Abstract

Retinal detachment is a serious condition that most commonly occurs in the elderly; if left untreated, it can lead to complete or partial blindness [1]. Rhegmatogenous retinal detachment is the most common type of detachment of the retina. It occurs due to a tear in the retina that allows the passage of the vitreous to the space between the retina and the choroid [2]. In order to make sure that the retinal detachment does not progress to the macula, reducing or stopping the growth of the retinal detachment is vital in the period between diagnosis and surgery [3]. However, it is not known what loads on the eye contribute the most to retinal detachment progression. This study aims to identify the role of head movements and saccadic movements on retinal detachment progression. This has been done by creating a finite element model that includes all the eye components with assigned material properties. A mesh convergence study was carried out to identify the optimum mesh for the study. Primary results showed that saccadic eye movements apply less stress on the retina than head movement. Moreover, the results show that the size of vitreous detachment is proportional to the extent of retinal detachment. A new experimental ... (continues)
