Medical Eye Examinations
Medical eye examinations should be a regular part of every person's healthcare routine. Not only do we test vision and provide prescriptions for eyeglasses and contact lenses when necessary, but we use state-of-the-art equipment and techniques to assess and service your overall eye health. A regular exam encompasses comprehensive testing for the early detection of a range of eye problems if any eye health issues are detected, an individualized treatment program will be designed to correct the problem or prevent it from progressing.
At Vistasite we diagnose and treat most vision and eye disorders. Most common conditions are described below for your reference.
Age Related Macular Degeneration (ARMD)
Age Related Macular Degeneration is currently a leading cause of blindness in the United States among Caucasian population. This retinal disease affects central vision that is responsible for fine, detailed vision reading, driving watching TV, there are two main types of ARMD. Dry, which is more common and less aggressive form of the disease currently treated by eye vitamins. Wet ARMD which is more likely to cause severe visual impairment. Only recently a viable treatment for this condition has become available in the U.S. called Lucentis, an inject-able preparation that not only stabilizes the disease but also improves vision in many cases.
Amblyopia is reduced vision in one or both eyes, although it is not a very common vision disorder (it affects only 5% of total population), it is important to diagnose early. If detected early enough most amblyopic patients can be successfully treated. Having your child examined by an eye care professional is the only way to determine if amblyopia is present.
Astigmatism is a refractive error when light rays fail to focus in a single place on the retina. An astigmatic eye is commonly being described as being shaped like a football, instead of basketball. Even small amounts of astigmatism can cause night vision problems, glare, headaches, distortions, computer vision syndrome and tearing.
Blepharitis is a fairly common eye disease that affects outer edges of the lids where eyelashes originate. It can be caused by a number of infectious micro-organisms, but in most cases is related to seborrhea. (a common skin condition) Some of the symptoms include crusty, thickened, inflamed eyelids, itchy and scaly skin. Treatment is directed at physical removal of all the crust with lid scrubs, warm compresses and in more severe cases antibiotics.
Computer Vision Syndrome (CVS)
Computer Vision Syndrome is a collection of eye and vision-related problems, associated with computer use. Most common symptoms of CVS include eyestrain, headache, blurred vision, difficulty in changing the focus of the eyes, glare sensitivity, eye irritation, contact lens discomfort, neck, shoulder and back pain.
Convergence problems often result from inability of the eye muscles to work together. Constant or intermittent double vision, coping problems, skipping lines during reading, headaches, tiredness and falling asleep during computer work are some of the most common symptoms of this binocular disorder. It can be treated with special eyeglasses or vision therapy.
Conjunctivitis, commonly known as pink eye is an inflammation of the outside mucus membranes of the eye. There are four main types of conjunctivitis, depending on the etiology: Viral, bacterial, allergic and chemical. Treatment depends on the underlying etiology and removal of the irritant. Sometimes conjunctivitis can be very contagious. In order to prevent it from spreading patients are advised to frequently wash their hands, not to share towels, cosmetics or eye drops and to promptly seek treatment.
Dry eyes is a fairly common ocular condition that results in poor corneal wetness and, consequently compromised ocular health. Some of the symptoms include burning, redness, irritation, increased light sensitivity, blurry vision and even headaches. Different types of artificial tears are used to restore different layers of tear film. Our doctors of optometry will advise you on a moisturizing eye drop for your type of dry eye. More advanced and severe dry eye can also be treated with Restasis. Sometimes dry eye could be a sign of a systemic problem such as Arthritis, Diabetes, thyroid dysfunction or other conditions. Our doctors will advise you if you need further medical evaluation to determine the cause of your dry eye condition.
Diabetic Retinopathy is a disease that affects small blood vessels in the retina causing them to bleed, swell and decrease amount of oxygen to the retina. In early stages Diabetic Retinopathy may cause blurry vision, or it may not produce any visual symptoms at all. As the disease progresses patient will notice cloudy vision, floaters and flashes. If left untreated Diabetic Retinopathy may lead to blindness. To diagnose, an optometrist will dilate your eye and examine retina with special lenses and microscopes; you may benefit from laser treatment that will slow down progression of the disease. All patients with diabetes should have a dilated eye exam at least one a year.
Floaters are spots, clouds or cobwebs moving in the field of vision, clumps of gel inside the vitreous body (a gel like substance that fills the inner eye). As we age the vitreous gel may shrink and form clumps and strands inside the eye causing floaters, the gel may also pull away or separate from the retina causing posterior vitreous detachment. When vitreous gel pulls on or rubs the retina you may experience flashes or streaks of lights. In more serious cases shrinking or pulling of the vitreous gel can lead to retinal tear, a true medical emergency which in turn may cause retinal detachment.
Glaucoma is a disease in which the pressure in the eye increases and damages optic nerve. If left untreated damage to the optic nerve can result in severe vision loss, even blindness. Glaucoma is one of the leading causes of blindness; cases increase with age. People with family history of Glaucoma, African Americans and very nearsighted are at higher risk of developing disease.Most common type, primary open angle Glaucoma develops gradually, painlessly and usually without any symptoms. Narrow angle Glaucoma is more rare and sometimes occurs rapidly with symptoms of ocular pain, headache, nausea, loss of vision and redness. If diagnosed and treated early it can be controlled, our doctors of optometry will examine you for signs of Glaucoma by checking your eye pressure, they will also examine your optic nerves and may perform Pachymetry, visual field and GDx examination. Treatment of Glaucoma includes eye drops and in some cases laser treatment or surgery.
Hyperopia occurs when distant objects are seen more clearly than objects at near. Even though small amounts of Hyperopia can easily go undetected, it can still result in headaches, eyestrain, heavy eyes, tearing, intermittent blurry vision, computer vision syndrome and glare. Our eye doctors are trained to detect even smallest amount of Hyperopia with special objective techniques.
Keratoconus is a congenital anomaly of the cornea in which it's central part becomes thinner and protrudes forward in a cone shaped manner, usually starting at puberty and affects both eyes. Correction and treatment is best achieved by fitting the patient with rigid gas permeable lenses. Presently some corneal specialists advocate the use of Intacs, a procedure in which a corneal ring stabilizes and flattens bulging cornea. In severe cases of the condition where conservative treatment fails a corneal transplantation is performed.
Myopia occurs when light rays that enter the eye through the pupil focus before the retina. People with myopia have difficulty seeing objects at a distance. If myopia is low to moderate, vision up close is often very good even without glasses.
Strabismus occurs when one or both eyes turn in or out either sometimes or all the time. In Strabismus, signals traveling from the brain to the eye and between the eyes is malfunctioning. Since eyes are pointing in different directions, one image is suppressed, because this is painless the patient may not be aware that it is happening. There are however, some organic causes of eye turn and they must be addressed immediately they may be a sign of impending stroke, tumor or aneurysm.
