semipurposeful avoiding movements. They have normal pupils, corneal
reflexes and plantar reflexes. They may keep their eyes firmly shut
and resist the opening of the eye by examiners. Because eyelid tone
cannot be changed at will, in patients with true coma passive eyelid
opening is easy and is followed by slow eyelid closure. Blinking also

opening the eyes of a person who is awake produces miosis. The eyes
roll up when the lids are raised, known as Bell's phenomenon as
