Study Summary

This clinical trial will evaluate two non-surgical devices designed to improve eye lid opening for patients with severe Blepharoptosis (incomplete opening of the eyelids).

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Presence of ptosis for at least one eye which occludes the visual axis in theresting position (without frontalis drive, lifting with forehead muscles)

  • 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 (MMSE)

Exclusion

Exclusion Criteria:

  • Absence of ptosis which occludes the visual axis

  • Presence of a corneal ulcer of any size

  • Age less than 5 years

  • Severe Cognitive impairment defined as MMSE score less than 18, behaviors consistentwith delirium (combinations of disorientation, hallucinations, delusions, andincoherent speech), or lethargy.

  • Presence of corneal hypoaesthesia;

  • Orbicularis weakness on the side of the ptosis

  • Mechanical ptosis, including ptosis due to orbital or lid tumor, cicatricialprocesses affecting the movements of the upper lid, and enophthalmos.

  • Previous ptosis surgery less than 3 months prior to Visit 1.

  • Lid position affected by lid or conjunctival scarring.

  • History of herpes keratitis.

  • Periocular neurotoxin (eg, Botox, Xeomin, Dysport, Myobloc) injections on the sideof the ptosis within 3 months prior to Visit 1 and during the study.

  • History of hyperthyroidism or thyroid eye disease (ie, exophthalmos, upper eyelidretraction, diplopia secondary to extraocular muscle involvement). Hypothyroidismthat is controlled on medication is allowed

Study Description

Two non-surgical devices for patients with Blepharoptosis will be evaluated. The Magnetic Levator Prosthesis (MLP), is an external device that makes use of a newer class of permanent magnets (made of alloys of neodymium (Nd), iron (Fe) and boron (B)) to restore eyelid movement. The Kinesiotape Frontalis Sling (KTFS), involves the use of tape to help facilitate levator muscle contraction to open the eyelid. Video recordings of spontaneous and volitional blinks will be used to evaluate the effects of each device on eyelid reanimation.

The clinical trial will employ a crossover design in which participants will try each device at home in counterbalanced order with a washout period between. In each period of the crossover, participants will receive training (during study visits at Massachusetts Eye and Ear) in how to apply the device and will then try the device at home for one week with daily follow up by video calls. At the end of the one-week period of home use there will be a study visit at Massachusetts Eye and Ear when the device will be returned and additional video recordings of eye blinks will be made.

At the end of the crossover period, participants will be asked to complete a questionnaire comparing the two devices and to select their preferred device.
