In this case, vision can deteriorate very quickly. As doctors note, people suffering from type 2 diabetes have a high susceptibility to this disease.
Glaucoma

When the amount of this substance in the eye increases, it can block the eye's natural drainage system and lead to glaucoma. An increase in pressure, due to which the fluid does not drain from the eye as usual, can damage nerves and blood vessels. It causes vision changes up to blindness. According to the American Diabetes Association, people with diabetes are more likely to develop glaucoma.
