Abstract

Purpose: Wide-field swept-source (SS) OCT angiography (OCTA) was compared with ultrawide-field (UWF) fluorescein angiography (FA) for evaluating neovascularization (NV) before and after panretinal photocoagulation (PRP) in eyes with treatment-naive proliferative diabetic retinopathy (PDR). Design: Prospective, observational, consecutive case series. Participants: Patients with treatment-naive PDR. Methods: Patients were imaged using the SS OCTA 12 × 12-mm field of view (PLEX Elite 9000; Carl Zeiss Meditec, Inc, Dublin, CA) at baseline and at 1 week, 1 month, and 3 months after PRP. Select eyes were imaged with 5 SS OCTA 12 × 12-mm scans to create posterior pole montages. Ultrawide-field fundus photography and UWF FA were obtained at baseline and 3 months after PRP. Main Outcome Measures: Neovascularization visualized using wide-field SS OCTA and UWF FA. Results: From January through May 2018, wide-field SS OCTA was performed on 20 eyes with treatment-naive PDR from 15 patients. The en face SS OCTA 12 × 12-mm vitreoretinal interface (VRI) slab images showed NV at baseline in 18 of 20 eyes (90%). Of the remaining 2 eyes, the posterior pole montage captured peripheral NV in one eye, and in the other eye, no evidence of NV was detected with either UWF FA or SS OCTA. After PRP, both SS OCTA and FA demonstrated similar progression or regression of NV, but SS OCTA provided more detailed visualization of the vascular changes. Conclusions: Neovascularization in PDR can be identified at baseline and imaged serially after PRP using wide-field SS OCTA. In patients with a high clinical suspicion for PDR, wide-field SS OCTA likely will be the only imaging method needed for diagnosis and longitudinal evaluation of NV.
