Sudden loss of sight.
Clinic. The sudden loss of sight can arise at acute impassability of the central artery of a retina (an angio-spasm, an embolism, a clottage), disturbance of a cerebral circulation in pool of the general and internal carotids, encephalomyelitises ().
The clottage of the central artery of a retina happens at persons of an average and advanced age, suffering an atherosclerosis, an idiopathic hypertensia. The retinal embolism meets less often than a clottage and is observed, mainly at sick of endocarditises, a sepsis, some infectious diseases. At a clottage and a retinal embolism suddenly there comes blindness (amaurosis), and at an occlusion of its branches - abaissement of sites of fields of vision. In the subsequent the atrophy of an optic nerve and a macula lutea degeneration can develop.
Disturbance of a cerebral circulation in pool of an internal carotid (a clottage, an embolism, a vasomotor spasm) is shown alternating optiko-piramidnym by a syndrome: a sudden amaurosis or a sharp amblyopia on the lesion party, sometimes with an atrophy of an optic nerve which develops later, weakening or absence of reactions of a pupil on light, a hemiparesis or a hemiplegia on an opposite side with a primary lesion of an arm. If the left internal carotid is amazed, there is a motor aphasia, sensitivity disorders. On the amaurosis party it is weakened or there is no pulsation of an internal carotid. order levitra online 50 mg
