Comparative Study
Comparison of visual acuity levels in pediatric patients with amblyopia using Wright figures, Allen optotypes, and Snellen letters.
To compare and correlate the clinical performance of Wright figures in visual acuity assessments of pediatric patients with amblyopia to those obtained through Allen cards and Snellen letters. ⋯ Wright figures, designed primarily to evaluate the vision in the preliterate pediatric population, correlate more closely to Snellen letters and have a higher rate of correctly identifying amblyopia than isolated Allen optotypes in pediatric patients.

To establish child abuse as part of the differential diagnosis of isolated bilateral subconjunctival hemorrhages in infants. ⋯ Nonaccidental trauma should be considered in the differential diagnosis of bilateral isolated subconjunctival hemorrhages in infants especially if associated with facial petechiae. These isolated subconjunctival hemorrhages may be part of the traumatic asphyxia syndrome caused by severe, prolonged compression of the child's chest and upper abdomen. Appropriate assessment includes a complete ophthalmic and pediatric examination as well as hematological testing and imaging studies. If the coagulation profile and initial imaging studies are normal yet there remains a high suspicion of abuse, an immediate nuclear scan or a repeat skeletal survey or chest film 2 weeks later is indicated.
