Abstract
Purpose: In acute retinal necrosis, which is caused by herpes virus, urgent treatment is essential. Design and Methods: Here we present a 47years old male patient, who developed an acute retinal necrosis in his left eye. Therapy was initiated with systemic aciclovir and corticosteroids. Results: During the course of disease our patient achieved improvement of acute retinal necrosis but he developed central serous chorioretinopathy. Conclusions: The development of central serous chorioretinopathy in our patient was most probably due to the systemic corticosteroids he received. Especially in patients with an intraocular inflammation this diagnosis may lead to severe differential diagnostic problems.
