PURPOSE: To explore the application of preoperative fusional convergence amplitudes in the selection of a target angle for non-adjustable suture strabismus surgery with deteriorated intermittent esotropia and diplopia.
METHODS: Thirty-one consecutive cases of presumed acquired non-accommodative, deteriorated intermittent esotropia managed surgically between 2005 and 2016 were reviewed retrospectively. For each individual, a target angle (deviation angle for which surgery was based) was selected preoperatively after analysis of fusional convergence amplitudes. Outcomes in patients selected for overcorrection at 6 meters (target angle > angle in primary position at 6 meters) were compared to those who had planned surgery based on a target angle that did not exceed their measured angle (target angle ≤ angle in primary position) at 6 meters.
RESULTS: All 31 patients achieved binocular single vision in primary position at both near and 6 meters without prisms, orthoptic therapy, or additional surgery at 4 to 6 months postoperatively. Greater mean correction in the target angle > angle in primary position group compared to the target angle ≤ angle in primary position group was observed, but this difference was not statistically significant (P = .57).
CONCLUSIONS: Among this diagnostically specific cohort with intermittent esotropia with symptomatic diplopia and measurable binocular single vision preoperatively, targeted surgery based on an analysis of preexisting fusional convergence amplitudes had an outcome that compared favorably to that of documented adjustable suture strabismus surgery.
