It seems from the history that your grandmother has poor vision, nerve
problems and using eye drops. I think probably she is having glaucoma
seen in elderly individuals which is characterized by increased intraocular pressure
and treated by eye drops. The treatment of the condition depends on the severity of the condition and its response to the treatment.
Since you have not sent any reports I am not able to advice you accurately. Please do send the reports so that I can advice you seeing the reports.
