We were able to find two reports in the literature of monozygotic twins suffering from toxoplasmosis and lesions of the eyes. One of Zuelzer's patients died at the age of one month. Post-mortem examination revealed iritis, chorioretinitis in the macula and the intraocular presence of parasites.

In Abbott and Camp'scases, both twins exhibited bilateral widespread chorioretinitis associated with retinal angiomatosis.
