On a connection of early manifestations of angle closure glaucoma and development of posterior vitreous detachment

: In author's opinion development of posterior vitreous detachment (PVD) is an involutional factor which participates in pathogenesis of primary angle closure glaucoma (PACG) in predisposed eyes. Initial increase of intraocular pressure in the eyes with narrow anterior chamber angle and predisposition to PACG is closely connected with the moment of PVD development, which can be detected with ultrasonography. The author supposes that ultrasonic examination of the posterior globe to detect PVD can be used as one of monitoring method in patients predisposed to PACG.
