| Summary: |
Purpose: The
comparative evaluation results of frequency doubling
technology (FDT) in healthy subjects, in patients with
glaucoma suspected and glaucoma, as well as analysis
influences of selected risk factors onset, and
progression of glaucoma (age, gender, intraocular
pressure, refractive errors, circulation system disease,
diabetes mellitus, vasospastic vascular disease) on
FDT-parameters.
Material and methods: Sixty four patients (128
eyes), in age between 13-80, with refraction error from
-14,5 to +6,5 D sph and average intraocular pressure
19,8 ± SEM were included in this study. All patients
were previously diagnosed towards glaucoma. The visual
field testing with help of FDT Visual Field Instrument
were made at least triple at all patients, with
capitalize on the THR N-30 threshold program. Global
indices: mean deviation (MD) and pattern standard
deviation (PSD) and numerical value of mean retinal
sensitivity for central visual field 5o sector (mean
sensitivity to central 5 degrees - MS 5o) come in
comparative analysis. All data were analyzed by chi2 and
Kruskal-Wallis tests.
Results: Comparative analysis examined groups of
healthy persons, patients with glaucoma suspect and
glaucoma, it proves statistically significant difference
between MD, PSD and MS 5o. Statistically no significant
difference between PSD and MS 5o at groups of healthy
and glaucoma suspect patients was detected.
In glaucoma group there did not reveal an influence on
selected risk factors on FDT parameters. However, in
glaucoma suspect group revealed an influence on most
risk factors on perimetry parameters.
Conclusions: FDT is useful for detection of
glaucomatous nerve fiber damage. There should be taken
precautions of interpretation FDT results at glaucoma
suspect patients. |
