Purpose: The measurement of outcomes of pediatric therapy will be increasingly important to third-party payers as they allocate health care resources. We undertook this study to assess the effectiveness of treatment of acquired esotropia, as measured subjectively by parents and objectively by examination.
Methods: A chart review was used to gather objective clinical data from all patients presenting between 1994 and 1995 with esotropia after their first birthday. Parents' impressions of the quality and impact of treatment were tabulated by using a telephone questionnaire.
Results: Of 48 patients studied (mean age, 3.8 years; 44 months' follow-up), the 26 with amblyopia were effectively treated in 81% of cases. Mean esotropic angles decreased, with glasses and/or surgery, from 33.1 to 4.9 PD at distance and from 40.0 to 11.4 PD at near. The average estimated cost of care was 547 dollars per patient per year. Parents considered treatment "extremely important" to their child's future happiness and success in 90% of cases.
Conclusion: Our experience has shown that treatment of acquired esotropia in childhood, while relatively inexpensive, is highly effective, both objectively and subjectively.
