Eyelid-related illnesses

Blepharitis – Blepharitis is an inflammatory process of the eyelid margin, causing redness and swelling in the area of the eyelid margin, specifically in the follicles and in the glands that are located between them.

Broadly speaking, it is a benign condition but it can cause very annoying symptoms. It involves a wide variety of inflammatory processes, which means that the severity of blepharitis varies considerably between one and the other.

A chalazion is a small, usually painless, lump or swelling that appears on your eyelid. A blocked meibomian or oil gland causes this condition. It can develop on the upper or lower eyelid, and may disappear without treatment.

A chalazion is sometimes confused with an internal or external stye. An internal stye is an infection of a meibomian gland. An external stye is an infection in the area of the eyelash follicle and sweat gland. Styes are usually painful and chalazia usually aren’t. Chalazia may develop after styes. You should see your eye doctor if you think you have a chalazion, especially if it blocks your vision.

Stye – reddish protuberance that appears on the eyelids. Sebaceous gland inflamed on the edge of the eyelid, located next to the eyelashes. It occurs due to a blockage of the gland that facilitates the growth of bacteria or mites within it. It produces eye irritation and a feeling of grit in the eye (foreign body), tearing in the eye and sensitivity to the eyelid among others. It is the most frequent infection of the eyelid. The external stye is caused by infection of the hair follicle of the eyelash. It is usually located on the edge of the eyelid, it is small and superficial. It appears like a granite that produces pain and redness. Adopts the appearance of a small abscess that drains spontaneously and that heals without further complications. The internal stye is produced by the inflammation of a Meibonio gland, located at a greater depth than the hair follicle, so it has drainage difficulties and it is under tension. Therefore, it hurts more and is harder to cure. As a rule, styes are treated with local heat application using a small warm compress, 3-4 times a day and 10 to 15 minutes, and then applying an antibiotic and anti-inflammatory ointment. Occasionally, styes, especially internal ones, tend to become entangled and do not drain, which forces surgical drainage.

Bacterial conjunctivitis – in case of bacterial conjunctivitis, the infection causes an excessive mucous secretion that occurs with a union of the eyelids.
