Eyelid and Eyelash Malpositions

  • Lora Dagi GlassEmail author


The upper and lower eyelid structures are similar and analogous, yet distinct, each with a complex anatomy that allows the lids to retain form and function. Anatomic pathology of any cause can disrupt eyelid position, stability, and movement, thus allowing for a range of symptoms including tearing (epiphora), disruption in vision, conjunctival injection, keratopathy, or in extreme cases, corneal perforation. This chapter will briefly review eyelid anatomy, followed by an anatomically based discussion of the etiology and treatment of five common eyelid malpositions – ectropion, entropion, epiblepharon, ptosis, and retraction – as well as a brief review of trichiatic eyelashes.
