Can you explain the difference between primary or secondary closed angle glaucoma? are they both hereditary? my mom has it and had terrible vision her whole life.. i had good vision and never wore glasses, am i still at risk of this?

Primary closed angle glaucoma: you are born with the eye anatomy which can develop into this condition with aging. This probably has genetic link but the incidence is unknown, more prevalent in population of Asian descent. Secondary closes angle glaucoma: a primary process (a different eye disease, e.g. retinal bleeding) is responsible for narrowing or closure of the anterior chamber angle.
