Utility of Neonatal Ophthalmologic Examination for Detection of Infectious Etiologies for Symmetric Intrauterine...

To determine the utility of ophthalmologic examination as part of evaluation for infection in infants with intrauterine growth restriction (IUGR).

This is a single-institution retrospective chart review of neonates diagnosed with symmetric IUGR or small for gestational age (SGA) who underwent complete ophthalmologic consultation to assess for intraocular findings suggestive of congenital infection. Data collected included other factors that may cause IUGR, findings of general and ophthalmologic examinations, and results of investigation for intrauterine infection. Cost minimization analysis was also performed.

One hundred neonates met the study's inclusion criteria (IUGR, n = 24; SGA, n = 45; IUGR and SGA, n = 31). The mean gestational age at birth was 34.6 ± 3.0 weeks, and the mean birth weight was 1691 ± 530 g; 74% had an identifiable risk factor for IUGR and 84 patients underwent investigation for intrauterine infection. Two of the 73 patients who had urine culture for cytomegalovirus (CMV) were positive (1 of whom had systemic signs of severe congenital infection without eye involvement, the other who had no clinical signs of congenital CMV); evaluations for infection were negative otherwise. No patients had any ophthalmologic signs of congenital infection.

Current literature suggests that routine evaluation of neonates with isolated IUGR for congenital infection may be low-yield and not cost-effective. Our study found that routine ophthalmologic evaluation in newborns with symmetric IUGR who have no systemic signs of intrauterine infection is of little value.
