Outcomes and prognostic factors of 25G minimally invasive vitrectomy for intraocular foreign body

Abstract

AIM:To explore clinical characteristics, outcomes and prognostic factors for cases with intraocular foreign bodies(IFB)and treated with 25G minimally invasive vitrectomy(PPV).METHODS: Patients traumatized with retained IFB and treated with PPV were retrospectively collected from the Department of Ophthalmology, Affiliated Hospital of Southwest Medical University from 2016-1-1 to 2019-1-1. The clinical records including general condition, time and cause of injury, locations andsize of IFBs, comorbidities, and best corrected visual acuity(BCVA)were reviewed and statistical analyzed.RESULTS: Among the 105 patients, most of them are middle-aged and young men, mostly from townships. The nature of IFB was mainly metals(62 cases, 59.0%). The entrance of IFB of 78 cases(74.3%)located at Zone I of the eye. There were 17 patients with BCVA≥0.1 before surgery, 88 patients with BCVAPCONCLUSION: PPV for treatment of IFB can achieve a better outcome. The poor prognosis of visual acuity is related to retinal detachment, endophthalmitis, and the position and size of IFB.
