Introduction
Introduction to tears Anyone who has excessive tear secretion due to inflammation of the eye, foreign body stimulation, emotional impulses, etc. is called tears. Anyone with dysfunction in any part of the lacrimal duct causes tears to overflow. Long-term tears, redness, roughness, and eczema near the internal hemorrhoids, as the patient continues to swab down, can promote valgus valgus. The treatment of this disease is mainly to correct the valgus valgus, to restore the normal position of the tears, and to treat blepharitis. Tear small point stenosis or occlusion of the tears small expansion, puncture incision or bite cut. If the lacrimal canal or the main tube is obstructed, the light can be forcibly intubated by the probe. Severe cases can be used for conjunctival lacrimal sac anastomosis or intubation. Or by their own vein bridge to communicate the lacrimal sac and conjunctiva. basic knowledge The proportion of illness: 0.003--0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: vitreous opacity
Cause
Cause of overflowing tears
(1) Abnormal tears: tears can not flow into the lacrimal passage when the tears are everted, narrow, occluded or have no tears.
(B) abnormal lacrimal duct: dysplasia (congenital atresia), trauma, foreign body, inflammation, tumor, scar contraction or nasal disease, etc., narrowing or obstructing the lacrimal duct, can cause tears.
Prevention
Diabetes prevention
Usually pay more attention to keep your eyes clean and not rub your eyes with dirty hands or dirty handkerchiefs.
Complication
Hemorrhagic complications Complications vitreous opacity
Most of the complications occurred after eye surgery, such as dilated pupils and vitreous opacity.
Symptom
Symptoms of overflowing tears common symptoms eversion eczema
Long-term tears, skin flushing near the sputum, rough, eczema, as the patient continues to wipe down, can promote valgus valgus.
Examine
Examination of tears
(1) Fluorescein test
(two) lacrimal irrigation
Analysis of lacrimal irrigation results:
1. There is no resistance when the normal person injects the rinsing liquid, and the rinsing liquid flows smoothly into the nasal cavity or the pharynx.
2. There is resistance when injecting the rinsing liquid, part of it returns from the small point of the tear, and part of it flows into the nasal cavity, which is the narrowing of the nasolacrimal duct.
3, the flushing fluid completely from the original path of the injection is blocked by the lacrimal canal.
4, the flushing fluid is injected from the small tears, and returns from the small tears, which is blocked by the total tear duct.
5, the rinsing liquid returns from the small tears at the same time, there is mucus or mucus purulent secretion flow out, for the nasolacrimal duct obstruction, combined with chronic dacryocystitis.
(3) X-ray iodine angiography can be performed if necessary. The contrast agent can be injected through the lacrimal canal with a lacrimal sac flushing needle. Immediately take a picture of the anterior and posterior position and the lateral position to understand the size of the obstruction of the lacrimal passage and the size of the lacrimal sac.
Diagnosis
Diagnosis and diagnosis of tears
diagnosis
Diagnosis can be made based on medical history, clinical manifestations, and examination.
Differential diagnosis
Identification with dacryocystitis, chronic lacrimal gland inflammation, acute lacrimal gland inflammation, excessive secretion of tears.
