For me, the Waggoner Computerized Color Vision Test (Waggoner CCVT) has shown to be sensitive and reinforces the diagnosis (and level of severity).  For example, when we look at an AMD patient, and even OCT this patient, all we have is an idea of structure. It doesn’t really tell me what is the function.  

The Diopsys (also functional assessment) so far is running consistent with Waggoner Diagnostics’ color vision test. A patient may “look like” they have a fair amount of AMD in their OD but the Diopsys says the eye is functioning better than I would expect. Lo and behold, when I look at the color vision test, the tritan deficiency is less (or not even deficient) on the OD. 

I had a Plaquenil patient this week. When you see the “flying saucer” on the OCT, we now know that’s a little later than desired. Ideally would like to pick up IS/OS separation, but to me that’s a challenge. I really like having the color vision to say - “all good”.  I’m adding the multifocal ERG soon and that will help a lot with Plaquenil. We now know the deposits do NOT occur first under the fovea. So, getting some parafoveal info from color and MF ERG will be nice. 

The same principle applies to glaucoma (optic neuropathy) and amblyopia. When doing color test monocularly, the results quickly validate the severity of the disease.  

If user has Administrator rights on the Windows operating system, then he/she is able to install the Waggoner CCVT for all users. By default it will install in the following location, "C:\Program Files (x86)\Waggoner\Waggoner CCVT." The Waggoner CCVT will be available for each Windows user registered in system. 

IMPORTANT NOTE: Each Windows user will have their own patient database created for them. This means that User A will only be able to see tests results for tests administered under User A and User B will only be able to see results for the tests that were administered under User B.

Storing approximately 100 test results is equal to approximately 1 megabyte. This means that 100,000 test results can be saved on 1 gigabyte.

1. Check that other applications on your computer have an internet connection. Check at least 3 different programs. Here are some suggestions:

• Open your internet browser (Ex. Google Chrome, Safari, Mozilla Firefox) and navigate to www.WaggonerDiagnostics.com
  
• Open default Windows email client and send test email to support@waggonerdiagnostics.com. Ensure that email sent without errors. Such way you will be sure email gateway works correctly in your system.
  
• Download any well known 3rd party program and check your internet connection with it. If the 3rd party program can connect to the internet, your computer's operating system policies does not allow Internet connections for unknown/new programs.
  

2. Disable Windows Defender Firewall. (https://support.microsoft.com/en-ae/help/4028544/windows-10-turn-windows-defender-firewall-on-or-off)

• Please restart the Waggoner CCVT and check internet connection.
  
• Otherwise, Check Windows Defender Firewall. Details in this article https://www.technipages.com/blockunblock-programs-in-windows-firewall. Make sure that Waggoner WCCVT application is not blocked. If it is, please unblock it. If there is still no connection after unblocking the Waggoner CCVT , please move onto step 3.
  

3. Check proxy settings and troubleshoot internet connection as described here https://answers.microsoft.com/en-us/windows/forum/windows_7-networking/programs-cant-connect-to-the-internet/0ce72c11-58ae-4a15-9a01-b45af758eefd

4. Turn off your third-party Antivirus and/or Firewall and then check the  internet connection on the Waggoner CCVT.

• If a third-party Antivirus is a reason then google "unblock program <your antivirus name>" for instructions of how to unblock Waggoner WCCVT in your Antivirus. For example "unblock program avast"
  

5. If possible, create new user in the Windows operating system and install Waggoner WCCVT for new user.

• If possible, switch to administrator account and install/run Waggoner WCCVT from that account. (https://www.google.com/search?q=how+to+create+new+user+in+windows&ie=utf-8&oe=utf-8&aq=t) 
  
• Run Waggoner WCCVT with admin rights by right click on icon and choose 'Run as Administrator' from popup menu.  
  

6. If none of the above worked, please contact your system administrator if you have one available and ask for assistance.

