Vision improvement in AMD
Case Report: 83-year-old woman with AMD treated with RevitalVision
83-year-old woman, blind in her left eye due to thrombosis at age 6, and with 30° prism exotropia.
Right eye with dry stage of Age related Macular Degeneration (AMD) for the past 20 years and with early stage of cataract.
Right – 6/30 (20/200).
Left – LP (Light Perception)
Subjective refraction: Right +1.50/ -1.25 x 101
Examined and followed up by Opt. MSc. Eyal Berko from Dr. Optica, Givatayim, Israel.
Macular degeneration - treatment process:
A company representative helped the patient (by phone) to install RV software on her PC, and followed up with 40 minutes of a remote guided training session. It should be noted that the patient had no early experience using a PC at all.
The patient began with 3-4 training sessions per week, each session lasting approximately 30 minutes.
The patient returned to the same clinic for a follow-up VA exam after 20, 40 and 60 sessions.
After 20 sessions:
BCVA – 6/20 (20/63)
After 40 sessions:
BCVA – 6/15 (20/50)
After 60 sessions:
BCVA – 6/20 (20/40)
The patient improved 4 lines on the VA test chart and reported on subjective vision improvement in her daily activity.
This interesting case report, demonstrating extraordinary vision improvement in a 83 year old patient suffering from AMD, joins dozens of other reports, received from different clinics around the world indicating significant improvement in most patients suffering from retinal diseases (AMD, Congenital MD, Stargardt, RP), as well as other eye diseases.
How can RevitalVision improve vision in AMD Patient?
RevitalVision is clinically proven (with controlled randomized studies) to improve vision in adult amblyopia, and has received FDA approval for this treatment indication. Later, controlled randomized trials proved its efficacy in improving uncorrected vision in patients with minor refractive error, enabling the brain to better process blurred images into sharper ones. In other words, improved image processing can compensate to an extent for a blurred image, transferred from the retina.
The treatment exploits residual neuroplasticity existing in adults, and through repetitive performance of controlled patient specific visual tasks, creates a perceptual learning process.
It is possible that lack of prolonged effective cortical stimulation, caused by a blurred or damaged image transferred from the retina to the brain, results in reduced cortical activity.
Thus, in addition to the anatomical damage to the eye, there is secondary gradually -evolved damage to the quality of the image processing in the brain.
Similar to amblyopia, effective stimulation and perceptual learning process enables significant improvement in cortical activity, resulting in improved visual acuity and contrast sensitivity, despite the absence of any anatomical improvement or changes during the course of the disease.
We hope that future controlled randomized studies will replicate these encouraging reports, and may provide answers to our question.
