Allergic conjunctivitis and contact dermatitis following silicone tube intubationLacrimal stenting systems have been used to maintain patency of the canaliculi after insults such as surgery, trauma, radiation, and chemotherapy. The first nasolacrimal stents were made of silver wire and used by Graue in 1932.1 Since then, other materials have been used, including silk, nylon, polyethylene, and polypropylene. Modern-day stents are most commonly made of silicone because this material is pliable, affordable, and widely available. Previously thought to be inert, there is evidence that silicone can elicit a foreign-body and inflammatory reaction.
Invasive cavernous sinus aspergillosis: an orbitocranial approach for diagnosis and managementSino-orbital aspergillosis classically involves the paranasal sinuses before invading the orbit.1 Early treatment is typically indicated given the aggressive nature of this disease. However, challenges arise given its rarity and ambiguous presentation both clinically and radiographically.2–5 We report an immunocompetent patient with invasive cavernous sinus aspergillosis presenting with limited sinus involvement and illustrate the critical role of biopsy in diagnosis and therapy.
Pagetoid spread of sebaceous cell carcinoma to the corneaSebaceous cell carcinoma (SebCC) is a malignancy that most commonly presents in the eyelid.1 Pagetoid spread to the conjunctiva has been well documented,1-3 but spread to the cornea is less common.4 We report a 64-year-old female who was diagnosed with pagetoid spread of SebCC to her right cornea. She initially presented with a 3-year history of red eyes and trichiasis. After multiple epilations, she was referred to the oculoplastics service for electrolysis. On examination, her visual acuity was 20/70 in the right eye and counting fingers in the left eye (the vision was limited due to a central stromal scar and a dense cataract).
