Change of Binocular Fusional Area with Retinal Shift

Area of binocular vision in anomalous retinal correspondence.

SEVERAL authors (Lyle and Foley, 1955; Naylor, Shannon, and Stanworth, 1956; Naylor and Stanworth, 1959; Guzzinati and Salvi, 1957; Pasino, Maraini, and Santori, 1963) have observed the absence of a stereoscopic perception of depth in early convergent strabismus with anomalous retinal correspondence. Even in patients with an extremely small fixed ocular deviation and harmonious anomalous retina...

Bio-inspired Binocular Disparity with Position-Shift Receptive Field

Depth perception starts with the binocular interaction receptive fields of simple cells modeled by two Gabor functions followed by a half-squaring function. Simple cells do not have reliable disparity computation. Complex cells combine two simple cells in quadrature. They are better adapted to encode disparity information. The image disparity can be determined by fixing the receptive field in o...

Binocular coordination during reading of blurred and nonblurred text.

PURPOSE Reading a text requires vergence angle adjustments, so that the images in the two eyes fall on corresponding retinal areas. Vergence adjustments bring the two retinal images into Panum's fusional area and therefore, small remaining errors or regulations do not lead to double vision. The present study evaluated dynamic and static aspects of the binocular coordination when upcoming text w...

Effect of preoperative posture and binocular occlusion on retinal detachment.

In an unselected series of retinal detachments a 24-hour period of binocular occlusion and posture with a retinal hole dependent produces some resolution of subretinal fluid in 13% of cases. If only patients with acute, freely mobile detachments and retinal holes above the horizontal meridian were selected the proportion of detachments showing some resolution rose to 30%. In 8% of cases a parad...
