Background We report a case of white circular spots of iridian atrophy, which we will call "polka dots" pattern, as a rare ophthalmological finding associated with uveitis secondary to varicella-zoster virus and Toxoplasma gondii coinfection in a male patient in Bogotá, Colombia. Case presentation We present de case of a 53-year-old Colombian male patient with a diagnosis of anterior uveitis in his left eye due to varicella-zoster virus and Toxoplasma gondii coinfection documented by polymerase

He presented with multiple areas of superficial white circular spots of iridian atrophy in 360º, some with deeper atrophy where the stroma fibers were visualized and only a small punctate defect of transillumination was evident. This rare pattern of iridian atrophy has not been previously described in cases of uveitis in the literature. Conclusions This is the first case reporting the findings of superficial "polka dots" pattern iridian atrophy in 360° secondary to anterior uveitis due to the coinfection of a virus and a parasite. The identification of similar clinical cases may lead to early initiation of systemic treatment in these patients.
