Primary eye care includes a comprehensive vision and eye health examination. This examination is designed to detect a wide range of problems affecting vision function, such as blurred vision or eye discomfort. A comprehensive eye and vision examination may include, but it not limited to the following:
- A review of your personal and family health history and any history of eye problems.
- Evaluation of your distance and near vision with an eye chart.
- Evaluation of the presence of nearsightedness, farsightedness, astigmatism and presbyopia.
- Near vision testing to determine if you have presbyopia and need progressive lenses or bifocals.
- Evaluation of your eyes’ ability to work together as a team.
- An eye pressure test and examination of the optic nerve to rule out glaucoma.
- Examination of the interior of your eyes to rule out other eye problems, such as cataracts and macular degeneration.
- Other tests may include a Color Blindness Test, a Vision Field Test, a dilated pupil exam or any other specialized tests that the doctor feels necessary.
At our office we incorporate computerized technology to assist the evaluation of spectacle prescriptions, peripheral vision, intraocular pressure and eye health. Computerized examination instruments are used to supplement rather than replace personalized care. If you have diabetes, high blood pressure, heart disease, arthritis, elevated cholesterol or thyroid disease, your vision and the health of your eyes could be affected. Also, certain medications can cause visual problems, which is why it’s so important to have your eyes examined on a regular basis. The American Optometric Association recommends that all people should have a comprehensive eye examination every one to two years depending on one’s particular needs.
Prior to a contact lens examination a complete medical and refractive eye examination is necessary. This exam is critical to assure the good health of your eyes and to rule out the possibility of any unsuspected, underlying condition that may prevent contact lens use. A contact lens evaluation involves both a consultation and eye measurements.
The doctor measures the shape and contour of your corneas; in addition she looks at tear production and tear quality as well. Your doctor will evaluate your eyes and determine which type of contact lens will best suit your individual needs. Lens complexity plays an important part of the decision. The need for bifocals, astigmatism or binocular eye coordination issues need to be considered.
We require training sessions for new contact lens wearers and offer it to those wanting a refresher course. While it is not difficult, putting a contact lens into your eyes for the first time can be a challenge for some people. We provide training to help you become comfortable with this process, lens hygiene guidelines are also outlined at this time. Insertion and Removal Training sessions are provided one on one with an optician lasting from 30 minutes to 1 hour. If additional time is needed, it will be necessary to schedule a second 30 minute training session at a different time. Upon completion of successful insertion and removal, the patient may take their contact lenses home and begin wearing them.
We will then schedule the first follow-up appointment with the doctor.Contact lenses are prescription medical devices that expire after one year (or sooner if the doctor determines a medical reason for a shorter expiration date). To make sure your eyes and vision stay healthy while wearing contact lenses, please follow the guidelines set by your doctor. Oftentimes, your lenses will still feel good even when you are over-wearing them. Do not wear your lenses overnight unless they are approved for extended wear and your doctor has discussed this with you.
We provide diagnosis, treatment and management of diseases which affect the human eye and visual system. Some examples include:
Cataract is a clouding or opacity of the natural internal lens of the eye. This opacity may be a small spot or may cover the entire lens. When light enters the eye it is scattered, causing images to appear hazy and blurred. There are many different types of cataracts. Ultimately, the best treatment is to remove the cataract lens and replace it with an acrylic man-made lens. This is referred to as cataract surgery.
Macular Degeneration is a condition in which the central part of the back of the eye loses blood circulation. It is considered a natural aging process. There is a breakdown of retinal pigment epithelium cells in the macular region. As the disease progresses, central vision diminishes. It is believed that this breakdown may be due to a lack of nutrients being supplied to the region. Additional studies have found a genetic link to this disease. Treatment can include better nutritional management, sometimes to include a tablet containing the primary minerals and vitamins that are found lacking in many macular degenerated patients.
Glaucoma occurs when the pressure inside of the eye increases to the point where it damages the sensitive retinal nerves that line the back of the eye. There are a multitude of tests that we provide to evaluate the possibility of Glaucoma. For example, the light color found here, in the center of the optic nerve head, is a classic observation found in Glaucoma. Other tests include evaluation of the Nerve Fiber thickness around the optic nerve. Threshold Field tests are also very important in the ongoing evaluations needed to monitor the treatment program which most frequently includes the selection of the most appropriate eye medication.
Dry Eye Syndrome is a condition in which there are insufficient tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. People with dry eyes either do not produce enough tears or have a poor quality of tears. Symptoms include scratchy eyes, burning, mild redness and gritty feeling eyes. Oral medications, reading, computer tasks and dry environments may aggravate marginally dry eyes. You can relieve the symptoms, but not cure the original cause. Treatment may include artificial tears; eye drops for treating allergies; and/or punctual plugs inserted in the tear drainage canals.
Diabetic Retinopathy is a condition where sugar levels start a series of events which end in damaged blood vessel walls. As such, the blood vessels begin to leak fluid or bleed, resulting in hemorrhages and swelling followed by the formation of yellow deposits known as exudates. Vision can be lost where some of these hemorrhages and exudative spots occur. The best treatment is to have a yearly eye examination to identify if these spots are present. We carefully examine the back of your eyes and provide you with the results and additionally offer these to other physicians for a multidisciplinary treatment program.
