An iridectomy is an eye surgery that involves removing part of the iris.
The iris is a ring-shaped structure at the front of the eye that surrounds the pupil and regulates the amount of light entering the eye. It consists of pigment cells and smooth muscles.
Iridectomy can be performed for several reasons:
-
Treatment of glaucoma - increased intraocular pressure. Removing part of the iris improves the outflow of intraocular fluid and reduces pressure.
-
Elimination of iris defect.
-
Removal of iris tumors.
-
Treatment of secondary cataracts - clouding of the lens after cataract surgery.
The operation can be performed in two main ways:
-
Anterior iridectomy - an incision is made on the front side of the iris.
-
Posterior iridectomy - an incision is made from the posterior chamber of the eye.
Iridectomy is usually performed under local anesthesia. The iris incision can be either straight or wedge-shaped. After the iris fragment is removed, the edges of the incision may be closed with sutures or left to heal.
The operation helps normalize the outflow of intraocular fluid and reduce intraocular pressure. Iridectomy is an effective treatment for certain eye diseases.
Iridectomy (from the Greek iris - iris and ektome - cut out) is the removal of a certain part or the entire edge of the iris during surgery. As a result, the innervation of the iris is disrupted and the configuration of its angle changes. The procedure improves the patient's visual acuity.
During iridectomy, the melanocytic pigment in the peripheral part of the iris is removed, which helps to relax the Müller muscle, which is responsible for the contraction of all retinal vessels. This improves blood circulation in the last neural structures supplying blood to the retina and dilates blood vessels. As a result, the image passing through the eye becomes clearer, and the objects themselves become distinguishable.
Removal of part of the iris is performed due to pathology associated with the visual organ. The main indication for the use of iridectoma is iridocyclitis in the relapse stage - a chronic inflammatory reaction involving the pupil and iris.
**Hypertension and pseudohypertension.** The pressure in the eyeball increases quite strongly from the manifestation of the disease, expressed in increased eye pressure. Therefore, such a pathology, contrary to popular belief, does not always indicate heart disease and requires little intervention in the patient’s eyes and ophthalmology. The cause of the development of iridocyclitis is a violation of the integrity of red blood cells due to mechanical trauma or other damage to blood vessels. Sometimes the cause is an infection that causes fibrin to leak into the vascular walls. A small amount of hyaline, a special protein substance, is formed in the eye. If you do not get rid of compactions and fibrosis of the iris layer, they begin to fill the eyeball, leading to
Iridectomy is called eyeball surgery. It is indicated for poor vision and severe pathologies associated with abnormal development of the eye. During surgery, the front portion of the iris (iris) is removed. During it, the operating specialist makes a small incision in the eye through the inner membrane. Next, using a surgical instrument, the doctor removes the affected area of the iris. After this, a silicone implant is fixed in the wound. Upon completion of the operation, the doctor applies a bandage to the eye area and makes all the necessary recommendations regarding postoperative eye care.
