To evaluate the final visual outcome and various factors affecting the prognosis in cases of IOFB and to study the epidemiological profile of patients and morphological characteristics of IOFB.
Prospective analysis of 62 patients with IOFB carried out at Nagri Eye Research Foundation, Ahmedabad.
All the patients with history of injury and intraocular IOFB from August, 2011 to August 2013 were included in the study. Detailed history taking and clinical examination were done in all the patients followed by necessary investigations. Necessary parameters are recorded including time of presentation, time of intervention, mode of injury, site of entry, type and size of IOFB, location, type of surgery, tamponade used and associated complications. Surgery was performed in all the cases depending on associated condition and IOFB was removed. All the patients were followed up for 6 months after the surgery.
83.8 % patients were male and 80% of all patients were less than 40 years of age. 75 % of the patients were presented within 1 week of injury. 60 % of the injury occurred during hammering. Corneal entry wound was found in 83.87 % of the patients. In 64.51 % of the cases wound was sealed. Cataractous changes due to foreign body were noted in 70% of the cases. In 83.88 % of eyes, foreign body was noted in posterior segment. There was significant difference in improvement of visual acuity in patients who underwent early surgery (less than 2 weeks). Retinal detachment and proliferative vitreoretinopathy were most common causes for decreased visual acuity. The larger size of IOFB was associated with poor prognosis. Mode of entry, type of IOFB and location of IOFB were not significant predictive factors for prognosis.
IOFB is one of leading causes of visual impairment in young male patients working in metal industry. Early intervention with pars plana vitrectomy significantly improves the visual acuity.
