[Retinal tears in toxoplasmic retinochoroiditis: case series].
This study is a retrospective case series aiming to evaluate the relation between toxoplasmic retinochoroiditis scars and the occurrence of retinal tears. Ten patients with retinal tear and toxoplasmic retinochoroiditis examined at the School of Medicine of Ribeirão Preto Clinics Hospital, between January 2007 and April 2008, were included. Fisher test and qui-square test with significance level of p<0.05 were used. Eight cases (80%) had retinal detachment. Twelve tears were found and localized mostly in the temporal superior periphery (6 cases, 50%). No statistically significant association between retinal tear and chorioretinal scar localization was observed considering five retinal quadrants (p=0.0828) or three zones (p=0.2507). The occurrence of retinal tears in patients with uveitis may be related to early posterior vitreous detachment caused by the intraocular inflammatory process. No correlation was observed between the localization of retinal tears and chorioretinal scars in this study, which suggests a causative factor not directly related to the presence of a scar.