7. If none of the above worked, please contact your Internet Service Provider support

8. If none of the above worked, there's a possibility your system was infected with malware that prevents connection to the internet for other programs. We recommend doing a full system scan with your installed Antivirus.

• We recommend downloading and use Malwarebytes anti-malware and Super AntiSpyware and let the application scan your operating system.
  

• Microsoft Windows 7 SP1 or above operating system.

Color vision testing is performed by eye care professionals to identify both genetic and acquired color vision deficiencies within their patients. Genetic deficiencies affect 8% of men and .5% of women. Acquired deficiencies affect up to 15% of the general population and help in identifying diseases such as glaucoma, multiple sclerosis, diabetes, macular degeneration, and optic neuropathies. Acquired deficiencies can also be caused by 300+ substances at toxic levels such as Plaquenil.

Waggoner Diagnostics asked its doctors this exact question. I think the best answer we received was from Dr. Lee Ford in Mississippi. Dr. Ford says he screens every single person, every visit because "if you aren't looking, you won't find anything."

It's difficult for us to provide a one size fits all answer for this because each practice is different. However, many doctors that we talk with suggest giving the Waggoner CCVT in the pre-screening room with under their technicians supervision. This then allows the doctor to come and and immediately look at whether the patient has a genetic or acquired color vision deficiency. 

We would not recommend giving it at the end of the exam because the Waggoner CCVT raises the red flag for the eye care professional regarding disease and toxic levels of substances. 

For the initial visit, we recommend using the Adult/Senior/Older Children Diagnostic to provide an in-depth look at both genetic and acquired deficiencies. We recommend testing each patient, every visit using the acquired test (12-plate Tritan) after the initial visit to help with identifying diseases such as glaucoma, multiple sclerosis, macular degeneration, and optic neuropathies. 

This exact value of reimbursement fluctuates from state to state and town to town. Here is our FAQ regarding CPT 92283 and a list of ICD-10 codes. As it currently stands as of January 29th, 2019, the national average for reimbursement under CPT 92283 is $55 national average.

CPT 92283 is used for extended color vision testing. Please find a CPT 92283 FAQ here.

Due to the restraints that Apple puts on its developers, there are a few differences between the iPad and the Windows version of the Waggoner CCVT. To begin, from a screening and diagnostic perspective, the Waggoner CCVT on iPad receives the same results as our Windows version. All differences explained below are in regards to functionality and NOT validity and reliability of the Waggoner CCVT results. Here are the current differences but it may not be exhaustive list:

• Can't save results as PDF. The results are saved to the camera roll of the iPad and can be viewed at any time for your convenience. Several doctors have implemented the iPad into their practice and are able to get the results from their iPad to their EMR. Due to every doctor's office IT being setup differently, we recommend contacting your IT team on the best way to integrate saving the results from your iPad to your EMR.

• There are no color or luminance calibration screens because iPads have an excellent rendition of color according to research completed by the U.S. Navy. With that said, we recommend going into the settings section and placing the iPad's luminance (brightness) to 50% of its maximum ability (approximately 100 candela/m2). In addition, you will want to disable "True Tone." Here are instructions from Apple.

• Printing from an iPad requires a AirPrint capable printer. Plus, when printed, the results screen does not take up the entire page like the Windows version. It is scaled down for some reason. We do believe that this can be fixed and will explore this when updating to new versions.

• Unfortunately, at this time, we do not have the ability to have a 30-day trial with the iPad version of the Waggoner CCVT. We also plan on changing this during the next update.

Apple uses a technology called AirPrint and you must have a printer that is AirPrint compatible. The Waggoner CCVT for iPad works well with AirPrint but you must ensure that your printer is setup with your iPad. Here is a video from Apple to help better understand AirPrint: https://www.youtube.com/watch?v=UxJrQJmB6UA

- iPad 2 (released march 2011) and any model released afterward.
- iOS 8 or later.
