USA: True functional change precedes thinning of retinal nerve fiber layer (RNFL) in glaucoma, suggests a recent study in the journal Investigative Ophthalmology & Visual Science.
Previous studies have suggested structural change to be detectable before functional change in glaucoma. However, this may be related to the lower variability and hence narrower limits of structural tests. In this study, Stuart K. Gardiner, Devers Eye Institute, Legacy Research Institute, Portland, Oregon, United States, and colleagues determined whether a time lag exists between the true rates of change in structure and function, regardless of clinical detectability of those changes.
