PURPOSE Metabolic syndrome denotes a common cluster of naturally connected risk factors including obesity, elevated blood pressure, insulin resistance, dyslipidemia, proinflammatory state and prothrombotic state. Anterior ischemic optic neuropathy is an acute ischaemic disorder of the optic nerve head and may lead to severe visual loss. METHODS We considered three patients with moderate degre...

BACKGROUND Nonarteritic ischemic optic neuropathy is characterized by sudden and painless loss of vision in one eye, accompanied by pallid swelling of the optic disc.

BACKGROUND Ischemic optic neuropathy (ION) is a rare but devastating complication of surgery. It has traditionally been associated with intraoperative hypotension in patients with underlying arteriosclerosis. METHODS We present a case of ION following bilateral neck dissections in which there was minimal intraoperative hypotension and preservation of both internal jugular veins. The potential...

INTRODUCTION An "overlap syndrome" is defined as the sequential appearance over time of two or more risk factors for glaucomatous damage. The appearance of a new risk factor can alter the course and prognosis of previously stable disease. Exfoliation syndrome is a leading cause of glaucoma and is associated with vascular disease. We report a case of central retinal artery occlusion and non-arte...
