Thirty-five patients with toxoplasma retinochoroiditis, receiving medical treatment and then treated with laser photocoagulation around the foci, were retrospectively evaluated for the risk of recurrence of the retinochoroiditis with a Kaplan-Meier representation. The recurrence rates with 95% symmetric confidence intervals were: at 1 year, 12.7 ± 13%; at 2 years, 19.8+15%; at 3 years, 24.0 ± 16%; at 4 years, 33.3 ± 19%; at 5, 6 and 7 years, 53.5 + 21%; at 8 and 9 years, 66.8 ± 22%. With the data provided by our series, it is not possible to show the efficacy of laser photocoagulation as a prevention of recurrence in toxoplasma retinochoroiditis. Moreover, because of their heterogeneity, the recurrence rates from the literature cannot provide precise data for a comparison.
