iris cyst
Introduction
Introduction to iris cyst The iris cyst is caused by the penetrating injury of the eyeball or the operation of the inner eye. The conjunctiva or corneal epithelium enters the anterior chamber through the wound, and is implanted in the iris and continuously proliferated. There are many causes of iris cysts, including congenital, traumatic implantability, inflammatory exudation and parasitic. Among them, traumatic implants are the most common. The iris cyst can be extended to the posterior chamber, and there is a black bulge after seeing the iris in the pupil area. The disease should be treated early, and the cyst should be removed together with the affected iris tissue during surgery. The corneoscleral incision should not be too small during surgery to fully expose the cyst, completely eliminating and reducing the risk of damage to the lens. If the cyst is large and the extent of involvement is wide, local surgical resection combined with laser therapy or radiation therapy may be considered. In order to remove or inhibit the residual wall tissue, to avoid recurrence. basic knowledge The proportion of illness: 0.02% Susceptible people: no specific population Mode of infection: non-infectious Complications: glaucoma
Cause
Iris cyst etiology
There are many causes of iris cysts, including congenital, traumatic implantability, inflammatory exudation and parasitic. Among them, traumatic implants are the most common. It is due to eyeball penetrating injury or internal eye surgery, the conjunctiva or corneal epithelium enters the anterior chamber through the wound, implanted in the iris and continuously proliferated.
Prevention
Iris cyst prevention
The disease should be treated early, and the cyst should be removed together with the affected iris tissue during surgery. The corneoscleral incision should not be too small during surgery to fully expose the cyst, completely eliminating and reducing the risk of damage to the lens.
Complication
Iris cyst complications Complications glaucoma
When the cyst enlarges the anterior chamber or blocks the angle of the anterior chamber, it can cause uncontrollable glaucoma.
Symptom
Iris cyst symptoms Common symptoms Iris iris iridescent iris blue
The iris cyst can be extended to the posterior chamber, and there is a black bulge after seeing the iris in the pupil area.
Examine
Iris cyst examination
Eye examination. Anterior chamber keratoscopy, iris examination, ultrasound examination of eyeballs and eyelids, eye function examination, etc.
Diagnosis
Diagnosis and identification of iris cyst
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
The iris cyst can be extended to the posterior chamber. After the iris is seen in the pupil area, there is a black bulge, which is easily misdiagnosed as melanoma.
