Stereopsis and aniseikonia in uniocular aphakia.

Uniocular aphakia in the adult when corrected with a contact lens is in most patients no obstacle to binocular function. The long-term result is a balance between binocular function obtained and the comfort of the contact lens, and in this respect the advent of the soft lens, and especially the continuous-wear lens, appears to be most promising.

Retinal irradiation and aniseikonia.

Differences in tests of aniseikonia.

The New Aniseikonia Test (NAT), a hand-held direct-comparison test using red/green anaglyphs, has several potential advantages as a screener. We compared the validity of the NAT to that of the Space Eikonometer in three experiments: (1) aniseikonia was induced by calibrated size lenses in a double-blind study of 15 normal subjects; (2) habitual aniseikonia was measured with both instruments in ...

This paper continues the assessment of the long-term merits and problems of intraocular acrylic lenses which was started by a consideration of the value of the Binkhorst iris clip lens in aphakia by Pearce (I972). The reduced degree of aniseikonia and the better opportunity for binocular vision when uniocular aphakia is corrected by an intraocular lens implant was emphasized by Girard, Friedman...

Aniseikonia associated with epiretinal membranes.

AIMS To determine whether the computerised version of the new aniseikonia test (NAT) is a valid, reliable method to measure aniseikonia and establish whether aniseikonia occurs in patients with epiretinal membranes (ERM) with preserved good visual acuity. METHODS With a computerised version of the NAT, horizontal and vertical aniseikonia was measured in 16 individuals (mean 47 (SD 16.46) year...
