A person who has healthy one eye, only (the other eye's seeing has been lost because of RD, the remaining eye is lasered for holes and tears / his myopia is very high).
Right now he has to take quinine pills for along time. He does not have to take different medicine. He is afraid of its advers effects.
Is it certain to lose visual levels when taking the pills? Could we do anything to reduce the advers effects?
Thank you very much.
