Filter by: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.
Lagophthalmos is the inability to completely close the eyelids, which can be caused by conditions such as facial nerve dysfunction and eyelid scarring. Lagophthalmos causes evaporation of the tears, which in turn can lead to damage to the eye and permanent vision loss. Surgical interventions such as tarsorrhaphy or gold/platinum weight implantation can improve lagophthalmos, but these are invasive procedures that are not easily reversible. Temporary methods for treating lagophthalmos are also available, such as the use of medical tape or commercial eyelid closure devices. In the investigators' clinical experience, however, these methods are not well-tolerated by patients due to discomfort, especially due to the device sticking to the eyelashes. As a result, patients are at greater risk of non-compliance and subsequently experiencing ocular complications. The Nictavi Tarsus Patch is a new medical device that uses a flexible material that conforms to the upper eyelid curvature while maintaining sufficient rigidity to keep the upper eyelid in a closed position. It also is designed to be placed above the eyelash line, which allows for enhanced comfort. There has been no study to date evaluating the Tarsus Patch for its effectiveness, safety, or tolerability. The purpose of this study is to determine the effectiveness, safety, and tolerability of the Tarsus Patch in managing lagophthalmos in children and adolescents overnight. The investigators hypothesize that there will be a significant improvement in eyelid closure when using the Tarsus Patch when compared to not using any device and that over 90% of subjects will achieve complete eyelid closure with its use. The investigators also hypothesize there will be no complications related to the use of the Tarsus Patch, and that it will be considered by patients and parents to be comfortable, easy to use, and, overall, preferable to other available methods of nocturnal eyelid closure.
To develop a real-time wearable device based on the principle of magnetic force for temporary management of lagophthalmos, and evaluate its efficacy and safety, including synchronous blinks and eye closure, blurred vision, foreign body sensation over cornea or eyeball, burning or hot sensation over facial skin, and erythema or pruritus over eyelid, by performing a human trial on patients with lagophthalmos.
Traumatic brain injury, stroke and other neurological conditions may result in weakness of the muscles that either open or close the eye. This is generally a result of impaired functioning of the oculomotor or facial cranial nerves. Current treatments to improve eye opening or closing are either invasive or largely ineffective. This study tests a noninvasive means of improving eyelid opening and closing by applying a previously demonstrated safe and effective neuromuscular electrical stimulation (NMES) intervention to the muscles controlling eyelid movement. Participants in this study will either receive the investigational NMES protocol 30 min per day for five days or a sham NMES for the same period. The primary outcome for this study is the participants' ability to open or close their affected eye. Secondary outcomes include additional measures of eye and corneal health.
Objective 1: Determine the safety and feasibility of externally mounted magnets for extended management of chronic eyelid movement disorders by measuring visual acuity and corneal and skin integrity and comfort over 8 weeks of wear. Objective 2: Collect preliminary data on the relative efficacy of external magnetic devices by comparing them to externally mounted lid weights and ptosis crutches using rating scales and video analysis of blink biomechanics.
