Ch 7. Eales Disease of the Retina


Eales’ disease was initially described in young males with vitreous hemorrhage and abnormal retinal veins.[59] Now it is clinically defined by an obliterative vasculopathy involving both venules and arterioles (Figure 7-9).[60] In the late stages, ischemia leads to neovascularization with resulting vitreous hemorrhage, retinal detachment, and secondary glaucoma.[61][62] Specimens are obtained when vitrectomy is done to remove persistent vitreous hemorrhage or extraretinal fibrous tissue.[63] Cytologic specimens may show vitreous hemorrhage (hemoglobin spherulosis) and, occasionally, fibrous tissue (Figure 7-10).
Other conditions that produce neovascularization and vitreous hemorrhage include branch retinal vein occlusion,[64] sickle cell retinopathy,[65] carotid and aortic arch occlusive syndromes,[66] and hyperviscosity syndromes.[67]
