Based on analyses in a series of 116 patients, we found that the response
to strabismus surgery (degrees of change of ocular alignment per millimeter
of rectus recession) correlated significantly with the preoperative
deviation for esotropic and exotropic patients. The prediction of response
to strabismus surgery was not improved significantly with the inclusion of
axial length, age, and/or preoperative refractive error beyond the
prediction provided with use of only the preoperative deviation, even
though we have previously suggested that the response to strabismus surgery
should be related to axial length. We believed that larger eyes should have
a smaller response for the same number of millimeters of surgery than
smaller eyes. We now believe that although the response to strabismus
surgery does correlate significantly and inversely with axial length, this
correlation may not be clinically important given the much stronger
influence of preoperative deviation.
