part of the development of a novel management technique for unilateral lagophthalmos.

About the Book

A novel management technique for unilateral lagophthalmos is being developed that will alleviate keratitis (severe corneal inflammation, irritation and infection) by restoring a complete and synchronous blink to the paralytic eyelid. The development of this technique involves two phases; blink detection of the functioning eyelid to ensure a synchronous blink and functional reanimation of the paralytic eyelid.This work reports on the successful completion of the blink detection system. A non-contact infrared blink detection device was developed which is capable of successfully detecting 95.5% +/- 3.56% of blinks for five test subjects in three ambient lighting conditions; inside, outside in complete shade and direct sunlight. In addition to reliably operating in varying ambient lighting environments, the system was developed to be minimally obtrusive, portable and able to accommodate varying facial geometries with no system adjustments. These design specifications were implemented to enhance the blink detection system's clinical acceptability.
