Aim—Orbital inflammation is common, but the mechanisms underlying leucocytic infiltration of orbital tissue are poorly understood. Human orbital fibroblasts (OF) express chemokines, interleukin 8 (IL-8) and monocyte chemotactic protein 1 (MCP-1), when exposed to proinflammatory cytokines. The eVects of dexamethasone (DEX) and cyclosporin A (CSA) on OF IL-8 and MCP-1 were examined. Methods—Cultu...
Orbital emphysema is an abnormal condition in which air is present within the orbit. We report a rare case of a 19-year-old man who suffered syncopic attacks caused by sniffles following orbital emphysema as a result of trauma. Treating rhinitis is important in patients with orbital emphysema, and patients with cardiac disorders in addition to those with this condition must be warned about the ...
OBJECTIVES The aim of the audit was to determine the common orbital diseases necessitating orbital exenterations at Sekuru Kaguvi Hospital (SKH) between January and December 1999 and recommend ways of reducing the numbers of procedures done annually. DESIGN Retrospective cross sectional study. SETTING Department of Surgery, Parirenyatwa Hospital, University of Zimbabwe. SUBJECTS 23 patien...
Introduction: Orbital pseudotumor, also known as idiopathic orbital inflammatory syndrome (IOIS), is a benign, non- infective inflammatory condition of the orbit without identifiable local or systemic causes. The disease may mimics a variety of pathologic conditions. We present a case of pseudotumor observed in a patient admitted under the name of orbital cellulities. Case Report: A 26-year...
PURPOSE To report on the optic canal cross-sectional area (OCA) in Caucasian patients with normal-tension glaucoma (NTG) compared with Caucasian control subjects without known optic nerve (ON) diseases. METHODS Retrospective analysis of computed tomographic images of the cranium and orbits in 56 NTG patients (30 females and 26 males; 99 of 112 eyes; mean age 67.7 ± 11.1 years). Fifty-six age-...
BACKGROUND Orbital exenteration is a destructive procedure performed by removing all or part of the orbital contents along with entire eyeball. It is a procedure reserved for life threatening malignancies and some nonmalignant disorders which are not controlled by conservative management. METHODS This is a retrospective study done on patients who underwent orbital exenteration at Tilganga Ins...
orbital lynphangioma is a low-flow or no-flow vascular malformation. it is a congenital and isolated hemodynamic lesion in which the clinical presentation and onset are related to orbital, peri-orbital or intracranial involvement. in addition, history of previous trauma and upper respiratory tract infection are important predictor factors. high resolution mri, doppler ultrasound and ct-scan are...
BACKGROUND/AIMS To clarify the pathogenesis of fibrosis in inflammatory orbital diseases, we analysed the gene expression in orbital biopsies and compared our results with those reported for idiopathic pulmonary fibrosis. METHODS We collected 140 biopsies from 138 patients (58 lacrimal glands; 82 orbital fat). Diagnoses included healthy controls (n=27), non-specific orbital inflammation (NSOI...

Mucormycosis is a lethal opportunistic fungal infection, described mostly in immunocompromised patients. A comparative cohort study was conducted to compare the evolution of the study group patients with rhino-orbital mucormycosis, in which a therapeutic protocol was instituted, in which the pterygomaxillary fossa is systematically surgically approached and orbital exenteration is performed or ...
