Özet
Background: To examine the correlation between Humphrey visual field analyzer and an automated virtual reality perimetry test (Oculera visual field analyzer) in glaucoma patients and healthy individuals. Methods: This prospective, single-center study was conducted on 93 eyes of 93 patients, 55 of whom were glaucoma patients (glaucoma group) and 38 healthy subjects (normal group). HFA II (24-2, Swedish Interactive Threshold Algorithm) and Oculera (24-2, Oculera Interactive) tests were applied to all participants. Mean deviation (MD), pattern standard deviation (PSD), and visual field index (VFI) values of both devices were obtained. The correlation between the two devices was evaluated by statistical analyses of MD, PSD, and VFI. Results: The MD values were −6.36 dB (−31.8 to 2.27) for HFA II and −5.80 dB (−29.1 to 2.2) for Oculera. The difference between MDs of Oculera and HFA II was −0.56 dB. Wilcoxon signed-rank test showed a statistically significant difference in MD values between Oculera and HFA II (p < 0.001). However, there was a strong correlation between MDs (r = 0.932 and p < 0.001). With this, the results of the Bland-Altman analysis evaluating the agreement between the two tests showed that the differences between the MD measurements were not within the acceptable error range and that the results of the devices could not be used interchangeably. A strong correlation was found between the two devices in terms of PSD and VFI values (r = 0.752, r = 0.910, respectively). Conclusions: The current findings are promising for the future use of Oculera in the diagnosis and follow-up of glaucoma patients.
