| Summary: |
Purpose: The
evaluation of intraocular pressure and number of
complications in the early postoperative period in
patients after trabeculectomy with viscoelastic agent
used to recreate the anterior chamber at the end of
procedure.
Material and methods: Between November 2001 and
February 2002, in 56 patients (58 eyes) with primary
open-angle glaucoma trabeculectomy was performed.
Patients were divided into two groups. Trabeculectomy
was performed with leaving the viscoelastic agent (Provisc)
in the anterior chamber at the end of surgery in 29 eyes
of 28 patients (Group A), while in 28 patients (29 eyes)
the anterior chamber was filled with Ringer solution (Group
B). Preoperative IOP in group A ranged from 19 to 48
mmHg, mean – 28,41 mmHg. In group B it ranged between 19
and 41 mmHg, mean – 25,07 mmHg. The follow-up time was 1
month in every case.
Results: The mean IOP on the first, fifth, 14th
and 30th day after surgery was 14.0 mmHg, 13.2 mmHg,
12.03 mmHg and 11.76 mmHg respectively in group A, while
in group B corresponding values were: 9.0 mmHg, 8.97
mmHg, 8.83 mmHg and 8.9 mmHg. The shallowing of anterior
chamber and choroidal detachment were observed in 4 eyes
(13.8%) in group A and in 8 eyes (27.6%) in group B
postoperatively. The increased IOP during first days
after surgery was observed in 3 cases (10.3%) in group
A.
Conclusions: The viscoelastic agent left in the
anterior chamber at the end of trabeculectomy
significantly decreases the frequency of anterior
chamber shallowing and choroidal detachment and reduces
number of cases with hypotony. |
