Why is squint surgery in children in decline?

Abstract

/aims: Paediatric squint surgery appears to be declining. This study aims to identify if this is so and, if so, why. Retrospective review of (1) episodes of paediatric squint surgery in Scotland and Tayside, 1986-2001, (2) presentations to orthoptists (Tayside) during 1986 and 1996. (1) Overall, a 58% fall in surgery in Scotland and 59% in Tayside. For esotropia, a reduction of 63% (Scotland) and 69% (Tayside). (2) Incidence of esotropia was unchanged; surgery for these esotropes fell (from 55% to 30%) (p = 0.013). More children received maximum hypermetropic correction (p <0.001) and more developed stereopsis (p = 0.003). Childhood strabismus surgery, particularly for esotropia, is declining. The maximum hypermetropic correction has improved the functional results.
