Extract

To the Editor In their Viewpoint, Gross and Glassman1 have concluded that intravitreal anti–vascular endothelial growth factor (anti-VEGF) is noninferior to panretinal photocoagulation (PRP) in the treatment of proliferative diabetic retinopathy (PDR). We have a few concerns about this approach of using anti-VEGF for PDR.

In the study by the Diabetic Retinopathy Clinical Research Network2 on which this Viewpoint is based, worsening of fibrosis was included as a failure criterion in the anti-VEGF group and PRP could be performed in such eyes at investigator discretion. The investigators reported that at least 12 eyes (6%) required secondary PRP in the anti-VEGF group, for which 8 PRP treatments were done during vitrectomy. However, the baseline characteristics, causes for vitrectomy, and final outcome of these eyes have not been separately analyzed.
