Abstract
The aim of this study was to evaluate the posterior segment in pediatric patients with corneoscleral lacerations using B-scan ultrasonography. This prospective (follow up) study was carried out on 50 eyes of children with traumatic corneoscleral lacerations. A corneoscleral laceration is an injury that may occur following blunt, or penetrating ocular trauma. Injuries to other structures in the eye such as the lens, uvea, retina, or vitreous may accompany that type of injuries. The exact incidence of corneoscleral lacerations is unknown, but Eye injuries measure about 8%–14% of the total childhood injuries. Predicting the visual outcome in patients with corneoscleral lacerations is difficult. The outcome is generally poor in patients with poor visual acuity at presentation, patients with delayed presentation, and those who sustain agricultural-related injuries. Patients with a small corneoscleral laceration without any other intraocular injury have a better prognosis. Patients with other intraocular injuries, intraocular foreign bodies, endophthalmitis, and late presentation tend to have a poor prognosis. Ocular trauma is one of the leading causes of treatable visual morbidity and blindness with children at a greater risk due to careless activities and inability in understanding the nature of dangerous objects. Ninety percent of eye trauma is preventable by taking care of minor things. Ophthalmic ultrasonography is a diagnostic imaging modality for directly evaluating lesions of the posterior segment in eyes with opaque ocular media caused by corneal opacities, anterior chamber opacities, lens opacities, vitreous hemorrhage, inflammatory opacities which make clinical examination and ophthalmoscopic examination difficult and less informative. For example, B-scan ultrasonography provides useful information regarding the presence of ocular foreign bodies of any kind when other radiological investigations (X-Ray) become negative. B-scan gives the exact location of the foreign body in the eye and the extent of damage to the surrounding tissues such as lens, vitreous, retina and guides the therapeutic decision related to late effects of ocular trauma.
