What are the long-term consequences of congenital ocular toxoplasmosis?
The chorioretinal scars of congenital ocular toxoplasmosis are generally inert. However, the encysted Toxoplasma organisms can reactivate causing inflammation, pain, redness, sensitivity to light, blurred vision, and increased intraocular pressure. Examination during reactivation reveals a cloud of white blood cells overlying the whitened patch of inflamed retina. In severe cases, the view into the eye is quite cloudy, and the underlying acute inflammation can be only dimly perceived.
