Ophthalmological follow-up at 2 years of age of all children previously screened for retinopathy of prematurity: is it worthwhile?

Abstract

Purpose: To evaluate the extent to which ophthalmological follow-up at 2 years of age of children born before 32 weeks gestation identifies obvious visual problems, strabismus and significant ametropia (target conditions).

Methods: Of 172 children born during a period of 2.5 years from January 2000, 142 underwent an ophthalmological examination at a median age of 2.33 years. This included evaluation of visual behaviour, cover testing and autorefractometry in cycloplegia. For children with the target conditions, we investigated whether the child had been followed in the eye clinic or referred before 2 years of age, or whether the abnormality was detected as a result of the follow-up examination.

Results: None of the target conditions were found in 117 children. None of four children with obviously abnormal visual behaviour, two of 10 children with strabismus and four of 11 with large refractive errors were detected in the follow-up examination. Thus the target conditions were detected at the follow-up examination in only six of 142 children (4.2%).

Conclusions: Although ophthalmic abnormalities are common in children born prematurely, most of them are identified because high-risk children are followed regularly in eye clinics and because parents and primary health care personnel detect strabismus. Ophthalmological follow-up of all children born before 32 weeks appears not to be worthwhile and is therefore only recommended for high-risk children.
