In recent years, remote sensing, morphometric analysis, and other computational concepts and tools have invigorated the field of geomorphological mapping. Automated interpretation of digital terrain data based on impartial rules holds substantial promise for large dataset processing and objective landscape classification. However, the geomorphological realm(More)
The direct and consensual accommodation of both eyes were determined by a modified coincidence refractometer. Young individuals with normal monocular and binocular vision revealed a close quantitative correspondence between the direct and the ipsi- and contralateral consensual accommodation. Experimental impairment of the function of the ciliary muscle by(More)
The immanent sense of optic orientation in space is related to the unchangeable line of principal visual direction and its collaterals. Therefore in patients with loss of central vision due to organic lesion the orientation in space is impaired as well. as a result of a vicious circle of indistinct vision, eccentric fixation and suppresion of foveal(More)
Objective determination of accommodation in 38 children with permanent central scotoma due to amblyopia on one side (with central and eccentric fixation) revealed: 1. The physiological adaptation of refraction for far and near distances did not serve its purpose. 2. There was either no or an irregular response on hyperopia, which was produced by placing(More)
Objective determination of monocular accommodation in young eyes revealed a different behaviour in strabismus alternans from that in normal binocular vision. This manifested itself by strongly differing individual responses, less correct values in physiological and unphysiological accommodation tests, and different reactions on hindering clear vision that(More)
Variations in the area of the insertions of the rectus muscles are quite often observed. We have been paying more attention to these changes during the past year, and therefore we measured the distance of insertion from the corneal limbus during 310 squint operations. Furthermore we noted the width of the tendon at the insertion, atypical forms of(More)
