Swept-source optical coherence tomography angiography of diabetic papillopathy: a case report

We report a case of diabetic papillopathy (DP) diagnosed using swept-source optical coherence tomography angiography (SS-OCTA). A 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. This case showed that SS-OCTA is useful for distinguishing DP from NVD.
