- Superior limbic keratoconjunctivitis (SLK) is an inflammatory condition of the superior bulbar conjunctiva, tarsal conjunctiva, and upper cornea of unknown etiology. The pathogenesis of SLK is unclear, although it has been linked to mechanical microtrauma, deficiencies in tear film quality, and immunologic dysregulation.1
- Carotid cavernous fistula (CCF) is a rare traumatic complication that can occur following iatrogenic interventions.1 We report a case of direct CCF (type A) developing following partial maxillectomy with the Le Fort I approach. This case report adheres to the ethical principles outlined in the Declaration of Helsinki as amended in 2013.
- Lacrimal gland pleomorphic adenoma (LGPA) is a common benign epithelial tumour of the lacrimal gland that frequently appears on imaging as a well-circumscribed lesion with no bony erosion.1 In some cases, it can present with atypical radiologic features and then needs to be correlated with histopathologic findings to ascertain a diagnosis.
- Adult orbital xanthogranulomatous disease is a rare non-Langerhans cell histiocytic condition with 4 clinical subtypes: adult‐onset xanthogranuloma, adult‐onset asthma with periocular xanthogranuloma, necrobiotic xanthogranuloma (NBX), and Erdheim–Chester disease (ECD). We report, to our knowledge, the first case of ECD with limbal infiltration.
- Necrotizing fasciitis (NF) of the periorbital region is a rare occurrence, though has been shown to cause severe facial disfigurement, blindness, and death.1,2 We report a case of community-acquired methicillin-resistant Staphylococcus aureus (MRSA)–associated periorbital NF in a 25-year-old woman, who presented with left eye and nostril redness and swelling after picking a pimple on her nose a few days prior. She had no significant medical history and was not diabetic. She was initially diagnosed with facial cellulitis and commenced on antibiotics, but returned 2 days later with worsening cellulitis, bilateral leg pain and redness, and shortness of breath.
- Granulomatosis with polyangiitis (GPA) is a multisystemic, antineutrophil cytoplasmic antibody (ANCA)–associated small vessel vasculitis. The orbit and ocular tissues are implicated in approximately a third of cases.1 Common manifestations are conjunctivitis, episcleritis, orbital inflammation, and uveitis.1
