Eye bags have blister-like appearance

Nowadays, mobile phones are very important tools and are around people almost all the time. If you look at the phone for a long time, something like a blister will grow around your eyes. This thing is commonly known as stye in medicine. It is caused by inflammation in the body. Stye is divided into internal stye and external stye. Stye must be resolved in time, otherwise it will infect the area around the eyes, and in severe cases it can cause blindness.

Stye, also known as sty and hordeolum, is an acute suppurative inflammation of the sebaceous glands or meibomian glands near the eyelash follicles. There are two types of styes: internal sty and external sty:

1. External stye

It is an acute suppurative inflammation of the Zeis gland. Initially, the eyelid margin shows localized congestion and swelling, and a nodule forms after 2 to 3 days. There is obvious swelling, pain and tenderness. Later, the nodule gradually softens and a yellow pustule forms at the root of the eyelashes, which breaks through and discharges pus quickly. Severe cases may have systemic symptoms such as chills and fever.

2. Internal stye

It is an acute purulent inflammation of the meibomian glands. Its clinical symptoms are not as severe as those of external hordeolum, because the inflamed meibomian glands are surrounded by firm tarsal plate tissue. Yellow pus masses are often faintly visible on the surface of the congested palpebral conjunctiva, which may rupture and discharge pus into the conjunctival sac on their own. The opening of the meibomian glands may be slightly raised and congested, and pus may also be discharged along the palpebral gland duct. A few cases may rupture and discharge pus from the skin. If the tarsal plate fails to rupture and the pathogen is highly toxic, the inflammation will expand, invade the entire tarsal plate tissue, and form an eyelid abscess.

Causes

There are two kinds of glands on the eyelids. The sebaceous glands at the root of the eyelashes open into the hair follicles. The meibomian glands are buried in the tarsal plates near the conjunctival surface and open into the eyelid margins. Stye is an acute suppurative inflammation of these two glands. The bacteria that cause styes are mostly Staphylococcus aureus.

Clinical manifestations

1. Localized redness, swelling, heat and pain on the eyelid skin, and edema of the adjacent conjunctiva.

2. When pus accumulates locally, yellow pus heads appear. External styes occur in the sebaceous glands at the root of the eyelashes and appear on the skin surface; internal styes occur in the meibomian glands and appear on the conjunctival surface. After rupture and drainage of pus, the pain is relieved and the redness and swelling subside.

3. Severe cases are accompanied by enlarged and tender preauricular and submandibular lymph nodes, general chills, fever, etc.

examine

1. Pay special attention to changes in the eyelids.

2. If there are systemic reactions, the peripheral blood leukocyte count and classification should be checked.
