We have seen people with macular degeneration, retinitis pigmentosa and Stargardt disease benefit from a regular practice of mindful breathing, breathing slower and more fully than you usually do.

Finally, there is a treatment called Exercise With Oxygen Therapy (EWOT), if you have access to the equipment.
