Recovery of Vision in Open Globe Injury Patients with Initial No Light Perception Vision.

PURPOSE: To identify clinical characteristics of injured eyes associated with visual recovery in patients with open globe injuries (OGIs) and presenting with no light perception (NLP) vision. DESIGN: Retrospective chart review. SUBJECTS: All patients presenting to Massachusetts Eye and Ear with OGI and NLP vision from January 1999 to March 2022. METHODS: Manual data extraction to collect patient demographic characteristics, preoperative, intraoperative, and postoperative characteristics of OGI injury, laceration versus rupture, history of intraocular surgery, time from injury to repair, timing of vitrectomy, lensectomy, choroidal drainage, and silicone oil placement, visual acuity (VA) at last follow-up, and subsequent B-scan ultrasound findings of retinal detachment, choroidal hemorrhage, vitreous hemorrhage, and disorganized intraocular contents. Patients with >1 week of follow-up and a documented VA at most recent follow-up were included. Exclusion criteria included age <10 years. Multivariable regression was performed. MAIN OUTCOME MEASURES: Visual acuity recovery defined as light perception or better in patients with OGI and initial NLP vision. RESULTS: One hundred forty-seven eyes with NLP vision after OGI were included. Twenty-five (17%) eyes regained vision at last follow-up. The majority of patients recovered light perception vision (n = 15, 60%) followed by 20/500 or better (n = 5, 20%), hand motions (n = 3, 12%), and counting fingers (n = 2, 8%). Most injuries were zone III (n = 102, 69%) and presented with rupture (n = 127, 86%). The mean time from OGI to surgical repair was 0.85 ± 1.7 days. B-scan was obtained in 104 (71%) cases. Pars plana vitrectomy was performed in 9 eyes (6%) with NLP at time of vitrectomy. Disorganized intraocular contents on B-scan (odd ratio, 0.170; 95% confidence interval, 0.042-0.681; P = 0.012) was the only clinical variable significantly associated with visual recovery, corresponding to a lack of visual improvement. CONCLUSIONS: Recovery of vision in OGI with NLP vision at presentation cannot be predicted based on presenting clinical features. B-scan findings of disorganized intraocular contents after initial OGI repair was the only factor negatively associated with vision recovery in this patient population. Therefore, all eyes presenting with an OGI and NLP vision should undergo primary repair in hopes of subsequent visual recovery.

Visual outcomes and prognostic factors of early pars plana vitrectomy for open globe injury.

OBJECTIVES: To identify the clinical features and outcomes of early vitrectomy in patients with open globe injury (OGI) and the prognostic factors for visual outcome. METHODS: This retrospective observational case series included 390 eyes in 389 patients diagnosed with OGI receiving vitrectomy within four days after injury. Preoperative parameters included the injury types, wound locations, consequent tissue damages, initial visual acuity (VA), and ocular trauma score. Postoperative outcome measures included surgical procedures, retinal (re)attachment, complications, and final VA. The logistic analysis evaluated the prognostic factors for visual outcome. RESULTS: Intraocular foreign bodies (59.2%) and penetrating injuries (28.7%) were the most common injury types. Among the 165 eyes with retinal detachment (RD), 121 (73.3%) had retinal reattachment during early primary vitrectomy, and 32 (19.4%) were repaired during a second or subsequent surgery. Thirteen eyes (3.3%) were enucleated. The final VA improved from the initial level in 207 eyes (55.2%), remained unchanged in 123 (32.8%), and decreased in 45 (12.0%). Multivariable regression revealed that the injury zone, initial VA, RD, and endophthalmitis were associated with poor visual outcomes (P < 0.05). CONCLUSIONS: Higher zone injury, low initial VA, RD, and endophthalmitis are predictors of poor visual outcome in eyes undergoing early vitrectomy for OGI.

SILICONE OIL-FILLED FOLDABLE CAPSULAR VITREOUS BODY VERSUS SILICONE OIL ENDOTAMPONADE FOR TREATMENT OF NO LIGHT PERCEPTION AFTER SEVERE OCULAR TRAUMA.

PURPOSE: To compare the anatomical and functional outcomes of silicone oil (SO)-filled foldable capsular vitreous body (FCVB) and SO endotamponade in vitrectomy for patients with no light perception after ocular trauma. METHODS: A total of 64 patients (64 eyes) with no light perception caused by severe ocular trauma were divided into FCVB and SO groups based on the surgical treatment. The main outcome measurements were retinal reattachment rate, intraocular pressure, best-corrected visual acuity, and number of operations. RESULTS: Both the FCVB group (29 eyes) and the SO group (35 eyes) showed significant improvement in postoperative best-corrected visual acuity and intraocular pressure. The two groups showed no significant differences in final intraocular pressure and the retinal reattachment rate. The postoperative vision (≥LP) in the FCVB group was significantly worse than in the SO group (FCVB [4/29] vs. SO [18/35], P = 0.003). However, the number of surgeries in the FCVB group was significantly lower than in the SO group (FCVB [1.10] vs. SO [2.23], P < 0.001). CONCLUSION: Vitrectomy combined with SO endotamponade shows better short-term improvement in the treatment of no light perception caused by severe ocular trauma. However, SO-filled FCVB can effectively prevent many complications caused by direct SO endotamponade, such as secondary surgeries or SO dependence.

