Self-Adhering Magnetic Device to Treat Corneal Exposure
University of Illinois at Chicago
Summary
Paralytic lagophthalmos can be difficult to treat and manage. It has a host of causes and effects, one of which (for the latter) is exposure keratopathy. Untreated, this can lead to corneal ulceration, inflammation, and potentially blindness. Despite a variety of attempts at treating this complex condition, none have satisfactorily reduced complications ranging from ease of use to aesthetics. With improvement in magnetic technology, however, that may change. Barmettler et al (2014) have demonstrated preliminary success of externally affixed magnets in closing both model and patient eyelids. As such, we hypothesize that magnetic devices can be used to treat corneal exposure by controlling eyelid position.
Description
Patients who suffer from lagophthalmos cannot close their eyelids completely. In paralytic lagophthalmos, this physical incapability is caused by paralysis of the seventh cranial nerve. Causes of this paralysis include Bell's palsy, vascular accidents, injury, trauma, and tumors. Complications can include irritation, ulceration, and perforation of the cornea; exposure and neurotrophic keratopathy; persistent epithelial defects; and potential blindness. Due to the myriad causes and complications, management of paralytic lagophthalmos has proven difficult, and existing methods of treatment each…
