A patient is presenting with a non-painful swelling on the eye-lid as shown in the image.This condition occurs due to obstruction of which glands?
A. Zeis gland
B. Moll glands
C. Manz glands
D. Meibomian glands
Ans:D. Meibomian glands
Condition shown is Chalazion
- It is a chronic noninfective granulomatous inflammation of the sebaceous glands of the eyelid. They commonly affect the meibomian glands in the tarsal plate, resulting clinically as a painless, firm nodule of the eyelid.It occurs due to due to blockage and swelling of meibomian glands.
- Histologically, deep dermal or subcutaneous suppurative lipogranulomatous inflammation exists, containing neutrophils, plasma cells, lymphocytes, histiocytes, and giant cells in a zonal configuration around central lipid material. A pseudocapsule surrounds the cellular infiltrate.
- Conservative treatment with lid massage, moist heat, and topical mild steroid drops .Intralesional steroid injection may also be used. These aid in reducing inflammation and increasing the local blood supply.
- Antibiotics are usually unnecessary.
- Incision and curettage is a conventional and effective treatment of chalazion
- A chalazion clamp is applied to evert the lid and to control bleeding. A transconjunctival vertical incision is made (to avoid injury to other meibomian ducts)
- If a chalazion threatens to break through the skin or has drained through, an external approach may be recommended. A horizontal incision is made in the skin (to have an invisible scar) at least 3 mm from the lid margin in an existing crease.
