    A 4-week-old boy presented to the pediatric clinic for a well-child examination. The patient was born at 37 weeks’ gestation, and his growth and development had been normal up to this point. Pediatric course had been complicated only by difficulties latching due to ankyloglossia, gastroesophageal reflux disease, and milk protein intolerance.

    During the visit, the patient’s mother reported that she noticed he was experiencing a mild drooping of his right eyelid that improved when he opened his jaw (Figure 1). She also noticed that the patient’s right upper eyelid was elevating rhythmically during feeding (Figure 2). The patient had no other abnormal eye movements or signs of eye discomfort other than while suckling, and he was able to keep his eyes completely open when alert.

    The patient’s mother denied any family history of ocular abnormalities. On physical examination, the patient’s head, eyes, ears, nose, and throat were normal; his cardiac, pulmonary, neurologic, and musculoskeletal examinations also were normal.

     

    Based on the patient’s background and presentation, what is your diagnosis?

    A. Bell palsy

    B. Horner syndrome

    C. Marcus Gunn syndrome

    D. Corneal abrasion

    E. Congenital fibrosis of the extraocular Muscles (CFEOM)
