Please let me know if there is any thing to cure the loss of vision from macular damage?

Depends. On what process is occurring to cause the damage. Ask your ophthalmologist.
Hasrd to say. There are so many ways vision can be lost from macular "damage." if the macula is damages from trauma or there is severe scarring, teh prognosis is generally very poor. Some conditions can be treated with some vision improvement. Best to see a retina specialist, they are very knowledgeable on these types of problems.
