Operation Fistulizing

Operation Fistulizing: Striving to reduce intraocular pressure in glaucoma

Glaucoma is a chronic eye disease characterized by increased intraocular pressure, which can lead to damage to the optic nerve and loss of vision. Treatment of glaucoma is aimed at reducing intraocular pressure to prevent progression of the disease. One of the effective surgical procedures used for glaucoma is the fistulizing operation.

Fistulizing surgery, also known as fistulizing glucomafistulation, is a surgical procedure aimed at creating a permanent drainage of aqueous humor from the anterior chamber of the eye. This is achieved by creating a filter scar in the scleral part of the corneal limbus.

During fistulization surgery, the surgeon makes a small hole in the sclera (the white lining of the eye) near the peripheral part of the cornea. A filter scar is then created that allows aqueous humor to flow freely from the anterior chamber of the eye. This reduces intraocular pressure and prevents damage to the optic nerve.

Operation Fistulizing has several advantages. First, it provides a lasting reduction in intraocular pressure, which may be especially useful for patients with high pressure levels who do not respond to conservative treatment. Secondly, the procedure is relatively simple and can be performed on an outpatient basis. In addition, Fistulizing surgery can be effective both as a primary treatment for glaucoma and in cases where other treatment methods have been ineffective.

The Fistulizing operation may have some limitations and complications. Some patients may develop infection, bleeding, or swelling after surgery. In addition, ocular hypotension (increased aqueous outflow) may develop, which can lead to a decrease in intraocular pressure below normal levels. Therefore, it is important to carefully evaluate patients and conduct detailed consultation before undergoing surgery.

In conclusion, fistulization surgery is a surgical procedure that can be an effective treatment for glaucoma. Creation of a filter scar in the scleral part of the corneal limbus ensures a constant outflow of aqueous humor from the anterior chamber of the eye and reduces intraocular pressure. Despite its limitations and possible complications, fistulizing surgery can be an effective treatment option for patients with glaucoma, especially those who have failed other treatments. It is important to consult an experienced ophthalmologist who will conduct a detailed examination and explain the possible risks and benefits of the operation.

**Fistulizing operation (FR) for glaucoma** Patient’s name: Ivan Ivanovich Ivanov Date of birth (dd.mm.yyyy): 01/01/1970 Gender: male

She was admitted to (DGTU)* with a diagnosis: **Primary GLAUCOMA**. PMU C, optic neuropathy grade 2, ouu-4, PITR (longevity index). IOP (q, t) – 26, 36 mm Hg. At the time of admission, the condition was serious. Symptoms of intoxication, severe weakness, nausea, dizziness. The fundus is dilated, the optic disc is swollen to I/3, the vessels are narrowed and full of blood, the excavation of the pupil is not determined. In the central field of view up to 20°. The patient was treated in a hospital setting, including infusion therapy and symptomatic therapy. On October 21, 16, the operation Fistulization for glaucoma was performed. **The operation was performed under local anesthesia.** Diagnosis at discharge: **Combined initial glaucoma,** N **2**, **PMU B** (last level). The operation was performed to reduce IOP with subsequent fixation of the achieved IOP through periodic examination of patients. **Operation:** The patient underwent inversion of the iris flap and fixation with a suture
