Purpose: To describe the histological features of eyelid tissue in involutional ectropion carriers.
Methods: An interventional case series study was performed evolving 52 involutional eyelid ectropion carriers submitted to Tarsal strip surgery. A full-thickness eyelid fragment was evaluated by light microscope and results were statistical analyzed.
Results: The conjunctival substantia propria had an inflammatory mononuclear process. Meibomian glands and eyelash follicles were enlarged. Inflammatory cells permeated the glands and eyelashes follicles. Orbicularis muscle fibers were replaced by fibrosis in some areas. Solar elastosis and epithelial squamous cell metaplasia were also observed in the skin epithelium.
Conclusion: Eyelid ectropion is associated with important lid margin alterations affecting the glands, eyelashes, and orbicularis muscle. Inflammation and fibrosis compromise and disturb eyelid function.
