Clinical significance
- normal intraocular pressure (IOP) is 10-21 mm Hg, resulting from the difference between production of & the resistance to drainage of aqueous humor
- there is a diurnal variation in IOP, from 3 - 6 mm Hg
- variation may increase in patients with glaucoma
- during the night, intraocular pressure may not decrease despite slower production of aqueous humour[3]
- elevated intraocular pressure occurs from midnight until 10 AM in patients with open angle glaucoma[6]
- maximal intraocular pressure is at 4 AM
- intraocular pressure is measured by tonometry
- exercise may influence intraocular pressure
- aerobic exercise may decrease intraocular pressure
- weight-lifting may increase intraocular pressure
