Risk of Nonarteritic Anterior Ischemic Optic Neuropathy in Patients Prescribed Semaglutide.

Importance: Anecdotal experience raised the possibility that semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1 RA) with rapidly increasing use, is associated with nonarteritic anterior ischemic optic neuropathy (NAION).

Objective: To investigate whether there is an association between semaglutide and risk of NAION.

Design, Setting, And Participants: In a retrospective matched cohort study using data from a centralized data registry of patients evaluated by neuro-ophthalmologists at 1 academic institution from December 1, 2017, through November 30, 2023, a search for International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code H47.

Perioperative Vision Loss after Non-Ocular Surgery.

Perioperative vision loss (POVL) may cause devastating visual morbidity. A prompt anatomical and etiologic diagnosis is paramount to guide management and assess prognosis. Where possible, steps should be undertaken to minimize risk of POVL for vulnerable patients undergoing high-risk procedures.

Vision Testing in the Evaluation of Concussion.

Traumatic brain injury results from an acute impact to the head causing brain dysfunction. Concussion is a form of mild traumatic brain injury. There are significant short- and long-term sequelae of concussion, and early diagnosis and management are key to recovery.

Medication-Related Pseudotumor Cerebri Syndrome.

Pseudotumor cerebri syndrome refers to elevated intracranial pressure associated with papilledema without an identified etiology for intracranial hypertension. Over the past few decades, several medications have been described to be associated with this syndrome. We searched the literature for those case reports and series and evaluated the evidence for the association of such medications with pseudotumor cerebri syndrome.

The Ophthalmic Clinical Evaluation Exercise (OCEX).

Purpose: New concise tools must be developed to assess reliably and validly the core residency competencies identified by the Accreditation Council for Graduate Medical Education.

Participants: Eighteen content experts (residency program directors).

Methods: A 1-page Ophthalmic Clinical Exercise Examination (OCEX) checklist, for use during observed resident-patient interactions, was developed by an American Board of Ophthalmology taskforce.
