30 results about "Visual acuity loss" patented technology

Loss of visual acuity in one eye: Loss of visual acuity in one eye refers to the loss of sharp, clear vision in one eye. See detailed information below for a list of 14 causes of Loss of visual acuity in one eye, Symptom Checker, including diseases and drug side effect causes.

Restoration of visual responses by in vivo delivery of rhodopsin nucleic acids

Nucleic acid vectors encoding light-gated cation-selective membrane channels, in particular channelrhodopsin-2 (Chop2), converted inner retinal neurons to photosensitive cells in photoreceptor-degenerated retina in an animal model. Such treatment restored visual perception and various aspects of vision. A method of restoring light sensitivity to a retina of a subject suffering from vision loss due to photoreceptor degeneration, as in retinitis pigmentosa or macular degeneration, is provided. The method comprises delivering to the subject by intravitreal or subretinal injection, the above nucleic acid vector which comprises an open reading frame encoding a rhodopsin, to which is operatively linked a promoter and transcriptional regulatory sequences, so that the nucleic acid is expressed in inner retinal neurons. These cells, normally light-insensitive, are converted to a light-sensitive state and transmit visual information to the brain, compensating for the loss, and leading to restoration of various visual capabilities.

Laser system with short pulse characteristics and its methods of use

ActiveUS20060187978A1Reduce thermal effectsShort and controlled pulse width trainsLaser surgeryLaser detailsPulse characteristicsRetinal damage
A laser system that includes a diode pump source. A frequency doubled solid state visible laser is pumped by the diode pump source and produces a pulsed laser output with a train of pulses. Resources provide instructions for the creation of the pulsed output, with on and off times that provide for substantial confinement of thermal effects at a target site. This laser system results in tissue specific photoactivation (or TSP) without photocoagulation damage to any of the adjacent tissues and without causing full thickness retinal damage and the associated vision loss.

Method and apparatus for performing microcurrent stimulation (MSC) therapy

A method and apparatus for providing microcurrent stimulation (MSC) therapy. In accordance with the present invention, it has been determined that the application of microcurrent signals at particular frequencies to the eye for particular periods of time stabilizes and even improves conditions of macular degeneration and other ocular diseases. Experimental data from clinical trials shows that results of persons who underwent therapy are at least better than placebo, and that the therapy is safe and efficacious. In fact, experimental data from clinical trials showed that approximately 98% of the patients who underwent the MCS therapy of the invention experienced either stabilization or improvement of macular degeneration within one year of starting therapy. Of this percentage, approximately 65% of the patients subjected to the MCS therapy experienced improved vision, while approximately 32% experienced stabilization of macular degeneration (i.e., no further loss of vision).

System and method for sensory defect simulation

A visual defect simulation system receives a functional field map produced by an MRI system that relates locations in a patient's brain to locations in the patient's field of view. Planned medical operations are indicated at locations in the patient's brain and any resulting vision loss is simulated with a revised functional field map. A scene is displayed and an impairment overlay is produced from the revised functional field map that blocks the scene at locations corresponding to simulated vision loss. The overlay is translated over the scene in response to viewer eye movements detected by a vision-tracking system to present a real-time simulation of the resulting vision loss.

Metamorphopsia testing and related methods

A visual distortion test is disclosed using a sequence of binary interactions with a mobile device, in which segments of the grid having no distortions are eliminated, and the segments with distortions are divided into smaller segments for further analysis. The test can quantify the visual distortion using a decreased number of steps, compared to sequential analysis of all the segments of the grid. The binary interaction or input to the mobile device is also easier for patients than graphic interactions with a conventional Amsler Grid. Early detection of changes in the visual distortion can enable the healthcare provider to individualize treatment, helping to prevent vision loss while minimizing visits to the office, discomfort, and expense.

Method for laser treatment for glaucoma

ActiveUS10744034B2Reduce convexityEnlarging the drainage angleUltrasound therapyLaser surgeryOcular tensionDrainage angle
Because vision loss in most forms of glaucoma is related to elevated IOP, most glaucoma treatment protocols are concerned with lowering IOP by increasing aqueous humor outflow. The invention utilizes electromagnetic radiation to create retraction in the iris tissue, thereby (a) reducing convexity and enlarging the drainage angle and thus the area of the anterior chamber, (b) reducing contact between the zonule fibers and the iris pigment epithelium, (c) applying greater tension to both the TM and uveoscleral outflow pathways, thereby enlarging those pathways and increasing outflow.

Vision test for determining retinal disease progression

The present invention provides a reading test to measure vision loss. In one embodiment, the vision loss is due to disease progression. The tests are useful in evaluating the effects of intervention in vision deterioration. The tests are non-invasive, simple, quick, sensitive, reproducible, and easy to administer. The tests measure the subject's reading speed and accuracy under defined conditions of illumination and contrast. The results of these tests may be used to determine if treatment of a disease should be initiated, terminated, altered, or remain unchanged.

System, method, and non-transitory computer-readable storage media related to correction of vision defects using a visual display

A method of at-home monitoring of eye conditions using a head mounted display that is capable of establishing a visual model associated with a patient. The visual model may include data related to a quality of the patient's vision. The patient may use the system to establish a visual model periodically, such as daily, and the system may compare the visual model to previous visual models and send an alert to the patient's physician if changes meeting a given criteria are detected. This may allow the physician to immediately take steps to save the patient's eyesight where a delay in treatment may result in vision loss.
