Etiologies and Outcomes of Granulomatosis With Polyangiitis-Associated Optic Neuropathy: A Case Series and Review of the Literature.

Background: Granulomatosis with polyangiitis (GPA), formerly known as Wegener granulomatosis, is a rare autoimmune disease characterized by inflammation of small- to medium-sized blood vessels (vasculitis). We described the 3 causes of GPA-associated optic neuropathy (compressive, inflammatory, or ischemic) and analyzed initial and final visual acuities (VAs) in each group, which could potentially help prognosticate visual outcomes depending on the etiology of optic neuropathy.

Methods: This was a retrospective chart review of patients who were diagnosed with GPA-associated optic neuropathy and were seen in the Department of Ophthalmology at Mayo Clinic in Rochester, Minnesota.

Acute Optic Neuropathy in Older Adults: Differentiating Between MOGAD Optic Neuritis and Nonarteritic Anterior Ischemic Optic Neuropathy.

Background And Objectives: Myelin oligodendrocyte glycoprotein antibody-associated disease optic neuritis (MOGAD-ON) and nonarteritic anterior ischemic optic neuropathy (NAION) can cause acute optic neuropathy in older adults but have different managements. We aimed to determine differentiating factors between MOGAD-ON and NAION and the frequency of serum MOG-IgG false positivity among patients with NAION.

Methods: In this international, multicenter, case-control study at tertiary neuro-ophthalmology centers, patients with MOGAD presenting with unilateral optic neuritis as their first attack at age 45 years or older and age-matched and sex-matched patients with NAION were included.

The First Cataract Surgeons in the British Isles.

Purpose: To describe the entry of cataract surgery into the British Isles.

Methods: Handbills, books, and other historical sources were reviewed to determine when cataract surgery was first performed in the region.

Results: Roman artifacts suggest that couching was performed in the British Isles in antiquity.
