Relative Frequencies of Arteritic and Nonarteritic Anterior Ischemic Optic Neuropathy in an Arab Population.

Background: To evaluate the relative frequencies of arteritic and nonarteritic anterior ischemic optic neuropathy (AION) in an Arab population and to compare and contrast these findings with known epidemiological data from Caucasian populations.

Methods: A retrospective review of the medical records of all patients diagnosed with AION at the King Khaled Eye Specialist Hospital (KKESH) in Riyadh, Saudi Arabia, between 1997 and 2012.

Results: Of 171 patients with AION, 4 had biopsy-proven giant-cell arteritis (GCA).

Oculocardiac reflex in a medial orbital wall fracture without clinically evident entrapment.

In this report, we describe a patient with a medial wall orbital fracture, who presented with vasovagal-like symptoms secondary to an oculocardiac reflex. This case is unusual because the patient had no other clinical evidence of muscle entrapment. A 15-year-old male presented with daily 5-10 min episodes of dizziness, light headedness, and nausea consistent with a vasovagal reaction.
