Synopsis	Normal-tension glaucoma is not a distinct disorder, but a segment of the spectrum of primary open-angle glaucoma. The difference between normal-tension and high-tension glaucoma lies, for practical purposes, in the proportionate contribution of IOP and risk factors other than, or in addition to, IOP in the causation of optic nerve and visual field damage. We are still faced with problems in diagnosis, workup, and treatment, since we have not elucidated all of the additional risk factors and how they impact the development and progression of glaucoma.
