How do I know if I have Usher Syndrome?

Usher Syndrome is a genetic condition characterized by the combination of hearing loss and progressive vision loss due to retinitis pigmentosa. To determine if you have Usher Syndrome, you should look for patterns of congenital or early-childhood hearing impairment paired with the onset of night blindness or narrowing of the visual field, and seek a referral to a geneticist or ophthalmologist for clinical evaluation.

What are the early signs and symptoms of Usher Syndrome?

Usher Syndrome is primarily identified by two main clinical features: sensorineural hearing loss and progressive vision loss. Because the condition is genetic, hearing loss is often present from birth or early childhood. As the individual matures, the vision loss—caused by retinitis pigmentosa—typically begins with difficulty seeing in low light (night blindness) and a gradual narrowing of the peripheral vision, often referred to as "tunnel vision." Some individuals may also experience balance issues due to vestibular (inner ear) dysfunction, which can lead to delays in motor milestones like sitting or walking in young children. With 214 members in the DiseaseMaps.org community living with this condition, we know that the experience of Usher Syndrome varies significantly depending on the specific genetic subtype.

How can I recognize the patterns of Usher Syndrome in myself?

If you suspect you may have Usher Syndrome, it is helpful to document your medical history. Look for these specific patterns:

• Hearing History: Did you have hearing loss identified in childhood? Do you use hearing aids or a cochlear implant?


• Vision Changes: Do you struggle significantly in dimly lit environments? Have you noticed your side vision shrinking over time?


• Balance: Do you experience chronic dizziness or have a history of balance challenges?


• Family History: Are there other family members who have experienced both hearing and vision loss?

When should I see a doctor and what tests should I request?

If you notice a combination of hearing and vision changes, you should consult an otolaryngologist (ENT) and a retinal specialist. When speaking with your physician, be clear about the dual nature of your symptoms. To investigate Usher Syndrome, specifically request the following diagnostic tests:

1. Audiogram: To assess the degree and type of hearing loss.


2. Electroretinogram (ERG): This test measures the electrical response of the light-sensitive cells in your eyes and is the gold standard for detecting retinitis pigmentosa.


3. Genetic Testing: A molecular genetic test is the only way to confirm a diagnosis of Usher Syndrome and identify the specific gene mutation involved.


4. Vestibular Testing: To evaluate balance function if you are experiencing frequent falls or dizziness.

What are the red flags that require urgent evaluation?

While Usher Syndrome is typically a slowly progressive condition, sudden changes in vision—such as a dramatic increase in "floaters," flashes of light, or a sudden "curtain" falling over your vision—require immediate evaluation by an ophthalmologist to rule out retinal detachment. If you feel your concerns are being dismissed, do not hesitate to seek a second opinion from a specialist at a university hospital or a center for rare eye or ear disorders. Bring documentation of your symptoms and ask for a referral to a genetic counselor, who can help coordinate testing for Usher Syndrome.
