Familial exudative vitreoretinopathy - The exudative vitreoretinopathies (EVR) are a group of genetically heterogenous familial disorders believed to be caused by arrested peripheral retinal angiogenesis/vasculogenesis or retinal vascular differentiation. Clinical features vary, even within families, from blindness in childhood to patients with few or no visual problems who may be diagnosed only following fluorescein angiography.read more
