| Summary: |
Purpose: To examine
the influence of intraocular pressure (IOP) decreasing
after trabeculectomy on the retinal nerve fiber layer
thickness (RNFL) in glaucoma in the youth.
Material and methods: Nineteen eyes of 12
patients at the age from 10 to 18, mean 13,6 years,
treated for juvenile glaucoma were examined. All of them
were operated on performing trabeculectomy. Before
trabeculectomy and mean 14,9 months after operation IOP
was measured and the RNFL thickness with laser scanning
polarimeter GDx was estimated.
Results: Values of IOP before surgery ranged from
23 to 28, mean 25,3 mmHg and after surgery ranged from
12 to 24, mean 14,3 mmHg. Symmetry and superior integral
did not change, p = 0,96 after surgery. Average
thickness of RNFL before operation was 60,61µm and after
surgery 63,09µm, p = 0,06, superior average 74,14 µm and
78,33 µm, p = 0,06, inferior average 70,54 µm and 72,42
µm relatively p = 0,14.
Conclusions: Decreasing IOP after trabeculectomy
allows to maintain preoperative values of retinal nerve
fiber layer thickness in eyes with juvenile glaucoma. |
