ABSTRACT

Purpose: To determine the reproducibility of measurements of the retinal nerve fiber layer (RNFL) using two protocols of the Stratus OCT in glaucoma suspects.
Methods: Patients with diagnosis of glaucoma suspect were measured using Stratus OCT (Carl Zeiss). Two protocols of the OCT were compared during the same moment of the study: the fast RNFL and the normal RNFL analysis. Statistics was made through t-Student in the program SPSS.
Results: Seventy two eyes of 37 glaucoma suspects with a mean age of 59 ± 13.2 years were studied. Differences in the measurement of the RNFL were found in the superior quadrant using the fast RNFL protocol and the RNFL (121.5 µ vs. 115.9 µ, p 0.01). Parameters related to the superior quadrant were also different, with an increase of the RNFL using the fast protocol.
Conclusions: In our glaucoma suspect patients, fast RNFL protocol had a tendency to increase the measure of the RNFL, this similar finding was found in patients with glaucoma and healthy people.
