Dry eye is a common eye condition relating to the tear film that coats and lubricates the outer layer of the eye. This protective tear film is composed of mucus, water, and oil. If this film diminishes – due to natural aging, disease, smoking, or environmental conditions – the eyes can feel dry, red, and irritated. Ironically, many people who suffer from dry eye complain of excess tearing, as the eyes seek to compensate for the dryness. Dry eye can be effectively treated with artificial tears, medications, or, in some cases, plugs to block the tear duct drains, allowing one’s natural tears to be more effective.
A cataract is a clouding of the natural, crystalline lens of the eye. This is a natural process associated with aging. Over time, the lens may become so cloudy that it can no longer clearly transmit or focus light. At that point, cataract surgery may be necessary to remove the impaired lens and replace it with an artificial, intraocular lens (IOL).
In glaucoma, the optic nerve that connects the eye to the brain is damaged by excessive – and usually unfelt, high-fluid – pressure in the eye. If left untreated, this nerve damage can lead to blindness. Glaucoma is manageable with regular eye exams and with drops or surgical treatment to lower the pressure in the eye. Glaucoma screening is one of the main reasons to have regular eye examinations.
Amblyopia, or “lazy eye” is a condition in which the eye loses visual ability, or never develops it, due to insufficient use during childhood. This condition has a number of causes, including crossed eyes or a poor visual image in one eye. If caught early, it can be treated with glasses, medication, eye exercises, an eye patch, or surgery.
Macular degeneration—also called age-related macular degeneration—is an eye disease that gradually destroys central vision. It is caused by breakdown of the macula (a tiny part of the retina). The disease can take many forms. Symptoms include blurred vision, seeing wavy lines where straight lines actually exist, impaired color vision, and difficulty seeing details (whether close-up or far away). Macular generation can ultimately lead to blindness if left untreated. Newer forms of therapy are effective in the early stages of the disease.
Diabetic Retinopathy is a condition in which the retina of the eye is affected by diabetes. The disease causes blood vessels in the eye to leak blood or serum, which can result in swelling of the retina and reduced vision. There can also be lack of blood flow to parts of the retina that may lead to new, fragile vessel growth in the retina and to retinal hemorrhages.
Blepharitis is an inflammation of the eyelids. A person with this condition may suffer chronic inflammation causing burning, itching, or a foreign body sensation in the eye. Blepharitis can be caused by bacteria, dandruff, or a reaction to the patient’s own oil glands, and it is commonly treated with careful cleaning and attention to eyelid hygiene. Prescribed topical medications are also useful.
More commonly referred to as a stye, a chalazion is a small, swollen lump on the eyelid caused by a blockage or inflammation of one of the oil producing glands. If not serious, this condition can sometimes be treated at home with warm compresses and gentle lid massage. However, serious or recurring chalazia may require medical attention, including drainage or antibiotics.
Corneal Refractive Therapy (CRT) makes use of oxygen permeable contact lenses worn at night to temporarily reshape the cornea of the eye while the patient sleeps. CRT allows patients to see clearly during their daytime activities without need for glasses, contacts, or surgery.
A torn or detached retina is a serious medical condition that requires immediate medical intervention to avoid vision loss or blindness. The retina is the light-sensing nerve membrane at the back of the eye. This membrane can become torn or detached for a number of reasons, including trauma to the head or eye, nearsightedness, a family history of the condition, or diabetes. Sometimes the condition occurs spontaneously. Often there are warning signs of new flashes and/or floaters. Early intervention with office laser treatment of a torn retina may prevent the need for surgery, which is typically used to treat a detached retina.
In ectropion of the lower eyelid, the lid has turned or rolled downwards and outwards, away from the eye. Aging is the most frequent cause of this condition, followed, less frequently, by scar tissue, paralysis of facial nerves (Bells Palsy), or congenital birth defects. Common symptoms associated with this condition include dryness, eye irritation, excessive tearing, redness, and sensitivity to light. Surgery to correct the eyelid is usually indicated and highly successful.
In entropion of the lower eyelid, the lid has rolled inwards towards the eye. Again, this condition is most frequently caused by aging, although other factors such as infection or scarring on the eyelid can also cause it. The inward rolled lid and lashes rub against the eye, causing irritation, redness, and heightened sensitivity to light. If the irritation continues, ulceration of the eye surface can result. Eyelid surgery is generally required to correct the problem.
The vitreous humor is the clear gel that fills the large central cavity of the eye in front of the retina. It is composed of water and fibrous proteins that give it a gelatin-like consistency. Floaters are small, shadowy specks floating in a person’s field of vision. These are generally clumps of protein or condensed gel that have shifted and are casting shadows on the retina. Floaters are common in the aging or nearsighted eye and are not generally a problem by themselves. However, if a person experiences a sudden onset of floaters accompanied by light flashes or any vision loss, this could indicate a more serious retinal problem and should be checked immediately by an eye doctor.
