Ocular findings in Congenital Toxoplasomsis:
- 79% patients have chorioretinal scars *Scar may involve macula with significant decrease in visual acuity
- scar may involve periheral area with decreased acuity by dragging of macula

Other posterior ocular complications include:
- retinal attachment and active chorioretinitis in 10%
- Optic atrophy in 20%
