To phacogenic open-angle glaucomas include three different diagnoses with similar clinical symptoms. Facial glaucoma, glaucoma lens masses and phacogenous uveitis (FGU) develop with intraocular inflammation, an abnormal lens and with increased intraocular pressure, but in the future, as a rule, hypotension develops. Differentiation of these three pathologies requires careful examination and understanding of the mechanisms that determine the development of each disease.
