Erythroptosis
Introduction
Introduction to the sag The sag of the red film is also known as the "hanging barrier", which is similar to the trachoma of the cornea. This disease is mostly caused by the treatment of pepper sores (sand eyes) or treatment, and then add heart, lung, liver, wind and heat, internal fire, resulting in blood stasis. The main symptom is that the entire row of small blood vessels invades the black eyes from the top of the white eye. The patient often has itchy eyes and is ashamed. Severe and fearful to the pupil, the diaphragm is thin. basic knowledge The proportion of sickness: 0.01% - 0.03% Susceptible people: no specific people Mode of infection: non-infectious Complications: scleritis
Cause
Cause of sag
Cause:
This disease is mostly caused by the treatment of pepper sores (sand eyes) or treatment, and then add heart, lung, liver, wind and heat, internal fire, resulting in blood stasis.
Prevention
Prevention of sag
Any contact with this secretion can cause an opportunity for trachoma to spread infection. Therefore, it is necessary to strengthen publicity and education, pass on the knowledge of preventing and treating eye diseases to the masses, and implement the principle of prevention. Develop good hygiene practices. Do not rub your hands, towels, handkerchiefs should be washed and dried; nurseries, schools, factories and other collective units should be divided into basins or running water to wash the face, the treatment of trachoma patients should be actively treated, strengthen the hairdressing room, bathroom, hotel and other service industries Hygiene management, strict disinfection system such as towels and washbasins, and pay attention to clean water.
Complication
Obliteral ptosis complications Complications scleritis
The incidence of binocular disease in both eyes can not be timely, and it can develop into bloody eyes.
Symptom
Signs of ptosis, common symptoms, tears, itchy eyes, dry eyes, monocular eyes, black eyes, photophobia, eye pain, visual impairment, eye abnormalities
1. More common in pepper sores, severe sore.
2. The red veins extend from top to bottom to the black eye, and have a thin film to cover the black eyes, forming a clear boundary with normal black eyes. The fluorescein staining is needle-like staining or seeing into a half-moon shape.
3. The inner surface of the sputum is covered with pepper sores.
4. Consciously in the eye, sand pain, fear of light and tears, visual impairment.
Examine
Oval drooping examination
Pathogenic detection
(1) Smear detection of chlamydial inclusion bodies: In recent years, Papanicolaon staining has been reported to detect Chlamydia trachomatis inclusion bodies with a sensitivity of 83%. The method is simple and is the most commonly used screening method, which can be used for screening high-risk groups.
(2) Cell culture method: It is considered to be the gold standard for detecting Chlamydia trachomatis, but it is time consuming and requires certain equipment technical conditions, which is difficult to be used as a routine clinical detection method.
2. Molecular biological methods in situ hybridization to detect Chlamydia trachomatis DNA in cervical or rectal biopsy specimens. It can also be detected by PCR, which can significantly improve the detection sensitivity, and can be used to identify its species and serotype. It can be used for diagnosis, efficacy judgment and epidemiological investigation. The detection rate of this method is higher than other methods. Hot start PCR (HSPCR) has also been reported to significantly reduce non-specific amplification and reduce false positive reactions.
The PCR method can be used for the diagnosis of this disease, and can also be used for the evaluation of the therapeutic effect after treatment, but it should be noted that when the efficacy is followed up after stopping the drug, some of the antigens detected by direct immunofluorescence are negative, but the PCR method is still positive. It may be that part of the pathogenic DNA is in the body and does not indicate the presence of pathogens.
Diagnosis
Diarrhea diagnosis
In the eyes of the moon: the whitish on the upper side of the wind wheel, the shape of the crescent, gradually eroding downward as the main performance, no red vein drooping, fluorescein staining without coloring, usually no symptoms.
