NovaVision VRT® Device
NovaVision’s FDA-Cleared VRT device provides customized therapy
to patients with vision loss as a result of stroke or traumatic brain injury.
The VRT device is leased to the patient by NovaVision, and is sent to the
patient’s residence. Upon receipt, the patient performs a self-guided
diagnostic that maps the visual field deficit so the therapy can be created for
optimal results. This test uses high
resolution perimetry and is also used to evaluate the visual deficit after each
month of therapy. Between monthly
testing, the device delivers twice-daily therapy sessions six days per week.
While there is some variation each month, both the therapy and testing involve
focusing on a point near the center of the screen and responding to light
stimuli that appear. The device requires either VOIP, DSL or analog phone
connection and users do not need previous computer experience.

NovaVision
HMP™ Device
New
in Q4 of 2009, the NovaVision HMP™Head-Mounted Perimeter is a portable visual
field screening device that increases accessibility to basic visual field
testing for both mainstream patients as well as those with physical limitations
that might make standard visual field testing impossible.
- Patient hardware: During testing, the patient wears a head-mounted
display and uses a simple response button designed to accommodate a wide
variety of physical and cognitive ability levels to respond to light stimuli.
- Examiner hardware: The examiner uses
an intuitive, easy-to-read touch screen display to enter patient data into the
robust processor which stores and transfers data to an office network or flash
drive. All components fit within a 22” x16.5”x7”carrying case convenient for
travel between offices or exam rooms, within nursing homes or remote areas. It
runs on AC power, or a rechargeable battery may also be purchased.
- Testing design: The device tests a
visual field of 60° x 44º in under 5 minutes per eye utilizing a 3-zone
suprathreshold screening strategy common in standard perimetry
and as referenced in CPT code 92082. The test uses 7 brightness levels. If a
light stimulus in a location is missed, the area is retested up to two more
times, ultimately at the brightest level should the second attempt be missed.
- Reporting: The comprehensive
report not only reproduces the graphical display and key metrics shown during
testing but provides information on what tasks were performed, the time
duration of these events and whether they were completed.
Early
users* have been excited by how easy the device is to use as well as the
increased sensitivity of the results. Michael
Mandese, OD FAOS, stated, “I recommend the HMP because it is simple to
administer, comfortable for my patients, and most importantly because it offers
increased sensitivity by testing every 4 degrees vs every 6 degrees. The HMP
has picked up deficits that other screening devices have missed.” Patients* have also reported preference for visual field testing
with the HMP. A young man with short periods of
blindness from MS who has performed visual field testing 16 times volunteered that
he preferred the HMP for the comfort, clarity and darkness of the screen and
the ability to easily put the device over his own glasses. He also found it
less disorienting as he could see the room in his peripheral vision.
NovaVision
Inpatient™ Device
The NovaVision Inpatient™ Device is designed to be
administered at rehab centers and hospitals as part of a comprehensive
inpatient program to help stroke and TBI patients potentially regain some of
their lost vision. The device enables rehabilitation and clinical teams to perform
high resolution perimetry visual field diagnostic tests to screen for central
visual field deficits commonly associated with stroke or brain injury in less
than 10 minutes and begin Vision Restoration Therapy (VRT) while the patient is
still under the hospital’s care. Because
an undetected visual field deficit may adversely impact other rehabilitation
modalities, early detection and treatment of a visual field deficit are critical steps towards improving overall
patient care. Additionally, studies have
shown that early intervention can work as a primer to improve long-term
therapeutic results1.
The inpatient vision restoration therapy sessions are
typically 15 minutes twice daily and session results may be printed upon
completion for review. Upon discharge from the facility, the patient may
continue with VRT as an outpaitnet or receive a prescription to lease a medical
device from NovaVision to continue VRT at home.
An Inpatient Center may receive the following:
- FDA-Cleared Medical Device and Chinrest
- Multi-user software with unlimited use license
- Ergonomic Movable Workstation (Optional)
- Additional Laptop for Technician
- Patient Tracking Program for Administrators
Four key elements of the VRT Inpatient process:
- Diagnostic Testing: Enter patient information
and conduct testing. Save test results and print
report to add to the patient’s file.
- Therapy: If a visual field
deficit is present, select an appropriate program based on the location of the
patient’s deficit and other needs. Adjustable sessions provide
shorter customizable 3-10 minute sessions; appropriate for patients who need
more time to respond or higher color contrast.
Schedule the patient for
twice-daily therapy sessions. Print therapy session
reports as needed.
- Diagnostic Testing: Before
discharge, run a final test and evaluate the patient for possible continuation
at home.
- Prescription: Complete the
prescription form for appropriate patients and send to NovaVision.
