Oblique

Exophoria is the tendency of the eye position to deviate outwards. It can usually be controlled by corrective fusion reflection, so that no deflection occurs and the eyes can be maintained monocularly. Generally, if the oblique exceeds 5 △, symptoms may appear. However, it also depends on the patient's fusion function. If anyone sees near 10 △ faint oblique, it is asymptomatic because of good convergence, but on the contrary, someone sees near faint oblique 4 △, which is a normal range, but fusion Poor convergence, but visual fatigue.
