Progression to Vision-Threatening Retinopathy Complications Following Panretinal Laser for Proliferative Diabetic Retinopathy

To report the time in which patients with panretinal photocoagulation (PDR) progress to vision-threatening retinopathy (VTR) complications after receiving PRP, and risk factors in routine clinical practice.Records of patients with complete PRP for PDR were retrospectively reviewed for up to 3.5 years after PRP. Two hundred twenty eyes were selected.Time from PRP to VTR was 1.25 ± 0.82 years. Age, Black race, neovascularization of the disc on examination, diabetic foot disease (DFD), and high-risk PDR characteristics on fluorescein angiography were identified as significant risk factors. Half of patients with DFD on examination developed a VTR within 1.5 years after PRP (P < .001).In clinical practice, providers may consider DFD and Black race as predictors of time to VTR event within 4 years after PRP in patients with PDR.
