We report an unusual case of bilateral subconjunctival hemorrhage following mycoplasma pneumonia. A healthy 3-year-old girl developed bilateral subconjunctival hemorrhage at 4 days after the onset of fever and respiratory symptoms such as running nose, cough, and wheezing. Laboratory data were normal except for elevation of Mycoplasma pneumoniae antibodies. The patient was followed without treatment and the subconjunctival hemorrhage resolved in both eyes within two weeks. To the best of our knowledge, this is the first report of subconjunctival hemorrhage following mycoplasma pneumonia. Respiratory symptoms such as cough and wheezing may cause bilateral subconjunctival hemorrhage in infants.
