Ocular Effects of Gravity Inversion

An examination of the hypothesis that intraocular pressure elevation episodes can have prognostic significance in glaucoma suspects

“…26 The same relationships may be clinically significant for susceptible patients in relation to any other IOP elevating activities. For example, the progression of glaucomatous pathology was found to cease when a patient stopped doing yoga headstands for 5 min every day (with IOP elevations to 40 mmHg), 25 and another patient with glaucomatous changes, beneficially stopped his habit of regularly rubbing his eyes, 60 an activity which is known to elevate IOP to very high levels ( Table 1). Estimating risk of visual field loss in treated patients 43 and assessing factors for glaucoma progression 46 may be improved by the evaluation of histories of participation in IOP elevating activities.…”

The Biomechanics of Keratoconus and Rigid Contact Lenses

“…94 His glaucomatous field losses stabilized after he took advice to desist from these exercises. 94 The case of a 36-year-old man with bilateral keratoconus has been reported, 95 including details of his habit, since childhood, of making his eyes "pop out." He achieved a proptosis of approximately 30 mm by applying finger pressure posteriorly to his eyelids with a squeezing action.…”

“…A case was reported concerning a 61-year-old man who developed glaucoma during a period in which he performed headstand exercises for up to 5 minutes each day. 94 With medication, his IOPs were stabilized at 10 mm Hg, but increases to more than 40 mm Hg were recorded when he assumed his headstand position. 94 In addition, a strenuous flexed muscle posture while sitting, which involved facial congestion, resulted in IOP increases from his baseline of 10 to 25 mm Hg.…”
