Generic Drug to Treat and Prevent Macular Degenerative Diseases

UW–Madison researchers have identified a new treatment option for a number of macular degenerative diseases including AMD, Stargardt’s disease and juvenile macular dystrophy.

The researchers found that a class of compounds called acid sphingomyelinase inhibitors can be used to fight retinal disorders associated with abnormal accumulations of lipofuscin (a cellular waste product), cholesterol or increased inflammation. One such inhibitor, generic name desipramine, is currently sold on the market as an antidepressant. Other acid sphingomyelinase inhibitors also may be suitable.

Method for Reducing Intraocular Pressure Using Integrin-Linked Kinase Inhibitor

UW-Madison researchers now have developed a method of treating increased intraocular pressure by administering agents that interfere with activities of integrin-linked kinase. Interfering with the ability of ILK to couple integrin signaling to the actin cytoskeleton increases aqueous humor outflow through the trabecular meshwork and decreases intraocular pressure. A PI3K inhibitor can be administered with the ILK inhibitor to further reduce intraocular pressure.
