Clinical assessment of 25G micro-incision vitrectomy for treatment of intraocular foreign bodies / 眼科新进展

ABSTRACT

Objective To investigate the clinical efficacy of 25G minimally invasive vitrectomy for the removal of foreign bodies in the posterior segment of the ball.Methods The clinical data of 21 patients (21 eyes) with intraocular foreign bodies who underwent 25G minimally invasive vitrectomy combined with intrabulbar foreign body removal were retrospectively analyzed,including magnetic foreign bodies in 17 patients and non-magnetic foreign bodies in 4 patients.All the patients had cataract and vitreous hemorrhage,with 3 patients (3 eyes) suffering secondary endophthalmitis,and 12 patients (12 eyes) suffering secondary retinal detachment.Cataract extraction,retinal reattachment and silicone oil tamponade were combined according to different conditions,and the complications and surgical outcomes were analyzed for 6-month followup.Results All patients received preoperative examinations,immediately following implementation of 25G minimally invasive vitrectomy and intrabulbar foreign body removal procedures.The removal rate of foreign bodies in phase Ⅰ was 100％.All the endophthalmitis and retinal detachment were cured before operation.The turbid lens was removed during operation from the corneal incision in 20 patients (20 eyes),and from a scleral incision in 1 patient after cataract extraction.A total of 19 eyes had better postoperative visual acuity than preoperative vision,14 eyes underwent phase Ⅱ intraocular lens implantation,and silicone oil was retained in 2 eyes.No postoperative complications related to minimally invasive surgery occurred.Conclusion 25G minimally invasive vitrectomy has good clinical outcomes in the removal of intraocular foreign bodies in the posterior segment of the eye,with minimal surgical trauma,rapid visual function recovery,and fewer complications,but great attention should be paid to its indications.
