Abstract

ABSTRACT

INTRODUCTION: Ocular toxoplasmosis is a disease caused by Toxoplasma gondii through congenital or acquired routes. Once parasite reaches retina, it makes primary lesions. Restricted parasite by host immunity in first scar is activated to infect other cells, leads to another lesion near old scar.

CASE REPORT: A 21 year old female presented with defective vision, floaters in left eye since 2months. On examination anterior segment was quiet and posterior segment showed vitreous cells of grade 2 and active chorioretinitis lesion nearer to old chorioretinal scar in macular region. Investigations showed Toxoplasma gondii IgG antibody positive and other tests were negative.

DISCUSSION: It is the common cause of infective posterior uveitis in immunocompetent individuals. Acquired toxoplasmosis presents as ‘head light in fog’ appearance, consists of focal necrotizing retinochoroiditis with severe vitritis.

CONCLUSION: Prompt diagnosis and treatment improves vision.
