Ocular motility analysis in patients with anophthalmia using digital image processing techniques

Abstract

The anophthalmia is an eye disease identified by the absence of this, and its solution requires not only a coupled prosthetic eye but also a surgery to generate motility. Pre, post-operative and rehabilitation results of eye motility are required by health specialists. However, the motility analysis techniques currently used, provide only a qualitative evaluation. This paper presents a systematic tool to quantify ocular motility in lateral, nasal, upper and lower eye movements, with the help of image acquisition and digital processing techniques. An interface that also allows relating pre and postoperative patient data, as well as, relevant data to the process of rehabilitation, was developed by the authors. This diagnostic tool created as part of this research is noninvasive, the test time is shorter and more comfortable in comparison to currently used techniques and tools, and provides a measurable value of improved prosthetic motility patient's eyeball. This tool development was verified on patients with unilateral anophthalmia with age between 7 and 15 years old at Clínica de Oftalmología in Cali, Colombia.
