Conjunctival papillary hyperplasia

Introduction Conjunctival papillary hyperplasia: a large number of conjunctival epithelial cells proliferating, accompanied by vascular proliferation and inflammatory cell infiltration caused by local lesions of the conjunctiva, punctate or small globular bulge, the surface of the conjunctiva under the naked eye is velvet-like, not smooth, slit lamp organism The umbilical neovascularization is visible in the center of the nipple under the microscope, making the nipple red. The inflammation is severe and delayed, and the adjacent nipples can be fused to form a giant nipple with a diameter greater than 1 mm. Nipple hyperplasia is a non-specific change of the conjunctiva, more common in allergic conjunctivitis, spring catarrhal conjunctivitis, giant papillary conjunctivitis (reaction to contact lens, artificial cornea and long-term corneal foreign body), as well as trachoma and chronic conjunctiva inflammation. Conjunctivitis is a common disease in ophthalmology, but its incidence has not yet been determined. Since most of the conjunctiva is in direct contact with the outside world, it is susceptible to infections (such as bacteria, viruses, and chlamydia) and non-infectious factors (trauma, chemical and physical factors) in the surrounding environment, and the blood vessels of the conjunctiva and Lymphatic tissue is abundant, and its own and external antigens tend to cause sensitization. Conjunctivitis is a general term for the inflammatory reaction of conjunctival tissue in the external and internal factors. Although conjunctivitis itself is generally not severely affected by vision, it can cause vision damage when its inflammation affects the cornea or causes complications.

Cause

The etiology of conjunctivitis is mainly divided into two types, infectious and non-infective. Infectious causes mainly include: viruses, bacteria and chlamydia, fungi, spirochetes and parasites are rare. The main causes of non-infectious include: immune factors, chemical substances, physical factors and systemic disease factors.

Conjunctivitis is generally mild, but once it develops, it is treated immediately to avoid complications. The doctor will ask about the medical history, symptoms, and medications and perform a slit lamp microscope. Chronic conjunctivitis: Chronic conjunctivitis is a chronic inflammation of the eye. Allergies and environmental factors are the cause of the disease. The course of the disease can last for weeks or months. The treatment measures include reducing symptoms and avoiding possible factors.

1. Allergies. Flowers, pollen, dust, mold and animals are common causes of eye allergies, which can cause eye irritation, itchy eyes, swelling and other discomforts, mostly for binocular attacks. The best way to treat allergic chronic conjunctivitis is to avoid sensitizing substances and the environment. Cold application and dripping with eye drops can reduce swelling, redness and itching. If your symptoms are severe, your doctor may give you an oral medication, usually the symptoms will last for weeks.

2. Environmental factors. Air pollution, smoke, improper contact with corneal contact lenses, irritating gases, chemicals, etc. can cause conjunctival inflammation, which can affect single or both eyes. The best treatment for conjunctivitis due to adverse environmental factors is to improve the working and living environment. If you have dry eyes, use artificial tears to moisturize the eyeballs and clean the conjunctiva. Other eye drops can also be used to reduce swelling and itching. Acute conjunctivitis: Acute conjunctivitis is caused by bacteria and viruses. The incidence is more urgent, the course of disease is short, and acute conjunctivitis is suffered. You should wash your eyes and wash your hands frequently, or you can drop eye drops or cold compresses.

Differential diagnosis

Examination revealed redness and swelling of the eyelids, conjunctival hyperemia, nipple follicular hyperplasia, peripheral conjunctival hyperemia, sometimes edema and subconjunctival hemorrhage, and secretions in the conjunctival sac. To determine the source of the disease, a secretion smear is required for bacterial and cytological examination.

1. If necessary, conjunctival epithelial scraping and secretion smear or culture to check bacteria, fungi, virus isolation, etc., and do drug sensitivity test.

2. For those with irritation, check the cornea with fluorescein staining.

3. Epidemiological investigations should be conducted when necessary.

4. For chronic conjunctivitis should be asked: whether there is ametropia, excessive alcohol and tobacco, lack of sleep or long-term exposure to sand, smoke and other medical history. Check for chronic inflammation in nearby tissues, such as chronic dacryocystitis.
