| Outline of Final Research Achievements |
Even in the patients with open angle glaucoma (OAG: primary open angle glaucoma and normal tension glaucoma), major part of visual quality of life (QOL) depends on visual acuity. We found that visual field sensitivity in the papillo-macular area, had to be maintained to keep patients’ visual acuity in OAG. En-face images obtained by OCT show the specific pattern of the retinal nerve fiber bundles in OAG patients with good visual acuity. Using this technic, we can estimate visual field in the central 10 degrees from the results by OCT examination.
We performed a questionnaire to evaluate visual QOL, VFQ-25, for OAG patients, and made Rasch scoring. In addition, we developed HDIVF (high density integrated visual field) score by combination of the HFA 24-2 and 10-2 results in both eye. We found that HDIVF score was one of the best indexes to evaluate visual QOL in OAG patients because of strong correlation with the Rasch score of VFQ-25.
