The Decreased Cells Number Associated with Retinal Lesion Size in Ocular Toxoplasmosis.

Introduction: The imbalance of the immune response is an important factor contributing to the incidence of ocular toxoplasmosis (OT). Regulatory T cells (Treg) play a key role in maintaining the balance between Th1 and Th17 immune responses, while interleukin-27 (IL-27) levels are related to the differentiation of Th17 cells. This study analyzes the differences in the number of Treg cells and the level of IL-27 between OT patients and seropositive individuals without ocular lesions and its correlation with retinal lesion size.

Optical Coherence Tomography Angiography Findings in Ocular Toxoplasmosis with Multiple Recurrences.

Ocular toxoplasmosis is the most common cause of posterior uveitis that is caused by infection. Humans can be infected congenitally or postnatally. The typical lesion of ocular toxoplasmosis is focal necrotizing retinitis with overlying vitritis, which lead to hyperpigmented retinochoroidal scar at resolution of lesion.
