[A method for forming a conjunctival flap in trabeculectomy].

The paper describes results after trabeculectomy using 4 variants of conjunctival flap formation. The influence of the method of conjunctival flap formation on the formation of the filtration cushion as well as a hypotensive effect of the operation are analysed. The method was used in 80 patients (83 eyes) with primary open-angle glaucoma. It was found that a traditional method of conjunctival flap formation (with the basis to the limbus), as compared with the non-traditional ones (with the basis to the fornix and a radial one), creates better conditions for the formation of the optimal filtration cushion and provides a stable hypotensive effect of trabeculectomy (87.5%).

[The filtration "pseudopad"].

Among 10 patients with primary open-angle glaucoma with a filtration "pseudo-cushion" that prevented compensation of intraocular pressure after trabeculectomy, normalization of intraocular pressure by means of medicamentous treatment (thymolol) could be achieved in 1 patient; in the rest of the patients surgical intervention was required. It is stated that the most effective is early surgical intervention: dissection of the Tenon's capsule "cyst" and resection of the episclera in the zone of the primary surgery.

[The influence of the fixation of the scleral flap on the hypotensive effect of trabeculectomy].

The author analyzes 60 trabeculectomies with fixation of the superficial scleral flap by three nodular sutures (n = 24) and by one nodular suture (n = 36). He comes to the conclusion that trabeculectomy with scleral flap fixation by one nodular suture is preferable to its fixation with three sutures, for it creates better conditions for the formation of filtration pad and provides a more stable hypotensive effect, as evidenced by the results of three-year follow-up (75% vs. 41.6%). Nonetheless the author claims that fixation of the scleral flap with 3-4 sutures is desirable in cases when filtering trabeculectomy variants are deliberately employed or when trabeculectomy modifications with uveoscleral discharge stimulation are used.

[Technique and results of modified trabeculectomy].

The author suggests double trabeculectomy with episclera resection and anguloplasty to be performed in cases with uncompensated open-angle glaucoma. Each of the elements of such surgery is aimed at slowing down the reparative processes in various sections of the fistulous route and therefore this route can function longer. Forty-six patients (50 eyes) with primary open-angle glaucoma were operated on. Normalization of the ophthalmic tone immediately after surgery was achieved in 100% of cases. The results of surgery were followed up in 30 patients (32 eyes) for 6 months to 2 years. Stable normalization of intraocular pressure was achieved in 97% of cases, vision acuity in 81%, and visual field in 91% of those operated on. Good stable hypotensive effect of such surgery recommends it most of all for patients at a high risk of excessive cicatrization (young patients, repeated surgery, etc.).

[Modification of sinusotomy].

Sinusotomy modification, developed by the authors, consists in combination of traditional subscleral surgery with posterior cyclo-retraction and the formation of an uveal pouch. This technique was used in the treatment of 28 patients (28 eyes) with primary open-angle glaucoma. Immediate hypotensive effect was achieved in all the patients (in one case surgery was paralleled by pilocarpine instillations). Twenty-four patients were examined in late periods (up to 1 year) after surgery. Ophthalmic tone normalization was achieved in 91.7% of cases (in 83.3% of cases no drug instillations were used). Vision acuity and visual field were unchanged or improved in 87.5 and 95.8% of cases, respectively. No grave complications were recorded.

[Technique of suprachoroidal space drainage in the prevention and treatment of ciliary-choroidal detachment after glaucoma surgery].

The authors recommend cross-like sclerotomy to prevent and treat a ciliary-choroidal detachment after antiglaucoma surgery. Double cross-like sclerotomy was performed in the upper half of the eye simultaneously with trabeculectomy in 30 patients with open-angle glaucoma to prevent the development of ciliary-choroidal detachment. Thirty patients subjected to similar surgery but without prophylactic sclerotomy have made up the reference group. The results evidence that double cross-like sclerotomy is an effective method for the prevention of ciliary-choroidal detachment: the incidence of this complication has dropped by 8 times (from 26.7 to 3.3%). Gross-like sclerotomy performed to treat utricular ciliary-choroidal detachment resulted in cure in all the 14 cases. The suggested sclerotomy technique is simple and low-traumatic.

