idiopathic posterior uveitis
Idiopathic posterior uveitis is a rare, potentially sight-threatening, ocular disease, not attributed to any specific ocular or systemic cause, characterized by focal, multifocal or diffuse non-infectious inflammation in the posterior uvea (i.e. choroiditis, chorioretinitis, retinitis and neuroretinitis). Visual morbidity due to complications (including cystoid macular edema and choroidal neovascularization) has been reported.
