Risks, Dosage & Follow-Up
In common with all activities requiring extended use of a computer screen, NovaVision VRT may cause light headaches or fatigue if performed too intensively or without sufficient relaxation periods (breaks). If this occurs, patients should take more frequent breaks during the session or request shortened therapy times. If this persists, patients should temporarily discontinue the therapy until symptoms subside and notify their healthcare professional.
It is recommended that a patient receive a prescription for one session twice daily, six days a week for six months.
Contact information for NovaVision Patient Services should accompany the VRT prescription since the prescription can only be filled by NovaVision. The prescription, visual field test results, eye exam report, and payment arrangement will be required before commencement of treatment.
Therapy Reports can be provided to the patient’s prescribing doctor. Follow-up visits can be conducted to review patient’s progress and determine additional therapy, at the physician’s discretion.
