Monocular Visual Confusion for Field Expansion

Massachusetts Eye and Ear Infirmary·interventional·Posted Jul 12, 2021·Updated Jul 10, 2023

In Brief

A clinical study evaluating Binocular visual confusion (unilateral opaque), Unilateral monocular visual confusion (unilateral see-through), and 1 other intervention for Diplopia and 3 related conditions. Completed, enrolled 13 participants across 1 site.

Detailed Summary

In this research study we want to test how people understand a visual scene when the same image is presented to both the eyes, but portions of these images are altered in terms of contrast, depth or in some cases motion.

Interventions

Binocular visual confusion (unilateral opaque)behavioral

The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For the binocular visual confusion condition, the non-transparent (opaque) peripheral target will be displayed on only one eye (unilateral opaque display).

Unilateral monocular visual confusion (unilateral see-through)behavioral

The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For the unilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on only one eye (unilateral see-through display).

Bilateral monocular visual confusion (bilateral see-through)behavioral

The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For bilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on both eyes (bilateral see-through display).
