MEDICAL CONDITION
Posterior Ischemic Optic Neuropathy

Anterior ischemic optic neuropathy         
HUMAN DISEASE
Anterior Ischemic Optic Neuropathy; Naion; Optic neuropathy, ischemic; AION; Anterior ischaemic optic neuropathy; Anterior ischemia optic neuropathy; Eye stroke; NAAION
Anterior ischemic optic neuropathy (AION) is a medical condition involving loss of vision caused by damage to the optic nerve as a result of insufficient blood supply (ischemia). This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION), in which the loss of vision is the result of an inflammatory disease of arteries in the head called temporal arteritis, and non-arteritic AION (abbreviated as NAION, NAAION, or sometimes simply as AION), which is due to non-inflammatory disease of small blood vessels.
Ischemic preconditioning         
  • Ischemic preconditioning of the heart (B) provides functional recovery of the heart contractile activity at reperfusion
TECHNIQUE FOR PRODUCING RESISTANCE TO LOSS OF BLOOD SUPPLY
Myocardial ischemic preconditioning
Ischemic preconditioning (IPC) is an experimental technique for producing resistance to the loss of blood supply, and thus oxygen, to tissues of many types. In the heart, IPC is an intrinsic process whereby repeated short episodes of ischaemia protect the [against a subsequent ischaemic insult.
Posterior ischemic optic neuropathy         
Posterior ischemic optic neuropathy (PION) is a medical condition characterized by damage to the retrobulbar portion of the optic nerve due to inadequate blood flow (ischemia) to the optic nerve. Despite the term posterior, this form of damage to the eye's optic nerve due to poor blood flow also includes cases where the cause of inadequate blood flow to the nerve is anterior, as the condition describes a particular mechanism of visual loss as much as the location of damage in the optic nerve.

Posterior ischemic optic neuropathy

Posterior ischemic optic neuropathy (PION) is a medical condition characterized by damage to the retrobulbar portion of the optic nerve due to inadequate blood flow (ischemia) to the optic nerve. Despite the term posterior, this form of damage to the eye's optic nerve due to poor blood flow also includes cases where the cause of inadequate blood flow to the nerve is anterior, as the condition describes a particular mechanism of visual loss as much as the location of damage in the optic nerve. In contrast, anterior ischemic optic neuropathy (AION) is distinguished from PION by the fact that AION occurs spontaneously and on one side in affected individuals with predisposing anatomic or cardiovascular risk factors.
