Clinical features and management of posttraumatic subperiosteal hematoma of the orbit.

Traumatic subperiosteal hematoma (SpH) usually presents late, after the initial trauma. It is generally seen in young males. Computed tomography is the best mode of imaging and helps to rule out orbital fracture or associated subdural hematoma. We present the clinical features and management of four patients seen at the orbit clinic with SpH. Management is based on time of presentation, visual acuity and any communicating bleed. The prognosis of traumatic SpH is excellent if treated with an individualized patient approach.

Atypical presentation of an unusual foreign body.

A 14-year-old boy presented with intractable diplopia for 10 days following an assault. A thorough history revealed that he was unaware of any penetrating injury. However, imaging demonstrated a radiolucent foreign body between the globe and the orbital floor. On surgical exploration, it was found to be the proximal part of a ball point pen. Its removal resulted in complete resolution of diplopia. Thorough clinical and radiological examination is recommended when a foreign body is suspected in pediatric patients. Prompt diagnosis will aid in early intervention and prevention of long-term complications.

Clinical profile of cerebral venous sinus thrombosis and the role of imaging in its diagnosis in patients with presumed idiopathic intracranial hypertension.

Retrospective descriptive study reporting the rate of occurrence of cerebral venous sinus thrombosis (CVST), highlighting the role of magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) in patients with presumed idiopathic intracranial hypertension (IIH). Study was conducted in the department of neuro-ophthalmology at a tertiary eye care center in South India. Data from 331 patients diagnosed with IIH from June 2005 to September 2007 was included. Inclusion criteria were: Elevated opening cerebrospinal fluid (CSF) pressure of more than 200 mm of water on lumbar puncture, normal CSF biochemistry and microbiology, and normal neuroimaging as depicted by computed tomography(CT) scan. Exclusion criteria were: Space-occupying lesions, hydrocephalus, meningitis, intracranial pressure within normal range, abnormal CSF biochemistry and microbiology. The remaining patients were evaluated with MRI and MRV. CVST was present in 11.4% of patients who were presumed to have IIH (35/308). MRI alone identified 24 cases (68%) of CVST, while MRI used in combination with MRV revealed an additional 11 cases (32%). Risk factors associated with CVST were identified in nine out of 35 patients (26%). CVST may be misdiagnosed as IIH if prompt neuroimaging by MRI and MRV is not undertaken. Risk factors of CVST may not be apparent in all the cases and these patients are liable to be missed if CT scan alone is used for neuroimaging, hence MRI, combined with MRV should be undertaken to rule out CVST.

Multimodality treatment approach in management of primary peripheral primitive neuroectodermal tumor of the orbit.

Primitive neuroectodermal tumor is a small round cell malignancy which rarely involves the orbit. We report a case of a two-year old male child presenting as unilateral eccentric proptosis with extraconal and intraconal mass, diagnosed as primary peripheral primitive neuroectodermal tumor (pPPNET) on histopathology and immunohistochemistry. There is no defined consensus in the management of these tumors due to its rare presentation. We describe its distinguishing features with emphasis on multimodal and aggressive treatment approach which ensures appropriate management of these cases.

Delleman Oorthuys syndrome: ‘Oculocerebrocutaneous syndrome’.

Delleman Oorthuys syndrome (oculocerebrocutaneous syndrome) is a rare, congenital sporadic disorder affecting the skin and central nervous system. We present the case of a one-month-old male who presented with an orbital cyst in the left eye since birth along with other manifestations of this syndrome. The manifestations of this syndrome resemble other developmental disorders like Goldenhar and Goltz syndrome. Conservative management of the orbital cyst in these cases have been described. The need to diagnose this rare congenital anomaly with cerebral malformations as a separate entity is crucial in the management of these children.

Ophthalmic complications including retinal detachment in hyperimmunoglobulinemia E (Job's) syndrome: Case report and review of literature.

Hyperimmunoglobulinemia E (Job's) syndrome is characterized by markedly increased levels of immunoglobulin E, recurrent cutaneous and systemic pyogenic infections, atopic dermatitis, and peripheral eosinophilia. Although ocular involvement in Job's syndrome is rare, there are reports of keratoconus, staphylococcal chalazia with blepharitis, and Candida endophthalmitis by various authors. We present the first case report of retinal detachment with complicated cataract in Job's syndrome.
