To compare OCT measurements of the foveal and perifoveal thickness obtained by fast macular and radial lines protocols in normal eyes.
Normal eyes with refraction errors between +4.00 and -6.00 were submitted to OCT Stratus examination through undilated pupils. Fast macular thickness and radial lines protocols were used. Thickness measurements were done using OCT automated toll. Foveal and perifoveal temporal, nasal, superior, and inferior thickness were recorded. Statistical analysis was performed using the student-t test, and p <0,05 was considered statistically significant.
One hundred eyes of 100 patients were evaluated. Mean age was 34.1 years. Mean thickness for fast macular and radial lines were respectively: foveal: 204.1µ and 201.2 µ (p=0.00016); perifoveal superior: 281.6 µ and 282.0 µ (p=0.36); perifoveal temporal: 267.4 µ and 267.8 µ (p=0.59); perifoveal inferior: 282.0 µ and 282.0 µ (p=0.96); perifoveal nasal: 281.2 µ and 282.5 µ (p=0.18).
Foveal thickness measured by the fast macular protocol was statistically significant higher than measured by the radial lines protocol. The other perifoveal measurements were statistically significant equivalent.
