Case report: Pupil sparing third nerve palsy in an immunocompetent host – A rare sequelae of congenital ocular toxoplasmosis

We share a case of a 20 yr old female who presented with drooping of left upper eyelid with down and outward deviation of left eye since birth and diminution of vision in left eye noticed since 2 yrs with retinal abnormalities suggestive of congenital ocular toxoplasmosis. The clinical and complementary examinations of the case are discussed. Ocular toxoplasmosis remains to be the most common cause of infectious posterior uveitis in immunocompetent and immunocompromised individuals with highly variable prognosis. A precise diagnosis of the disease is necessary to opt effective and rapid treatment. Hence, It is essential that clinicians be aware of antenatal and postnatal presenting signs and symptoms, as early diagnosis and treatment will minimise the possibility of sequelae as majority of affected infants may develop chorioretinitis, deafness and/or neurological symptoms if left untreated.
