[Anterior ischemic optic neuropathy secondary to retrobulbar hematoma].

Two clinical cases are displayed, age over 70, with multiple vascular risk factors; following the retrobulbar injection performed for cataract surgery, retrobulbar hematoma and ischemic anterior neuropathy developed as complications. Pathogenesis of the optic ischemic anterior neuropathy may be explained by changes of a precarious hemodynamic balance and witch was previously settled, due to mechanic compression and increase of the intraocular pressure, which lead to the decrease of the blood pressure and implicitly to the development of optic neuropathy.
