Neuro-Eye Therapy is designed for those who are suffering from vision loss following a head injury or stroke, for example:
- Hemianopia- decreased or lost vision on one half of the visual field
- Quadrantanopia- decreased or lost vision in one quarter of the visual field.
- Scotoma- an area of diminished vision within the visual field.
During a patient’s NeET therapy sessions they will sit in front of a laptop with their head in a chinrest and respond to the images that appear on the computer screen.
The program is customised for the patient and at first the images will appear in the border between the damaged and undamaged parts of their vision. The program responds automatically as the patient’s visual sensitivity increases. Over time as the patient progresses, the images may appear deeper within their damaged field of vision. Each session takes about 25 minutes to complete and we recommend one or two sessions a day, for a minimum of five days per week.
Assessing Eligibility for NeET
NovaVision Sight Science assesses eligibility from visual field tests, together with a review of certain addition information requested from the patient. We ask the patient to obtain the following tests from their optician, ophthalmologist or optometrist:
- Monocular visual fields for the central 30° (preferably using a Humphrey Field Analyser, 30-2 program).
- A binocular Esterman Test.
This information is also required to enable customisation of the program should therapy be appropriate.
Patient Start-Up Process
Please refer to the eligibility requirements, contraindications, warnings and risks provided below before considering if a patient is suitable for NeET.
Once the visual test information is complete the patient should contact NovaVision Sight Science Patient Services.
During the registration process, NovaVision Sight Science will verify the patient’s candidacy and once complete including payment, will send the patient a chinrest and activate their therapy license. Guides will be provided to help the patient download, set up and start their therapy. The patient will then complete a series of tests to evaluate their vision deficit. NovaVision Sight Science then analyses the test results to create and send the patient a customised therapy program.
During the registration process, NovaVision Sight Science will verify the patient’s candidacy and once complete including payment will send the patient a chinrest and a laptop with the therapy installed and customised for their deficit based on their visual field test. Guides will be provided to help the patient set up and start the therapy.
The patient should then begin their twice-daily therapy regimen as soon as possible. The therapy adapts to the patient’s progress and will be updated regularly by Patient Services based on the patient’s deficit and progress with the treatment. During the course of the therapy, the physician can be provided with the patient’s regular results reports and can meet with the patient at any time to evaluate progress.
Contraindications, Warnings And Precautions
Patients with the following medical or physical conditions must not undergo NeET therapy:
History of seizure disorders, especially those of a photosensitive nature. In patients with uncontrolled photosensitive seizure disorders, NeET may have adverse effects including, but not limited to, seizures.
Severe cognitive defects, particularly due to the requirement to be able concentrate for two sessions of 15-25 minutes a day, five days a week.
- Patients with active acute inflammatory diseases of the eyes or central nervous system should not initiate NeET until the acute phase has subsided.
- NeET will not be effective for patients without any residual vision whatsoever (i.e., total cortical blindness).
- NeET treatment requires patients to be seated for extended periods of time. If the patient has been previously diagnosed with deep vein thrombosis (DVT) or has been identified by their physician as having an increased risk of experiencing DVT, the patient should first consult with their physician before initiating NeET treatment.
The following conditions are not treatable by NeET, may impact the ability of a patient to carry out NeET and/or may reduce its effectiveness:
- Uncorrected vision defects such as myopia, hyperopia, astigmatism, presbyopia or tropia (strabismus).
- Progressive disorders such as glaucoma, multiple sclerosis, diabetic retinopathy or macular degeneration.
- Although there are no age limits for the therapy, NeET is not recommended for children, due to the requirement to be able concentrate for two sessions of 15-25 minutes a day, five days a week.
Risks, Dosage & Follow-Up
In common with all activities requiring extended use of a computer screen, NeET 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 perform one session, once or twice daily, five days a week for six months.
Therapy Reports will be provided to the patient’s doctor if wished. Follow-up visits can be conducted to review patient’s progress and determine additional therapy, at the physician’s and patient’s discretion.
