Abstract
Laplace’s law relates the pressure inside a hollow sphere with its radius and the tension in its walls. A theoretical model implementing Laplace’s law in the eye globe is presented. The physical model may help to explain certain aspects in glaucomatous disk damage such as higher susceptibility of myopic eyes to glaucomatous damage and a possible explanation for glaucoma nerve head damage in low tension glaucoma.
