Abstract

INTRODUCTION: INTRA-CORNEAL FOREIGN BODIES ARE A COMMON OCCURRENCE IN THE PRIMARY EYE CARE SETTING. THE MOMENTUM (MASS X VELOCITY) OF A FOREIGN BODY IS THE PRIMARY DETERMINANT OF THE DAMAGE THE FOREIGN BODY WILL CAUSE AND THE DEPTH TO WHICH IT WILL PENETRATE I.E. EPITHELIUM TO BOWMAN’S MEMBRANE ,BUT NOT SUFFICIENT MOMENTUM TO ENTER THE ANTERIOR CHAMBER. THE UNIQUE PHYSICAL AND PHYSIOLOGICAL PROPERTIES OF THE CORNEA, AND THE TOXICITY AND REACTIVITY OF DIFFERENT TYPES PROVIDES MULTIPLE TREATMENT OPTIONS FOR A RETAINED FOREIGN BODY.

METHOD: THE FOLLOWING VIDEO DEMONSTRATES THE FOREIGN BODY AT DIFFERENT LEVELS OF DEPTH AND THE WAY IT HAS BEEN MANAGED ACCORDINGLY.

CONCLUSIONS: UNDERSTANDING THE CIRCUMSTANCES IN WHICH AN INJURY OCCURS AND THE COMPOSITION OF THE FOREIGN BODY HELPS TO DIRECT THE CLINICIAN’S DIAGNOSTIC AND TREATMENT DECISIONS. PAIN IS NOT ALWAYS A RELIABLE INDICATOR OF THE SEVERITY OF AN INJURY AS DEMONSTRATED BY THIS PATIENT’S DELAY IN SEEKING TREATMENT.
