Is it advisable to do exercise when affected by Choroideremia? Which activities would you suggest and how intense should they be?

Exercise is generally safe and highly recommended for individuals with Choroideremia to support overall physical health, mental well-being, and functional independence. While Choroideremia is a progressive retinal dystrophy that affects vision, it does not directly impair musculoskeletal function, meaning most physical activities are beneficial when performed with appropriate safety precautions regarding vision loss.

Is physical activity safe for those with Choroideremia?

Yes, staying active is vital for managing the psychological impact of living with a progressive condition like Choroideremia. Physical activity improves cardiovascular health, boosts mood, and helps maintain balance and coordination, which are crucial as peripheral vision diminishes. Our community of 96 people with Choroideremia on DiseaseMaps.org frequently highlights that regular movement helps them manage the stress associated with vision loss.

Which exercises are most suitable for Choroideremia patients?

Focus on activities that provide consistent stability and minimize the risk of injury due to low-light environments or depth perception challenges. Effective options include:

• Walking: Use well-lit, familiar paths or a treadmill with safety rails.


• Swimming: An excellent low-impact activity in controlled, familiar pool environments.


• Stationary Cycling: Provides a safe way to build cardiovascular endurance without navigation risks.


• Yoga or Pilates: Enhances core strength and proprioception, which aids in balance as night blindness progresses.

How can I adapt my exercise routine for safety?

As Choroideremia progresses, night blindness and loss of peripheral vision become more pronounced. To exercise safely, avoid contact sports or activities with unpredictable, high-speed projectiles. Always prioritize environments with high contrast and consistent lighting. If you are having a "bad day" where vision fatigue is high, practice pacing: reduce the duration of your workout rather than stopping entirely, and focus on gentle stretching or guided movement.

Next steps

• Consult with your ophthalmologist to discuss how your current stage of Choroideremia might impact your balance.


• Work with a physical therapist to develop a personalized routine that emphasizes fall prevention.
