Common eye problems

  1. 1. Common Eye ProblemsThe eye, like most all other parts of the body, is subject to a variety of conditions that fall underthe 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 inthe eye(s), each part of the eye is subject to each of these categories of problems and, manytimes, several parts of the eye(s) are involved. For example, pink eye (conjunctivitis) is an eyeinfection, 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 tosensitivity to the contact lens solution. A corneal abrasion (scratch of the cornea) is the result ofinjury 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 innereyelid, it is…
  2. 2. A cataract is any clouding of the human lens. This clouding can cause a reduction in vision. The lens iscomposed of protein and water structured to allow light to clearly pass through. Changes to thestructure of the protein result in a cataract. The changes in vision associated with a cataract dependupon which part of the lens is affected.Pink Eye (Conjunctivitis) Pink eye (conjunctivitis) is an inflammation of the tissue on the surfaceof the eye and/or the inside lining of the eyelids.Contact Lens Solution Toxicity Contact lens solution toxicity refers to those conditions in theeye that are the result of an unwanted reaction to the use of such solutions.
  3. 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 theback 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 astye.Both the meibomian and sebaceous oil glands of the lid can be involved in this process, which beginswith a blockage of the normal openings of these glands, leading to the swelling. Typically, there isbacterial contamination.
  4. 4. Presbyopia Presbyopia is an age-related change in vision whereby one loses the ability to seenear without corrective lenses or corrective surgery. The cause of presbyopia is a change in theability of the human lens to change…Corneal Foreign Body A corneal foreign body occurs when the cornea has a piece of foreignmatter lodged in it. The most common types of foreign bodies include particles of dust, debris(eg, metal, wood), paint chips, and plant materials.
  5. 5. TREATMENTS AND DRUGSBlepharitisTreatment 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.CATARACTA 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. Cloudedvision caused by cataracts can make it more difficult to read, drive a car — especially at night —or see the expression on a friends face.Most cataracts develop slowly and dont disturb your eyesight early on. But with time, cataractswill eventually interfere with your vision.At first, stronger lighting and eyeglasses can help you deal with cataracts. But if impaired visioninterferes with your usual activities, you might need cataract surgery. Fortunately, cataractsurgery is generally a safe, effective procedure.Pink eye (conjunctivitis)
  6. 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 bloodvessels in the conjunctiva to become more prominent, which is what causes the pink or red castto the whites of your eyes.The cause of pink eye is commonly a bacterial or viral infection, an allergic reaction or — inbabies — an incompletely opened tear duct.Though the inflammation of pink eye can be irritating, it rarely affects your vision. If you suspectpink 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 AbrasionEctropion (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 occursmainly in older adults. In severe ectropion, the entire length of the eyelid is turned out. Whenectropion 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 tocorrect the condition.EYE FLOATERSEye floaters are spots in your vision. Eye floaters may look like black or gray specks, strings orcobwebs 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 withinthe vitreous tend to clump together and can cast tiny shadows on your retina, which you may seeas eye floaters.If you notice a sudden increase in the number of eye floaters, contact an eye specialistimmediately — especially if you also see flashes of light or lose your peripheral vision. Thesecan be symptoms of an emergency that requires prompt attention.STYEA sty (hordeolum) is a red, painful lump near the edge of your eyelid that may look like a boil ora pimple. Sties are often filled with pus. A sty usually forms on the outside of your eyelid, butsometimes 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 maybe able to relieve the pain or discomfort of a sty by applying a warm washcloth to your eyelid.
  7. 7. PRESBYOPIAPresbyopia is the gradual loss of your eyes ability to focus actively on nearby objects. Its anatural, often annoying part of aging that usually becomes noticeable in your early to mid-40sand continues to worsen until around age 65.You may become aware of presbyopia when you start holding books and newspapers at armslength to be able to read them. If youre nearsighted, you might temporarily manage presbyopiaby reading without your glasses.A basic eye exam can confirm presbyopia. You can correct the condition with nonprescriptionreading glasses or prescription eyeglasses or contact lenses. Surgery also may be an option forpresbyopia.Dry eyes occur when your tears arent able to provide adequate moisture for your eyes. Tears canbe inadequate for many reasons. For example, dry eyes may occur if you dont produce enoughtears or if you produce poor-quality tears.DRY EYESDry eyes feel uncomfortable. If you have dry eyes, your eyes may sting or burn. You mayexperience dry eyes in certain situations, such as on an airplane, in an air-conditioned room orafter looking at a computer screen for a few hours.Dry eyes treatments may make you more comfortable. Dry eyes treatments can include lifestylechanges and eyedrops. For more serious cases of dry eyes, surgery may be an option.
