Influence of eyelid malposition on dry eye
The eyelids protect the eye physically, by blinking, which protects the ocular surface from noxious insult and facilitates tear spreading via secretion of lipids from the meibomian glands. Involutional or iatrogenic eyelid changes can influence eyelid function, potentially leading to dry eye. This r

Lid-wiper staining beats corneal staining for detecting DED
The impact of disease on the ocular surface is often assessed clinically by checking for fluorescein staining of the corneal epithelium, to highlight areas of damage secondary to trauma, infection or desiccation. In dry eye disease, corneal staining is typically superficial, punctate and located inf
