessive electric impulses to the optic nerve. This leads to
a reflex aversion to light, and discomfort or pain.
Pinguecula is a type of conjunctival
degeneration in the eye. It is extremely common and is seen as
a yellow-white deposit on the conjunctiva adjacent to the limbus
(the junction between the cornea and sclera).
Presbyopia describes the condition
where the eye exhibits a progressively diminished ability to focus
on near objects with age.
Ptosis (Drooping Eyelid) is an
abnormally low position (drooping) of the upper eyelid, a condition
that is addressed through plastic
surgery of the eyelids.
Pterygium is a wedge shaped
area of fibrosis, that appears to grow into the cornea. t is
associated with, and thought to be caused by ultraviolet-light
exposure (e.g. sunlight), low humidity, and dust.
Retinal Detachment is a disorder
of the eye in which the retina peels away from its underlying
layer of support tissue. Initial detachment may be localized,
but without rapid treatment the entire retina may detach, leading
to vision loss and blindness. It is a medical emergency.
Retinitis Pigmentosa (RP) is a
group of inherited disorders in which abnormalities of the photoreceptors
(rods and cones) or the retinal pigment epithelium (RPE) of the
retina lead to progressive visual loss.
Uveitis specifically refers to
inflammation of the middle layer of the eye, termed the "uvea" but
in common usage may refer to any inflammatory process involving
the interior of the eye. Uveitis requires an immediate thorough
examination by an ophthalmologist, along with urgent treatment
to control the inflammation.
