title: [Amblyopia, refractive errors and strabismus in congenital ptosis].
abstract: The incidence of amblyopia in the normal population is 2-6%, whereas among patients with congenital ptosis it can be as high as 50%. We reviewed 146 cases of congenital ptosis in patients aged between 5 months and 15 years and compared them to a control group of 34 age- and sex-matched patients. In 78 children (156 eyes) reliable optotype visual acuity could be obtained. Fifty-three eyes (34%) were amblyopic. Ametropia was responsible for 34% and anisometropia for 28.3% of the amblyopia cases. In 25.4% of cases strabismus, and in 11.34% stimulus deprivation, was the reason for the development of amblyopia. Children with congenital ptosis should have retinoscopy done in cycloplegia, and refractive errors should be corrected early. Controlled patching therapy should also be started early. Since stimulus deprivation amblyopia is rare, congenital ptosis need not be corrected early in life.
