Despite a remarkable progress in the understanding of the constrains imposed on bathyergid visual capacities by their minute eyes and a reduced visual system (for review, see [7], [8]), the biological significance of vision in the natural environment of the bathyergid mole-rats is uncertain.
Interestingly, the W890R CASK variant [referred to as W919R by Hackett et al. (8)] was associated with milder visual impairment (none of the affected patients had a reduced visual acuity) in comparison with the other nystagmus-associated CASK mutations (8).
In our experiments, high load reduced auditory detection accuracy by 26%% and detection sensitivity by 1.6, on average, whereas Macdonald and Lavie (2008) found that the same manipulation of load reduced visual detection accuracy by 32%% and detection sensitivity by 1.5, on average (across their Exps. 1 5).
Lesions in any of these areas are followed by absent or reduced visual threat responses.
Patients with LCA caused by mutations in CEP290 have reduced visual perception, although they present with a fully laminated retina.
The contact lens reduced visual acuity by an average of 17 letters (median logMAR=−0.34; p<0.01) and reduced contrast sensitivity by an average of 7 letters (median logCS=0.36; p<0.01) (table 1).
But I am concerned that three things are slowing the natural evolution of cinema the eminence of the "event film" (already discussed), our obsessive insistence on a paraphrasable narrative, and the reduced visual attention span caused by over-consumption of television.
Achromatopsia (ACHM) is an early-onset retinal dystrophy characterized by photophobia, nystagmus, color blindness and severely reduced visual acuity.
Overall, when we reduced visual similarity by having four more varied exemplars in Experiment 2, we found no evidence that the key distractor on category-match trials affected attention, regardless of the task.
Case-patients were followed up after exposure to either of the 2 Franck's products for either 6 months or until documented resolution of infection, whichever occurred first; vision loss in this analysis reflects documentation of reduced visual acuity by the treating ophthalmologist at any point during this 6-month period and not necessarily permanent vision loss.
