Answer: There are several means to losing vision with diabetes. The most common is from macular edema - leaking vessels near the fovea/macula (the part of the retina responsible for central vision) can cause localized swelling that can affect best corrected vision. This is very common, and ophthalmologists watch for this and can treat the area with focal laser therapy if the swelling falls within treatment criteria.
The next most common cause for vision loss is vitreous hemorrhage (from leaking neovascular vessels).
Other possibilities include tractional retinal detachment from fibrosing/contracting areas of neovascularization. Also, acute glaucoma (from neovascularization of the iris/angle).
Finally, diabetics have higher rates of cataract formation (often PSC cataracts on the back of the lens).
