Standing on your head or playing loud, high-pitch notes on a trumpet can elevate intraocular pressure, according to Professor Charles McMonnies.

The IOP elevation levels recorded during common activities such as eye-rubbing, or wearing swimming goggles or a tight necktie may contribute to glaucoma development or progression as well as stretching of the fundus and myopic pathology, he says.

His review paper titled ‘The relation between IOP, fundal stretching and myopic pathology‘ is published in Clinical and Experimental Optometry.

‘When scleral compliance is sufficiently elevated, axial elongation in association with normal-range IOP suggests that episodes of elevated IOP, which occur during common activities such as prone-position sleep, eye rubbing and strenuous physical exercise would have the potential to exacerbate elongation and stretching of the fundus,’ Professor McMonnies wrote.

‘The significance of such activities and the associated IOP elevations would appear to depend on the degree, duration and frequency of elevation episodes as well as the period over which they occur.’
