- Abstract:
- We conducted comparative measurements with 100 healthy probands and patients suffering of glaucoma with both a Goldmann Applanation Tonometer (GAT) and the new Keeler Non Contact Tonometer (NCT). A noticeable conformity of mean values in the group I with values under 23 mm Hg and in group II with values greater or equal 23 mm Hg was obvious. The results of three NCT measurement values were compared with those of four measurements. The Keeler NCT nearly fulfills the needed criteria for the first group with pressure under 23 mm Hg except for a high standard deviation. In group II (pressure greater or equal 23 mm Hg) the demanded nominal values are exceeded.
