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

Physical activity is strongly encouraged for individuals living with Leber Hereditary Optic Neuropathy (LHON), as it supports overall cardiovascular health, mental well-being, and physical confidence without worsening the underlying mitochondrial condition. While Leber Hereditary Optic Neuropathy affects central vision, it does not impair motor function, meaning most forms of exercise are safe and highly beneficial when adapted to individual visual needs.

Is exercise safe for people with Leber Hereditary Optic Neuropathy?

Yes, exercise is safe and recommended for those with Leber Hereditary Optic Neuropathy. Because LHON primarily affects the optic nerve, there is no clinical contraindication for physical activity. In fact, maintaining physical fitness is essential for managing the secondary stressors, such as anxiety or depression, that often accompany the sudden vision loss associated with Leber Hereditary Optic Neuropathy.

What types of exercise are recommended?

Focus on activities that prioritize safety and consistency. Since Leber Hereditary Optic Neuropathy results in central vision loss, you should choose environments where you feel secure. Recommended activities include:

• Walking or hiking: Use familiar, flat paths or trails with a guide or a cane if needed.


• Swimming: An excellent low-impact exercise in a controlled, predictable environment.


• Strength training: Resistance bands or weight machines are often easier to navigate than free weights for those with visual impairments.


• Yoga or Pilates: These help with balance and core strength, which are vital as you adapt to changes in your visual field.

How can I start an exercise program safely?

Always consult your ophthalmologist or a neurologist before beginning a new routine. Start with a "low and slow" approach to build confidence. If you are experiencing a period of active vision decline due to Leber Hereditary Optic Neuropathy, use pacing strategies: listen to your body and prioritize rest on days when fatigue is high. Working with a physical therapist who specializes in visual impairment can help you adapt movements and navigate your environment safely.
