Introduction
Introduction to scarring varus The varus is an abnormal state in which the cornea is wound, and part and all of the eyelashes are inverted to the eyeball to stimulate the cornea. Both the upper and lower jaws can occur. It is caused by scarring of the conjunctiva and tarsal plate. Trachoma is common. In addition, conjunctival burns, conjunctival and herpes can also occur after the disease. basic knowledge Sickness ratio: 0.0001% Susceptible people: no specific people Mode of infection: non-infectious Complications: corneal ulcer
Cause
The cause of scarring varus
Scar varus: caused by scarring and constriction of the conjunctiva and tarsal plate, common in the scarring period of the trachoma, can also occur after conjunctival burns, conjunctival pemphigus and diphtheria conjunctivitis.
Prevention
Scar prevention
Pay attention to eye hygiene and find that the eyes are uncomfortable and timely treated.
Complication
Scar varus complications Complications corneal ulcer
Conjunctival congestion, corneal ulceration, and decreased vision.
Symptom
Scarring palpitations, common symptoms, photophobia and tears, eyelids, tingling, corneal ulcer, visual impairment, varus
The patient has symptoms such as photophobia, tearing, tingling, and eyelids. Check that the seesaw, especially the rim portion, curls in the direction of the eyeball. Trichiasis rubs the cornea, the corneal epithelium can fall off, and the fluorescein diffusely stains. Such as secondary infection, can develop into corneal ulcers. If it does not heal for a long time, the cornea has new blood vessels and loses transparency, causing vision loss.
Examine
Examination of scarring varus
Check: The sacral margin is different from the normal position, and it is obviously curled in the direction of the eyeball. The eyelashes then fall back to the ball, stimulating the cornea and the bulbar conjunctiva.
Diagnosis
Diagnosis of scar stenosis
Due to long-term stimulation, severe cases develop into corneal ulcers, and corneal fistulas are formed later, resulting in varying degrees of visual impairment and even blindness.
It is easy to make a diagnosis based on the patient's age, presence or absence of trachoma, and clinical manifestations.
