We evaluated the full field electroretinogram (ERG) to assess age-related changes in retina function in humans. ERG recordings were performed on healthy subjects with normal fundus appearance, lack of cataract and 20/20 acuity, aged 20-39 years (n = 27; mean age 25 ± 5, standard deviation), 40-59 years (n = 20; mean 53 ± 5), and 60-82 years (n = 18; mean 69(More)
The most widespread models to study blindness, rats and mice, have retinas containing less than 3% cones. The diurnal rodent Arvicanthis niloticus retina has around 35% cones. Using ERG recordings, we studied retina function in this species. Several features differed from that reported in rats and mice: (a) fivefold larger photopic a-wave amplitudes; (b)(More)
Data on stage, grade and morphology of 12,761 colorectal cancers registered between 1995 and 2003 by Oxford Cancer Registry are reviewed. Dukes stage is recorded for 81% of colon cancers and for 69% of rectal cancers. Incomplete registry data and changing recording practices may affect future evaluation of bowel cancer screening.
