摘　　要：1例61岁右眼视物不清1 d男性患者,曾行右眼超声乳化白内障吸除人工晶状体(IOL)植入术(10年前)和右眼地塞米松玻璃体腔植入剂治疗(因葡萄膜炎)。右眼角膜下方雾状水肿,后弹力层皱褶,前房下方可见地塞米松玻璃体腔植入剂药棒。未散瞳、平卧位、避免低头1 d,地塞米松玻璃体腔植入剂药棒自行还纳于玻璃体腔,角膜水肿较前减轻。考虑可能是因局部晶状体悬韧带异常,导致地塞米松玻璃体腔植入剂药棒异位于前房。A 61-year-old male patient presented with blurred vision in the right eye for 1 day.The patient had previously undergone phacoemulsification with intraocular lens implantation(10 years ago)and intravitreal implantation of dexamethasone(due to uveitis)in the eye.There was edema in the inferior cornea,along with Descemet membrane folds.The rod-shaped dexamethasone implant was visible in the inferior anterior chamber.Without pupil dilation,the patient was asked to keep a supine position and avoid head tilting for 1 day.The implant spontaneously relocated into the vitreous cavity,resulting in a reduction of corneal edema.This suggests that the dislocation of the intravitreal implant into the anterior chamber may be caused by a local zonular abnormality,and the dislocated implant has the potential to reposition itself spontaneously.
