| Summary: | Purpose: We report a case of diabetic papillopathy (DP) treated with intravitreal bevacizumab injections and evaluated for disc vessel changes using swept-source optical coherence tomography angiography (SS-OCTA). Observations: 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. Conclusions and importance: 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.
