结膜异物
English: Conjunctival Foreign Body, Ocular Foreign Body
中文: 睫毛、沙尘等细小物体进入结膜囊。藏在上睑内侧时,可偶尔蹭一下角膜后移位,痛感瞬间消失;不一定每次眨眼都诱发。翻睑与染色有助于确诊。
English: A lash, grit, or particle in the conjunctival sac. Under the upper lid it may scrape the cornea once then shift—pain gone in a second. Lid eversion and fluorescein help confirm.
