Abstract

PURPOSE
To evaluate the relationship between optic disc and retinal nerve fiber layer (RNFL) measurements obtained by Heidelberg retina tomography (HRT) and Optical coherence tomography (OCT) in normal and primary open angle glaucoma (POAG). METHODS: Thirty normal and 100 POAG subjects who met inclusion and exclusion criteria were evaluated retrospectively. Complete ophthalmologic examination, HRT, OCT, and automated perimetry were performed. RESULTS: In POAG group, rim area was significantly correlated with superior and inferior RNFL thickness (p<0.05), and cup shape measure was correlated with mean, superior, inferior, temporal RNFL thickness (p<0.05). Inferior RNFL thickness was correlated with many HRT parameters (cup area and cup/disc ratio, rim area, cup volume, rim volume, cup shape measure, mean RNFL thickness) and visual field index (MD and CPSD) (p<0.05). CONCLUSIONS: Inferior RNFL thickness measured by OCT was correlated with optic disc parameters and visual field index measured by HRT and automated perimetry. It may be used as indicator of glaucomatous optic disc change and visual field defect. These findings suggest that optic disc parameters and RNFL thickness measured by HRT and OCT may be helpful in diagnosing glaucoma.
