Summary: Purpose: Aim of the study is a comparison of retinal thickness values in macular region in healthy individuals using retina thickness analyzer RTA and optical coherence tomography (OCT).
Material and Method: Seventeen healthy subjects (33 eyes) 30 to 58 years old (average age 42.6 years) underwent complete ophthalmologic examination and also retinal thickness analysis with RTA and OCT analyzers. In particular, foveal average thickness, peri-foveal average thickness and posterior pole average thickness were determined. The data were statistically evaluated.
Results: The average values of foveal average thickness (RTA 165.5 ± 14.3 µm; OCT 237.0 ± 20.7 µm), peri-foveal average thickness (RTA 189.0 ± 14.4 µm; OCT 289.4 ± 13.6 µm) and posterior pole average thickness (RTA 183.8 ± 13.7 µm; OCT 269.0 ± 10.9 µm) were different with statistical significance. The RTA retinal thickness values were higher than those determined by OCT. A linear correlation between the RTA and OCT values was established.
Conclusions: The retinal thickness in macular region measured by RTA is lower than that measured by OCT. The difference is statistically significant.
