Light control devices and methods for regional variation of visual information and sampling

Abstract

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods may optically move, at a sampling rate between 50 hertz and 50 kilohertz, one or more apertures anterior to a retina between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of priority to U.S. Provisional Application No. 62 / 608,039, entitled “LIGHT CONTROL DEVICES AND METHODS FOR NOVEL REGIONAL VARIATION OF VISUAL INFORMATION AND SAMPLING”, filed Dec. 20, 2017, which is incorporated herein by reference in its entirety for all purposes.TECHNICAL FIELD[0002]The disclosed embodiments relate to light control devices and methods for regional variation of visual information and sampling.BACKGROUND[0003]The retina is the part of the eye that responds to light from an ocular field of view and converts the light to signals to begin image processing. Visual processing continues in the brain where the retinal visual information is integrated spatially, temporally and with ocular movements to achieve visual perception of the ocular field of view. An optical axis is a straight line perpendicular to the front of the eye and extending through a center of the pupil, defined herein as coaxi...

Benefits of technology

[0011]Further, the light control device also can include one or more microphones and at least one processor coupled to the one or more microphones. The at least one processor can be configured to execute software instructions to convert an audible speech to a text in a preferred language and to display the text within a field of view of a subject. In some examples, the light control device also can include one or more light emitting diodes placed around the perimeter of the field of view, and the processor can be further configured to execute the software instructions to energize selectively the one or more light emitting diodes to indicate a direction from which the audible speech is produced.

[0012]In further examples, a method includes utilizing a light control device. The device is configured to move optically one or more apertures anterior to a retina of an eye between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. The one or more apertures are moved at a rate between 50 hertz and 50 kilohertz, and the light control device produces a regional variation of visual information and sampling (V-VIS) of an ocular field of view.

[0013]Additionally, in some examples, anterior to the retina can include one of extraocular, intracorneal or intraocular placement, and the light control device can be configured to electro-optically move one or more apertures through one or more see-through displays placed anterior to the retina to produce the regional variation of visual information and sampling of the ocular field of view for at least one of vision, screening, customization, calibration, vision measurement, or vision monitoring. The light control device can also be configured to produce at least one of an improvement of vision in an eye or both eyes of a subject, a stabilization of vision in the eye or in both of the eyes of the subject, a correction of an ophthalmic or neurologic condition, an amelioration of a visual symptom in the eye or both of the eyes of the subject with the ophthalmic or neurologic condition, a disease, an injury or a disorder, a reduction of a rate of vision loss in the eye or both of the eyes of the subject with vision loss from the ophthalmic or neurologic condition, disease, injury or disorder, a reduction of a rate of progression of the ophthalmic or neurologic condition, disease or disorder in the eye or both of the eyes of the subject with the ophthalmic or neurologic condition,

Problems solved by technology

In eyes with retinal macular lesions, a stationary small aperture often does not improve visual acuity and often causes a reduction in visual acuity by restricting light to dysfunctional areas of the retina.

Stationary small apertures in only one eye of a subject induce anisocoria and produce detrimental interocular differences in visual latency causing hazardous distortions of relative movement.

Conventional treatment for amblyopia, unlike some embodiments of these exemplary V-VIS devices and methods, decreases the number of spatial samples, particularly in the periphery, availabl
