What is genetic testing?
- There are many ways to conduct a genetic test; with the AvaGen test from Avellino, a simple swab of the inside of your cheek is all it takes
- The swab collects a sample of cells that is then transferred to a vial containing a preservative solution. This sample is then sent to our lab where Avellino sequences the genes and identifies mutations that may indicate a disease or a risk for a disease
If your eyecare professional is able to diagnose, treat, or manage your disease earlier, it may make a big difference to your overall eye health and vision.
Talk to your physician or eyecare professional about testing.
Why should I get my eyes tested?
Genetic testing is an important step in diagnosing diseases, such as keratoconus or corneal dystrophies. When your doctor suspects that you may have a genetic disease or could develop one in the future, it’s important to get tested so you can confirm a diagnosis or risk factors and take appropriate steps.
These steps might include treatment or preventive measures, such as not rubbing your eyes or avoiding certain types of eye surgery, which could make your condition worse.
Remember, the earlier you identify a disease, the more opportunities you may have to treat the disease or slow the progression.

The AvaGen™ Genetic Eye Test
AvaGen™ delivers precise, genetic data for personalized eyecare decisions.
- Personalized: AvaGen™ uses DNA to accurately assess your individual genetic risk or likelihood of keratoconus, and determine if you have a corneal dystrophy.
- Preemptive: As a genetic test, AvaGen™ relies on your DNA and not physical changes in your eye, allowing for earlier detection and proactive management.
- Painless: A DNA sample is simply taken from the inside of your cheek with a cotton swab.
AvaGen™ helps your doctor understand:
- If you’re at risk for keratoconus.
- If you have a corneal dystrophy.
- Whether or not you can undergo corneal procedures, including vision-correction procedures like LASIK.
Quick, Easy, Non-Invasive Testing
The AvaGen™ genetic eye test provides information to help your doctor best protect and preserve your vision. The test only requires a few simple steps, and is performed quickly in the doctor’s office.
If your doctor recommends and orders the AvaGen™ genetic eye test for you, it will most likely happen on the same day of your office visit.
Your doctor will swab the inside of both your cheeks to collect DNA.
The office sends your sample to the lab.
Your doctor will inform you of the results, answer any questions you may have, and discuss potential next steps with you.
Comprehensive genetic counseling sessions are available for patients who have undergone testing with the AvaGen™ genetic eye test.
Genetic counselors are available to help you understand your genetic eye test results and implications for your family members.
How do I get tested?
Ask your doctor to order the AvaGen genetic test. After your doctor sends your sample to the lab, you may get results back as quickly as 5 days.
If your test confirms a risk for developing keratoconus or the presence of corneal dystrophy, you and your doctor may consider creating a management or treatment plan. You might also want to speak with a genetic counselor.
Avellino provides a network of genetic counselors if your test results reveal a risk or positive results. These counselors work with you and your doctor to provide further details that could help you moving forward.
