PSYCHOPHYSICAL EVALUATION OF THE EFFECT OF VITREOUS FLOATERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240016379 titled 'PSYCHOPHYSICAL EVALUATION OF THE EFFECT OF VITREOUS FLOATERS
Simplified Explanation
The disclosed embodiments enable the evaluation of vitreous floaters through psychophysical methods. This involves projecting stimulus images onto the patient's retina, capturing images of the patient's retina using an SLO, and deriving shadow images from these captured images. The shadow images represent the shadows cast by floaters. Observer stimulus images are generated from the shadow images and patient stimulus images, and these images are projected onto the retinas of an observer using a virtual reality display device.
- The patent enables the evaluation of vitreous floaters through psychophysical methods.
- Patient stimulus images are projected onto the patient's retina, including a fixation target.
- Images of the patient's retina are captured using an SLO.
- Shadow images are derived from the captured images, representing the shadows cast by floaters.
- Observer stimulus images are generated from the shadow images and patient stimulus images.
- The observer stimulus images are projected onto the retinas of an observer using a virtual reality display device.
Potential Applications:
- Medical diagnosis and evaluation of vitreous floaters.
- Research and development of treatments for vitreous floaters.
- Training and education in ophthalmology and optometry.
Problems Solved:
- Provides a non-invasive method for evaluating vitreous floaters.
- Enables the visualization and analysis of floaters and their impact on vision.
- Allows for the assessment of the severity and characteristics of floaters.
Benefits:
- Improved understanding and assessment of vitreous floaters.
- Enhanced diagnosis and treatment planning for patients with floaters.
- Non-invasive and objective evaluation of floaters.
- Potential for advancements in ophthalmic research and education.
Original Abstract Submitted
particular embodiments disclosed herein enable psychophysical evaluation of vitreous floaters. one or more patient stimulus images are projected onto the patient's retina, the patient images including a stationary or mobile fixation target. while the patient stimulus images are displayed, images of the patient's retina are captured, such as using an slo, and shadow images are derived from the images. the shadow images include representations of shadows cast by floaters. observer stimulus images are generated from the shadow images and the patient stimulus images and projected onto the retinas of an observer, such as using a virtual reality display device.
