Adult onset POAG and exfoliation syndrome may have some hereditary tendency, but data is tenuous. C. Myopes are more prone to develop open-angle glaucoma. Hyperopes are more prone to develop angle-closure glaucoma. There is no glaucoma exclusive to any race or ethnic group. However, there are some rough epidemiologic rules.
Pigmentary glaucoma occurs almost exclusively in Caucasians.
Everyone can develop exfoliation syndrome, but it appears to be most common in those of European descent. Diagnosing glaucom a A variety of diagnostic tools aid in determining the presence, absence, or predisposition to glaucoma. Because not all eyes respond similarly to a particular IOP level, a normal pressure cannot be represented as a specific measurement. Therefore, the most that we can expect is to determine their relative chance of developing glaucoma at different pressure levels given the knowledge of the distribution of IOP in general populations and in populations of individuals with glaucomatous damage. In applanation tonometry, the eye is anesthetized with drops and, at the slit lamp, a plastic prism is lightly placed on the cornea.
