| Summary: |
Purpose: To compare
the results of conventional suprathresold automated
static perimetry (SASP) and a new method of kinetic
visual field examination (semi-automated kinetic
perimetry – SKP) in patients with advanced retinal nerve
fibre layer (RNFL) defects, caused by glaucoma.
Material and methods: Nineteen patients (10 women
and 9 men) suffering from advanced open-angle glaucoma
(17 patients) and low tension glaucoma (2 patients) were
enrolled in this study. The mean age was 65,3 years (range
49,0-82,9 years). One eye of each subject was examined
with SKP and SASP, both implemented in Octopus 101
perimeter (Haag-Streit, Koeniz, Switzerland) on the same
day. The examiner using SKP did not know the SASP
results. The static visual field examination was
performed first. In order to compare visual fields
results obtained with both methods, only central 30o
area of the visual fields was taken into consideration.
The area obtained by creating a virtual isopter (option
of SKP software) located between the position of
defective and intact visual field regions of SASP and
the area of I4e isopter obtained with SKP (stimulus
angular velocity 3o/s) were measured in deg2 and
compared.
Results: The mean area (±SD) of I4e isopter
obtained with SKP was 1882 deg2 (± 510 deg2) and the
mean area of SASP 30o visual field was 1737 deg2 (± 546
deg2). This difference was not statistically significant.
Conclusion: Quantitative comparison of static and
kinetic perimetry is a difficult task to perform. The
SKP software offers a possibility of direct quantitative
assessment of the area of each isopters in deg2. This
study shows that the results of visual field
examinations obtained with both methods in this group do
not differ significantly between SASP and SKP. |
