The Doctors at Clear Lake Eye Center provide comprehensive eye examinations in a comfortable and calm environment utilizing state-of-the-art diagnostic equipment. The examination includes a vision check and eye health check.
Your Eye Exam at Clear Lake Eye Center
The vision check includes measuring the visual acuity at both distance and near, measuring the power of the eyes with a test called a refraction. The testing includes eye muscle balance testing and test for measuring the focusing ability of the eyes. It is important for the eyes to team well together and to focus from near distance to far distance and back again.
As many of our day to day tasks require these abilities. Students, in particular, need to be able to focus on the overhead in a classroom and then at their paper while taking notes. While looking at distance the eyes must be able to see, when looking at near the eyes turn in slightly and the lens refocuses on near task. The pupil also becomes slightly smaller when looking at objects at near. If the eyes don’t team well or the focusing is sluggish copying from distance to near can become difficult.
Eye exercises can be prescribed to help improve the focus and/or eye teaming skills. Around the age of 40 years we lose the ability to focus our eyes on near objects (when distance vision is corrected). This is called Presbyopia. This is a normal and unwelcome change which happens to everyone. Special glasses can be prescribed to help with focusing on near objects while still being able to see far away.
Our eye exams include testing for glaucoma, macular degeneration, diabetes, dry eye, blepharitis and color vision deficits, cataracts as well as many other eye conditions. Some conditions require follow-up visits for further testing and monitoring.
Glaucoma is a disease of the optic nerve. Generally, there are no symptoms until it is in the later stages. When glaucoma is diagnosed it can be treated with medication to lower the pressure of the eye. Monitoring in also mandatory in the treatment of glaucoma.
Macular degeneration has two forms. One is a dry form which is generally slowly progressive and the other is the wet form, which can cause immediate vision loss if not caught. The good news is both forms of age-related macular degeneration can be treated if caught in time.
Diabetes and Your Eye
Diabetes is a condition that affects the whole body including the eye. Diabetes can cause changes in eye muscle function, cataracts, optic nerve and retina. It is important for diabetic patients to maintain proper diabetic control to help prevent vision loss or changes.
Additionally, it is important for diabetic patients to be aware of their glucose levels and HbA1c. This information helps the doctors when examining the eye health. After the eye examination our doctors will also send a report to the patient’s physician regarding the eye health pertaining to diabetes.
Dry eye can affect both vision and comfort of the eyes. There are different causes of dry eye and treatments for dry eye. Symptoms include redness, itchiness, blurred vision, scratchiness (a foreign body sensation), and burning. Treatment depends on the type and severity of the dry eye.
Blepharitis is a condition of the eyelids. There are different types of blepharitis and treatment depends on the type and severity of the condition. Blepharitis can exasperate dry eye and can also cause styes on the eyelid margins.
Color Vision Exam
Color vision is also tested. If a person has a color vision deficit it may become difficult to perform certain tasks. Therefore, it is important to know if you have a deficit before deciding on a particular career. Color vision can change in certain eye health conditions as well.
Cataracts are caused by a clouding of the lens of the eye. While this is a normal aging response it can be accelerated by a lifetime ultra violet exposure, prolonged use of certain medications such as steroids, trauma, disease, and family history of developing cataracts early in life. Cataracts are very common and are monitored until the vision can no longer be corrected as well as the patient would like to be able to see.
Cataract surgery is generally done on an out-patient basis. A very small incision is made at the top of the colored part of the eye by the cataract surgeon. The cataract is then removed and an implant is placed into the eye. After the cataract surgery the patient is monitored closely by the surgeon and the optometrist for proper healing. The patient immediately sees better and many times color vision is also better.
Eye examinations are very comprehensive and can lead to discovery of other health conditions of which the patient is not aware they have. These conditions include heart/cholesterol issues, diabetes, and multiple sclerosis as well as other conditions. We recommend getting an eye examination on a yearly basis not just for changes is vision but also for changes in eye health.
