A glaucoma characterized by shallowing of the central and peripheral anterior chamber from posterior pressure such that the intraocular pressure becomes inappropriately elevated leading to optic nerve damage and visual field loss. Aqueous misdirection has_symptom progressive peripheral vision loss, decreased vision, and pain, redness, and headache in acute cases. Aqueous misdirection is caused by an abnormal relationsihp between the ciliary body, lens, and anterior vitreous such that aqueous flow is diverted into the posterior segment, leading to increased posterior pressure, which further closes the angle. Aqueous misdirection may occur in association with glaucoma surgery, trauma, endophthalmitis, and retinopathy of prematurity.
