Early Vision Screening in High-risk Children

Early Vision Screening With Automated Photorefraction in Pre-term, Low-birth- Weight and Development-delay Children in Far-Eastern Memorial Hospital, Taiwan

To evaluate the effect of early vision screening with automated photorefraction device in high risk children

Pre-term, low-birth-weight, and development delay are well-known risk factors related to higher incidence of high refractive error and strabismus, which can potentially lead to amblyopia and is regarded as amblyopia risk factors. This project is a cross-sectional controlled study. Our study includes high-risk group and normal group. High-risk group includes children with birth history of pre-term, low-birth-weight and the diagnosis of development delay in FEMH. Normal group enrolled age-matched children without those risk factors. Vision screening by FDA-approved photorefraction device as well as comprehensive ophthalmic exams for definite diagnosis will be performed on the high-risk group and the normal group.

Inclusion Criteria:

• High risk group: children with gestational age less than 36weeks, birth weight less than 2500g and children diagnosed as develop delay
• Normal group: children with normal birth history and normal development
