Eye twitching in myasthenia gravis occurs because the immune system affects the connection between nerves and muscles in your eyes. The extraocular muscles (muscles that control eye movement) are particularly susceptible to weakness and fatigue in MG because they:
• Contract more rapidly than other muscles in the body
• Are constantly active when you're awake
• Have structural differences making them more vulnerable You may notice specific patterns with eye twitching:
• Twitching when looking down for extended periods
• The "curtain effect" where one eyelid droops when lifting the other
• Twitching that improves after rest
• Twitching that may affect one or both eyes
If twitching significantly affects your vision or daily activities, it's important to discuss this with your healthcare provider as they can recommend appropriate management strategies.
