“…Metal, obviously associated with hammering or Predictive factors and outcomes of IOFBs J Choovuthayakorn et al chiseling, was the most common nature of IOFBs, which is similar to other studies. [11][12][13] Interestingly, this study also revealed that the electric grass trimmer was the most common mechanism of injury. Poor presenting VA has previously been reported as an important predictive factor for poor visual outcomes.…”

“…As our medical center is a tertiary referral center, the mean time of IOFBs removal in this study was 30.7 days (median 6 days), whereas the incidence of endophthalmitis was 9.1%, which is comparable to other studies; range 0-20%. [11][12][13]16 In a preceding report, certain different physical characteristics of magnetic and nonmagnetic IOFBs were associated with a higher rate of retinal break formation and subsequent RD, especially with glass IOFBs. 18 This study did not demonstrate a correlation between the nature of IOFBs and postoperative RD (Fisher exact test, P ¼ 1.000).…”

Purpose To identify the predictive factors for anatomical and visual outcomes in posterior segment intraocular foreign body (IOFB) patients managed by pars plana vitrectomy (PPV). Methods A retrospective chart review was performed for 77 patients, who had PPV for IOFBs removal between January 2001 and July 2007. Univariate and multivariate analyses were conducted to evaluate the predictive factors.Results The mean age of the patients was 33.4 years. The nature of IOFBs was mainly metal, with injuries most commonly caused by an electric grass trimmer. The mean time interval between injury and IOFBs removal was 30.7 days. The mean preoperative visual acuity (VA) was 1.82 logarithm of the minimal angle of resolution (logMAR), and mean final was VA 1.10 logMAR. From multivariate analysis, good visual outcome was correlated with the corneoscleral entry site, and poor visual outcome was correlated with the presence of relative afferent pupillary defect. Conclusions In noncombat IOFBs, most cases were work-related. Delayed IOFBs removal was acceptable when primary wounds were repaired appropriately and extensive antibiotics administered. Even though advancement in vitreoretinal surgery can reduce the frequency of blindness, further promotion and education on eye protection during work are needed.

“…The decision to administer intravitreal antibiotics should be considered in high-risk setting. 7,8 Consequently, the acceptable endophthalmitis rate of 9.1% in this study may depend on domestic type of injury and prophylactic systemic antibiotic application with no intravitreal antibiotic injections. However, the definite role of giving intravitreal antibiotic prophylaxis in eyes suffering from different types of IOFB had not been explored in this limited data study.…”

“…They must be excluded in all cases of ocular blast injury. The final resting place of and damage caused by an IOFB depends on the size, the shape and the momentum of the object at the time of impact, and the site of ocular penetration [45]. In modern warfare a large proportion of IOFBs treated are from grit and stones thrown up by explosions, they are frequently multiple.…”

Eye injuries come at a high cost to society and are avoidable. Ocular blast injuries can be primary, from the blast wave itself; secondary, from fragments carried by the blast wind; tertiary; due to structural collapse or being thrown against a fixed object; or quaternary, from burns and indirect injuries. Ballistic eye protection significantly reduces the incidence of eye injuries and should be encouraged from an early stage in Military training. Management of an injured eye requires meticulous history taking, evaluation of vision that measures the acuity and if there is a relative pupillary defect as well as careful inspection of the eyes, under anaesthetic if necessary. A lateral canthotomy with cantholysis should be performed immediately if there is a sight-threatening retrobulbar haemorrhage. Systemic antibiotics should be prescribed if there is a suspected penetrating or perforating injury. A ruptured globe should be protected by an eye shield. Primary repair of ruptured globes should be performed in a timely fashion. Secondary procedures will often be required at a later date to achieve sight preservation. A poor initial visual acuity is not a guarantee of a poor final result. The final result can be predicted after approximately 3-4 weeks. Future research in eye injuries attempts to reduce scarring and neuronal damage as well as to promote photoreceptor rescue, using posttranscriptional inhibition of cell death pathways and vaccination to promote neural recovery. Where the sight has been lost sensory substitution of a picture from a spectacle mounted video camera to the touch receptors of the tongue can be used to achieve appreciation of the outside world.
