My mother has glaucoma, and she has now lost around 70% of her vision in one eye. Several eye doctors have told us that the vision loss cannot be reversed. I would like to know how we can best take care of her condition and protect the vision she still has. Are there any treatments, procedures, lifestyle changes, or other options that could help prevent further vision loss? I would really appreciate advice from ophthalmologists or anyone with experience dealing with advanced glaucoma. Thank you.
