Introduction

Meibomitis refers to hordeolum, an acute suppurative inflammation caused by infection of the eyelid glands and hair follicles at the base of the eyelashes. Hordeolum is classified into external and internal types. External hordeolum is usually caused by bacterial infection of the sebaceous glands associated with eyelash follicles. Internal hordeolum typically results from acute suppurative inflammation of the meibomian glands located deep within the eyelid, and requires medical evaluation and treatment.

Meibomian gland inflammation, clinically referred to as blepharitis, is an inflammatory condition caused by infection of the eyelid glands. The specific details are as follows:

Blepharitis is classified into two types: external and internal. External blepharitis is usually caused by bacterial infection of the sebaceous glands associated with hair follicles of the eyelashes. It typically presents with eyelid swelling, itching, and distending pain. A hard nodule can be felt near the eyelid margin, accompanied by tenderness. Internal blepharitis is usually an acute suppurative inflammation of the deeper meibomian glands within the eyelid, manifesting as redness, swelling, and pus formation in the eyelid. A yellowish-gray pus point may appear on the surface.

Patients are advised to undergo relevant examinations at a hospital and follow medical instructions for targeted treatment to promote recovery and restore eye health.

Will the meibomian glands become blocked again immediately after being cleared?

Meibomian gland obstruction may lead to symptoms such as dryness, burning sensation, and foreign body sensation in the eyes. The opening of the meibomian glands should generally be promptly cleared and treated. Since the blockage is caused by gradual accumulation of secretions, the glands typically do not become blocked again immediately after being cleared. However, if eye hygiene remains inadequate after treatment, recurrence may occur.

What is the Meibomian gland?

Meibomian glands are an important component of the eyelid, located within the tarsal plate. The tarsal plate is composed of connective tissue, elastic fibers, and meibomian glands. It contains vertically arranged sebaceous glands known as meibomian glands, which play a role in protecting the tear film by contributing to the integrity of connective tissue, maintaining refractive function, preventing lacrimal fluid overflow, reducing tear evaporation, and avoiding contamination of the tear film by sebum.

Can long-term warm compresses on the meibomian glands be normal?

When meibomian gland function is abnormal, long-term warm compresses cannot restore the glands to normal. Meibomian gland dysfunction leads to tear film instability and reduced secretion of meibum, resulting in dry eyes. Blockage of the meibomian glands can cause meibomian gland inflammation (meibomitis), gradually forming nodules. Although long-term warm compresses can promote blood circulation around the eyes and facilitate the secretion of meibomian gland secretions, providing supportive treatment, they cannot completely cure the condition.

Can Meibomian Gland Dysfunction Be Completely Cured?

Meibomian gland dysfunction can be effectively managed and alleviated through treatments such as warm compresses, massage, and medication. Other options, including surgical intervention, are also available. In daily life, patients should avoid prolonged use of computers and mobile phones, make sure to rest their eyes by closing them or looking into the distance to prevent eye strain. If symptoms occur, patients should seek medical treatment at a hospital as soon as possible.
