This study embodies and proposes VR color therapy healing contents 'Nornir' that can manage stress in daily life. " Nornir" applies the CRR analysis method to provide a customized VR color therapy experience according to the three colors selected by the user. It is designed to enable users to understand themselves through their color journey, to rec eive various color interactions and stimuli to implement in the future, and to provide healing that lowers stress levels. Based on the results implemented, the Korean version of the mood condition test 'K-POMS' was conducted before an d after the demonstration to check the user's stress changes after the content demonstration. Experiments have shown that users clearly see a decrease in negative emotions and an increase in positive emotions. By using VR technology, color psychotherapy rules are combined to provide the possibility of relieving stress for users who are exposed to fre quent stress in daily life.

Purpose: To evaluate of usefulness of retinal nerve fiber layer thickness as measured by optical coherence tomography (OCT) in children and young adolescents in the diagnosis of glaucoma, ocular hypertension, and glaucoma suspect. Methods: In total, 234 patients aged <18 years were included in this study (21 eyes with glaucoma, 179 suspected glaucoma eyes, and 34 eyes with ocular hypertension). All patients underwent OCT to measure the retinal nerve fiber layer thickness, Humphrey visual field testing if possible, and other ocular examinations. Based on the OCT results, we classified the eyes into 4 o'clock-hour and 12 o'clock-hour sectors and compared these data with other clinical ocular findings. Results: The retinal nerve fiber layer thickness as measured by OCT was correlated with the vertical cup disc ratio. An OCT 330° (Sup) value of <140 µm or an average OCT value of <105 µm is useful for the prediction of a vertical cup disc ratio of >0.6. Conclusions: A higher vertical cup disc ratio is associated with a lower retinal nerve fiber layer thickness, not only with back-bowing of the lamina cribrosa or normal variation. An OCT 330° (Sup) value of <140 µm or average OCT value of <105 µm is a useful index with which to predict early glaucomatous changes in pediatric and young adolescent patients.
