PURPOSE: To study the frequency and possible causes of severe corneal opacities in premature infants undergoing retinopathy of prematurity (ROP) screening in the neonatal intensive care unit (NICU) at a single institution.
METHODS: The medical records of all infants screened for ROP in the NICU between January 2015 and March 2019 were reviewed retrospectively. Criteria for screening were gestational age (GA) of <32 weeks or birth weight (BW) <1501 g. Characteristics of premature infants with severe corneal opacities were extracted from the record.
RESULTS: A total of 445 premature infants were screened during the 51-month period. The prevalence of severe corneal opacities was 1.4% (6 infants). The median GA of the affected infants was 24.5 weeks (range, 23-32), and the mean BW was 624 g (range, 500-860 g). Two infants had lagophthalmos; their corneal opacity was unilateral. All the infants were under continuous positive airway pressure (CPAP) for a prolonged period. All 4 infants with bilateral corneal opacities required treatment for severe ROP-laser (n =1), bevacizumab injection (n = 1), or both (n = 2).
CONCLUSIONS: Severe corneal opacities in premature infants are rare but potentially sight threatening, because they can hinder the retinal examination. Lagophthalmos-related exposure keratopathy is an obvious risk factor. CPAP therapy may be another risk factor leading to the development of severe corneal opacities. Identification of infants at risk and prompt commencement of lubricants is necessary to avoid long-term corneal opacities.
