Testing macular letter recognition ‐ reliability and influence of refraction errors

Macular hole and myopic refraction.

AIM To study a correlation between age at the onset and myopic refraction and axial length in patients with idiopathic macular hole and to evaluate a correlation of the size and surgical outcome of macular hole with axial length. METHODS In a prospective clinical study, 94 eyes of 91 patients with stage III and IV idiopathic macular hole were enrolled. A standardised surgical protocol was per...

Errors of Refraction and Their Sequele

In theory no doubt any existing refractive error should be found and treated, so that the individual may enjoy the most perfect optical conditions possible. But it must always be borne in mind that the eyes are only part of the living organism, dependent on the whole, deriving from it and adding to it. This may modify the position. A comfortable and efficient ocular mechanism depends on much mo...

Modes of inheritance of errors of refraction.

Eighteen families in which both parents had refractions within the range of + 4 0 D to 4 0 D and axial lengths seen in emmetropia (22.3-26-0 mm) showed coefficients of correlation of the order 0 5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0.407) and for the cornea (0-487), but not for the lens (which is known to be yoked to the axial length). No such coe...

What do letter migration errors reveal about letter position coding in visual word recognition?

Dividing attention across multiple words occasionally results in misidentifications whereby letters apparently migrate between words. Previous studies have found that letter migrations preserve within-word letter position, which has been interpreted as support for position-specific letter coding. To investigate this issue, the authors used word pairs like STEP and SOAP, in which a letter in 1 w...
