Iridectomy Subconjunctival External

Iridectomy (removal of the iris) is a surgical operation that is performed to treat various eye diseases, such as glaucoma, uveitis, cataracts, etc. One type of iridectomy is subconjunctival external iridectomy.

Iridectomy ab externo is performed under local anesthesia and lasts about 15-20 minutes. It involves removing part of the iris through a small incision in the conjunctiva. This method is used for a variety of eye diseases, including glaucoma and uveitis.

Subconjunctival iridectomy is a more gentle method compared to other types of iridectomies, since it does not require the removal of a large amount of iris tissue. However, it can also be used for more severe conditions such as cataracts.

After an ab externo iridectomy, the patient may experience discomfort and pain for several days. However, these symptoms usually go away within a few days.

Thus, ab ekterno iridectomy is an effective treatment for various eye diseases, including glaucoma, uveitis and cataracts. It is performed under local anesthesia and does not require long recovery after surgery.

Iridectomy (through an incision in the eyelid), or external irideothoracotomy, is the operation of removing the iris for glaucoma without dissecting the sclera (most often under local anesthesia, sometimes under general anesthesia, in case of toxicosis of pregnant women, in a very weakened state).

I.s. are called ways of moving the ciliary body beyond the posterior chamber by performing an additional paracentesis of the sclera under the cornea outside the anterior chamber of the eye in the corner between the dentate line of the sclera and the ciliary body. With the help of I. S., proposed by O. Förster, it is possible to isolate the ciliary body, iris and lens without direct damage to the sclera. Sometimes, after the initial cut of the sclera behind the dentate line, a special raspatory knife is inserted through a paracentesis to separate the ciliary muscle, which penetrates well between the posterior surface of the ciliary muscles and their appendages and does not injure the sclera, after which the iris is easily pulled up along the axis of the optic nerve and separated at the end knife from the posterior surface of the ciliary-capsular loop. To avoid bleeding of the severed iris and the formation of pulsating bleeding, it is first lubricated with a hemostatic solution. Then the posterior surface of the ciliary muscle is sequentially removed and the lens is unscrewed, or a paralyzing blockade is performed to facilitate its isolation. Subconjunctival surgery is called. An incision is made in the conjunctiva, i.e., the soft membrane on the eyeball, in order to open the capsule of the transparent cornea located underneath. After an external incision of the conjunctiva up to the free edge of the cornea between the
