When it comes to maintaining healthy eyesight and the treatment of eye problems, carrying out tests is the only way to identify the problem, make the diagnosis, and administer the right treatment. These tests also help to monitor and keep tabs on your eye health. They differ according to the symptoms being experienced by the patient. Some of these tests are listed below.

Slit-Lamp Exam

When carrying out this test, the eye doctor will look through a microscope called a slit-lamp. This lamp has intense light which is used to get a better view of your eye and allows the optometrist to examine parts of your eyes such as your cornea, lens, anterior chamber and, iris. In some cases, your optometrist would use a special eyedrop so that he/she can easily identify injuries, tiny objects, or infections that might be on the cornea and changes in the lens that could lead to cataracts.

Visual Acuity Test

It is popularly known as the eye chart test. During the test, the eye doctor tells you to read different lines of letters from an eye chart in front of you. They might ask you to read each line twice, using one eye at a time. Your ability to read the letters on the chart will determine the vision level present in each eye.

Visual Field Examination

When the doctor carries out a visual field test, the purpose is to check your direct and peripheral vision. It is used to check how well the nerves at the back of your eye that help detect objects in the field of view are working. For this test to be done, a device called an auto perimeter is used. This device is a bowl-shaped machine that releases small flashes of light. Your optometrist will tell you to stare at one spot in the middle and then press a button whenever you see a light flash in your eyes.

Auto Refraction Examination

The purpose of an auto-refraction examination/test is to measure the changes in the light as it gets into the patient’s eye to calculate your glasses prescription accurately. It is the starting point test when you visit your optometrist. Sometimes, when children are being tested, your optician might carry out the refraction by directing light into the patient’s eyes from a distance. This is known as retinoscopy.

Intra-Ocular Pressure Test

This is a test aimed at measuring the pressure that is inside your eyes. A device called a tonometer will be used to check if the patient is at risk of developing glaucoma. Before the test, numbing eye drops will be administered to your eye. Then the doctor will touch a small strip of paper that contains orange coloured dye to the surface of your eye which will create a stain on it. This makes the test more accurate. You would then be told to look into a slit-lamp while the tip of the tonometer touches your cornea. Your eye doctor will make the necessary adjustments to get the right reading. The numbness of your eyes will make you not feel any pain throughout the procedure.

Optical Coherence Tomography

This test makes use of light waves to do a scan of your retina. It enables your eye care provider to see all layers of the retina and measure them for accurate diagnosis and treatment of retinal diseases such as glaucoma, diabetic, and hypertensive retinopathy and even brain tumours.
