One-and-a-half syndrome (OHS) is a horizontal gaze palsy in one direction with internuclear ophthalmoplegia (INO) in the other. The only eye movement possible is the abduction of the contralateral eye with nystagmus. The usual structures affected are the medial longitudinal fasciculus and paramedian pontine reticular formation or the abducens nucleus. Most commonly, the OHS is caused by ischemia and demyelinating lesions. The other causes include infectious, neoplastic, and rarely traumatic. We report a case of a 42-year-old non-compliant hypertensive female who presented with giddiness, projectile vomiting, and right-sided hemiparesis and was found to have OHS on cranial nerve examination in the emergency department (ED). In the ED, the presence of complete horizontal gaze palsy in one direction with INO in the other direction should raise suspicion of a brainstem pathology.

Because intraoperative rupture of RK incisions during clear corneal phacoemulsification is a known complication and was postulated to occur in an eye with deeper incisions that had not completely healed, 10 3 RK scars were sutured intraoperatively before phacoemulsification to prevent further dehiscence and to maintain a closed globe. We describe a unique case of traumatic iris expulsion through a full-thickness dehiscence of an RK scar 30 years after the initial surgery. Although RK has become obsolete, it is important for clinicians to inform patients about the lifelong risk of traumatic globe rupture after minor blunt trauma and to counsel on the use of protective polycarbonate lenses, particularly during high-risk activities.
