Unfortunately, although Cortese is backing up his vision with continuing levels of investment in training facilities that already rank among the best, there are no Xavis or Iniestas with Hampshire accents on the verge of a first-team breakthrough.
In WDRS, 18% had vision-threatening levels of retinopathy vs. 43% in WESDR.
These improvements in vision-specific QOL resulted in decreased levels of vision-related dependency for ranibizumab compared with sham-treated patients (Chang et al. 2006).
Our findings indicate that those developing and implementing a comprehensive breast cancer control strategy should have a single vision in mind, irrespective of country size or level of development.
While rods are used for vision in low light levels, and double cones (composed of two cells in close electrical and physical contact) are thought to mediate achromatic tasks (luminance or brightness perception), colour vision in diurnal birds depends on the four types of single cones, that are sensitive to very short (VS), short (S), medium (M), and long (L) wavelengths respectively [24].
Jonathan Wyatt, the first patient in the world to be treated with the gene therapy, now has double the level of vision in his treated left eye, which has been maintained for four years so far.
The selection criteria were (i) normal or corrected-to-normal vision and (ii) acceptable level of accuracy in detecting single target stimuli, in both the screening and main RSVP tasks (see procedure for details).
Less-severe levels of vision impairment have been categorized, ranging from near-normal vision to various degrees of low vision to near-blindness, depending on the visual acuity and functional impact stemming from the vision loss.
Furthermore, it is difficult to statistically analyse differences in Snellen visual acuity following treatment, especially at low levels of vision.
Rural Sussex in 2008 is some way from California in the early 1900s, but we are seeing similar levels of tunnel vision there, again in pursuit of oil.
