Jelly-like substance that fills the space within the eyeball. No, some diabetics may get glaucoma or cataracts. Glaucoma is a build-up of pressure in the eyeball.
Cataract is when excessive blood-glucose levels change proteins in the lens.
The altered proteins cause the lens to lose its elasticity, and patients are unable to focus clearly. These eye troubles sound terrible. An opthamologist can check for retinopathy during a routine eye examination. If the patient follows those two rules, there should be no hidden ocular complications.
