Low Vision/ Eye disease
The program is suitable for people suffering from different eye diseases (such as: retinal, corneal, nystagmus and more…) age 9 and up, with stable vision and with best corrected vision up to 20/200. There is no limitation on refraction. The goal of the program is to enable better vision and visual function despite the eye disease.
Clinical studies and case reports have demonstrated RevitalVision’s efficacy in improving vision in various eye diseases, such as Nystgmus, Stargardt, RP, Karatocunus patients following intrastromal corneal rings and more. Additional studies are done these days in various pathologies. View studies here.
The mechanism underlaying the visual improvement is yet to be investigated. Possible explanation is 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.
Indications for use:
- Patients 9 years or older suffering from an eye disease, effecting the central vision.
Clinical Outcome: (based on current data)
- Improved VA (2 VA lines on average)
- Improved CS (100% on FACT sine wave on average)
Contra Indication:
- Peripheral vison loss (the program improvers central vision only)
- Diplopia
- Brain damage
- Epilepsy
Precautions:
- Unstable vision/ vision fluctuations
- Severe untreated attention disorder
Treatment Criteria:
- BCVA up to 20/200 (6/60)
- Cognitive intact
- Motivated to complete 40 training sessions in a 3-month period
- Sufficient visual field – can see full computer screen from 1 meter
- Successful handle a visual task session (Demo session)
Treatment Protocol:
- Patient has to be best corrected
- 40 – 60 training sessions
- Follow up exam is recommended after 20 and 40 sessions
Clinical Follow Up:
- BCVA distance & near
- Contrast Sensitivity (FACT sine wave test) – recommended
