Neuroretinitis, a great mimicker

Abstract

Neuroretinitis is a less-known clinical entity, which can be funduscopically confused with papillitis or papilledema and with hypertensive, renal and infiltrative retinopathies as well as with retinal vein occlusion or anterior ischemic optic neuropathy. Report: Two young patients presented with sudden onset of blurring of vision. Ophthalmic evaluation revealed a characteristic picture of neuroretinitis. Detailed study of the cases failed to indicate any specific etiology, thereby suggesting the diagnosis of idiopathic neuroretinitis. Although funduscopy showed marked inflammatory changes in the retina and optic nerve head, the recovery following medical treatment was remarkable. Comment: Familiarity with the fundus picture and awareness of the specific causes of neuroretinitis among neurologists and physicians may enable a prompt clinical diagnosis, avoidance of expensive brain imaging studies and early referral for appropriate and effective therapy. A brief review of the literature is presented suggesting a need for further studies to establish specific environmentally determined etiological factors such as infections and the effectiveness of the current modalities of treatment.
