Methods:Twelve patients (7 males and 5 females, aged 5 to 56 years).with plant foreign bodies embedded in the deep cornea were treated between July 2011 and December 2012. The course of disease ranged from 1 to 11 d. Four of the patients had wooden foreign bodies, 3 had bamboo foreign bodies, and 5 had flower thorns; all underwent surgical removal. During the surgery,a novel suture needle was used to remove the foreign bodies.For injuries with a deep tunnel caused by the foreign bodies,the tunnel was cut open with a keratome. The foreign bodies were then removed and necrotic tissue was thoroughly debrided.Incisions were closed with interrupted sutures. The corneal foreign bodies were collected postoperatively for fungus and bacterial culture and appropriatemedical treatment was provided. Results: Bacteria were identified in 3 cases, fungus in 3 cases, and no bacteria or fungus in 6 cases.All corneal foreign bodies were embedded deep in the corneal stroma without incidence of full-thickness corneal penetration or intraocular infection. Conclusion:Plant foreign bodies embedded in the deep cornea should be removed immediately. During the surgery, the foreign bodies and surrounding necrotic corneal stroma should be completely removed. The injured cornea should be cut open to eliminate necrotic tissues when necessary. (Eye Science 2013; 28:30-33)展开更多

A pigmented lesion with anterior chamber inflammation was noted on examination. B-scan ultrasound was performed and revealed no foreign body. The patient was diagnosed with anterior uveitis, which did not completely respond to treatment. The differential diagnosis was expanded to include peripheral ulcerative keratitis, phlyctenulosis, pigmented neoplasm, and corneal foreign body. Upon referral to a cornea specialist, an exam under anesthesia revealed a large foreign body consistent with a rock fragment in the peripheral cornea, which was subsequently removed without complication. Conclusion: This case highlights an atypical presentation of foreign body as well as a differential diagnosis of pigmented peripheral corneal lesions. Foreign bodies represent the most common cause of urgent ophthalmic evaluation. When evaluating lesions of the cornea, it is imperative to keep an extensive differential diagnosis, giving the potential for severe and rapid development of visually threatening complications.展开更多
