Congenital ocular toxoplasmosis. Possible occurrence in siblings.

In two siblings, we saw bilateral macular lesions that were consistent with the diagnosis of congenital toxoplasmosis. Although the congenital nature of this type of infection cannot be proven conclusively, there is considerable evidence that the lesions in our young patients were scars from congenital toxoplasmic retinochoroiditis. To our knowledge, congenital ocular toxoplasmosis in siblings has not previously been reported.
