Intraocular pressure fluctuation: Is it important? [PDF]
Journal of Ophthalmic & Vision Research, 2018 Elevated intraocular pressure (IOP) is a major risk factor for the development and progression of glaucoma. Previous prospective, randomized, long-term studies have demonstrated the strength of IOP reduction in slowing the progression of disease.
