Abstract

To determine the influence of prognostic factors on the visual outcome in patients who underwent vitrectomy for intraocular foreign body.A retrospective study was conducted at the Ophthalmology Department, Lahore General Hospital Lahore, between 2017 and 2021. A sample size of 60 patients is estimated by using a 95% confidence level, 7% absolute precision with an expected percentage of 8.4 %. The data of 62 patients who aged between 25 to 55 years and presented with open-globe injuries and retained IOFBs was collected by non probability purposive sampling technique.All the patients underwent 23-gauge pars plana vitrectomy with removal of IOFB. The final BCVA was improved by 02 letters or more on Snellen’s acuity chart in 38 (61.29%) patients and remained the same in 21 (33.87%) eyes while in 03 (4.84%) cases it decreased. Despite the systemic antibiotics, 03 (4.83%) eyes ended up with endophthalmitis. None of the eyes were enucleated.The prognosis of an IOFB injury is mostly uncertain due to a complex combination of parameters. The main prognostic factors related to better visual outcomes were initial BCVA, time to surgery (first week), initially attached retina and the scleral entry site. Prognostic factors for poor final VA related to IOFBs included poor initial VA, large IOFB size, posterior segment location, and preoperative retinal detachment. The main complication was endophthalmitis.
