Purpose:
The purpose of this study was to evaluate the clinical and physiological findings and to determine the most appropriate surgical procedure for acquired progressive esotropia with severe myopia.
Methods:
Thirty-eight cases of acquired progressive esotropia with severe myopia were examined to evaluate their clinical and physiological findings. All cases were divided into four groups according to the limitation of their abduction. The eyeball in group IV is fixed in an extremely adducting position. Thirty-one cases underwent strabismus surgery; medial rectus muscle recession and lateral rectus muscle resection in 23 cases, transposition of superior and inferior rectus muscles (modified Jensen procedure included) in eight cases.
Results:
The medial rectus muscle recession with the lateral rectus muscle resection procedure was effective in the early stage of acquired progressive esotropia patients. Transposition procedure was effective in the severe abducting limited patients.
Conclusions:
As the recession & resection procedure is easier than the transposition procedure, we recommend performing surgery in the earlier stage of the abducting disorder before the eyeball is fixed in an extremely adducting position.
