| Summary: |
Purpose: To
determine blood-flow parameters in extraocular vessels
in patients with primary open-angle glaucoma before and
after trabeculectomy.
Material and methods: Between November and
December 2002 in 18 patients (12 women and 6 men) with
primary open-angle glaucoma trabeculectomy was performed.
In preoperative period, 10 days after and between third
and sixth month after trabeculectomy, patients were
subjected to complete ocular examinaton and evaluation
of blood flow velocity (mean, systolic, diastolic) and
pulsation indexes in posterior ciliary arteries with
Doppler's focused pulsating ultrasonography. Based on
the results of the last examination patients were
divided in two groups before the treatment. Group A
included 9 patients (4 men and 5 women), age ranged from
46 to 77 (mean 63,67). Preoperative IOP in this group
ranged from 14,6 mmHg to 34,5 mmHg (mean 25,6 mmHg).
Blood-flow velocities were lowered in 9 patients for 20%
below the norm. Pulsation indexes ranged from 1,0 to 1,3
in 7 patients and from 1,3 to 1,5 in 2 patients. Group B
included 9 patients (6 women and 3 men) age ranged from
58 to 88 (mean 73,5). Preoperative IOP in this group
ranged from 14 to 44 mmHg (mean 27,24 mmHg). Blood-flow
velocities were lowered in 9 patients for 30-50% below
the norm and pulsation indexes were higher then 1,2.
Three of the 9 described patients had no velocities in
diastolic phase and pulsation indexes were higher than
2,0.
Results: Postoperative IOP in group A ranged from
7,1 to 17,3 mmHg (mean 11,0 mmHg). Four of the 7
described patients had velocities higher for 20-30% than
preoperatively and were normal. Pulsation indexes
lowered to 1,0-1,2. In 3 patients velocity increase was
observed later (after 6 months). In group B
postoperative IOP ranged from 4,9 to 14,6 mmHg (mean 8,6
mmHg). Velocity increase was observed and it reached the
lower limit of the norm or were higher. Pulsation
indexes lowered to 1,0-1,2.
Conclusion: The parameters of blood-flow in
posterior ciliary arteries improved in all cases after
trabeculectomy. |
