Introduction
The aim of this study is an evaluation of retina thickness in macula region in healthy subjects, by using retina thickness analyzer RTA and determination of gender and age relationships of the retina thickness.
Material and methods
Eighty healthy subjects (155 eyes), 24 to 70 years old (average age 45.7 years), underwent full ophthalmologic examination and also retinal thickness analysis with RTA analyzer. In particular, foveola average thickness VAV, foveal average thickness FAV, peri-foveal average thickness PFAV and posterior pole average thickness PPAV, were determined. The data were statistically evaluated.
Results
Average values of VAV (163.6 ± 21.7 μm), FAV (172.4 ± 19.0 μm), PFAV (199.2 ± 14.2 μm) and PPAV (194.5 ± 12.8 μm), were determined. No statistically significant differences between male and female groups and between right and left eyes were found. The retinal thickness increased slightly with age but the regression analysis revealed no significant linear correlation between any of the parameter values and age.
Conclusions
The retinal thickness in macula region in Polish healthy subjects did not differ substantially from the world literature data.
