Treatment Response in Sympathetic Ophthalmia as Assessed by Widefield OCT Angiography

The authors report the widefield montage swept-source optical coherence tomography angiography (OCTA) findings in a 36-year-old male with sympathetic ophthalmia and illustrate the presence of multiple small areas of choriocapillaris flow voids that likely correspond to areas of choriocapillaris ischemia. Using sequential imaging, the authors observed that these flow voids improved following initiating of steroid and immunosuppressive therapy and almost completely resolved following 6 months of therapy with corresponding improvement in visual acuity. This report highlights the role of widefield montage OCTA to detect these likely ischemic changes within the choriocapillaris in sympathetic ophthalmia and demonstrates that they can be used as an anatomic marker to monitor treatment response.
