Clinical examination of patients affected by plagiocephaly or trigonoc
ephaly reveals evident malformation of the orbits, and the ocular repe
rcussions are more pronounced when children are operated on at an adva
nced age. Since it is generally accepted that binocular vision is full
y developed by approximately 6 months of age, a late correction of pla
giocephalic or trigonocephalic skull deformities may be an obstacle to
the development of normal visual function. For the present report we
investigated astigmatism and strabismus in 53 children, 39 of whom wer
e operated on for plagiocephaly and 14 for trigonocephaly. Traction on
the ocular globe induced by the bony deformation caused by the cranio
synostosis may explain astigmatism and strabismus.
