An objective analysis of proliferative diabetic retinopathy before and after pars plana vitrectomy.
Nineteen eyes on which pars plana vitrectomy was performed were studied with fluorescein angiography. The degree of background diabetic retinopathy before and after surgical treatment appeared unchanged. The degree of proliferative retinopathy not only was less after surgical treatment, but continued to show regression with time.
