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.
Intrinsic renal causes are also important sources of acute. kidney injury and can be categorized by the component. of the kidney that is primarily affected (i.e., tubular, glo -. merular, interstitial, or vascular). Acute tubular necrosis is the most common type of. intrinsic acute kidney injury in hospitalized patients. The cause is usually ischemic (from prolonged hypoten-. sion) or nephrotoxic (from an agent that is toxic to the. tubular cells).
