LONGITUDINAL AND CROSS-SECTIONAL ANALYSES OF VISUAL FIELD PROGRESSION IN PARTICIPANTS OF THE OCULAR HYPERTENSION TREATMENT STUDY

摘要

Research Objective To explore the agreement between longitudinal and cross-sectional analyses for determining visual field progression in data from the Ocular Hypertension Treatment Study. Study Design Data analysis. Location Multiple North American sites. Theoretically, if the MD is decreasing every year and the GH is stable, then the island of vision would have the same height but with a worsening localized scotoma. However, the investigators found that the MD and the GH were both decreasing every year in many patients, indicating mainly diffuse loss of the island of vision.
