The TFOS International Workshop on Contact Lens Discomfort: Report of the contact lens interactions with the ocular surface and adnexa subcommittee

摘要

The ocular surface consists of the continuous mucosal surface that begins with the cornea centrally and extends, via the limbus, to the bulbar and fornical conjunctiva to end with the tarsal conjunctiva.1,2 Classically, the tarsal conjunctiva is further subdivided into proximal and distal parts by the presence of a subtarsal fold,3 which runs parallel to the lid margin at approximately 2 mm from its posterior border. The distal part, termed the marginal conjunctiva, is of particular importance to lid function during blinking and extends from the fold to the mucocutaneous junction on the occlusal surface of the lid margin. That part that is apposed to the globe is the site of the so-called “lid wiper” zone of the lid, which has an important role in distributing the tear film across the ocular surface.
