Abstract: 【Abstract】The aqueous humor dynamics involves the aqueous humor formation and outflow resistances through the trabecular meshwork and uveoscleral pathways. All those parameters including coefficient of outflow facility, aqueous outflow,  uveoscleral outflow take part in determining the level of the intraocular pressure. The aqueous humor dynamics attract more attention nowadays with the progressions in understanding the mechanisms of glaucoma and ocular hypertension. The thinner corneas of the Black patients may be masking potential differences in aqueous humor dynamics between the Black and White subjects with glaucoma. The healthy aging eyes have reduced anterior chamber volume, reduced aqueous flow and uveoscleral outflow. The increased intraocular pressure in ocular hypertension is caused by a reduction in coefficient of outflow facility and uveoscleral outflow. Patients with pigment dispersion syndrome and with exfoliation syndrome experience higher intraocular hypertension and lower coefficient of outflow facility as well.
