摘　　要：Dear Editor,Ocular toxoplasmosis,caused by Toxoplasma gondii infection,is one of the most common causes of posterior uveitis worldwide[1].It typically manifests as white focal retinitis with overlying vitreous inflammation that results in a chorioretinal scar and associated scotoma[2].However,the diagnosis of ocular toxoplasmosis can be challenging when it presents as an isolated papillitis without other typical signs of retinochoroiditis or vitritis[2].Although optic nerve involvement in ocular toxoplasmosis was present in 5.3%of cases,isolated papillitis was extremely rare(3 eyes out of 926 patients)and was only considered a presumed diagnosis in such cases given the presence of old toxoplasmic retinochoroiditis lesions[3].Few reports have described optic nerve involvement preceding toxoplasmic retinochoroiditis,while perineuritis,an uncommon form of orbital inflammatory disease involving the optic nerve sheath,has not been reported at all[4-5].Herein,we describe a case of ocular toxoplasmosis that initially presented with optic perineuritis followed by typical retinochoroidal inflammation.To our knowledge,this is the first case report of ocular toxoplasmosis with perineuritis in an immunocompetent individual.
