Walsh and Hoyt's Clinical Neuro-Ophthalmology

Normal and Abnormal Eyelid Function

"Disorders of neuro-ophthalmologic significance may affect not only visual sensory, ocular motor, and pupil function but also the function of the eyelids."

"Disorders of neuro-ophthalmologic significance may affect not only visual sensory, ocular motor, and pupil function but also the function of the eyelids. Indeed, the inability of a patient to fully open or close his or her eyelids may be the first sign of a more extensive process, the early diagnosis and treatment of which may be crucial to the ultimate well being of the patient. This chapter describes the elements that make up a complete assessment of eyelid function, the anatomy of the structures that provide normal eyelid function, and the various pathologic processes that impair eyelid opening and closure."
