The College of Optometrists

(1)In the BV station can you ask the patient questions about Orthopic treatment, diplopia, general health etc?

(2) When doing ocular motility should you do cover test in all directions of gaze?

(3) If heterotropia is seen do you still measure NPC?

(4) Apart from pen to nose exercises, How do you instruct a patient to use dot stereograms and how else do you increase positive fusional reserves?

Thanks

1) yes -unless an examiner says othwise 2) yes - and on motility go right out as far as you can 3) why not? Unless the squint precludes it 4) you could try diplopia exercises with two pencils - or bar reading at different distances

hi,

i just wanted to ask a quick questioon regarding the bv station. Normally when i do motility and am checking any underactions, i just do an alternating cover test in each position of gaze (if im doing it purely objectively - without asking any questions). I go as far out as i can in motility, do the alternating cover test, and the eye that makes the most movement in the positon of gaze which my pentorch is in, is the one which is underacting? is this correct, iv done it for so long, without thinking about it, that im now having doubts.

also is it posible to check overactions usiong this method?

I suppose to some extent you can -trying to look at the bigger picture helps:

I mean they look left and you notice a movement on covertest in the left eye - suspected left lateral weakness or check ligament.

but it does not preclude something wrong in RE muscles.

I tend to do my motility simply noting whats going on - and have a look at my notes at the end of it. I tend to draw the findings -
