Abstract

Glaucoma is one of the ocular diseases which develops when the eye internal fluid cannot drain properly and intraocular pressure builds up. This can result in damage to the optic nerve and the nerve fibers from the retina and early diagnosis is very important as any damage to the eyes cannot be reversed [1]–[3]. Non-contact IOP measurement techniques like corneal response analyzers including CorVis-ST are very popular. The technique depends on impingement of an air puff to the cornea and recording the corneal response to the impact force from the puff using high speed Scheimpflug imaging. The aim of this study is to improve the accuracy of the IOP measurements by considering the fluid structure interaction effect between the cornea, the air puff and the eye internal fluid through a parametric study of numerical models and their comparisons with the clinical data.
