Types of Tests and Examinations Performed by Doctors in an Eye Clinic
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.
