Diagnosis of Retinal Disorders and Ways To Prevent Them

Our eyes are one of the most essential and delicate parts of our body. After all, we see this world through them. Therefore, it becomes essential to detect and treat eye diseases or retinal disorders at a very early stage as some eye diseases may result in eyesight loss if ignored for a long time.

Tests to Diagnose Retinal Disorders

Tests to Diagnose Retinal Disorders

An ophthalmologist checks your eyes properly and tries to find out the abnormalities there if any to diagnose the issue. These tests are conducted to find out the location as well as the severity of the retinal disease. Below are given some tests that can be performed if you suffer from any retinal disorder:

  • OCT or Optical Coherence Tomography – It is considered a fabulous technique for getting the retina’s precise image to diagnose macular swelling, macular holes, and epiretinal membranes, to monitor treatment’s responses, and to monitor the severity of AMD or Age-related macular degeneration.(3,4)
  • Amsler Grid Test – In this test, an Amsler grid is used in order to check your central vision’s clarity. In order to clearly understand the severity of the retina damage, your doctor may ask you whether the grid lines seem distorted, faded, or broken to know where the abnormality takes place on the grid. In case of finding macular degeneration, your doctor may suggest using this test to monitor your condition on your own at home.(5)
  • Fluorescein Angiography – A dye is used in this test that leads to blood vessels in your retina being noticeable under a particular light. It assists in accurately finding out closed, abnormal or leaking blood vessels, as well as slight transformations at the backside of your eye.(6,7)
  • FAF or Fundus Autofluorescence – This test can be done to identify the severity of retinal diseases, such as macular degeneration. Fundus autofluorescence brings to light lipofuscin (retinal pigment) which spreads with retinal damage.(8)
  • Ultrasound – In order to see the retina as well as other structures in one’s eye, this test (ultrasound) makes use of high-frequency sound waves which is also known as ultrasonography. It may also determine specific tissue attributes that may assist to diagnose and treat tumours of the eye.(9)
  • Indocyanine Green Angiography – While conducting this test, a dye is used by the doctor that lights up if exposed to infrared radiation. The captured images display retinal blood vessels as well as the deeper, difficult to observe blood vessels that can be found in a tissue named the choroid behind your retina.(10, 11)
  • MRI or CT scan – These imaging techniques may be used in some cases, to assist evaluate eye tumours or injuries.(12)
