Abstract

This study evaluated a new method for measuring intraocular pressure (IOP) in the vitreous cavity. IOPs in the anterior chamber and vitreous cavities of 24 porcine eyes (12 with lenses, 12 without) were measured simultaneously and continuously. A significant interaction between vitreous cavity IOP, lens presence (phakia/aphakia), and anterior chamber IOP was observed. Vitreous cavity IOP correlated positively with anterior chamber IOP in both groups, but the difference between them (ΔIOPv-a) did not correlate with anterior chamber IOP. The new sensor accurately measured vitreous cavity IOP, even in the presence of vitreous gel.
