  • I have been working with the Aniseikonia Inspector for several years now. It is a good and user friendly tool for the clinical management of aniseikonia. I also use the program in my BV lectures at the University of Waterloo School of Optometry to give interactive demos. Nothing but positive comments from here. Thanks.

  • The Aniseikonia Inspector is an easy to use tool that has helped me treat a substantial number of symptomatic aniseikonia patients. I have been using it for over a year and I find that it greatly simplifies aniseikonia management. Most patients can be tested with minimum instructions.  Additionally, calculating an iseikonic prescription is made very easy; simply use the "slider bars" to change the lens parameters and demonstrate the resultant iseikonic correction.

  • We successfully assessed aniseikonia with the Aniseikonia Inspector in a
    long-standing antimetrope, to compare aniseikonia with spectacles to her
    newly prescribed contact lens Rx. The aniseikonia decreased from 5% to <1%;
    stereopsis improved; the patient thus far is quite pleased.

  • It is nice to have a clinical tool that easily measures aniseikonia and then helps design the appropriate lens solution.  This is an often overlooked area of concern in practice which deserves our attention.  I highly recommend the 'Aniseikonia Inspector' to any clinician seeking optimum visual results for their patients.  I also commend Optical
    Diagnostics on the prompt and superior customer service.

  • I have just finished download and looking at the movie. WOW! that is most most impressive what you have created here!!!! I commend you again on your grasp of the subject and also on your program writing which is the best I have seen anywhere.
    You have filled a most urgent need for all eye care professionals, especially those with a serious interest in, or who care for patients, with disorders of binocular vision. All such professionals will be greatly aided in the diagnosis and management of aniseikonia by your program. There is to my knowledge nothing like it available anywhere else today. It enables the ordinary practitioner to do everything including correctly prescribing the necessary alterations to lens base curves, thickness etc., to create a true and proper size correcting lens in combination with the patient's refractive Rx.

  • The Aniseikonia Inspector makes calculating and designing iseikonic spectacle prescriptions a breeze. Patients are impressed with the technology that allows the healthcare provider to subjectively and objectively evaluate their complaints. A superficial explanation of the optics involved and how the software impacts decisions about their prescription makes the patient feel they're getting the best state-of-the-art care.

    Iseikonic spectacle design is a adjunct service that can be provided to patients and can be charged for accordingly. This software makes the treatment of naturally aniseikonic patients and post-operative aniseimetropes far less time-consuming and far more accurate than conventional methods. The Aniseikonia Inspector is a complete turnkey package for iseikonic Rx design. It incorporates testing procedures to determine the amount and type of aniseikonia, confirmation testing to verify that an iseikonic Rx is likely to reduce symptomology, and a lens design module complete with transverse sectional graphics depicting lens geometry change corresponding to various design alterations. Automated design and/or computer recommended design parameters are not provided, but the manual "tweaking" method is easy and quick to master. The printed report can be provided to the patient as a prescription or faxed directly to your finishing laboratory for manufacture of the final lens.

    The software pays for itself in ten or fewer patients if the services are charged appropriately. The only drawback is that aniseikonic patients won't be able to find satisfactory spectacle prescription designs anywhere else so you'll probably have to handle larger numbers of specialty spectacle design cases.

Testimonials from patients

 

..., I celebrate the work of someone like Dr. Gerard deWit.  From my standpoint, Dr. deWit has taken the visual distortion resulting from the repair of retinal detachment and done something positive to make vision a more normal experience.  He has done it for me and from internet responses he has done it for others.  

 

It is a great tribute to Dr. deWit that he has successfully taken on this minority cause.  I marvel that the medical profession, from my experience with 6 eye specialists, has no interest in his work.  

 

For the record, I was left with “surface wrinkling retinopathy” from surgery re-attaching the retina in my right eye.   I was dismissed with that eye seeing a smaller image that was slightly rotated in some areas of my field of vision.  Using results from the Aniseikonia Inspector, Dr. deWit has prescribed lenses (distance and reading) for me which have brought my vision, in most areas of my vision field,  back to normal.  For me, it has been a definite “WOW’ event for which I am most grateful.  

 

I recommend him with great enthusiasm.

I developed aniseikonia secondary to an epiretinal membrane (macular pucker). My eyes teared continuously, and I was very sensitive to light. The local doctors I consulted couldn't help me, and I was fortunate to find Dr. de Wit on the internet (I also found an aniseikonia testing service at Ohio State University, but they charged $2,000, with a 2-month wait for an appointment).  The Aniseikonia Inspector program was easy to set up on my home computer, and the test was fun to do. Unlike other tests which give only one measure of the amount of aniseikonia, the Aniseikonia Inspector provided a detailed description of my condition, with multiple measures in different directions and at different visual field angles. Based on this comprehensive output, Dr. de Wit worked with me and my eye care provider to fine-tune the best possible correction. With my new glasses, my eyes finally stopped tearing, and I'm no longer overly sensitive to light.
 

Based on Dr. de Wit's in-depth knowledge of aniseikonia, his state-of-the-art testing methodology, and his prompt and courteous responses to questions, I would enthusiastically recommend his testing service.

