The finite element analysis of the pathology and treatment of high myopia esotropia

High myopia esotropia is a kind of special strabismus whose pathology is still uncertain. In this paper, the finite element analysis method is applied to examine some physiological hypotheses by modeling the movement of the eyeball and morbid extraocular muscles. The model stems from clinical data. Theoretical analyses are also performed to examine the effect of oblique pulley. Finally, postoperative eyes are simulated to examine the clinical operation criterion. The results show that the distorted initial eye position and weakness of relative muscles may be the main etiology.
