Purpose: This study compares the outcomes of trabeculectomy and Molten
o implantation in the treatment of glaucomas associated with uveitis.
Methods: Forty-five patients with uveitis, who had undergone filtering
surgery for glaucomas associated with uveitis, were reviewed retrospe
ctively. Successful outcome was defined as final intraocular pressure
(IOP) of 6 to 21 mmHg, with a minimum follow-up of 6 months without vi
sually devastating complications or loss of light perception. Results:
One- and two-year life-table success rates, respectively, were 81% an
d 73% with trabeculectomy (16 patients); 53% and 31% with combined tra
beculectomy and first-stage (reserve) Molteno implantation (19 patient
s); and 79% and 79% with one-stage Molteno implantation (10 patients).
In 11 patients who underwent second-stage Molteno implantation after
trabeculectomy failure, 1- and 2-year life-table success rates were 79
% and 79%, respectively. Complications included surgically treated cho
roidal effusions (1/45; 2%), choroidal hemorrhages (3/45; 7%), and chr
onic hypotony (3/45; 7%). Follow-up in all groups ranged from 5 to 70
months (mean +/- standard deviation, 28 +/- 17 months). Conclusions: T
rabeculectomy provides surprisingly good results in glaucomas associat
ed with uveitis (modulation of wound healing with antimetabolites prob
ably would afford an even higher success rate). However, when signific
ant, immediate postoperative and/or moderate chronic postoperative inf
lammation is likely, aqueous drainage devices appear more likely to co
ntrol IOP.
