Aim: To determine the prevalence of ocular toxoplasmosis among people living with HIV through a systematic review and meta-analysis. Materials & methods: A literature search was conducted, estimating pooled prevalence and performing quality assessment, outlier, influential and meta-regression analyses. Results: Twenty-nine studies were included in the analysis, revealing that the rate of ocular toxoplasmosis among people living with HIV was 0.37% (95% CI: 0.2-0.6). Substantial heterogeneity was observed among the studies. Despite analyzing continuous variables, including year of publication, proportion of males, mean age and proportion of patients receiving antiretroviral therapy, no statistically significant associations were found. Conclusion: This study provides an overview of the prevalence of ocular toxoplasmosis in people living with HIV, emphasizing the need for further research to uncover factors contributing to its development.

This study looked at how common ocular toxoplasmosis, a type of parasitic infection, is among people living with HIV. We did this by reviewing other studies, combining their results and evaluating the quality of each study. We also looked for any unusual findings and other factors that might affect the prevalence of ocular toxoplasmosis. After analyzing 29 studies, we found that approximately 0.37% of people living with HIV had ocular toxoplasmosis, ranging from 0.2% to 0.6%. There was a significant variation in the results among the studies. Our study provides an overview of the prevalence of ocular toxoplasmosis in people living with HIV, highlighting the need for further research to identify the factors contributing to its development.
