Video update – Vitreous imaging in a person complaining of floaters.
The VDM Project has defined as one of its first goals the development of better and more informative IMAGING so as to enable new treatment options. In order to adequately evaluate vitreous structure and correctly diagnose Vision Degrading Myodesopsia (VDM), and to test the success of future treatments and trials, we need new and better technologies to image human vitreous.
In this video, Professor Sebag discusses the images obtained using an optical imaging technology called Optical Coherence Tomography, or OCT. With this technology you can clearly see in 3D the opacities within the vitreous body that interfere with the passage of light from the front of the eye (at top of scan) to the inside of the back of the eye (bottom of scan), casting shadows that are perceived as “floaters”..
Professor Sebag explains the basic anatomy / structure of the eye, and then clarifies the benefits of this new technology and others, such as ultrasound, that can be used to image the vitreous body.
He explains that in addition to these qualitative images, there is a need to accurately quantify vitreous opacities in the eye (detailing their number, size and distribution), to effectively diagnose the patient. With these tools in place, eye doctors will be able to identify cases in which the patient’s condition can be diagnosed as Vision Degrading Myodesopsia (VDM), which are the cases that merit treatment.
The video is just 5 minutes – it is a good introduction to the field of vitreous imaging and we hope that, with your support, we will have more updates to share in the future regarding the progress of imaging research teams working with the VDM Project.
