A summary of the patients' demographics and clinical characteristics in the primary and recurrent OT groups and control group. OT: ocular toxoplasmosis; SD: standard deviation; PD: diameter of the papilla; a p value < 0.05 is considered as statistically significant; significant p values are shown in bold.
