The Glaucoma Foundation funds research initiatives to determine the causes of glaucoma, to improve methods of treatment, and, ultimately, to develop cures for the various kinds of glaucoma.

Three areas of particular focus in TGF's Grant-In-Aid program are:

Optic nerve rescue and restoration
Research into new approaches designed to protect the optic nerve against glaucomatous damage, to restore vision lost to glaucoma and eventually reverse blindness by restoring or regenerating the function of the optic nerve cells, and to explore the feasibility of achieving transplantation of optic nerve cells.

Molecular genetics
Research into the genetic causes of the various forms of glaucoma, particularly the identification of the responsible genes, with the longterm goal of finding ways to reverse these genetic defects.

Nanotechnology
Research into the use of nanotechnology for IOP monitoring, drug delivery, and detection.
