1. Common Eye Problems
The eye, like most all other parts of the body, is subject to a variety of conditions that fall under
the following categories: infection (eg, caused by bacteria, viruses, and fungi), inflammation,
injury (trauma), heredity, aging changes, and degeneration.
While most of us during our lifetime may only suffer from a mild infection or inflammation in
the eye(s), each part of the eye is subject to each of these categories of problems and, many
times, several parts of the eye(s) are involved. For example, pink eye (conjunctivitis) is an eye
infection, usually caused by viruses, that is common in children but can affect people of all ages.
Contact lens wearers can get inflammation of the eye called contact lens solution toxicity due to
sensitivity to the contact lens solution. A corneal abrasion (scratch of the cornea) is the result of
injury to the cornea and, depending on the type of injury, may result in recurrent corneal erosion.
Blepharitis is an inflammatory condition that can affect the upper eyelid(s), the lower eyelid(s),
and even the conjunctiva (surface of the eye). Aging changes in the eye result in cataracts,
flashes and floaters, and presbyopia.
Blepharitis is inflammation of the eyelids. When it involves the outside front of the eyelid,
where the eyelashes are attached, it is called anterior blepharitis. If blepharitis involves the inner
eyelid, it is…

2. A cataract is any clouding of the human lens. This clouding can cause a reduction in vision. The lens is
composed of protein and water structured to allow light to clearly pass through. Changes to the
structure of the protein result in a cataract. The changes in vision associated with a cataract depend
upon which part of the lens is affected.
Pink Eye (Conjunctivitis) Pink eye (conjunctivitis) is an inflammation of the tissue on the surface
of the eye and/or the inside lining of the eyelids.
Contact Lens Solution Toxicity Contact lens solution toxicity refers to those conditions in the
eye that are the result of an unwanted reaction to the use of such solutions.

3. Corneal Abrasion A corneal abrasion is a scratch or cut (abrasion) of the clear outer layer
(cornea) of the eye. Injury (trauma) is the most common cause for corneal abrasions.
Flashes and Floaters Flashes and floaters describes a condition that comes from changes in the
back chamber of the eye (the posterior chamber, also known as the vitreous cavity).
StY (Hordeolum and Chalazion) is a local, acutely inflamed growth (swelling, lesion) of the eyelid.
They can occur at the lid margin or farther up the lid on either the inner (tarsal) side or the outer (skin)
side of the lid. A chalazion is the chronic form of a stye, and its cellular makeup is different than that of a
stye.
Both the meibomian and sebaceous oil glands of the lid can be involved in this process, which begins
with a blockage of the normal openings of these glands, leading to the swelling. Typically, there is
bacterial contamination.

4. Presbyopia Presbyopia is an age-related change in vision whereby one loses the ability to see
near without corrective lenses or corrective surgery. The cause of presbyopia is a change in the
ability of the human lens to change…
Corneal Foreign Body A corneal foreign body occurs when the cornea has a piece of foreign
matter lodged in it. The most common types of foreign bodies include particles of dust, debris
(eg, metal, wood), paint chips, and plant materials.

5. TREATMENTS AND DRUGS
Blepharitis
Treatment for blepharitis can include:
• Cleaning the affected area regularly. Cleaning your eyelids with a warm washcloth can
help control signs and symptoms. Self-care measures may be the only treatment
necessary for most cases of blepharitis.
• Antibiotics. Eyedrops containing antibiotics applied to your eyelids may help control
blepharitis caused by a bacterial infection. In certain cases, antibiotics are administered in
cream, ointment or pill form.
• Steroid eyedrops or ointments. Eyedrops or ointments containing steroids can help
control inflammation in your eyes and your eyelids.
• Artificial tears. Lubricating eyedrops or artificial tears, which are available over-the-
counter, may help relieve dry eyes.
• Treating underlying conditions. Blepharitis caused by seborrheic dermatitis, rosacea or
other diseases may be controlled by treating the underlying disease.
Blepharitis rarely disappears completely. Even with successful treatment, relapses are common.
CATARACT
A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts,
seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded
vision caused by cataracts can make it more difficult to read, drive a car — especially at night —
or see the expression on a friend's face.
Most cataracts develop slowly and don't disturb your eyesight early on. But with time, cataracts
will eventually interfere with your vision.
At first, stronger lighting and eyeglasses can help you deal with cataracts. But if impaired vision
interferes with your usual activities, you might need cataract surgery. Fortunately, cataract
surgery is generally a safe, effective procedure.
Pink eye (conjunctivitis)

