This study investigated the topographic relationships among the eyeball and four orbital margins with the aim of identifying the correlation between orbital geometry and eyeball protrusion in Koreans. Three-dimensional (3D) volume rendering of the face was performed using serial computed-tomography images of 141 Koreans, and several landmarks on the bony orbit and the cornea were directly marked on the 3D volumes. The anterior-posterior distances from the apex of the cornea to each orbital margin and between the orbital margins were measured in both eyes...

Optic nerve sheath meningiomas (ONSMs) account for less than 2% of meningiomas and 1.7% of orbital tumors. Although rare, the management of these tumors is important as unilateral blindness often results in untreated cases. Radiotherapy has emerged as the preferred treatment. However, therapies for ONSMs are controversial due to the variable natural history of the disease and limitations of surgical and radiotherapy options. A 60-year-old woman presented with monocular left diminished color perception and blurred vision...

The superior orbital fissure syndrome (SOFS) is a rare condition presenting as painful unilateral opthalmoplegia, ptosis, pupillary dilatation and anesthesia of the upper eyelid and forehead. It has been described after facial trauma. Other etiologies include infections, tumors or spontaneous hemorrhages in the retro-orbital space. Occurrence of SOFS after surgery in the skull base has not been described before. We recently encountered a case where a young female developed SOFS following surgery for cerebrospinal fluid (CSF) rhinorrhea...

Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery...

REVIEW
Esra Şahlı, Kaan Gündüz
Thyroid-associated ophthalmopathy is the most frequent extrathyroidal involvement of Graves' disease but it sometimes occurs in euthyroid or hypothyroid patients. Thyroid-associated ophthalmopathy is an autoimmune disorder, but its pathogenesis is not completely understood. Autoimmunity against putative antigens shared by the thyroid and the orbit plays a role in the pathogenesis of disease. There is an increased volume of extraocular muscles, orbital connective and adipose tissues. Clinical findings of thyroid-associated ophthalmopathy are soft tissue involvement, eyelid retraction, proptosis, compressive optic neuropathy, and restrictive myopathy...

Conjunctival tumors encompass a broad range of diagnoses. The 3 most important malignant tumors include ocular surface squamous neoplasia (OSSN) (14%), melanoma (12%), and lymphoma (7%). Conjunctival malignancies are rarely found in children. Regarding OSSN, pre-disposing conditions include chronic solar radiation, immune deficiency (HIV), organ transplant, autoimmune conditions, xeroderma pigmentosum, and chronic exposure to cigarette smoke. OSSN is managed surgically or with topical/injection immunotherapy or chemotherapy...

BACKGROUND: Standard anthropometric methods applied to measurements of the skull differentials are laden with mistakes stemming from the way the measuring devices are built and from a lack of experience on the part of the researchers. To increase objectivity, digital imaging measurements via computer systems were introduced. OBJECTIVES: The aim of this research was to assess the asymmetry of the male and female orbit with the application of the new graphic methods: raster graphics and vector graphics...

A 76-year-old male patient underwent magnetic resonance angiography of the head and neck vessels due to a recent incident of transitory ischemic attack. Cerebral angiogram uncovered the double proximal origin of the median unpaired pericallosal artery from the duplicated anterior communicating complex. The vessel curved around the corpus callosum and irrigated the paracentral lobule and the medial parietal cortical areas. The main trunks of the anterior cerebral arteries showed a branching pattern of the marginal callosal arteries, supplying orbital and frontal territories...

Geriatric patients (age ≥ 65) are prone to complications after surgery and are at risk for severe thyroid eye disease (TED). In this study, we aim to identify preoperative demographic and TED patterns associated with geriatric patients who underwent decompression surgery, to examine the effect of age on postoperative strabismus rates, and to identify factors that may contribute to postoperative strabismus in the geriatric subgroup. We retrospectively reviewed patients who underwent thyroid-related orbital decompression surgery at the Kellogg Eye Center, University of Michigan, between 1999 and 2014...

We present a case of severe orbital myiasis caused by Osteris ovis, also known as sheep nasal botfly which is an uncommon manifestation of maggot infestation. Our patient was successfully treated with oral as well as topical ivermectin. The experience of ivermectin as an anti-parasitic agent in the treatment of orbital myiasis, although a known entity, is still limited among medical professionals including ophthalmologists. Thus, we would like to highlight the role of oral ivermectin as an anti-parasitic agent in the treatment of orbital myiasis facilitating the removal of maggots; thus, precluding the need for exploratory surgery...

BACKGROUND: Head and neck ossifying fibroma (OF) is a rare, benign, locally aggressive, fibro-osseous tumor. The mandible is the most common site of involvement, followed by the maxilla, and, less frequently, the sinonasal cavities, orbit, skull base, and calvarium. In this study, we aimed to expand our understanding of this entity by presenting a case series of OF that involved the maxilla and sinonasal tract. METHODS: A multicenter retrospective review was performed on all the patients with a diagnosis of OF from 2004 to 2013...

Accidental removal of the lacrimal gland is a rare complication of ptosis surgery. We report two children who underwent large unilateral levator palpebrae superioris resections (LPSr). After surgery, both patients developed dry eye. Post-operatively, the parents of both patients noticed no tears in the affected eye when their child cried. Computed tomography proved the absence of the lacrimal gland in the operated eye in both patients. Oculoplastic surgeons should pay close attention to the anatomy of the levator muscle and its proximity to surrounding tissues in order to avoid lesions on important orbital structures, including the lacrimal gland, and to avoid the development of long-term dry eye...