Headaches may be caused by various eye conditions. Ocular migraines are the most common headaches associated with the eyes. Ocular migraines are visual disturbances characterized by light flashes or visual images that look gray or have a wavy appearance. Other symptoms are loss of vision, particularly in one eye, and increased sensitivity to bright lights. If an ocular migraine is accompanied by a common migraine, the visual disturbances happen before the onset of headache symptoms. Headaches may also be caused by eye fatigue and excessive focusing due to a need for a change in glasses. Glaucoma and neurologic diseases are other possible ocular causes of headaches.
Lacrimal obstruction simply means blocked tear ducts. In congenital lacrimal obstruction, a child’s tear ducts are blocked – usually as a result of a membrane covering the base of the tear duct – and tears that lubricate the eyes are unable to drain out the duct and down the nasal passage. This can cause infection and painful swelling if not treated. Treatment for blocked tear ducts includes massage of the duct, drops or ointment, and probing and irrigation to open the blockage. Acquired obstruction can occur from infections or inflammation of the nasolacrimal duct system.
LASIK (Laser Assisted In-Situ Keratomileusis) is a laser eye procedure performed to correct nearsightedness, farsightedness, and astigmatism. During the procedure, a thin, protective flap is first created in the outer layer of the cornea. Next, the excimer laser is used to reshape the corneal tissue beneath the flap, and then the flap is repositioned without need for stitches. LASIK usually results in quick recovery times for patients and excellent visual results. Some conditions preclude having LASIK and, therefore, screening technologies such as topography and corneal thickness measurements are important to obtain prior to having the procedure.
A patient with low vision has experienced vision loss that cannot be corrected by glasses, contacts, or surgery. He or she, however, still has some usable vision. A number of conditions can cause low vision, including birth defect, cataracts, injury, or diseases such as glaucoma, diabetic retinopathy, and macular degeneration. There are a number of strategies and vision aids that can help people with low vision continue to enjoy the activities they love. Newer types of magnifiers and telescopic lenses may allow patients to read, watch television, write checks, and perform other daily tasks.
Ptosis refers to a condition in which the upper eyelid droops, covering part of the eye. Acquired ptosis occurs when the eyelid’s levator tendon becomes loosened or completely detached. This can be caused by natural aging, injury, or nerve malfunction. Typically, outpatient eyelid surgery is required to reattach the tendon and tighten the muscles to reposition the lid correctly.
Sometimes, ptosis (drooping eyelids) can be present from birth, or develop within the child’s first year. In these cases, the problem is generally due to an abnormality in the development of the levator muscle that elevates the upper lid. Three-quarters of the time, it affects only one eye. Again, surgery is the primary treatment for congenital ptosis.
Skin cancer can affect the skin on the eyelid or the surrounding face. Frequently, it develops on the lower eyelids, but it can occur in any area surrounding the eye. Skin cancer on the eyelid can take the form of painless raised nodules, or there may be ulcerated, bleeding, or crusted areas. Any abnormal growth or change to the eyelid area needs to be seen immediately by an ophthalmologist for proper diagnosis and treatment.
Strabismus, or crossed eyes, is a condition in which the eyes are unable to work in alignment. One or both eyes may turn in, out, or up, either constantly or intermittently. This condition is commonly diagnosed early in childhood. Medical intervention – including glasses, medication, prisms, and possibly surgery – are necessary to correct this problem, particularly to ensure that amblyopia (lazy eye) does not develop.
Uveitis is an inflammation of the uvea, which is the pigmented layer in the eye. It includes the iris (the colored part of the eye one normally sees), the choroid (a layer that nourishes the retina with blood), and the ciliary body (the area that both creates the aqueous humor and controls the shape of the lens, changing the eye’s focal point). An infection in any part of the uveal tract is serious and, because of the rich blood supply leading to this area, could also point to disease elsewhere in the body. Symptoms generally include severe light sensitivity.
In a percentage of cataract surgery patients (most studies report between 20 and 30 percent), the patient’s original lens capsule, the back portion of which is left in place to help position the artificial intraocular lens (IOL), can become clouded with fibrous growth. This can happen weeks or even years after surgery. This condition is easily treated with a YAG Capsulotomy, an in-office procedure in which a laser beam is used to create an opening in the capsule, reducing the clouding and allowing light to enter. The painless procedure takes only a few minutes, and patients can return to their normal activities almost immediately afterwards.
