Types of Eye Tests Done in an Eye Examination


Tests range from simple ones, such as reading an eye chart, to more detailed and complicated ones that use high-powered lenses to check the inside of your eye. A comprehensive eye examination involves both basic and complex procedures to determine the best way to treat your eyes.

Since eyesight is so essential, you must always be proactive in taking care of your eyes. The care process involves a visit to the doctor and carrying out several tests. This article highlights various tests you should expect during your visit to facilities like Maple Grove Vision Clinic.

Refraction Test

This is the test that doctors use to come up with prescription glasses. It usually involves reading of a text in a chart that has been placed 20 feet away, or in a glass pane/mirror that makes things look like they are 20 feet away. The blurriness or clarity that you report determines the type of contact lenses or glasses ideal for you. This test also helps the doctor identify cases of hyperopia, presbyopia, myopia, and astigmatism.

Fluorescein Angiogram

This test enables the doctor to see how the blood flows in the retina. It is used for the diagnosis of retinal detachment, macular degeneration, and diabetic retinopathy. The fluorescent dye used helps in the identification of the problematic areas by highlighting leakage, swelling, abnormal blood vessels, and blood circulation problems inside the eye.

Corneal Topography

This computer oriented test works by mapping the curve of your cornea. It highlights various problems in your eyes such as scarring, swelling, and eye conditions such as astigmatism. It is performed typically before a cornea transplant, surgery, or contact lens fitting.

Eye tests are simple and painless procedures which seek to improve and safeguard your eyesight. After the tests, your doctor will recommend treatment plans for your condition. In case of a surgery, ensure that you get a comprehensive aftercare program from the doctor to help you recover faster.
