The central retinal thickness was significantly higher in the preterm groups than in the full-term group. This subtle macular modification may be related mainly to ROP. Prematurity had only a marginally significant role.

The prevalence of myopia < or =-4,0 D and visual acuity <0.8 appears to be increased even with mild posterior pole changes. Birth weight does not seem to be significant factor in the prevalence of myopia < or =-4.0 D following laser coagulation of stage 3 threshold ROP.
