Computer modeling may improve understanding of glaucoma

A new mathematical model may help doctors learn more about the risk factors and causes of glaucoma, including the mechanisms affecting blood flow to the eye. The research will be presented today at the American Physiological ...

Potassium balance and glaucoma

Retinal ganglion cells (RGCs) make up the optic nerve. When RGCs degenerate due to elevated intraocular pressure caused by glaucoma, vision is lost.

Novel methods to treat glaucoma

Glaucoma is characterized by degeneration of retinal ganglion cells, leading to irreversible vision loss. Currently, the only treatable glaucoma risk factor is increased intraocular pressure. While lowering this pressure ...

Genetics

Aqueous humor, microRNAs and glaucoma

Glaucoma—the leading cause of vision loss worldwide—includes a heterogeneous group of disorders. Primary open-angle glaucoma (POAG) and exfoliation glaucoma (XFG) are linked to decreased outflow of aqueous humor, which ...

Ophthalmology

Genetic basis for glaucoma uncovered

In two recent publications, Northwestern Medicine scientists and international collaborators discovered mutations that cause improper drainage and a buildup of ocular pressure leading to one form of congenital glaucoma, and ...

Drinking hot tea every day linked to lower glaucoma risk

Drinking a cup of hot tea at least once a day may be linked to a significantly lower risk of developing the serious eye condition, glaucoma, finds a small study published online in the British Journal of Ophthalmology.
