Intraocular pressure fluctuation during resistance exercise

Diurnal Fluctuation of Intraocular Pressure.

Diurnal fluctuation of intraocular pressure (IOP) is an important issue in managing glaucoma, yet its bases are not well understood. Delineating the genetic controllers and physiological pathways may open the door to potential therapeutic targets. Miller and associates have provided evidence for a GPR18 role in the diurnal regulation of IOP in mice and explored the related endocannabinoid pathw...

Intraocular pressure during phacoemulsification.

PURPOSE To assess changes in intraocular pressure (IOP) during standard coaxial or bimanual microincision phacoemulsification. SETTING Oregon Eye Center, Eugene, Oregon, USA. METHODS Bimanual microincision phacoemulsification (microphaco) was performed in 3 cadaver eyes, and standard coaxial phacoemulsification was performed in 1 cadaver eye. A pressure transducer placed in the vitreous cav...

Diurnal Intraocular Pressure Fluctuation in Eyes with Angle-closure

PURPOSE To investigate diurnal intraocular pressure (IOP) fluctuation in eyes with angle-closure. MATERIALS AND METHODS Seventy-seven eyes of 77 newly diagnosed patients with angle closure [33 subjects with primary angle-closure suspects (PACS), 23 subjects with primary angle-closure (PAC), and 21 subjects with primary angle-closure glau-coma (PACG)] were enrolled after laser peripheral irido...

Experimental closed system surgical procedures and intraocular pressure fluctuation.

PURPOSE To determine the behavior of intraocular pressure and its relationship with infusion pressure in vitrectomy, phacofragmentation and phacoemulsification surgeries in rabbits. METHODS Intraocular pressure fluctuation was measured in 24 eyes of 12 rabbits submitted to vitrectomy, phacofragmentation and phacoemulsification procedures (eight eyes per group). The procedures were divided acc...
