At 0:43, are you SURE there is a part of conjunctiva that's over the cornea?? Here's what I find at StatPearls: "The palpebral conjunctiva lines the eyelids. The bulbar conjunctiva is found on the eyeball over the anterior sclera. " And, " The conjunctiva covers the anterior, non-corneal portions of the globe, as well as the fornices and the palpebrae." www.ncbi.nlm.nih.gov/books/NBK519502/
