Findings of Eye Screening Examinations with Wide-Field Digital Imaging System in Healthy Newborns

Abstract

Purpose: To present the results of eye screening examinations using RetCam in healthy newborns. Methods: Eye screening examinations were performed using the RetCam wide-field digital imaging system (Clarity Medical System, Pleasanton, CA, USA), as requested by parents, on healthy newborns within a week after birth in an obstetrics and gynecology hospital between June 2012 and September 2014. During the examination, photographs were taken showing red reflex and the fundus. The reading was conducted by a pediatric ophthalmologist. Results: The examinations included a total of 10,023 newborn babies, and abnormalities were discovered in 2,916 patients (29.09%). The most commonly found abnormality was retinal hemorrhage, which was discovered in 2,796 babies (27.89%) and 471 patients showed a large amount of bleeding or macular hemorrhage. In 71 patients (0.7%), ophthalmologic examination was recommended after newborns presented with one of the following conditions: congenital cataracts, retinoblastoma, persistent hyperplastic primary vitreous, vitreous hemorrhaging, persistent pupillary membrane, choroidal nevus or albinism. Due to unclear photographs, 85 eyes of 49 patients (0.48%) could not be read. Conclusions: Ophthalmologic screening using RetCam is a safe, simple and useful technique for discovering ophthalmologic abnormalities. Additionally, when abnormalities are suspected, the role of a pediatric ophthalmologist is increasingly important in helping patients receive appropriate ophthalmologic treatment. Furthermore, retinal hemorrhage, which occurred in the majority of all observed abnormalities, requires further investigation to examine the possibilities of amblyopia in cases with a large amount of bleeding or macula involvement.
