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.
Summary. 1  Acute renal failure is common in hospitalized patients. 2  Early recognition is important but still elusive. 3  Acute renal failure results in substantial morbidity and mortality.  Intrinsic acute renal failure is the most common cause; acute tubular necrosis is the most common intrinsic acute renal failure.
