Toxoplasmosis - Retinochoroiditis

Above are images of a 29-year-old male who was seen for complaints of a blurred spot in his right eye. His best corrected vision was 20/70 in the right and 20/20 in the left. Confrontation visual field revealed an inferior temporal constriction in his right eye while his left eye was normal. He was diagnosed with toxoplasmosis retinochoroiditis when his toxoplasma IgG and IgM serologies both returned high. Absence of an adjacent chorioretinal scar and a positive IgM indicates primary acquired toxoplasmosis. Fluorescein angiography shows leakage in the superior-nasal quadrant (yellow arrows). His fundus autofluorescence image shows hyper-reflectivity of accumulated subretinal fluid (light blue arrow). The OCT shows the subretinal fluid (red arrow). He was placed on Bactrim-DS for 6 weeks and later Prednisone 60mg. At his latest exam, his vision in the right eye improved to 20/50 and the follow-up OCT showed resolution of subretinal fluid (white arrows).
