“…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.

“…Regardless of the nature of the FB, the presenting ophthalmic disease is highly variable, depending on the interval between trauma and presentation, degree of anterior and/or posterior segment penetration and retention, or loss of the FB [13][14][15][16]. Managing options depend on clinical presentation and range from conservative medical treatment to surgery to remove the FB and/or address concurrent ocular injuries [17][18][19][20][21].…”

Penetrating palpebral grass awn in a dog

et al. 2017

An unusual case of a penetrating grass awn in an eyelid of a dog is reported. A 6-month-old mixed breed dog was referred to the Ophthalmology Unit of the Veterinary Teaching Hospital of Camerino University for anorexia, lethargy, left monolateral ocular swelling and pain to the left eye, present from 1 month. Ophthalmic examination of the left eye showed copious and purulent discharge, and ultrasonography revealed the presence of an abscess containing a grass foreign body. The grass awn was surgically removed. Three days after surgery, the dog showed a marked improvement, with a total resolution obtained in 7 days. To the authors' knowledge, penetrating foreign bodies such as the one of this paper have never been described before in literature.Keywords Dog Á Foreign body Á Grass awn Á Lid abscess Á Swollen eyelid Á Ultrasonography Riassunto Questo articolo descrive un particolare caso di corpo estraneo palpebrale di origine vegetale Un cane meticcio di sei mesi di età è stato riferito all'Unità di Oftalmologia dell'Ospedale Veterinario Didattico dell'Università di Camerino per la presenza di anoressia letargia e tumefazione oculare monolaterale sinistra associata a dolore presenti da un mese. L'esame oftalmologico dell'occhio sinistro ha messo in evidenza la presenza di abbondante essudato purulento e la valutazione ultrasonografica ha mostrato la presenza a livello palpebrale di un ascesso contenente un corpo estraneo vegetale che è stato rimosso chirurgicamente. Tre giorni dopo la chirurgia il cane già manifestava un marcato miglioramento con una guarigione completa dopo una settimana. In bibliografia non sono stati mai descritti corpi estranei vegetali penetranti a livello palpebrale come quello riportato nel presente articolo.

“…2 In such cases, the ophthalmic examination should begin with the documentation of visual acuity, followed by a detailed examination of the orbit for periorbital and subconjunctival hemorrhage and proptosis. Extraocular movements and visual fields should be examined and a careful inspection of the globe should be performed to determine the presence or absence of perforation.…”

Craniomaxillofacial Trauma & Reconstruction

High-velocity injuries, such as those that stemming from a gunshot or industrial accident, can lead to the occurrence of an intraorbital foreign body, 1 often accompanied by penetrating ocular trauma. 2 In such cases, the ophthalmic examination should begin with the documentation of visual acuity, followed by a detailed examination of the orbit for periorbital and subconjunctival hemorrhage and proptosis. Extraocular movements and visual fields should be examined and a careful inspection of the globe should be performed to determine the presence or absence of perforation. 3 With advances in radiological techniques, such as high-resolution reconstruction computed tomography, the assessment of such injuries has become easier and more accurate. 4 The retrieval of an intraorbital foreign body can be difficult because of the proximity of critical structures, such as the contents of the superior orbital fissure, the optic nerve, ethmoidal vessels, and cranial structures. 5 Among the different approaches employed in the treatment of facial injuries, the coronal approach, which was popularized by Tessier, is one of the most versatile for midface surgeries. 6 However, the large incision causes concern regarding the visible postoperative scar. Thus, several techniques have been described to minimize scar visibility, including a straight incision, coronal incisions, a gull-wing or W-shaped incision, and the use of six short linear incisions. 7 This article describes the use of the temporal approach on a firearm victim in whom the breech of a rifle had impaled orbital region, with the extremity lodged in the infratemporal fossa. Case ReportA 31-year-old male patient presented to the Regional Trauma Hospital in Campina Grande (state of Paraíba, Brazil) following an accident with the breech of a rifle, which had Keywords ► intraorbital foreign body ► orbit ► temporal AbstractAccidents with firearms can result in extensive orbital trauma. Moreover, gun parts can come loose and impale the maxillofacial region. These injuries can cause the loss of visual acuity and impair eye movements. Multidisciplinary treatment is required for injuries associated with this type of trauma. Computed tomography with threedimensional reconstruction is useful for determining the precise location and size of the object lodged in the facial skeleton, thereby facilitating the planning of the correct surgical approach. The temporal approach is a fast, simple technique with few complications that is indicated for access to the infratemporal fossa. This article describes the use of the temporal approach on a firearm victim in whom the breech of a rifle had impaled orbital region, with the extremity lodged in the infratemporal fossa.
