Science Daily "Glaucoma is the leading cause of blindness among blacks, affecting close to five percent of the population. The researchers chose to conduct the study in the Afro-Caribbean population of Barbados, where the incidence of glaucoma is double that figure – nearly 10 percent of all residents of the island – and where there is a strong genetic predisposition.
Known as 'the silent thief of sight,' glaucoma is a neurodegenerative disease that causes the death of ganglion cells of the retina, resulting in gradual and irreversible loss of peripheral vision. Reducing intra-ocular pressure can slow the progression to blindness, but there is no cure or reversal for glaucoma."
