PURPOSE: To describe optical coherence tomography angiography (OCTA) findings in eyes with active and scarred toxoplasmic retinochoroiditis.
METHODS: OCTA scans in active (25 eyes) and scarred (17 eyes) retinochoroiditis were retrospectively reviewed.
RESULTS: In active lesions, OCTA findings included a non-detectable flow signal area in retinal vascular plexuses and choriocapillaris in all 25 eyes (100%), an abnormal intraretinal vascular process in 2 eyes (8%), and an associated area of retinal flow deficit secondary to branch retinal artery occlusion in one eye (4%). In scarred lesions, OCTA findings included a flow deficit area in retinal vascular plexuses and choriocapillaris in all 17 eyes (100%), a visibility of larger deeper choroidal vessels at the level of choriocapillaris in 9 eyes (53%), and a well-defined intraretinal vascular network in one eye (5.9%). Peripapillary scars were associated on OCTA with wedge-shaped loss of radial peripapillary capillaries with corresponding localized retinal nerve fiber layer defect and visual field loss.
CONCLUSION: OCTA allows to non-invasively detect retinal and choroidal vascular changes in active and scarred toxoplasmic retinochoroiditis.
