Group report on diabetic retinopathy - insight will be helpful

Hi guys, I’m doing a group report on a patient with Parkinson’s disease of co mobility of diabetic retinopathy previously treated with PRP laser so if anyone has any insight of specifically medication how you take medication? Are you able to read small labels? How you come about this? Do you have any AIDS management or techniques to help you whether they optical aids such as a magnifiers or non-optical aid such as larger print or steady eye strategies, thank you
