title: [The endothelin-1 level in blood serum of patients with primary open angle glaucoma abd its influence on the static perimetry abd Gdx changes].
abstract: OBJECTIVE
  The aim of the work was to define the relationships between the endothelin-1 level in blood serum of glaucoma patients concerning the visual field defects and the number of nerve fibers.
  
  
  METHODS
  24 women and 14 men, aged 38-74 year (mean 53.4 year) with primary open angle glaucoma, without any systemic diseases. The control group consisted of 20 healthy women and men, aged 34-70 year (mean 52.6 year). The endothelin-1 level was tested with the enzymo-immunologic method from the blood serum. The visual field defects were examined with the Humphrey static perimetry. The nerve fibers were analyzed with the Gdx apparatus.
  
  
  RESULTS
  Mean value of ET-1 in blood serum were similar in both examined groups, it was 0.51 in group of glaucoma patients and 0.54(fmol/l) in the control group. There were no significant correlations between ET-1 level, static perimetry, GDx parameters and age in the group of patients with POAG. The statistics significances were stated for ET-1 level and MD-parameter in static perimetry (p < 0.03) and ET-1 level with The Number--the GDx parameter (p < 0.03).
  
  
  CONCLUSIONS
  There was no significant level of ET-1 in blood serum in group of patients with POAG. There have not been stated any relationships between the static perimetry and GDx changes in patients with POAG to endothelin-1 level in blood serum. It is the preliminary communication.
