Toxoplasma antibodies in ophthalmological patients.

Sera of 532 patients suffering from different ophthalmological diseases were studied for the presence of toxoplasma antibodies. Complement fixation test was positive in 44.9% of the patients. As compared with the 26.8% positivity rate determined earlier in the normal population the seropositivity in eye-patients was significantly higher. The highest incidence, 50%, was found in the age group of 21--30 years. In diseases with a confirmed aetiological role of toxoplasmosis, the incidence of seropositivity was higher than in the total material. This suggests that Toxoplasma gondii may have had a role in part of the diseases of the patients studied.
