Postnataal verworven oculaire toxoplasmose bij een volwassen vrouw

Ocular toxoplasmosis was diagnosed in a 47-year-old woman who attended the ophthalmology outpatient department with a two-week history of diminishing vision in her left eye. Ocular toxoplasmosis in immune-competent patients generally used to be attributed to reactivation of a congenital infection with the parasite Toxoplasma gondii. Over the past decade it has become clear that this problem can also be the result of an infection acquired later in life. This patient had acquired ocular toxoplasmosis postnatally. The infection was treated with sulfadiazine, pyrimethamine, folic acid and prednisone. She was also given topical timolol eye-drops and prednisolone eye-drops. She recovered but later on there was a limited recurrence of the problem whereby a wait-and-see policy was followed. Postnatally-acquired ocular toxoplasmosis can be diagnosed if there is a primary retinal lesion without associated old scars, in combination with specific laboratory results from serum and intraocular fluid.
