Abstract

During a ten-year period, we treated 241 eyes by transscleral ruby laser cyclocoagulation. Each eye had a minimum follow-up of six months. The average was 24 months and the range was six to 92 months. Using a criterion for success of intraocular pressure between 5 and 22 mm Hg, we achieved an overall success rate of 62% (150 of 241 eyes). This success rate varied from 86% for aphakic open-angle glaucoma (32 of 37 eyes) to 53% for neovascular glaucoma (72 of 135 eyes). Most eyes with useful vision preoperatively maintained these levels. Chronic hypotony (41 eyes) and phthisis (17 eyes) were the most frequent complications, although phthisis was common only in the neovascular glaucoma group (13 eyes). The visual results are more favorable and the need for retreatment and postoperative medications is less than with cyclocryotherapy, and postoperative discomfort is considerably reduced.

Do scleral flap dimensions influence reliability of intraocular pressure control in experimental trabeculectomy?

AIM: To compare the effect on intraocular pressure (IOP) of large vs small scleral flap size during trabeculectomy using adjustable sutures. METHODS: Trabeculectomy operations were performed on nine donor human eyes connected to a constant flow infusion with real-time IOP monitoring. Large scleral flaps (4 x 4 mm, 16 mm(2), n=12) or small scleral flaps (3 x 2 mm, 6 mm(2), n=9) were constructed over 0.76 mm(2) sclerostomies. For each procedure, equilibrium IOP was measured following tight closure with two four-throw adjustable 10-0 nylon sutures. RESULTS: Five scleral flaps were thin or poorly constructed; four of these were in the initial seven procedures, implying learning effect. These had a mean absolute IOP of 7.6 mmHg (range 2.7-12.4 mmHg) and mean relative IOP of 28.3% of baseline (range 10-45.8%) after closure. In the remaining 16 good quality procedures, mean IOP was 1.3 mmHg (range 0-3.4 mmHg) after sclerostomy, confirming minimal outflow resistance before closure. Following flap closure mean IOP was 20 mmHg (SD 4.4, range 15.5-29.3 mmHg) for large (n=8), and 18.7 mmHg (SD 3.6, 15.9-25.8 mmHg) for small (n=8) flaps (unpaired t-test, P=0.26). Mean IOP (% baseline) was 71.6% (SD 8.4, range 60.6-86.6%) and 66% (SD=12.7, 46.8-86.6%) for large and small flap groups, respectively (unpaired t-test, P=0.2). CONCLUSIONS: Well-constructed scleral flaps of both sizes were able to support an average IOP at least two-thirds of baseline, and both had similar absolute IOP levels. Errors in flap construction resulted in loss of IOP control. Smaller flap size does not appear to compromise control of early postoperative IOP using adjustable sutures.
