Treatment of total hyphemas with urokinase

American Journal of Ophthalmology
D M Leet


Total hyphemas were created by aspirating the aqueous humor from the anterior chambers of rabbit eyes and then injecting human blood. Thirty-six of these eyes were then treated with urokinase. A control group of 26 eyes was treated with normal saline. Nine eyes with total hyphemas were left untreated. The untreated eyes had uniformly bad results with prolonged elevation of intraocular pressures, marked ciliary injection, and corneal vascularization. The normal saline control eyes cleared faster than the untreated eyes, probably because of the mechanical dissolution of the clot with irrigation or injection. However, these control eyes showed significantly poorer results than the enzyme-treated eyes. The eyes treated with urokinase, whether injected or irrigated, had a marked increase in the rate of absorption of clot and less fibrin formation in the anterior chamber. Intraocular pressures returned to normal much sooner in these eyes than in untreated eyes, and most corneas cleared completely.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
