Abstract

Thirty four patients with retinochoroiditis initially treated with medical treatment and later treated with laser photocoagulation around the foci were retrospectively evaluated for the risk of recurrence of the eretinochoroiditis. We used a Kaplan-Meier representation to show the evolution of the number of patients without recurrence as a function of time and as the number of patients followed up decreases (rate of patients without recurrence at 1 year: 86 +/- 12.3% for 26 patients exposed; at 2 years: 75 +/- 16.4% for 20 patients exposed; at 3 years and at 4 years 70 +/- 17% for 17 patients exposed). The recurrence rates were compared to the data previously published in the literature. We failed to demonstrate the efficacy of laser photocoagulation on inactive retinochoroiditis for prevention of recurrence of ocular toxoplasmosis. However, the heterogeneity of our series, the great amount of patients lost to follow up, and the heterogeneity of the recurrence rates of the literature contribute to explain that result.