6. Pink eye (conjunctivitis) is an inflammation or infection of the transparent membrane
(conjunctiva) that lines your eyelid and part of your eyeball. Inflammation causes small blood
vessels in the conjunctiva to become more prominent, which is what causes the pink or red cast
to the whites of your eyes.
The cause of pink eye is commonly a bacterial or viral infection, an allergic reaction or — in
babies — an incompletely opened tear duct.
Though the inflammation of pink eye can be irritating, it rarely affects your vision. If you suspect
pink eye, you can take steps to ease your discomfort. But because pink eye can be contagious,
early diagnosis and treatment is best to help limit its spread.
ECTROPION Corneal Abrasion
Ectropion (ek-TROH-pee-on) is a condition in which your eyelid — typically the lower lid —
turns out, leaving the inner eyelid surface exposed and prone to irritation. Ectropion occurs
mainly in older adults. In severe ectropion, the entire length of the eyelid is turned out. When
ectropion is less severe, only one segment of the eyelid sags away from the eye.
Artificial tears can help relieve the symptoms caused by ectropion until you can have surgery to
correct the condition.
EYE FLOATERS
Eye floaters are spots in your vision. Eye floaters may look like black or gray specks, strings or
cobwebs that drift about when you move your eyes.
Most eye floaters are caused by age-related changes that occur as the jelly-like substance
(vitreous) inside your eyes becomes more liquid. When this happens, microscopic fibers within
the vitreous tend to clump together and can cast tiny shadows on your retina, which you may see
as eye floaters.
If you notice a sudden increase in the number of eye floaters, contact an eye specialist
immediately — especially if you also see flashes of light or lose your peripheral vision. These
can be symptoms of an emergency that requires prompt attention.
STYE
A sty (hordeolum) is a red, painful lump near the edge of your eyelid that may look like a boil or
a pimple. Sties are often filled with pus. A sty usually forms on the outside of your eyelid, but
sometimes a sty can form on the inner part of your eyelid.
In most cases, a sty will begin to disappear on its own in a few days. In the meantime, you may
be able to relieve the pain or discomfort of a sty by applying a warm washcloth to your eyelid.

7. PRESBYOPIA
Presbyopia is the gradual loss of your eyes' ability to focus actively on nearby objects. It's a
natural, often annoying part of aging that usually becomes noticeable in your early to mid-40s
and continues to worsen until around age 65.
You may become aware of presbyopia when you start holding books and newspapers at arm's
length to be able to read them. If you're nearsighted, you might temporarily manage presbyopia
by reading without your glasses.
A basic eye exam can confirm presbyopia. You can correct the condition with nonprescription
reading glasses or prescription eyeglasses or contact lenses. Surgery also may be an option for
presbyopia.
Dry eyes occur when your tears aren't able to provide adequate moisture for your eyes. Tears can
be inadequate for many reasons. For example, dry eyes may occur if you don't produce enough
tears or if you produce poor-quality tears.
DRY EYES
Dry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn. You may
experience dry eyes in certain situations, such as on an airplane, in an air-conditioned room or
after looking at a computer screen for a few hours.
Dry eyes treatments may make you more comfortable. Dry eyes treatments can include lifestyle
changes and eyedrops. For more serious cases of dry eyes, surgery may be an option.
