Stability of the Functional Cure in Congenital Esotropia
Purpose:
To report the stability of the functional cure in a chart review of patients with congenital esotropia.
Methods:
The charts of 31 patients with congenital esotropia, encountered in 2007-2012 with functional cure, were studied. The stability of the cure and duration of follow-up were determined by comparing the first recorded date of cure with the date of the last examination. The mean age of the patients analyzed was 19.5 years.
Results:
Two patients decompensated in the subgroup of 24 patients who did not require hyperopic correction and 1 patient decompensated in the subgroup of 7 patients who required hyperopic correction. All patients with decompensation were realigned by secondary surgery. A small subgroup of 4 patients demonstrated gradual improvement of stereoacuity to 60 arc seconds or better.
Conclusions:
The functional cure of congenital esotropia is relatively stable in patients within the first 20 years. The secondary use of hyperopic correction and secondary surgery increased this stability.

Stability of Equilibrium Configuration
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
