a Color fundus at the time of diagnosis. An active toxoplasmic lesion is visible adjacent to the retinal choroidal pigmented scars. b An optical coherence tomography (OCT) B-scan with slabs extending from the vitreous to the inner nuclear layer. Thickened choroidal tissue is seen adjacent to the lesion site (asterisk). c An OCT B-scan with overlying color-coded flow in which red represents the retinal capillaries and pre-retinal neovascularization, and pink represents the choroid. d A 6 × 6-mm field of view on OCT angiography (OCTA) shows a neovascular seafan-like complex (arrow) and areas of no decorrelation signal. e A structural en face OCT shows a hyporeflective lesion suggestive of retinal neovascularization. f A color fundus image obtained 5 weeks after those in (a–e) shows that the area of retinitis has regressed following ocular toxoplasmosis treatment. g An OCT B-scan with slabs extending from the vitreous to the inner nuclear layer. h An OCT B-scan with overlying color-coded flow shows that the retinal neovascularization appears unchanged after the systemic anti-Toxoplasma treatment. i A 6 × 6-mm OCTA image shows unchanged retinal neovascularization (arrow). j A structural en face OCT image
