Fluorescein staining is helpful in diagnosis. Many conjunctival foreign bodies can be removed by swab or irrigation, without anesthesia. Cycloplegics can prevent painful ciliary spasm. A surgical opening may be required for deeply embedded objects. Topical anesthesia is required for corneal foreign body removal. Caution: x-rays must be made to rule out intraocular foreign bodies in cases of flying metal. Rust rings must be removed. Mydriatics or cycloplegics can precipitate glaucoma. Corneal abrasions are easily infected. Secondary iritis may follow deeply embedded foreign bodies.
荧光素染色有助于诊断。许多结膜异物可用棉签或冲洗去除，无需麻醉。睫状肌麻痹剂可预防疼痛性睫状肌痉挛。对于深埋的异物可能需要手术切开。取出角膜异物需要局部麻醉。注意：对于金属飞溅伤病例，必须进行X线检查以排除眼内异物。锈环必须清除。散瞳剂或睫状肌麻痹剂可诱发青光眼。角膜擦伤容易感染。深埋的异物可能继发虹膜炎。
