Magnetic Correction of Eye Lid Paralysis

Completed · Not applicable

Conditions studied: Blepharoptosis, Lagophthalmos, Facial Paralysis

In brief

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.

Who can join

Age: 5 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Presence of an eyelid movement disorder for at least one eye, moderate cognitive function or better defined as greater than or equal to 18 out of 30 on a pre-screening of the Mini-Mental State Exam, age 5 or older.

You may not qualify if…

• Absence of an eyelid movement disorder or presence of a corneal ulcer. Those with a corneal ulcer are at risk for permanent loss of vision and should be managed with proven methods. Age less than 5, Severe Cognitive impairment defined as Mini-mental score <18, behaviors consistent with delirium (combinations of disorientation, hallucinations, delusions, and incoherent speech), or lethargy. These individuals must be excluded since participation requires competent self-care, reliable responses and cooperation during fitting of the devices.
