What causes glaucoma?
New research study has found that in the optic nerve head, astrocytes have accumulated abnormal forms of gamma synuclein a protein that is similar to abnormal forms of alpha synuclein( responsible for Parkinson's disease). Removal of the debris of one cell by a neighboring cell occurs in glaucoma and Parkinson's disease.
