Linear nondisplaced orbital floor fractures with muscle entrapment occur in the pediatric population. These fractures occur with minimal trauma and few external signs of injury. This study reviews the clinical findings, radiologic findings and interpretations, preoperative and postoperative ocular motility, and outcomes in this subset of orbital fracture patients treated with early surgical repair. ⋯ Despite prompt surgical repair, limited elevation and depression occur in the early postoperative period, possibly due to muscle edema, hemorrhage, and ischemia. Recovery of normal ocular motility may take weeks or months. External signs of injury may be minimal and radiologic interpretation may not recognize fracture or muscle entrapment.

To determine whether lowering oxygen saturation alarm limits for infants at risk for retinopathy of prematurity (ROP) reduces its incidence and/or severity. ⋯ A simple change in oximeter alarm parameters in the first weeks of life for infants with a birth weight 1250 g or less may decrease the incidence of prethreshold ROP.

Comparative Study
Unilateral lateral rectus muscle recession and medial rectus muscle resection with or without advancement for postoperative consecutive exotropia.
To evaluate the effectiveness of unilateral lateral rectus muscle recession and medial rectus muscle resection with or without advancement in treating postoperative consecutive exotropia. ⋯ Unilateral lateral rectus muscle recession and medial rectus muscle resection with or without advancement is an effective alternative for treating postoperative consecutive exotropia.

Although the ocular motility examination has been used traditionally in the diagnosis of strabismus that is a result of cranial nerve (CN) abnormalities, magnetic resonance imaging (MRI) now permits the direct imaging of lesions in CN palsies. ⋯ High-resolution MRI can directly demonstrate pathology of CN3 and CN6 and affected EOM atrophy in strabismus caused by CN palsies. Direct imaging of CNs and EOMs by MRI is feasible and useful in differential diagnosis of complex strabismus.
