Purpose: To report a case of persistent corneal epithelial erosion in a patient undergoing treatment with erlotinib for her lung cancer.

Methods: Report of a 79-year-old woman who presented with a persistent corneal epithelial defect associated with infectious keratitis that waxed and waned for 5 months despite treatment. She had been diagnosed with lung cancer and was being treated with erlotinib, a reversible epidermal growth factor receptor (EGFR) inhibitor.

Purpose: To assess whether the rate of change of retinal vessel diameter can help identify infants at the highest risk for severe retinopathy of prematurity (ROP).

Design: Thirty-five infants at risk for ROP were included in this prospective, longitudinal study.

Methods: Images were obtained using the NIDEK NM200D noncontact camera (NIDEK Inc, Aichi, Japan) at the time of ROP examinations in the intensive care unit.
