What is it?
A chalazion is a chronic sterile inflammatory injury (like a cyst) caused by an oily secretion retained primarily by the Meibomian glands found inside the eyelids. When a chalazion is secondarily infected it is known as internal sty. It can occur at any age and on a recurring basis, and is more common in patients with meibomian pathology or rosacea.
What are the symptoms?
It is usually a painless lesion, but can cause pain if it is inflamed. In very occasional cases a large upper eyelid chalazion can press on the cornea causing astigmatism and blurred vision.
Treatment may be unnecessary because at least one third of the cases resolve spontaneously, and an internal sty may also disappear.
When there are alterations of the glands, with multiple lesions or recurrence of the same, more specific treatments are required with drops or ointments (lubricants and sometimes anti-inflammatory and antibiotic), eyelid massage with heat and food supplements with omega-3.
Persistent encysted injuries that cause discomfort or aesthetically are not accepted by the patient require surgery for removal or a small injection of corticosteroids in the same lesion especially if it is near the lacrimal punctum.
Perform a diet rich in omega 3 fatty acids, as well as a correct eyewash with special wipes paying attention to the inner part of the eyelids (especially the makeup like mascara or eyeliner that directly affect the exit area these glands) are sufficient to prevent the formation of these lesions in cases without palpebral pre-existing pathology.
In patients suffering from disorders of the glands, monitoring by an ophthalmologist it is essential for prevention and correct treatment of chalazions when necessary.
