RESUMO
Superior oblique muscle palsy is a frequently encountered acquired muscle deficit accounting for vertical and torsional diplopia. There were two cases of residual isolated superior oblique palsy following anterior ethmoidal artery ligation for epistaxis, a finding not previously reported. The mechanism is suggested to be due either to direct trochlear damage by separation from the periosteum or to localized hematoma formation beneath the periosteum with resultant fibrosis and displacement of the trochlea from its normal apposition to the frontal bone.

Corneal curvature was evaluated in 70 children by central keratometric measurements. The mean keratometric reading in each age group was seen to decline systematically from birth to about 54 months of age. The mean in the newborn-to-6-month-old group was 47.59 D; in the 12-18-month-old group it had decreased to 45.56 D. The cornea appears to stabilize at about 54 months, with an average reading of 42.69 D. Evaluation of 11 eyes diagnosed as having persistent hyperplastic primary vitreous revealed that eyes with this diagnosis generally have steeper corneas than normal eyes at any given age.
