New methods of interpreting RNFL thickness, visual field detects glaucomatous change earlier

KOLOA, Hawaii – Longitudinal data collected recently supports the structure-function relationship in glaucoma progression in which the retinal nerve fiber layer thins to a point where it and visual field begin to worsen simultaneously, a presenter said here. “Structure generally changes without changes in visual fields early in glaucoma,” Joel S. Schuman, MD, said during the glaucoma section of the Hawaiian Eye meeting. In other words, during this early part of the curve, abnormality is measurable primarily by structure, he said.
