It has been my experience as well as that of other authors^2-4 that esotropic patients with NRC fusion, even bifoveal fusion (40 seconds of arc stereoacuity), can manifest a substantial angle buildup with prisms. Most, if not all, of these patients do benefit when undergoing surgery for the built-up angle.⁴ If this group of patients had been included, a larger percentage of esotropic patients would have been found to benefit from presurgical prism adaptation test (PAT).
