At The Eye Clinic of Texas our doctors provide comprehensive eye exams for patients from throughout greater Houston in Galveston, Texas City & League City. A complete or comprehensive eye exam is a thorough examination of your eye health and vision. In addition to evaluating how clearly you see from a distance and which lens prescription, if necessary, will give you the best possible vision, at The Eye Clinic of Texas, we will also perform a number of tests to check the health and function of your entire eye including checking for glaucoma, cataracts, diseases, problems and conditions of the retina such as from diabetes or high blood pressure as well as any other eye health issues related to your overall health.
A trained technician will ask questions about your medical history, your family's medical history, and any vision problems you may have. Please bring your prescription glasses to your exam and if you wear contact lenses, bring them to your exam so we can check the prescription, fit, and make sure they are the best kind of lens for your eyes.
We will take a visual acuity test measurement to determine how well you can see at distance by covering one eye at a time, looking at an eye chart and reading letters that get smaller as you read farther down the chart. If your visual acuity test indicates that you need corrective lenses, you will be given a refraction test to determine the correct prescription and we will finalize the prescription by asking you to look through a device called a Phoroptor that has many different lenses in it in order to compare and determine the combination that provides you with your best possible vision correction.
Then, we will test eye muscle function by following the movement of an object in many directions, looking for weak muscles or poor control of the muscles that move your eyes. In order to test your peripheral vision, we use a visual field test and ask you when you can see the technician’s or finger as it moves inward from outside your visual field. Sometimes we may use a computer program to test your visual field by looking into a special device, often a lighted bowl-shaped instrument, and press a button each time you see a flash of light. We can use your responses to see if there are any blind spots in your visual field.
We will use a slit-lamp microscope to examine the front part of your eye, including the cornea, iris, and lens. You will sit at the slit lamp, which greatly magnifies your eye and shines a bright line of light into it, allowing us to examine your eye closely. We will test for glaucoma using a tonometer to measure your intraocular pressure after instilling a few eye drops containing an anesthetic and fluorescein dye to numb the front surface of your eye and will gently touch your cornea. This procedure is quick and painless. We may also use pachymetry to measure the thickness of your cornea, which helps evaluate the accuracy of your intraocular pressure measurement.
A retinal examination explores the back of your eye including the retina and optic nerve after we instill eye drops to dilate your pupils. Retinal examinations usually take about five minutes, but the eye drops will continue to blur your vision for several hours. You may not be able to drive and will be sensitive to bright light, but this is temporary and should resolve in several hours.
The frequency of your eye examinations really depends on a number of factors including your age, whether your family has a history of eye problems and whether you have been diagnosed with or treated for any eye conditions or diseases in the past. This will determine how often the The Eye Clinic of Texas eye doctors suggest that you schedule your visits as well as what type of examination is necessary.
