    optician in visual perceptual research and development.<br>will happily supply reading material FOC
  1. A simple guide to vision therapy / colour Vision therapy is based on the premise that milestones have not been achieved and that by using exercises and prisms it is possible to retune the system. It does work in many cases - BUT - it is not suitable in many cases of ASD. It requires daily exercises and may be unpleasant. It also can prove to be very expensive as many professional appointments are necessary - bank on £1000 - £2000 There are three types of tinting assessments available - trial and error eg Irlen, subtractive colour eg the intuitive colorimeter, additive colour eg the Orthoscopics system There is a big difference between these methods - and to give you an idea what government review considers the difference - we were given two awards for improvement of technoque - citing the previous methods as essentially obsolete. The range (gamut) of the colorimeter is small - less than half that of the Orthoscopics instrument - and trial and error is very unlikely to get the right answer - the mathematics of when ambient lighting is changed is extremely complex. In addition the Orthoscopics system can achieve many effects which would be impossible using the other systems - so, caveat emptor.
  2. you should come to our practice in ayr - you may get some answers


  3. it is much better to get problem treated than play games
  4. Sensory processsing problems often are causative (at least in part) of anxiety and many of the mental health problems difficulties experienced in ASD. For example - if the trigger threshold for visual processing problems is exceeeded symptoms can be extreme - and extremely difficult to cope with. A reasonable response is to panic / take whatever action is necessary to escape - and this can be misconstrued as a mental health disorder / meltdown. I would compare it to being in a very noisy / strobing / dizzy and touch / temperature disturbed environment - it is no wonder that children respond in the way that they do. When faces morph and disappear, when the visual field breaks up, when illusions occur, when time and space become distorted - it is vital for some to have their problems addressed.
  5. Sounds as though he has a visual processing disorder - if he has - his actions are understandable - and it is essential that they are addressed if you want to sort out his anxiety / behaviour. Please get it checked
  6. There are a number of opticians using advanced assessment techniques - Jo ONeill at Norvilles opticians in Gloucester is excellent and I would recommend her without reservation. I think she may spend some time at Cirencester too. I do appreciate that parents can have some difficulty who to go to. The differnce between knowledgeable people varies and it virtually impossible for parents to tell the differences. So, here are what you need to ask and what you need to get as answers - you don't need to know what the questions mean -but they are all vital in ASD visual assessments and all should be answered How much colour space is covered - they have to know the answer (anything else is unacceptable) - 0ver 60% is OK (we address about 75%) - some systems address less than 25%! - and the effects are relatively poor in comparison - and children with ASD often need more complex assessments Can they address prosopagnosia and metamorphopsia (essentail in ASD) - yes facial recognition problems are critical in ASD Do they address synesthesia - yes Visual systems affect every sensory system - and are affected by every system too. Cross sensory tests are essential Do they address the Pulfrich effect - yes major effects in shop / school meltdowns due to mid line effects Do they address the McGurk effect - yes causes massive communication problems in ASD Do they address dorsal stream problems - yes Dyspraxia / hand eye coordination / movement / gait are affected Do you see the effects during the test - yes Can the practice test non verbal / non cooperative sensory processing by objective methods - yes If a practice can answer these questions - then go to them. If they don't.... caveat emptor
  7. The system we use has been peer reviewed (and the methods we use were considered to be a significant improvement on all other systems - by government scientists)- and is accepted (but relatively few have the equipment - many more want it) - to quote UK professor of optometry appearing on television "it is the best method currently available" Unfortunately it is also much more expensive and requires a much higher knowledge level - we don't just look at reading speed (an awful assessment method) - and it can do everything that other methods can achieve - and then a lot more. So, if you are prepared to accept poor assessment methods then that is your choice. I would not however accept being associated with them and therefore I have disassociated myself in my post. The system we use is being used in clinical areas (asd is just a side effect) - and opinion exists only where mathematics doesn't. The mathematics is clear - so suggesting that it is my opinion instead of fact is incorrect. Your opinion is uninformed - and potentially damaging to those that presume all systems are the same. They are not - and the difference is often massive.
  8. No its not opinion - it is verifiable mathematically - very simply look at the colour gamut of the Chromagen system in comparison with the Orthoscopics system. There is a massive difference and it worries me if people think that all methods are the same. The Chromagen system is very simplistic - and when we got UK government funding for testing development we cited it as essentially obsolete (and that was 10 years ago!). The methods we use are the ONLY accurate methods available in the UK at present, have over double the range of the next best system and can achieve so much more eg we can treat prosopagnosia / metamorphopsia - so important in ASD - every child on the spectrum should be assessed - sadly they continue to suffer. I want to make it clear that I would not use the methods advocated, and that I would not wish to be associated with them - and as someone had put a on a thread with my name on - I think I have a right to distance myself from a technique which I would not under any circumstances use. As for what is being done in research - I am VERY excited at what we are achieving - but we will not be publishing for a while - for commercial reasons. Some of it will be world news - but not in ASD!
  9. I would like to make it clear that we do NOT use the Chromagen system (as used by optician in previous post) and do not intend to use it in the future. There are BIG differnces in what can be achieved with optimum instruments and lenses - particularly in ASD.
  10. You need to see a specialist - there are a few that can deal with this problem easily PM me and I'll sugggest someone - or you could come to scotland if you wish
  11. There are a number of techniques for improving eye movement - it's complex and may be expensive as it may not be covered by the NHS. It should be covered - but often isn't!
  12. still awful diagnostic criteria - and open up to massive levels of misdiagnosis
  13. Have just found it - sorry not replied The condition is related to a reflex response - and treatable by a knowledgeable person. It is not related to drainage, but control of tear production. send me another pm and i will suggest someone that can help in your area
  14. I do a number of free presentations to charities every year (6). Expenses only - and I don't charge these if I do not have to spend a night away! I have 2 left for this year. Saturdays are usually not available (except as keynote lectures), but Sundays possible. I normally want at least 50 people guaranteed (and preferably a lot more), a room that can go to blackout and the room must be quiet. I can bring PA, radio mics, projector etc for a small cost (to cover costs). Minimum lecture time 1hr 30 - if you have seen me you'll understand For keynote lectures etc - PM me For commercial presentations my costs have to cover loss of business at my practice etc - so costs are substantial - and probably not affordable for a small group. I also work as a consultant for a number of multinationals, expert witness etc
