Conjunctival congestion exposing yellow pus

Introduction The meibomian glands in the inflamed state are surrounded by firm tarsal tissue. On the surface of the conjunctiva that is congested, the yellow pus is often faintly exposed, and the pus may be worn through the conjunctival sac. Conjunctival hyperemia reveals that yellow pus is one of the clinical manifestations of stye. Stye is commonly known as the pinhole, which is an acute suppurative inflammation of the sebaceous glands or meibomian glands near the eyelash follicles. There are two types of glands in the eyelids, called the sebaceous glands at the root of the eyelashes, which are open to the hair follicles; the other is called the meibomian glands, which are buried in the tarsal plate near the membrane surface, and open at the rim. Stye is an acute suppurative inflammation of these two glands. Most of the bacteria causing the stye are Staphylococcus aureus, so the stye is mostly purulent inflammation.

Diagnosis is based on clinical symptoms.

1, eyelid skin local redness, swelling, heat, pain, adjacent conjunctival edema.

2, 3 to 5 days after the formation of purulent sputum, the appearance of yellow pus. The external stye occurs in the sebaceous glands at the root of the eyelashes, which is manifested in the skin surface; the internal stye occurs in the meibomian glands, which is manifested in the conjunctival surface. After the ulceration and drainage, the pain is relieved, and the redness and swelling subsides.

3, the severe with the ear, submandibular lymph nodes and tenderness, body chills, fever and so on.

The hordeolum is divided into two types, internal and external.

Differential diagnosis

The sputum conjunctiva appears as an off-white membrane: the appearance of an off-white film on the palpebral conjunctiva can be seen in various types of conjunctivitis, usually caused by infectious factors. Due to the leakage, bleeding, and vascularization of the new blood vessels, scars are formed and a permanent mechanical film is formed.

The sputum conjunctiva tears area gray-black mass: sputum conjunctiva tear area gray-black mass is one of the clinical manifestations of palpebral conjunctival melanoma. Melanoma is a malignant tumor of melanocytes derived from the skin, mucous membranes, and pigmented areas of the central nervous system.

The hard and flat nipple of the conjunctiva: due to the clinical manifestations of catarrhal conjunctivitis in the spring, the conjunctival hyperemia is very dramatic at the beginning, and then many hard and flat nipples occur in the upper conjunctiva, varying in size. It is covered with pebbles on the conjunctiva. The crack between the nipples is light blue, and the surface of the nipple presents a milky turbidity. There are not many secretions, it is very sticky, and it is drawn into a filament. For smear examination, it can be seen that eosinophils increase. If there is a lesion in the conjunctiva of the lower jaw, the nipple is small and small, and it is not as prominent as the conjunctiva. Spring vernal conjunctivitis is an allergic disease with a strong seasonality and often invades both eyes. Whenever the spring blossoms, the symptoms disappear and the symptoms disappear when the cold is late in the autumn. Recurrence every year, mild cases will not be issued after 3 to 4 years, severe cases can continue to relapse for more than 10 years. The disease is characterized by itchy eyes, large and flat nipples and conjunctival hyperplasia near the limbus, and a large number of eosinophils in the secretion.
