Hello @barbarn, I think you have done an excellent job of identifying the options available for your husband along with an important question that needs to be answered. I agree with Rosemary @rosemarya that all medicines come with some level of risk and it boils down to a risk vs. benefit decision at some point. I would also recommend talking with his opthamologist and the doctor about the pros and cons of his treatment.

I would also think your husbands thoughts would be important on the choices.
