Journal ArticleDOI
Retinopathy in old persons with and without diabetes mellitus: the Age, Gene/Environment Susceptibility--Reykjavik Study (AGES-R).
Elin Gunnlaugsdottir,Sigrun Halldorsdottir,Ronald Klein,G. Eiriksdottir,Barbara E.K. Klein,Rafn Benediktsson,T.B. Harris,L. J. Launer,Thor Aspelund,Vilmundur Gudnason,M. F. Cotch,Friðbert Jónasson +11 more
TL;DR: Over three-quarters (78%) of retinopathy cases were found in persons without diabetes and a strong association between microalbuminuria and non-diabetic retinitis was found, which may have implications for patient management of the aged.
Journal Article
Correlates of lens thickness: the Beaver Dam Eye Study.
TL;DR: Age was the most significant personal characteristic associated with lens thickness among those subjects considered and other characteristics, including specific cataract types and risk factors for cataracts, also were associated with thickness.
Journal ArticleDOI
Imaging the response of the retina to electrical stimulation with genetically encoded calcium indicators
Andrew C. Weitz,Matthew R. Behrend,Nan Sook Lee,Ronald Klein,Vince A. Chiodo,William W. Hauswirth,Mark S. Humayun,James D. Weiland,Robert H. Chow +8 more
TL;DR: In this article, a method for labeling the majority of ganglion cells in adult rat retina with genetically encoded calcium indicators, specifically GCaMP3 andGCaMP5G, was presented.
Journal ArticleDOI
Changing incidence of lens extraction over 20 years: the Beaver Dam eye study.
TL;DR: In the Beaver Dam Eye Study as discussed by the authors, the authors investigated trends in the incidence of lens extraction over the past 20 years, and found that the increased incidence in surgery was preceded by poorer visual acuity, near vision, or contrast sensitivity at the beginning of each interval.
Journal ArticleDOI
The relationship of retinal vessel diameter to changes in diabetic nephropathy structural variables in patients with type 1 diabetes
Ronald Klein,Michael D. Knudtson,Barbara E.K. Klein,B. Zinman,Robert Gardiner,Samy Suissa,Alan R. Sinaiko,Sandra Donnelly,Paul Goodyer,Trudy Strand,Michael Mauer +10 more
TL;DR: Independently of other factors, baseline CRAE correlated with changes in glomerulopathy index, a composite measure of extracellular matrix accumulation in the mesangium and glomerular basement membrane, and a narrowing of the CRAE was related to mesangial matrix accumulation.
