Abstract
INTRODUCTION: Orbit is a closed sterile compartment surrounded by bony walls and anteriorly by the diaphanous orbital septum. The orbit houses the eyeball and subserves the major functions of protection of the eye and facilitation of the extreme degree of motility by the eye. As such, it may be a secondary site for infection originating in the surrounding structures or an intermediary for infection to other sites. Orbital infections most commonly results from a contiguous source of infection. The orbital anatomy and its relationship to the other adjacent as well as remote structures are essential in understanding the pathogenesis of orbital infections. These relationships also explain the potentially devastating consequences of orbital infection and influence therapeutic decisions. Orbital and periorbital infectious may be caused by variety of bacterial fungal and parasitic agents. Appropriate management depends on recognition of primary source of infection, identification of the responsible organisms and appreciation of the topography of the process within the orbit and periorbital tissues. Integration of the history physical examination and ancillary testing allow the achievement of these primary goals. AIM OF THE STUDY: To analyze the prevalence pattern and etiopathogenesis of orbital infections, to analyse the role of radiological investigations to diagnose orbital infections and to analyse the course of orbital infections with treatment. MATERIALS AND METHODS: Orbital infection was diagnosed in 126 patients who attended Regional Institute of Ophthalmology Government Ophthalmic Hospital between the period of September 2006 to September 2008. Patients who were admitted and treated were included in the study. These patients were evaluated clinically and radiologically. ANALYSIS AND DISCUSSION: Total numbers of cases of orbital infections included in the study period of September 2006 to September 2008 were 126. The study included only the in patients during the study period. SUMMARY: 126 patients who attended Regional Institute of Ophthalmology Government Ophthalmic Hospital between the period of September 2006 to September 2008 with orbital infection were included in the study. The analysis included the prevalence pattern of orbital infections, sex incidence, laterality, associated conditions, efficacy of investigative procedure and the course of disease with treatment. CONCLUSION: Orbital infections are more common in children and preseptal cellulitis is the commonest infection encountered. Periocular infections are the most common associated condition for the orbital infections. Bacteria formed the major causative organism for orbital infections. Among this gram positive organisms predominated. Ultrasonography and CT scan help in diagnosis, identification of complications and in assessment of response of treatment in orbital infections. They are complimentary to each other. Most of the orbital infections resolve with the prompt treatment. Surgical approach forms the treatment of choice in parasitic infections.
