Title

Effects of panretinal photocoagulation on retinal vasculature and foveal avascular zone in diabetic retinopathy using optical coherence tomography angiography: A pilot study

Pages

  287-291

Abstract

 Purpose: To evaluate the Optical coherence tomography angiography (OCTA) parameters in patients with Diabetic retinopathy following Panretinal photocoagulation (PRP). Methods: Eleven eyes of 6 patients with very severe nonproliferative Diabetic retinopathy (NPDR) or early proliferative Diabetic retinopathy (PDR) were recruited in this prospective interventional pilot study. All patients underwent OCTA imaging at baseline, and choroidal flow, Foveal avascular zone (FAZ), retinal thickness, and vascular density were measured at baseline. Three months after treatment, OCTAwas repeated, and the alteration in variables was analyzed. Results: The FAZ area remained unchanged following treatment, (P ¼ 0. 75). Retinal thickness increased along (P ¼ 0. 02) with an increase in vascular density in the superficial and deep foveal area and the macular temporal sector (P ¼ 0. 007, 0. 03 and 0. 049, respectively). Choroidal flow surface area was unchanged (P ¼ 0. 10). Conclusion: In this study, foveal vascular density increased and FAZ remained unchanged after PRP for Diabetic retinopathy.
