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.
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…
Inclusion Criteria: * Males and females ages 18-80 years old. * Patients with recent corneal abrasion and no signs of infection in the examination * Patients with lagophthalmos * Normal Controls Exclusion Criteria: * Individuals with adhesive or tape allergies. * Individuals with a history of metal pieces/shavings embedded in the eye (such as from welding or metalworking) * Individuals with eye infections
cutting-edge technology has produced smaller magnets with stronger magnetic fields, prompting experts to revisit the use of magnets to facilitate eyelid closure
