ABSTRACT

Background: Type C closed globe ocular trauma (superficial foreign body) is a kind of injury that frequently affects the cornea. If it is not opportunely treated, it may reduce vision when the central zone is affected. Its treatment in an emer-gency service might be limited by the unawareness of the rate of foreign bodies that can be dealt with, because they lay in a thicker cornea zone. Aim: To identify the topography of superficial corneal foreign bodies, in order to learn the rate that can be treated in an emergency service. Method: Ophthalmic consultations con-cerning ocular trauma between 1996 and July 2001 were reviewed. Patients with a diagnosis of superficial corneal foreign body were selected. For the purpose of topography the cornea was divided in five zones: central, superior nasal, inferior nasal, superior temporal and inferior temporal. Results: 130 eyes of 130 patients were included; 121 were male and 9 female, with an age rank of 6 months to 69 years (average 32.4). The most common affected zones were central (35.4%), inferior temporal (29.2%), inferior nasal (21.5%), superior nasal (9.2%) and supe-rior temporal (4.5%). Peripheral disease comprised (64.6%) of the series. Discussion: Almost two thirds of corneal superficial foreign bodies were localized out-side the central area. This features make their withdrawal, by means of gentle manoeuvres, a safe tool for primary care physicians, before thorough ophthalmic evaluation and therapy are instituted.
