[The laser correction of recurrent elevated intraocular pressure after a surgical operation to control glaucoma complicated by the blocking of the postoperative fistula by the root of the iris]. / Lazernaia korrektsiia retsidiva povysheniia vnurtriglaznogo davleniia posle antiglaukomatoznoi khirurgicheskoi operatsii, oslozhnennoi blokadoi posleoperatsionnoi fistuly kornem raduzhki.

Laser intervention was carried out in 18 patients (18 eyes) with open-angle glaucoma and decompensated intraocular pressure, that developed in 2 weeks--5 years after primary antiglaucoma surgery. Developed glaucoma stage was diagnosed in 16 eyes, in 2 eyes far-advanced condition was found. Blocking of the fistula by the iridal root was responsible for the inefficacy of fistulizing surgery. Laser trabeculoplasty to compensate for the intraocular pressure was carried out in 18 eyes, in 9 eyes this treatment was combined with gonioplasty. Stable normalization of intraocular pressure was observed in 13 eyes in remote periods after laser coagulation. Analysis of the results has brought the authors to a conclusion that the administered laser trabeculoplasty as an individual treatment modality and in combination with gonioplasty is fairly effective, results in prolonged compensation of the ophthalmic tone, and is altogether less traumatic than repeated surgery.

Wise's laser trabeculoplasty with a 270 degrees exposure was used in 22 eyes of 22 patients with operated-on decompensated glaucoma. Patients with elevated decompensated intraocular pressure after sinusotrabeculoctomy were included in this group. The postoperative fistula was located in front of the Schlemm's canal in them. A dynamic follow-up has shown a stable normalization of the ophthalmic tone in 62% of cases without maintenance therapy. As a repeated intervention, laser trabeculoplasty is less traumatic, yields a good therapeutic effect, and may be widely used as a method to correct elevated intraocular pressure after earlier sinusotrabeculectomy.
