If diabetic retinopathy is detected early, laser surgery slows down vision loss. If the vitreous is clouded by blood, laser surgery cannot be used until the blood settles or clears. In some cases of bleeding into the vitreous, cryotherapy, or freezing, of the retina may help shrink the abnormal blood vessels. In advanced proliferative diabetic retinopathy, the ophthalmologist may recommend a vitrectomy. This microsurgical procedure is performed in the operating room.
Vitrectomy removes the blood-flled vitreous and replaces it with a clear solution.
Sometimes the ophthalmologist may wait from several months up to a year to see if the blood clears on its own, before going ahead with a vitrectomy. Successful care of diabetic retinopathy depends on more than early treatment by your ophthalmologist. Your attitude and attention to medications and diet are essential . You must maintain blood sugar levels, avoid smoking and watch your blood pressure. Physical activity is usually no problem for people with background retinopathy.
