Growth and development of children and youth with impairment of sight

1.	Analysed children and youth with impairments of sight in comparison to normal peers indicated a deficit in height and weight.
2.	Blind children are shorter than partially sighted children.
3.	The girls with impairments of sight matured earlier then their peers from Wroclaw. More severe the impairment of sight is, earlier the age at menarche
4.	The girls with acquired defects (in 80% preterm borns), though the shortest, matured the earliest from all studied girls.

The age at menarche is a feature more likely to be influenced by the impairment factor and the severity impairment of sight than somatic features.
