In cases of incomitant strabismus it has been traditional where there is a possibility of a restrictive problem to carry out a traction test and further investigations have commonly included a CT scan. We are now routinely using MRI scanning to investigate disease of the extraocular muscles and we have found it useful to develop a technique of cine magnetic resonance imaging whereby multiple sequential static orbital MRI films are taken in different positions of gaze. These images are then viewed in rapid sequence to give the illusion of movement of the eyes. The high quality soft tissue differentiation of magnetic resonance imaging (MRI) when viewed in rapid sequence allows good assessment of eye muscle contractility. We have applied this technique in a range of patients and found it to be very useful in certain cases ( 1 ).
