SURGICAL TREATMENT OF OPEN-ANGLE GLAUCOMA

The influence of intraocular pressure (IOP) on the visual field of glaucoma patients is discussed; the criterion level for postoperative IOP control was set at 20 mmHg. When the IOP exceeded this level for two consecutive months, the IOP control was judged to be a failure, and the surgical results were analysed by a life-table method.
Argon laser trabeculoplasty (AL T) with 50 shots over 180° of the angle was used routinely, because of fewer complications than with 360° ALT. A second session sometimes improved the final success rate, which was about 57% in primary open-angle glaucoma and 94% in capsular glaucoma after a follow-up period of two years and two months. All patients (120 eyes) required drugs, but their use could be reduced in about 35%. The IOP distribution in successful cases showed a peak at 16 to 17 mmHg, and the IOP was 15 mmHg or less in 21%.
In trabeculectomy, pretreatment with topical indomethacin and steroid drip infusion was advocated, and concentrated sodium hyaluronate was used during surgery. These procedures reduced the incidence of shallow anterior chamber and associated choroidal detachment. The final success rate was about 60% after five years of follow-up. The IOP distribution after more than two years peaked at 13 to 15 mmHg, and the IOP was 15 mmHg or less in 53%.     

SURGICAL TREATMENT OF EXFOLIATIVE GLAUCOMA

Exfoliation syndrome (XFS) is a common cause of secondary open-angle glaucoma in many populations. Signs of XFS may be seen in over twenty percent of patients in Iceland and Finland. As we found in Armenian population about forty percent of all patients with different types of glaucoma have XFS. We have     

EXPERIMENTAL BASIS OF NONABSORBED COLLAGEN IMPLANT APPLICATION IN SURGICAL TREATMENT OF GLAUCOMA

The experimental research of firm porous implant from pure collagen for non-penetrating deep sclerectomy showed that fluid flow could be through all volume of material. The implant is biologically inert and the pathologic influence on sclera is minimum. The hystological results showed that for three months the implant has stayed to free from fibrosis formation and its     

COMPARATIVE ESTIMATION OF PRIMARY OPEN－ANGLE GLAUCOMA SURGICAL AND MEDICINES TREATMENT MINIMAL COST

Dispensary list retrospective analysis was carried out. Analysis and comparison of direct and indirect expenses of two hundred seventeen patients were made for period two years. Total amount of all expenses for dispensary patient varied from USD two hundred fourteen to three hundred ninety eight per year. The above

INNOVATIVE SURGICAL MANAGEMENT OF NEOVASCULAR GLAUCOMA

A brief introduction on the essentials of etiology/pathophysiology of neovascular glaucoma precedes a review on the surgical op- tions to treat this low prognosis form of secondary glaucoma including the pros and cons of each procedure.

SIMULTANEOUS SURGICAL MANAGEMENT OF CATARACT AND GLAUCOMA

This paper reports and analyses 70 combined cataract and trabeculectomy operations carried out on 50 patients by the two authors from 1973 to mid 1979.
Control of glaucoma was achieved by surgery alone in 86%, the remaining 14% required additional medical therapy to achieve control. This therapy was less than that used preoperatively. Where the preoperative control was good 96% achieved post operative control without therapy. In eyes with poor preoperative control, 80% achieved post operative control without therapy.
The complication rate was low and no eyes were lost in the series.
The literature for alternatives for managing cataracts and glaucoma has been reviewed and analysis of this shows the following percentage control by surgery without additional medical therapy. (a) Cataract extraction alone 40.5%. (b) Drainage procedure followed by lens extraction 65.5%. (c) Combined cataract and glaucoma surgery other than trabeculectomy 79%. (d) Combined cataract and trabeculectomy 91%.
The latter combined procedure is recommended for all eyes with coexistent cataract and glaucoma.
