Binocular Vision – Easier Than You Think (Lecture)

This one hour lecture, delivered to final year QUT optometry students, describes a simplified two-system approach to BV diagnosis and management, with cases, then details easy use of prism correction for vergence disorders; changes to BV in contact lens wear; and why BV matters - for reading and learning in kids, clinical problem solving, and myopia management. By far the most popular of Myopia Profile's Youtube videos!

For more on this topic, you can read four reasons why binocular vision matters in myopia management, and head to the Expand your clinical skills portal to learn more about binocular vision and myopia.

  1. Hi Kate. I enjoyed listening to this lecture. Could you please clarify a couple of points for me: 1.) For the final rx you prescribed TC (the 9 year old boy at 29min:56sec) was this given as single vision near glasses and he would be advised to take them off when reading at distance, such as looking at the board at school? 2.) At 38min:18sec you said if you neutralise with -1.00 then they’re rx is -0.50. Shouldn’t the rx be -2.50 if you are neutralising with a -1.00 flipper only (no working distance lens)? Thanks

    • Hi Kieran, thanks for watching! The final Rx for TC is described in the next slide – he was prescribed an extended focus lens so he could wear this correction full time in class, and for near work at home. Prescribing single vision near in younger children presents a real compliance challenge – progressive or extended focus lenses work much better. To your second point – I’ve slipped up in the video and you’re correct – I should have said +1.00 not -1.00. So neutralisation with +1.00 flippers = -0.50 retinoscopy result, and as you’ve said, neutralisation with -1.00 flippers = -2.50 result.
