This work seeks to establish the effectiveness of a newborn screening program for detecting ocular pathology in the healthy, full-term neonate. The screening utilizes the Retcam wide-field digital imaging system (Clarity Medical Systems, Pleasanton, CA). Early detection may lead to treatments that can prevent blindness and visual disability.
Neonates born in the Maternal and Children’s Hospital of Kunming, China, were screened within seven days after birth using flashlight, retinoscope, hand-held slit lamp microscope and wide-angle digital retinal image acquisition system (RetCam 2). External eye, pupillary light reflex, red reflex, the opacity of refractive media, anterior chamber, and posterior segment were examined.
A total of 3573 healthy neonates were enrolled in the screening program, with detection of 848 abnormal cases (23.73%). The abnormal exams included 769 retinal hemorrhage (21.52%). Of these there were 215 cases of significant retinal hemorrhage representing 6.02% of the total. In addition, 67 cases (1.88%) involved macula hemorrhage. The other 107 cases (2.99%) included: subconjunctival hemorrhage, lacrimal duct obstruction, congenital microphthalmos, congenital corneal leucoma, posterior synechia, persistent pupillary membrane, congenital cataract, enlarged C/D ratio, retinoblastoma, optic nerve defects, abnormal distribution of macular pigment, and non-specific peripheral retinopathy.
Screening of all healthy newborns leads to detection of a significant number of ocular pathologies. RetCam photodocumentation is a safe, convenient, fast, and objective technique to screen newborns, enabling timely treatment and detailed follow-up including longitudinal observation of lesions.
