A cataract is a cloudy area in the lens in the front of the eye. There is no pain associated with the condition but there are other symptoms, including:
Most people develop cataracts simply as a result of aging, with the majority of cases occurring in people over the age of 55. Over 1.2 million Americans are diagnosed with cataracts each year. Other risk factors include eye injury or disease, a family history of cataracts, smoking or use of certain medications.
For people who are significantly affected by cataracts, lens replacement surgery may be recommended. During cataract replacement, the most common surgical procedure in the country, the lens is removed and replaced with an artificial one called an intraocular lens (IOL).
Patients with diabetes are at an increased risk of developing eye diseases that can cause vision loss and blindness, such as diabetic retinopathy, cataracts and glaucoma. These and other serious conditions often develop without vision loss or pain, so significant damage may be done to the eyes by the time the patient notices any symptoms. For this reason it is very important for diabetic patients to have their eyes examined once a year. Diagnosing and treating eye disease early can prevent vision loss. It is also important to maintain a steady blood-sugar level, take prescribed medications, follow a healthy diet, exercise regularly and avoid smoking.
Dry eye occurs when the eyes aren't sufficiently moisturized, leading to itching, redness and pain from dry spots on the surface of the eye. The eyes may become dry and irritated because the tear ducts don't produce enough tears, or because the tears themselves have a chemical imbalance.
People usually begin experiencing dry eye symptoms as they age, but the condition can also result from certain medications, conditions or injuries.
Dry eye is not only painful, it can also damage the eye's tissues and impair vision. Fortunately, many treatment options are available.
Non-surgical treatments for dry eye include blinking exercises, increasing humidity at home or work, and use of artificial tears or moisturizing ointment. If these methods fail, small punctal plugs may be inserted in the corners of the eyes to limit tear drainage, or the drainage tubes in the eyes may be surgically closed. Eyelid surgery is also a solution if an eyelid condition is causing your dry eyes.
Glaucoma is a leading cause of blindness in the U.S. It occurs when the pressure inside the eye rises, damaging the optic nerve and causing vision loss. The condition often develops over many years without causing pain or other noticeable symptoms - so you may not experience vision loss until the disease has progressed.
Sometimes symptoms do occur. They may include:
People at high risk include those who are over the age of 40, diabetic, near-sighted, African-American, or who have a family history of glaucoma.
To detect glaucoma, your physician will test your visual acuity and visual field as well as the pressure in your eye. Our doctors use the Stratus Ocular Coherence Tomograph™ (OCT) by Zeiss to reveal any damage as early as possible. Regular eye exams help to monitor the changes in your eyesight and to determine whether you may develop glaucoma.
Once diagnosed, glaucoma can be controlled and further vision loss can be prevented. Treatments to lower pressure in the eye include non-surgical methods such as prescription eye drops and medications, laser therapy, and surgery.
Conjunctivitis, more commonly known as pink eye, is an infection and inflammation of the conjunctiva, the membrane that lines the eyelid and eyeball. The inflammation affects the blood vessels and gives the eye a pink or red appearance.
Pink eye is caused by a bacterial or viral infection and can be contagious, so diagnosis and proper treatment are important. It can also be caused by an allergic reaction or a foreign object in the eye. Symptoms of pink eye include redness and itchiness in one or both eyes, along with a discharge that may turn into a crust overnight. Excess tearing can also occur.
Treatment for pink eye depends on the cause. Your doctor may prescribe antibiotic eye drops or recommend over-the-counter drugs.
The macula is a part of the retina in the back of the eye that ensures that our central vision is clear and sharp. Age-related macular degeneration (AMD) occurs when the arteries that nourish the retina harden. Deprived of nutrients, the retinal tissues begin to weaken and die, causing vision loss. Patients may experience anything from a blurry, gray or distorted area to a blind spot in the center of vision.
AMD is the number-one cause of vision loss in the U.S. Macular degeneration doesn't cause total blindness because it doesn't affect the peripheral vision. Possible risk factors include genetics, age, diet, smoking and sunlight exposure. Regular eye exams are highly recommended to detect macular degeneration early and prevent permanent vision loss. In our practice, detection of macular degeneration involves the laser Stratus OCT by Zeiss, which takes precise cross-sectional images of the retina.
Symptoms of macular degeneration include:
There are two kinds of AMD: wet (neovascular/exudative) and dry (non-neovascular). About 10-15% of people with AMD have the wet form. "Neovascular" means "new vessels." Accordingly, wet AMD occurs when new blood vessels grow into the retina as the eye attempts to compensate for the blocked arteries. These new vessels are very fragile, and often leak blood and fluid between the layers of the retina. Not only does this leakage distort vision, but when the blood dries, scar tissue forms on the retina as well. This creates a dark spot in the patient's vision.
Dry AMD is much more common than wet AMD. Patients with this type of macular degeneration do not experience new vessel growth. Instead, symptoms include thinning of the retina, loss of retinal pigment and the formation of small, round particles inside the retina called drusen. Vision loss with dry AMD is slower and often less severe than with wet AMD.
Recent developments in ophthalmology allow doctors to treat many patients with early-stage AMD with the help of lasers and medication.
