Abstract

BackgroundWe report a case of diabetic papillopathy (DP) diagnosed using swept-source optical coherence tomography angiography (SS-OCTA).Case presentationA 52-year-old man was referred for evaluation of a swollen optic disc in both eyes. His best-corrected visual acuity was 20/40 in the right eye and 20/100 in the left eye. Fundus examination demonstrated a swollen optic disc, splinter hemorrhages, and radially oriented, dilated vessels over the optic disc in both eyes. Laboratory tests revealed previously unknown diabetes. SS-OCTA was performed to rule out neovascularization of the disc (NVD). B-scan image displayed blood flow signals in the thickened retinal nerve fiber layer of the optic disc and not above the vitreoretinal interface. We diagnosed the patient with DP.ConclusionsThis case showed that SS-OCTA is useful for distinguishing DP from NVD.

Highlights

We report a case of diabetic papillopathy (DP) diagnosed using swept-source optical coherence tomography angiography (SS-OCT angiography (OCTA)).Case presentation: A 52-year-old man was referred for evaluation of a swollen optic disc in both eyes
This case showed that swept-source optical coherence tomography angiography (SS-OCTA) is useful for distinguishing DP from neovascularization of the disc (NVD)
Diabetic papillopathy (DP) is defined as unilateral or bilateral optic disc swelling with no detectable etiology other than diabetes mellitus (DM) [1]

Summary

Introduction

We report a case of diabetic papillopathy (DP) diagnosed using swept-source optical coherence tomography angiography (SS-OCTA).Case presentation: A 52-year-old man was referred for evaluation of a swollen optic disc in both eyes. Conclusions: This case showed that SS-OCTA is useful for distinguishing DP from NVD. The vascular configuration of NVD is typically randomly oriented and usually shows more profound leakage in the early phase of fluorescein angiography (FA) than DP, but these findings are not much helpful for the differential diagnosis.
