Open-angle glaucoma. Chronic open-angle glaucoma is the most common form of glaucoma. The open drainage angle of the eye can become blocked leading to gradual increased eye pressure. If this increased pressure results in optic nerve damage, it is known as chronic open-angle glaucoma.
Acute tubular necrosis. Acute tubular necrosis (ATN) is a medical condition involving the death of tubular epithelial cells that form the renal tubules of the kidneys. ATN presents with acute kidney injury (AKI) and is one of the most common causes of AKI. Common causes of ATN include low blood pressure and use of nephrotoxic drugs.
Structural changes of cells undergoing necrosis and apoptosis. Necrosis (from the Greek Î½Î­ÎºÏÏÏÎ¹Ï death, the stage of dying, the act of killing from Î½ÎµÎºÏÏÏ dead) is a form of cell injury which results in the premature death of cells in living tissue by autolysis.ntreated necrosis results in a build-up of decomposing dead tissue and cell debris at or near the site of the cell death. A classic example is gangrene.
