Background
Aim of the study was the evaluation of a new form of perimetry (flimmer perimetery) compared to standard achromatic perimetry.
Methods
All glaucoma patients were examined randomised with two perimetric methods: flimmer perimetry (Pulsar, CP-T30W, TOP strategy, Haag-Streit) and standard achromatic perimetry (Octopus, G-1, TOP strategy, Haag-Streit). We analysed the Mean Defect (MD) and the Loss Variance (LV). The statistical analysis was done with non – parametric tests.
Results
We examined 25 glaucoma – patients: 12 patients with primary open angle glaucoma, 8 patients with pseudoexfoliatic glaucoma and 5 patients with intraocular hypertension. The mean age of all patients was 56±19.7 years. In comparison of all patients we obtained a statistical significant difference between MD-G1 (median ± mean absolute deviation OD 1.3± 4.2 dB, OS 1.1±4.3 dB) to MD-Pulsar (median ± mean absolute deviation OD 6.2±3.9 dB, OS 4.2±3.6 dB) and LV-G1 to LV-Pulsar on the right eye (OD) (p> 0.05), only.
Conclusions
The new flimmer perimetry (Pulsar) showed a statistical significant difference between the Mean Defect in Pulsar compared to the standard achromatic perimetry. Therefore, Pulsar seems to be more sensitive to visual field disturbances than standard achromatic perimetry..
