Meibomian gland dysfunction

MGD may result in evaporative dry eye, blepharitis, chalazion, unsealed lid during sleep, and meibomian gland atrophy.

MGD has been described as "the most underrecognized, underappreciated and undertreated disease in ophthalmic care [...] so common as to be taken as ‘normal’ in many clinical practices".

[6][7] Factors that contribute to the dysfunction can include things such as a person's age and/or hormones,[8] or severe infestation of Demodex brevis mites.

Lifitegrast and Restasis are topical medication commonly used to control the inflammation and improve the oil quality.

[4] Intense pulsed light (IPL) treatments have also been shown to reduce inflammation and improve gland function.

Untreated blepharitis or MGD makes the eyes look red and puffy as if the person have been drinking or have a substance abuse problem.
