The purpose of this investigation was to measure visual acuity (VA) and functional contrast sensitivity (FCS) as a function of age in a large sample of normal subjects and to establish reliable, statistical limits to describe normal vision....
Reproducibility of near visual acuity measurements depends on the age and co-operation of the child and the method used. The choice for a method should be based on the developmental level of the child. This systematic review will provide guidelines for near visual acuity measurements for 0-3 ...
Methods Military recruits with best eye uncorrected visual acuity 0.00 LogMAR or better, normal colour vision and age 18–25years were included in a study to record contrast sensitivity using Optec 6500 (FACT) at spatial frequencies of 1.5, 3, 6, 12 and 18cpd in photopic and mesopic light ...
Visual acuity and many other visual functions are not affected by congenital colour deficiency. In congenital deficiency the loss of colour vision is binocular, symmetrical and stable over time. Congenital colour vision deficiencies arise largely as a result of changes in the properties of L, M and...
The purpose of the study was to determine the normal values for the performance of five age groups (20 - 29, 30 - 39, 40 - 49, 50 - 59, and 60 - 69 years) in the letter search (LS) test. The LS test is a multiple-fixation visual-search task, in which the subject is require...

They are typically standardized tests that cover a wide range of questions including logical, visual, spatial, classification, analogical, and pattern-driven questions. The IQ is determined by the deviation between the test score and the average test score of people of your age. IQ is considered...
The aim of the study was to assess different visual acuity tests in the age group 1陆-6 years in 105 children with assumed normal vision, visual impairment... Agneta,Rydberg,Birgit,... - 《Strabismus》 被引量: 63发表: 1999年 Vernier acuity is selectively affected in infants and children ...
Results: Mean age was 8,9 in strabismic ambliyopes 8,7 in anisometropic ambliyopes and 12,3 in control group (p>0,05). Mean corrected visual acuity for amblyopic eyes was 0,46 in strabismic ambliyopes and 0,41 in anisometropic ambliyopes (p>0,05). Contrast sensitivity functions ...
Methods Twelve deaf subjects (average age 16.5) and 15 normal hearing subjects (average age 23.7) were stimulated by 4 kinds of luminance contrast (0.7, 2.2, 50.0, 180.0 lm). The fMRI data were collected on GE 1.5 T Signa Horizon LX MRI system and analyzed by AFNI to generate the ...
