Subconjunctival Hemorrhages Are Rare Among Infants With Cough and Gastrointestinal Conditions.

Objective: Subconjunctival hemorrhages (SCHs) are uncommon injuries in young children beyond the neonatal period and have been associated with abuse. In otherwise well infants, they are sometimes attributed to commonly observed symptoms that invoke Valsalva maneuvers, such as cough, vomiting, and constipation. Our study aims to ascertain the prevalence of SCH among children presenting to emergency care with cough, vomiting, and constipation.

Methods: We conducted a cross-sectional secondary analysis of a prospectively collected dataset of children aged 1 month to 3 years presenting to a tertiary pediatric emergency department (ED). Children with and without SCH were identified at the time of their examination by ED providers. Children were assigned to Valsalva symptom groups of cough, vomiting, and/or constipation based on review of the ICD-10 codes associated with the ED encounter. Descriptive statistics and prevalence were calculated for each group. Chi-square testing of proportions was used to compare the prevalence of SCH based on the presence or absence of the 3 symptoms of interest.

Results: Four thousand seven hundred seventeen qualifying ED encounters were captured, with 2 total cases of SCH identified (0.4 per 1000). SCHs were uncommonly observed in patients with cough (0.5 per 1000), vomiting (0 per 1000), and constipation (0 per 1000). We found no significant differences in the prevalence of SCH based on the presence or absence of cough (P = 0.87), vomiting (P = 0.52), or constipation (P = 0.82).

Conclusion: SCH is an uncommon finding in children under 3 years and is similarly uncommon among children with cough, vomiting, or constipation. It should not be attributed to uncomplicated presentations of cough, vomiting, or constipation, and alternative diagnoses, including abuse, should be carefully considered in the differential diagnosis of SCH.
