Of 50 patients attending the eye casualty department with a corneal foreign body (FB), 41 were able to say where they felt the FB and 78% of these were localised correctly for side or level of cornea. Patient handedness did not influence FB location. Indicating the upper lid was a particularly poor guide to localisation, whereas FB sensations within the palpebral fissure, in the lower lid or medially or laterally were good guides to actual FB location. A simple method of recording FB location by zone and clock hour is proposed.
在50名因角膜异物（FB）前往眼科急诊的患者中，41名能够说出他们感觉异物所在的位置，其中78%的异物在角膜的侧面或层面定位正确。患者的利手并不影响异物的位置。指出上睑对定位来说是一个特别差的指引，而睑裂内、下睑或内侧或外侧的异物感是实际异物位置的良好指引。本文提出了一种通过区域和钟点记录异物位置的简单方法。
