An 8-year-old male presented to the pediatric emergency department with subjective fever, blurry vision, and left eye pain. On physical examination, there was mild left lower lid erythema and a subtle left eye elevation deficit. Computed tomography demonstrated preseptal soft tissue swelling without orbital involvement; however, there was varying amounts of paranasal sinus opacification. Despite the negative scan, a diagnosis of orbital cellulitis associated with sinusitis was made and treatment with intravenous antibiotics was initiated...

Blastomyces species are thermally dimorphic fungi existing as yeast in tissue. We report an initially immunocompetent patient with orbital apex syndrome (OAS) whose presentation suggested giant cell arteritis. Subsequently, metastatic carcinoma was entertained as a cause of OAS until bronchoscopy yielded Blastomyces species. The patient rapidly succumbed with multiorgan failure despite Amphotericin B administration. At post-mortem, Blastomyces co-infection with fungal hyphae in keeping with Aspergillus species was found in cavernous sinus and in infarcted optic nerve...

Objective: Thyroid orbitopathy is a poorly understood extrathyroidal manifestation of Graves' disease that can cause disfiguring proptosis and vision loss. Orbital decompression surgery for Graves' orbitopathy (GO) can address both cosmetic and visual sequelae of this autoimmune condition. Endonasal endoscopic orbital decompression provides unmatched visualization and access to inferomedial orbital wall and orbital apex. This review examines the state of the art approaches employed in endonasal endoscopic orbital decompression for GO...

Background: Hemangiopericytomas are a rare entity commonly presenting as subdural tumors. Case Description: A 57-year-old man presented with a progressive visual disturbance over a period of 3 weeks. Cranial computed tomography scans revealed an isodense mass at the tip of the left middle fossa, extending into the orbital apex, and accompanying bony erosions in the sphenoid ridge. On magnetic resonance imaging, the lesion appeared isointense both on T1- and T2-weighted sequences, and intensely enhanced on contrast examinations...

OBJECTIVE: The aim of this study was to identify key anatomical landmarks useful in gaining access to the anteromedial temporal region via the corridor formed by the inferior orbital fissure (IOF), the ophthalmic branch (V1), and the maxillary branch (V2) of the trigeminal nerve via the EEA. METHODS: An anatomical dissection of six cadaver heads was performed to confirm the feasibility and applicability of the EEA for accessing the anteromedial temporal region. RESULTS: Following middle turbinectomy, the lateral recess of the sphenoid sinus was opened, the orbital apex exposed, and the posterior wall of the maxillary sinus was removed, in sequence...

Background and importance: High flow orbital apex or middle fossa cerebrospinal fluid (CSF) leaks can be life threatening and complex to repair. These leaks associated with large dural defects are most commonly repaired with an open temporalis muscle patch or free flaps, but these flaps do not always stop the leak. Clinical Presentation: A 65-year-old patient presented two years after orbital exenteration and radiation for squamous cell carcinoma. He developed multi-organism meningitis and pneumocephalus secondary to a large high-flow orbital apex/middle fossa CSF leak...

Molar apical elongation (MAE) was the leading cause for euthanasia or death in a captive breeding colony of endangered Amargosa voles ( Microtus californicus scirpensis). Clinical signs included ocular discharge, abnormal mastication, dyspnea, abnormal mentation, weight loss, and death. Although the severity varied, all molars in all quadrants were affected. When severe, the overgrown molar reserve crown and apex protruded into the nasal meatuses, the orbit, the calvarial vault and through the ventral margin of the mandible...

A 22-year-old male presented to us with complaints of sudden painful loss of vision in left eye 10 days ago along with inward deviation of the left eye. Best-corrected visual acuity (BCVA) in right eye was 20/20 and 20/50 in left eye. Left eye showed limitation of abduction, a relative afferent pupillary defect, normal anterior segment with optic disc oedema. Contrast-enhanced MRI of the brain and orbit showed thickening of left optic nerve along with a cystic lesion near the orbital apex with a central iso- to hyperintense spot resembling a scolex...

Orbital apex syndrome is a rare complication of herpes zoster ophthalmicus. A patient being followed in our clinic for herpes zoster ophthalmicus developed orbital apex syndrome in the second week of treatment. Clinical diagnosis was supported by magnetic resonance imaging. Treatment with systemic steroid and antiviral therapy resulted in total regression of ophthalmoplegia at 2 months. However, optic neuropathy-induced vision loss was permanent. This case report examines orbital apex syndrome secondary to herpes zoster ophthalmicus, which has rarely been documented in the ophthalmic literature...
