This patient has an exophoria and a V exo pattern. Alternating cover test with glasses in place reveals an exophoria that increases in size to approximately 10Δ with good recovery. The exophoria increases in size to 20Δ on elevation and decreases to 2Δ on depression. There has to be a difference of at least 15Δ between the size of the exophoria in elevation and the size in depression before the diagnosis of a V exo pattern can be made. Normally the base of the occluder would be juxtaposed against the patient’s cheeks when assessing the deviation in down gaze, but this was not possible in this case for filming reasons.
