Diabetic papillopathy (DP) is characterized by unilateral or bilateral optic disc swelling with no detectable etiology other than diabetes mellitus (DM). It is a self-limiting condition that usually resolves over a period of 2–10 months without significant visual sequelae. There is no validated treatment for DP. Serial examination is the most common management because of the benign nature of this condition.

A 52-year-old man was referred with a 1-week history of acute painless decreased vision in both eyes (OU). His best-corrected visual acuity (BCVA) was 20/40 in the right eye (OD) and 20/100 in the left eye (OS). Fundus examination showed swollen optic discs with superficial radially oriented telangiectatic vessels, peripapillary splinter hemorrhages, and hard exudates OU. On SS-OCTA, B-scan images displayed blood flow signals in the thickened retinal nerve fiber layer (RNFL) of the optic disc and superficial RNFL slab images displayed radially oriented telangiectatic vessels OU. Laboratory tests revealed previously unknown diabetes, and we diagnosed the patient with DP OU. Two weeks after an intravitreal injection of bevacizumab OS, the disc swelling, radially oriented telangiectatic vessels, and peripapillary splinter hemorrhages had decreased OS. The superficial RNFL slab OS also depicted decreased radially oriented telangiectatic vessels. However, OD showed no interval changes. Two weeks after an intravitreal bevacizumab injection OD, improved BCVA, decreased disc swelling, radially oriented telangiectatic vessels, and peripapillary splinter hemorrhages were observed OU. The superficial RNFL slab also showed decreased radially oriented telangiectatic vessels OU.

This case showed that bevacizumab is a useful treatment option for DP as they resolve underlying optic nerve capillary vasculopathy. SS-OCTA demonstrated resolved superficial telangiectatic vessels of the optic disc which has not been previously described.
