| Summary: |
The purpose of the study
was to compare the findings of confocal scanning laser
ophthalmoscopy (HRT) and GDx Nerve Fiber Analyzer in
eyes with ocular hypertension. Twenty two patients with
ocular hypertension were included in the study. All
patients had IOP between 21-28 mmHg, open angles in
gonioscopy examination and no visual field defects in
automated perimetry. The HRT and GDx-NFA imaging were
completed from 1 eye from each subject in a 3-months
interval. GDx results (TSINT Average, Superior Average
and Interior Average) were correlated with HRT nerve
head topographic measurements (DA, RA, RV, mean RNFL
thickness) in whole disc area, superior and inferior
pole. The number in GDx advanced analysis had a
significant (p < 0.05) correlation with rim area, rim
volume and mean RNFL thickness. The greatest
significance was found for TSNIT Average and RV
(p<0.001, r=0.745). The correlation between HRT
stereometric parameters and GDx advanced analysis
parameters was more significant for parameters targeting
the superior pole of the disc than the inferior pole. |
