Ocular alignment and refraction in preterm children at 1 and 6 years old

Figures & data

Figure 1 Refractive error prevalence at 1 year old and 6 years old in all groups.

Notes: (A) 1 year old; (B) 6 years old. *P<0.05: statistically significant differences of groups 2 and 3, respectively, versus group 1.
Abbreviation: ROP, retinopathy of prematurity.
