Accidentally diagnosed ocular abnormalities identified during close screening for retinopathy of prematurity

摘要

Purpose To report the variety of ocular findings which have been identified serendipitously during the screening for retinopathy of prematurity (ROP) in a tertiary referral center during seven-year period. Methods The charts of 1568 preterm infants who screened for ROP were reviewed retrospectively. Any ocular lesion except for ROP were noted. All infants had undergone routine ocular examination of the external eye, pupillary light reflex, anterior and posterior segment. Wide-angle digital retinal image acquisition system for any vitreoretinal pathology requiring a close follow-up had been utilized. Results Abnormal ocular findings other than ROP were diagnosed in 296 infants (19.2). Tunica vasculosa lentis was the most common finding (25) followed by vitreous or retinal hemorrhages (17.2) and retinal white lesions (16.6). Retina was the most frequently involved anatomic site. Other frequent ocular findings included optic disc cupping, congenital cataract, optic nerve hypoplasia, choroidal nevus, persistent fetal vasculature, lid hemangioma, and tilted disc. However, life-threatening pathologies such as lipemia retinalis and even retinoblastoma were also diagnosed. Conclusion A duly ophthalmologic examination is mandatory in premature infants for ROP screening. During such examinations, ophthalmologists must be aware of coexisting ocular findings; which could be sight-threatening or even life-threatening.
