Development and Analysis of Eyelid Motion Monitoring System for Ophthalmology

DESCRIPTION

The Eyelid Motion Monitor (EMM) is a portable device designed to analyze eyelid movement, critical for diagnosing and monitoring conditions affecting the eyelids and surrounding muscles. This device distinguishes motion in each eye and outputs key parameters such as position, velocity, and frequency. Featuring real-time and offline modes, EMM allows for comprehensive data analysis with a user-friendly interface. Its capability to support multiple devices simultaneously enhances its utility for clinicians managing conditions like ptosis, cataract, and glaucoma.

  2. Background • Opening the eyelid: Levator muscle - Controlled by Occulomotor nerve  Muller muscle - Controlled by the sympathetic system. • Closing the eyelid: Orbicularis muscle is responsible for closing - controlled by the facial nerve (cranial nerve VII) • The functionality of the eyelid is affected by: Damage to one of these muscles or nerves Eye disease (Ptosis, Cataract, Glaucoma) Systemic diseases and physiological changes Degenerative neurologic diseases – management for progressing Topical and systemic medications
