Subjects and methods
Parents of neonates were asked to take part in the study in the maternity units of The Northern General Hospital and Jessop Hospital for Women in Sheffield during a 12-month period (from December 1999 to November 2000). The parents gave written informed consent to the examination of their child.
The first examination was performed at 1 day postdelivery or as close to this as possible (range 1 to 4 days). General external ophthalmic observations were made and documented. Pupils were dilated using
Results
Sixty infants were examined. Data for seven neonates either were incomplete or were examined in the Special Care Baby Unit (SCBU) and therefore excluded to ensure that the data analysis only included those neonates without systemic conditions. Data were analyzed for a total of 53 neonates.
The number of infants with retinal hemorrhage was 18 (33.96%); 14 were bilateral. Table 1 summarizes the demographic data for the cohort as a total and for those infants found to have retinal hemorrhage. The
Discussion
The RetCam 120 is a portable digital imaging system that provides high-resolution real-time images of retinal hemorrhages without the need for sedation or general anesthesia in young children and infants. Traditionally retinal hemorrhages are documented in a freehand drawing by the examining clinician and, while these drawings are useful, real-time digital photographs provide much better documentation. The RetCam 120 provides a 120-degree field-of-view and therefore peripheral hemorrhages can
