Ocular toxoplasmosis is the most common cause of retinochoroiditis worldwide in humans. Some studies highlighted the idea that ocular lesions differ according to the route of infection but none of them mimicked the natural route. The current study aimed to investigate the ophthalmic outcomes in congenital and oral routes of infection with Toxoplasma in experimental animals. Mice were divided into three groups; group I: congenital infection, group II: acquired oral infection and group III: non-infected. We used Me49 chronic low-virulence T. gondii strain. We found that retina is the most affected part in both modes of infections. However, the retinal changes are different and more pronounced in case of congenital infection. The congenitally infected mice showed retinal lesions e.g. total detachment of retinal pigment epithelium from the photoreceptor layer and irregular arrangement of retinal layers. More severe damage was observed in mice infected early in pregnancy. While the postnatal orally infected mice showed fewer changes. In conclusion, the routes of Toxoplasma infection affect the ophthalmic outcomes and this may be the case in human disease. Although both are vision threatening, it seems that the prognosis of postnatal acquired ocular toxoplasmosis is better than that of congenital disease.
