Lid Margin/ ntermarginal strip
The lids are covered anteriorly by skin and posteriorly by conjunctiva. The margin or free edge of the lid between anterior and posterior borders is called intermarginal strip.Intermarginal strip is covered by stratified squamous epithelium and divided into anterior and posterior part by a gray line. The eyelashes originate anterior to the gray line. The ducts of the Meibomian glands open in a single row posterior to the gray line. The gray line is important as the lid is split at this level.
