Medical hypothesis discovery and innovation in ophthalmology

Abstract

Tactile palpation is a simple technique that can prove useful for estimating intraocular pressure (IOP) in primary healthcare settings, mainly in the absence of equipment, for very young children, patients who are intellectually challenged, those with eyes with extremely irregular corneas, and patients with corneal prostheses. Accordingly, this technique can also aid in the diagnosis of high IOP in primary and emergency care settings. To the best of our knowledge, there is no instrument that can quantify the estimation of IOP and teach tactile examiners. This group has developed a digital instrument called the MEHDI-IOP Measurement Model to train primary healthcare workers as well as blind individuals in the estimation of IOP. In this simple instrument, elastic spheres with a specific inner pressure can be touched and the responses of candidates with regard to the estimated pressure can be graded accordingly.
