What causes eye pain? Several common causes

Common causes of eye pain in the corners of the eyes are fatigue and styes. Fatigue is related to frequent computer use, which is also the main cause of eye pain in young people today. If it is a stye, it will be accompanied by symptoms of redness, swelling and heat, and requires timely examination and treatment.

1. What causes eye pain?

First of all, it should be emphasized that this is not due to fatigue, but is definitely caused by a virus or bacterial infection, but it may be related to playing computer games (because people's resistance will decrease at night).

If the pain is on the upper outer corner of the eye or above the eyelid, it may be a stye or a chalazion (or stye). If a small red lump develops there two days later, it is a symptom of a stye. Otherwise it should be the other two mentioned above.

2. Symptoms of stye

1. Symptoms

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

(2) After 3 to 5 days, a pustule forms and a yellow pus head appears. External hordeolum occurs in the sebaceous glands at the root of the eyelashes and manifests itself on the skin surface; internal hordeolum occurs in the meibomian glands and manifests itself on the conjunctival surface. After the ulcer breaks and pus is discharged, the pain is relieved and the redness and swelling subside.

(3) In severe cases, there are enlarged and tender preauricular and submandibular lymph nodes, chills, fever, etc.

2. Classification: Hordeolum is divided into two types: internal and external.

(1) Hordeolum externum is an acute suppurative inflammation of the gland of Zeis. At first, the eyelid margin is locally congested and swollen, and a nodule can be felt near the eyelid margin. The swelling, pain and tenderness are obvious. After a few days, the nodule gradually softens and a yellow pustule forms at the root of the eyelashes, which breaks through and discharges pus and heals quickly. If the pathogen is highly toxic, it can cause congestion and edema of the eyelids and nearby conjunctiva, and even eyelid cellulitis, as well as enlarged and tender preauricular lymph nodes, especially in the lateral canthus. Severe cases may have systemic symptoms such as chills and fever.

(2) Hordeolum interunm is an acute suppurative 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 meibomian tissue. Yellow pus is often faintly visible on the surface of the congested palpebral conjunctiva, and may break through and discharge pus into the conjunctival sac on its own. There may be a slight bulge and congestion at the opening of the meibomian gland, and pus may be discharged along the meibomian gland duct. In a few cases, pus may be discharged from the skin through the duct. If the tarsal plate cannot be penetrated and the pathogen is highly toxic, the inflammation will expand, invade the entire tarsal plate tissue, and form an eyelid abscess.
