Our eye genetics specialists can offer a variety of tests depending on your individual needs. These tests might include some or all of the following:

  • Dilated eye exam – This exam includes measurements of near and distance visual acuity, manifest refraction, color vision, and ocular pressure. The eye doctor will also examine the entire eye with a focus on the retina and macula.
  • Visual field testing – This test allows the eye doctor to see whether a person has any areas of vision loss. This can be useful for conditions such as retinal dystrophy or degeneration, which can cause loss of peripheral (side-to-side) vision, and macular dystrophy, which can cause blind spots in central vision.
  • Electrophysiology – Electrophysiological tests show the eye doctor how electrical signals are transmitted inside the eye. They include:
    • Electroretinogram (ERG) – This test measures how the retina responds to light, and is used for people who have symptoms of a retinal disease. There are two main types of ERG: the full-field and the multifocal ERG. Each test measures the retina’s response in a different way.
    • Electro-oculogram (EOG) – This test is similar to the ERG, only it is used for people with symptoms of a macular dystrophy. The EOG takes one hour to perform.
  • Family history – For this exam, a genetic counselor will ask the patient questions to help determine whether he or she has an inherited eye disease, and how it might have been inherited. The counselor will then work with one of our doctors to provide the patient with options for molecular tests that can confirm the diagnosis and inheritance.
  • Additional testing – This can include blood tests, photography of the eye, and color vision testing.
