PURPOSE: V-pattern strabismus observed with syndromic craniosynostosis has been attributed to disparate causes. We compared severity of V pattern with degree of excyclorotation of rectus muscles to appraise significance of this proposed aetiology. METHODS: 43 patients with Apert, Crouzon or Pfeiffer syndrome referred to Boston Children's Hospital Department of Ophthalmology were identified. 28 met inclusion criteria for retrospective cohort study, specifically: (1) sensorimotor measurements in minimum of seven cardinal gazes, (2) quantified fundus torsion and (3) orbital CT imaging sufficient to measure rectus muscle cyclorotation in coronal and quasicoronal planes, posteriorly (near orbital apex) and anteriorly (near pulleys)...

Andrew Dawood, Nicholas Kalavresos
This article details the significant complications associated with treatment of a patient who underwent maxillary reconstruction based entirely on zygomatic implants. The use of zygomatic implants is becoming increasingly widespread, and treatment has been shown to be predictable and generally free of surgical complications. However, extending from the maxillary alveolus, alongside or through the maxillary antrum, toward the zygoma or orbital rim, these long implants have the potential to create a range of complications that may be more serious than those encountered with conventional dental implants...

Extraskeletal orbital mesenchymal chondrosarcoma (MC) is an extremely rare and highly aggressive tumour. It has characteristic radiological features and pathognomic histological biphasic pattern. Radical resection with negative margins is the mainstay of treatment; role of adjuvant chemotherapy and radiotherapy is yet not well defined. We report a rare case of 18-year-old man who was diagnosed to have orbital MC. He presented with locally advanced disease with no vision in the affected eye. He underwent right orbital exenteration; a transcranial intradural approach was used to divide the optic nerve, and the temporalis muscle flap was utilised to fill the exenterated orbit...

BACKGROUND: Invasive orbital apex aspergillosis (IOAA) is an aggressive form of aspergillus infection that usually affects immunocompromised patients. It can cause orbital apex syndrome and, if not treated promptly, may progress rapidly causing fatal complications. Subarachnoid hemorrhage (SAH) secondary to ruptured mycotic aneurysms is a very rare complication of invasive aspergillosis. We aim to describe our management and the outcome of six immunocompetent patients with IOAA with subsequent SAH secondary to ruptured mycotic aneurysms...

Orbital apex syndrome is a rare neuro-ophthalmic manifestation of herpes zoster virus infection. We report one such case with favourable outcome in an immunocompetent patient. A 60-year-old woman presented with rash in the dermatome of the left ophthalmic nerve (V1), followed by sudden loss of vision with complete left-sided external and internal ophthalmoplegia. MRI of brain and orbits with contrast revealed optic perineuritis and myositis without intracranial involvement confirming the diagnosis of orbital apex syndrome...

RATIONALE: A cholesterol granuloma (CG) is usually found in the middle ear, papilla, orbits, petrous apex, and choroid plexus, but is highly uncommon in the skull. In spite of benign clinicopathological lesions, bone erosion can be seen occasionally in the patient with CG. The optimal treatment strategy is radical surgery, but complete excision is usually impossible due to anatomical restrictions and a risk of injury to the key structures located nearby. Here, we report a patient with CGs in the suprasellar and sellar regions who was successfully treated with Java brucea and Chinese herbal medicine...

OBJECTIVE: The orbital periosteum is considered to be a barrier to tumor spread; however, it is difficult to evaluate microscopic tumor spread during surgery. This study aimed to assess the impact of pathological status in orbital preservation surgery. METHODS: We retrospectively analyzed the 3-year local control rate and treatment outcomes of patients with malignant tumors invading the orbit who were treated between 2006 and 2012. RESULTS: In total, 27 patients were reviewed over a median follow-up period of 36 months...

This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead to devastating effects if malignant cells seed into the orbit and adjacent cranial nerves as our two patients developed an orbital apex syndrome...

A 23-year-old male with intermittent visual loss in his left eye for 4 months was originally treated as optic neuritis elsewhere. Upon presentation to our hospital (Beijing Tongren Hospital), his left eye visual acuity was reduced to hand motion at face. The left eye ocular motility was limited in upgaze, downgaze, adduction, and abduction. Computed tomography and magnetic resonance imaging revealed lesions in the sphenoid and ethmoid sinuses, orbital apex and carvernous sinus invading adjacent extraocular muscles...

Our aim is to report 13 unusual cases of acquired, temporal sectoral scotomas. Such stationary "wedge" field defects have been reported previously in cases of presumed congenital nasal hypoplasia of the optic disc and as a complication of vitreoretinal surgery. To our knowledge, the literature provides no reports of similar defects occurring spontaneously. This is a descriptive clinical case series of 13 patients presenting with sub-acute monocular temporal visual field loss. All were clinically assessed and investigated with Goldmann perimetry, automated Humphrey visual fields, retinal optical coherence tomography, orbital ultrasound, and standard and multi-focal electroretinography...

A 69-year-old man with prostatic cancer under palliative care developed isolated right-sided oculomotor nerve palsy with pupillary impairment and persistent ocular pain. Cranial magnetic resonance imaging demonstrated metastasis of prostatic cancer to the right-sided cavernous sinus and orbital apex. In the English language literature, there are only six reported cases of isolated oculomotor nerve palsy secondary to prostatic cancer. In all cases, although there was metastatic lesion in the vicinity of the cavernous sinus, ocular pain did not develop...
