My mother is diabetic her vision is grtting blurred doctor says she's having bleeding behind her cornea.can any treatment save her eye sight?

Laser eye surgery: Bleeding in the eye could be retinal hemorrhages or vitreous hemorrhage which itself does not cause permanent vision loss. For your grandma to have blurry vision it is caused by macular edema or ischemia. Laser eye surgery may help. Talk to an ophthalmologist. Optimal blood glucose control is key to prevent further damage

Eye doctor: An ophthalmologist or eye doctor can help her. Please arrange for an appointment with your doctor to be referred to this specialist.
