Regular eye exams are important because they can pick up early signs of eye conditions such as glaucoma and cataracts. Adults and children are usually advised to schedule an eye exam at an eye clinic every one to two years. In addition to a complete examination of the eye, an eye doctor may want to arrange one or more of the following eye tests. Applanation Tonometry This eye test involves placing a dye in the eye and measuring the pressure in the eye with an instrument called a tonometer. It helps an eye doctor diagnose glaucoma. Corneal and Retinal Topography These computerized tests are used to analyze the surface of the retina or curvature of the cornea for distortions such as scarring or swelling. The corneal test may be used to evaluate the eye prior to eye surgery or the fitting of contact lenses.
You may think your eyes are in good health, but visiting an optometry clinic for a dilated eye examination may tell you otherwise. These eye exams are among the many procedures that can ascertain that your eyes are in perfect shape. During the exam, your dilated eyes will be closely examined for signs of common eye diseases and conditions, many of which develop slowly over time. What Happens During A Dilated Eye Exam? Your optometrist will put drops into your eyes, causing your pupils to widen. It takes approximately 20 minutes for the drops to take effect. Once your pupils have widened, your optometrist will be able to examine the retina, the light-sensitive tissue lining the back of your eye, and optic nerve, the nerve that connects the retina to your brain, for signs of eye diseases and conditions, such as age-related macular degeneration, retinal detachment and eye tumors.
