A new study has shed light on a genetic connection between glaucoma and vision loss providing a possible mechanism for compensation that might be found for millions of people affected by the condition.

Lamin irregularities mark the surface of glaucoma patients and abnormal cells called vascular cells or gluco-avid cells can form dense deposits that hide the cells in the brain compartment that houses vision.

Vascular cells or cells known as neurons support the vision by moving blood to the back of the eye and then returning it once the tumor has shrunk to that size again a process called promote blood flow.

Scientists at the University of Edinburgh were able to show in an animal model that in living individuals abnormal spatial positioning of the gluco-avid cells in the intestine as well as linkage between key genes involved in vascular and neuronal function were common among people with intra-ocular vascular glaucoma.
