What is the reason for dry, itchy and painful corners of the eyes

Dry and itchy eyes are a problem that many people have. If the dry and itchy eyes are not caused by allergies, then it is very likely that the patient suffers from an eye disease such as dacryocystitis. Although the incidence of dacryocystitis is not too high, its impact on patients cannot be underestimated. Next, I will introduce the causes, clinical manifestations and treatments of dacryocystitis.

1. Causes of the disease

The exact cause has not yet been determined. Dacryocystitis is often secondary to inflammation of adjacent tissues, such as the conjunctiva, nasal cavity and paranasal sinuses, or some special infections such as tuberculosis or syphilis. For those that originate in the lacrimal duct system, the cause is unclear.

2. Clinical manifestations

1. Acute dacryocystitis

Generally, the skin in the lacrimal sac area at the root of the nose will appear red, swollen, hot, and painful, and even the face on the same side will swell, sometimes accompanied by enlargement and tenderness of the preauricular and submandibular lymph nodes, tears in the eyes, and purulent secretions from the lacrimal puncta. When the abscess is localized, it can break through the skin surface. Most patients usually have a history of chronic dacryocystitis.

2. Chronic dacryocystitis

It is often manifested as tearing and excessive eye secretions. When squeezing the affected lacrimal sac area, a large amount of purulent or serous secretions can be seen gushing out from the lacrimal puncta, and the affected tear duct cannot be flushed smoothly.

3. Treatment Methods

1. Medication

Use various antibiotic eye drops topically, 3 to 4 times a day. Squeeze and empty the lacrimal sac secretions before dropping the medicine so that the medicine can be absorbed into the lacrimal sac. Use sulfonamides or antibiotics systemically to eliminate purulent secretions, but cannot relieve blockage and retention as a preparation before surgery.

2. Flushing the tear duct

In order to completely remove purulent or mucous secretions, the lacrimal sac can be flushed with normal saline, and then 0.3 to 0.5 ml of antibiotics can be injected. Flushing with a mixture of antibiotics, corticosteroids and cellulose-soluble fluid can have a better effect on early blockages without fixed scars.

3. Lacrimal duct intubation

For patients whose obstruction is in the nasolacrimal duct, tear duct intubation surgery can be considered. First, the tear duct is explored, then the tear duct is dilated and the tear duct is inserted.

4. Dacryocystorhinostomy

The local nasal mucosa and lacrimal sac are surgically anastomosed together to create a channel for draining tears.

5. Lacrimal cystectomy

The indication should be selected according to the situation: patients with atrophic rhinitis, lupus, tuberculosis, syphilis, inflammation of the tissues around the lacrimal sac or purulent inflammation of the ethmoid sinus, malignant tumors, corneal inflammation, endophthalmitis, ocular trauma, etc. should first consider lacrimal sac removal.