[Effect of ciliary choroid detachment on the late results of trabeculectomy ].

The relationship between ciliochoroidal detachment on the late hypotensive results of trabeculectomy was studied in 64 patients with primary open-angle glaucoma. Seventy patients, matched for their initial condition and age, in whom the postoperative period ran without complications, made up the reference group. The mean follow-up period was 24.2 months. Ciliochoroidal detachment was found to have virtually no effect on the late hypotensive results of trabeculectomy, though such detachment had a negative effect on the lens transparency.

[The effect of anti-glaucoma surgery on the visual function in patients with primary glaucoma].

Examinations of the visual field in 25 patients with Stages I and II primary open-angle glaucoma have shown that in the majority of cases surgery results in improvement of stabilization of the visual field status in respect of all its parameters (retinal sensitivity threshold, deficiency of the field and sensitivity). Increase of the number of defects and reduction of the retinal ability to discern light were observed in 5 patients: in 2 with postoperative hypotension and 3 with progressive cataracts.

[Practical value of preventive posterior sclerectomy in trabeculectomy].

The results of prophylactic posterior sclerectomy, carried out to prevent ciliochoroid detachment in antiglaucoma fistulization surgery (trabeculectomy in various modifications) are analyzed. A total of 293 patients (303 eyes) were under study. In 51.8 percent of cases (157 eyes) trabeculectomy was combined with prophylactic sclerectomy, carried out both in the upper (121 eyes) and lower (36 eyes) segments of the eye. The results evidence that prophylactic posterior sclerectomy promoted a 2.3 times reduction (from 28.1 to 12.1 percent) in the incidence of ciliochoroid detachments; the site of this operation (upper of lower segment of the eye) was of no essential importance. The authors recommend prophylactic posterior sclerectomy as an effective method for prevention of ciliochoroid detachment.

[Fistulizing reoperations in open-angle glaucoma].

The authors analyze the results of repeated fistulization surgery (traditional trabeculectomy and that combined with resection of the episclera, and valvular trabeculectomy) in 40 patients (41 eyes) with primary open-angle glaucoma. A follow-up of 6 mos to 4 yrs has shown normalization of the ophthalmic tone in 90.2% of cases, in 65.8% of these this was achieved without drugs. Vision acuity remained unchanged or improved in 58.5% of cases, visual field was preserved or improved in 80.5% of patients. These results have lead the authors to a conclusion that a stable hypotensive effect can be achieved if repeated fistulization is performed outside the site of the primary intervention. If repeated trabeculectomy has to be performed at the site of the primary intervention, it is recommended to be combined with resection of the episclera, this improving the reliability of the hypotensive effect of surgery.

[The effect of the method for forming the conjunctival flap in glaucoma fistulizing operations on the development of a stable acquired ptosis of the upper eyelid].

The relationship between the incidence rate and severity of acquired ptosis and the technique of the conjunctival flap formation in trabeculectomy were under study. A total of 117 patients were followed up. In 70 the flap was formed by the traditional method, with the foot to the limbus, and in 47 by the nontraditional technique, with the foot to the vault and radially. Stubborn (a follow-up of more than 6 mos postoperation) acquired ptosis of the upper eyelid was observed in 38.5% of patients; it was more often after the traditional technique of the conjunctival flap formation (48.6%) and rare and approximately to the same extent when nontraditional methods were used (23.4%). The incidence rate and severity of ptosis increase as the height of the incision on the conjunctiva (from the limbus), made by the traditional technique of the flap formation, grows. A more frequent development of ptosis after traditional formation of the conjunctival flap vs. the nontraditional techniques may be explained by injuries to the individual branches of the oculomotor nerve, participating in the innervation of the posterior peduncle of the levator muscle of the upper eyelid.