I experienced a left-eye macula-off retinal detachment, caused by PVD, not trauma. ...

  

... It wasn’t until I reviewed the helpful resources on Dr. de Wit’s Web site that I could put a name to my visual condition. It was a godsend just to have a name for my visual anomaly!

  

Over the next few weeks, I emailed Dr. de Wit many, many questions and in every case, he replied with highly detailed, timely and understandable responses. He also helped me download, install and use the “Aniseikonia Inspector” software program on my home computer. I ran the tests, using the green/red glasses that I received in the mail from Dr. de Wit.

  

With Dr. de Wit’s help and his Aniseikonia Inspector software, I took the recommended eyeglass prescription to an optometrist. What came back was a new pair of sports sunglasses that corrected for my aniseikonia! The smaller images in my left eye are now magnified, which allows me to have depth perception while running dirt trails during my daily exercise. With these glasses on, I know when my foot and the ground will actually meet. They allow me to see the ground in 3D again!  I couldn’t be happier!

  

Plus I learned a profound lesson: There’s at least ONE PERSON in the entire universe who understands my vision anomaly and how to treat it.  I recommend Dr. de Wit and his services highly!

In 2004 I developed a retinoschisis (splitting of the retina), which totally changed the size perception in that eye. Cars looked all of a sudden very narrow and high. That could be considered funny, but the headaches weren't. More than a year later, I found Gerard de Wit, who was researching retinally-induced aniseikonia. With his software, we were finally able to quantify and understand what was going on. The measured aniseikonia was completely in accordance with my own observations and the data was very helpful in the communication with the ophthalmologists. Unfortunately, the aniseikonia was so a-typical that optical correction was impossible. Nevertheless, I am very glad to have found Gerard's superb aniseikonia testing service. He has always been very fast with responding to my inquiries, made me understand what was going on, and some of his hints actually helped me cope better with the aniseikonia.
 

Based on the published scientific research, Gerard also seems to be the only person in the world who is really trying to understand better and solve retinally-induced aniseikonia problems. With his aniseikonia testing and optical correction calculation software in place, I think the next step is to integrate the aniseikonia data with other ophthalmic visualization techniques such as OCT scans. This could help the ophthalmologist to better understand the experienced visual changes in relation to the changed pathology. I will continue to follow his research efforts and fully recommend his aniseikonia testing service.

... I spent a lot of time visiting optometrists, doctors, even psychiatrists trying to get help. Eventually Moorfields gave me an occlusion patch for the right eye.
 
Eventually I discovered that I was suffering from aniseikonia, and this led me, via the internet, to Gerard De Wit's web site 'opticaldiagnostics.com'. Although I did not meet Gerard at that time, I purchased his software and was able, successfully and quite easily, to run the tests for aniseikonia on my laptop. Gerard provided a glasses prescription which Boots the Chemists then dispensed.  I went back to Moorfields and they accepted that the glasses were indeed helpful in partially rectifying the image disparity. 
 
Now that I am developing a cataract in my right eye Moorfields have said that they will consult Gerard when it comes calculating the specifications for the intra-occular lens. I know of no other source of expertise which could have helped my vision in the way that Gerard has. All my efforts to track down his type of in-depth knowledge have only reinforced my belief that aniseikonia is a little-researched condition.

...    During the past 20 years I have seen four ophthalmologists and two optometrists.  All were aware of my aniseikonia and tried to address it, but none had any way to measure it quantitatively or test it qualitatively (e.g., with "size" lenses).
   
...    the detailed Aniseikonia Inspector graphic results showing magnification distortion versus field angle for the first time gives me a quantitative description of my problem  With that I can discuss options with my ophthalmologist and optometrist at my next annual exam that they otherwise have no facility to measure.
 
...    My experience with Dr. De Wit has been very useful, and enlightening, and Dr. De Wit has been very courteous and responsive to every inquiry.  With Aniseikonia Inspector test results I have a thoroughly objective, detailed description of my aniseikonia.  I know of no other way I could get these results.  Moreover, Dr. De Wit's interaction has given me confidence in understanding it.

...    When I discussed the difference in image size, my ophthalmologist named the symptom “aniseikonia” but had no suggested response.  

  

I researched the issue on the internet, and came upon the Aniseikonia Inspector, and corresponded with its creator, Gerard de Wit.  He sent increasingly improved versions of the software, which I used to verify and quantify my aniseikonia and, eventually to give my ophthalmologist specifications for corrective lenses. She and Gerard collaborated, she used a version of the program, had her optician spouse grind some test lenses to test the available degree of magnification, and with those I was able to determine the optimum correction available with glass lenses (I have rejected contacts, which might achieve a higher degree of correction, and I’m hopeless with plastic lenses).

  

The result was a pair of glasses that substantially diminishes the disparity in image size and achieves a fully acceptable reading and viewing comfort at work and otherwise. Gerard's service and the Aniseikonia Inspector provided me and my ophthalmologist a solution to my vision problem that as far as I can tell was largely unknown in the field, and I am grateful for the improvement.
