Wouldn't it be cool if we had the original announcement from 1750 that Jacques Daviel had revolutionized eye surgery by extracting cataracts, instead of the old method of pushing them into the back of the eye? Oh, wait--the notice was just discovered! researchgate.net/publication/40…

Analysis of 3500 cases from the literature: for small-angle esotropia, do large one-muscle surgery rather than small doses of two-muscle surgery: medrxiv.org/content/10.110…

Read full paper here: Surgery for Esotropia: The "Legend" of the Dose-Response Curve Revisited and the Optimal Surgical Strategy researchgate.net/publication/39…

Optimal surgical strategy is to do a big surgery on minimum number of muscles. If surgical approach is insufficient, add a muscle. This is approach of Scobee (1951) rather than that of Parks (1975), who performed small recessions on 2 muscles for small deviations.

Surgery for Esotropia: The "Legend" of the Dose-Response Curve Revisited and the Optimal Surgical Strategy. Better to do big dose on each muscle (like Scobee in 1951) than to do graded dose (like Parks 1975). For big deviations, operate on more muscles. researchgate.net/publication/39…
