“…This distribution of visual outcome is very similar to previous studies of anterior and posterior segment IOFB, with the majority (61-71%) of patients maintaining good visual acuity (6/12 or better) but a significant minority (17-38%) sustaining severe loss of vision (worse than 6/60). 5,8,11 If bestcorrected vision has been measured with a pinhole, or with a correcting lens that the patient does not routinely wear, day-to-day functional vision is often poorer than best-corrected vision. This is particularly true for aphakic eyes and those filled with silicone oil.…”

“…[1][2][3][4] IOFBs frequently cause severe visual loss, with 17-42% resulting in final vision worse than 6/60 in the injured eye. [3][4][5][6][7][8] A high percentage (50-54%) of IOFBs were identified as arising from work-related injuries, 3,6,9 and regardless of the environment in which the injury occurred, hammering was the most common mechanism of injury, accounting for 71-80% of such injuries. 7,[10][11][12] In one large American study, only 6% of persons with IOFBs were wearing protective eyewear.…”

Aims To estimate the incidence of penetrating injuries with retained intraocular foreign bodies (IOFBs) in the United Kingdom, and to provide epidemiological data on the aetiology, management, and visual outcome of such injuries. Methods Cases were identified prospectively by active surveillance through the British Ophthalmological Surveillance Unit reporting card system, for the 12-month period June 2004 to May 2005 inclusive. Questionnaire data were obtained from UK ophthalmologists at presentation and 6 months following presentation. Results Data were available on 97 patients at presentation and 95 patients at follow-up. The minimum estimated incidence of IOFBs in the United Kingdom identified in this study was 0.16 per 100 000. All patients were male. Hammering was the most common mechanism of injury, occurring in 62% of patients. The IOFB was found in the anterior segment in 24%, the posterior segment in 73%, and involved both segments in 3%. Endophthalmitis was diagnosed in 9% of patients. Best-corrected visual acuity of the injured eye at final follow-up was 6/12 or better in 67%, 6/18 to 6/60 in 11%, and worse than 6/60 in 22%. Prognostic factors for a poor visual outcome included poor visual acuity at presentation, prolapse of intraocular tissue, development of endophthalmitis, development of retinal detachment, and large size of IOFB. Conclusions The incidence of IOFB in the United Kingdom appears to have reduced compared to previous studies. The majority of patients (67%) retain good visual acuity in the injured eye; however, a significant minority (22%) sustain long-term severe visual loss.

“…1 Intraocular foreign bodies have received a great deal of attention by Ophthalmologists over the past three decades. 2 Toxicity of intraocular foreign body is variable. Metallic ion poisoning of intraocular epithelial structures is seen with copper, iron, lead, zinc and nickel.…”

“…Most intraocular foreign bodies are metallic and magnetic. 2,6 Magnetic removal of ferrous intraocular foreign body has been used for more than 100 years, but it has been criticized lately for causing more complications in comparison to vitrectomy. However, it still has a place in treating selected cases.…”

A young man working in a workshop sustained penetrating injury to his left eye and reported within 12 hours to Eye Hospital. Plain X-ray orbit confirmed the presence of intraocular foreign body near pars plana. Corneal wound of entry was repaired with 10/0 suture. The intraocular foreign body was removed by magnet through trans scleral magnet via pars plana approach without 3 port vitrectomy procedure. Mild traumatic endophthalmitis was controlled by intravitreal injection of Vancomycin 1mg/0.1ml, along with topical antibiotic and steroid therapy. After 6 weeks, extraction of soft traumatic cataract and posterior chamber lens implantation was done. Best-corrected vision of 6/12 was achieved.

“…A vegetative FB such as wood may reach inner part of eye but is located usually in the anterior segment [3,4]. Animal matter such as cilia can be carried along with denser matter to the posterior segment [1,2,5]. Ocular damage caused by intraocular foreign bodies (IOFB) can occur by two mechanisms; (1) penetrating injury with its secondary complications and (2) by the presence of IOFB itself causing damage from microbial endophthalmitis, toxicity and other inflammatory reactions [4,6,7].…”

Submit Manuscript | http://medcraveonline.com posterior segment FBs is derived from metal fragments. A vegetative FB such as wood may reach inner part of eye but is located usually in the anterior segment [3,4]. Animal matter such as cilia can be carried along with denser matter to the posterior segment [1,2,5]. Ocular damage caused by intraocular foreign bodies (IOFB) can occur by two mechanisms; (1) penetrating injury with its secondary complications and (2) by the presence of IOFB itself causing damage from microbial endophthalmitis, toxicity and other inflammatory reactions [4,6,7]. Pathological evaluation of various FB in the eye and adnexa can give us bunch of information about the damages to the structures. Aim:To study pathological significance of ophthalmic FB in a referral tertiary institute of north-east India. Materials and MethodsThis is a hospital based, retrospective, laboratory study conducted in a tertiary ophthalmic institute of north-east India between 2010 to 2015. Different tissues including eyeball specimens received in ocular pathology laboratory were studied in details. Gross examinations were carried out in the (LEICA S6D) dissection microscope and were documented. Histopathological analysis was carried out with Hematoxylin and Eosin (H&E) stain, other special stains and polarizer were used in (ZEISS) microscope Axioskop 40 and documented in (AxioCamMRc) camera. Specialized stains included Perl's stain for iron body, tissue Grams's stain (GIS) for microorganisms, Grocott's methenamine silver stain (GMS) for fungus, periodic acid schiff stain (PAS) for fungus and basement membrane of different structures, Congo red for amyloid to see ancillary pathologies. Sixteen pathological specimens with various FBs were seen and classified. Further hospital records were reviewed for the clinical profile, and other ancillary investigations to correlate the findings. ResultsSix cases of iron FB s were seen and acknowledged. One case of copper FB was seen in intraocular specimen with phthisical blind eye which was confirmed by scanning electron microscopy (SEM) (Figure 1a) and Energy dispersive X-ray spectroscopy (EDX) (Figure 1b). Three cases of vegetative FB were seen in the orbital/lid tissues (Figure 2). FBs were detected in pathological specimen of two sympathetic ophthalmia cases (Figure 3). Urate crystals were documented in one of the conjunctival specimen. (Figure 4a). One case of tripod glass wool FB (Mercedes Benz sign) was documented in a conjunctival specimen (Figure 4b). A case of insect body in the tissue (Figure 4c,d,e) and other case of cilia was detected in the cohort. All iron FB were identified and measured. Out of six iron FBs, four had positivity with Perl's stain in the tissue sections. One iron FB had changes in the lens and its surrounding in a phthisical enucleated eyeball. One out of the three cases of vegetative FB had associated fungal infection (Aspergillus). Results of all FBs are shown in Figure 5. DiscussionManagement of eye trauma is of concern to both the beginner ophth...