Open-globe wounds in operation Iraqi Freedom and Operation Enduring Freedom: risk factors for poor visual outcomes and enucleation.

PURPOSE: To determine the rates and types of open-globe wounds in soldiers admitted to Walter Reed Army Medical Center from 2001 to 2011 after sustaining combat injuries. METHODS: Data were collected in the Walter Reed Ocular Trauma Database. Inclusion criteria were patients who suffered open-globe injuries. Open-globe injuries were classified by type of wound: corneal, corneo-scleral or scleral, or type of open-globe injury: perforating, rupture, penetrating or intraocular foreign body. The primary analysis assessed the effect on final visual acuity (VA) and the risk of enucleation. RESULTS: In this study, 285 (32.02%) open-globe injuries were recorded in 890 eyes in the data set. Corneal wounds were noted in 127 (44.56%) eyes, corneo-scleral wounds in 78 (27.37%) and scleral wounds in 129 (45.26%) eyes. The involvement of both the corneal and sclera was associated with poorer visual outcome (BCVA < 20/200) compared to injuries with an injury confined to either the cornea or scleral alone (p = 0.038). At a wound length of greater than approximately 14 mm, patients had 75% chance of having a poor final VA. Enucleation was performed in 64 (22.46%) eyes of patients with wounds. The type of wound was not found to be predictive of enucleation in multivariate analysis, but rather the type of open-globe injury was predictive. Perforating (OR: 1.58, 95% CI: 1.43-1.72) and globe rupture injuries (OR: 1.49, 95% CI: 1.33-1.66) were more likely to undergo enucleation. CONCLUSIONS: Open-globe injuries occur frequently in combat ocular trauma. Poor final VA was noted most with corneo-scleral wounds with approximately 50% of patients having a final VA less than 20/200.

Poor prognoses of open globe injuries with concomitant orbital fractures.

PURPOSE: Orbital trauma, particularly with open globe injury, can have a wide range of visual outcomes, which can be difficult to predict at presentation. Clinical features on presentation may provide insight into visual prognosis. We hypothesized that patients with open globe injuries and concomitant orbital fractures have poorer visual outcomes than patients without orbital fractures. METHODS: We reviewed the charts of 77 patients with isolated open globe injuries (OG) and 76 patients with open globe injuries and concomitant orbital fractures (OGOF). Multivariate regression analysis was performed to assess the relative influence of individual presenting historical and clinical features on visual outcome. RESULTS: OGOF patients were more likely to have sustained blunt trauma than a sharp, penetrating injury compared to OG patients. Ocular wound locations were more posterior and likely to involve multiple zones in OGOF compared to OG patients. Among OGOF patients, orbital floor fractures were the most common and roof fractures were the least common, but the latter was associated with presenting NLP vision and multiple zone involvement. The presence of an orbital fracture independently increased the odds of subsequent evisceration/enucleation (OR: 4.6, 95% CI 1.3-20.1, p = .0246) and NLP vision (OR: 6.81, 95% CI 2.42-21.85, p = .0005) when controlling for zone, mechanism of injury, uveal prolapse and demographic variables. CONCLUSIONS: The presence of an orbital fracture independently confers a worse visual and ocular prognosis in patients with open globe injuries. Patients with open globe injuries in this category should be appropriately counseled.

Clinical Results in Patients with Combined Penetrating Keratoplasty and Vitreoretinal Surgery Using Landers Wide-field Temporary Keratoprosthesis

Objectives: To evaluate the clinical results of combined pars plana vitrectomy (PPV) with Landers wide-field temporary keratoprosthesis and penetrating keratoplasty (PK). Materials and Methods: From January 2016, traumatic eyes with coexisting corneal and vitreoretinal diseases that underwent combined keratoprosthesis/PPV/PK surgery were retrospectively evaluated. Demographic characteristics, visual acuity (VA), intraocular pressure (IOP) and clinical findings of the cornea, lens, and retina were recorded during the follow-up. Cases with clear corneal graft, attached retina, normotonic IOP, and improved or stable VA were considered successful. Results: Eight eyes were enrolled in the study. The mean follow-up time was 21.1±8.20 months. Surgery was performed a mean of 23 (10-40) days after trauma. Preoperative VA ranged from no light perception to counting fingers from 50 cm. Postoperatively, corneal graft was clear in 5 patients (62.5%) and retina was attached in 6 eyes (75%). Chronic hypotonia developed in 3 patients (37.5%). VA was unchanged in 3 patients and improved in 5 patients. A total of 5 cases (50%) were considered successful. Shorter interval between trauma and surgery was associated with higher likelihood of success (p=0.043). No significant difference was observed between the groups in terms of type or location of trauma (p=1; p=0.143). Conclusion: Although the functional results are not very satisfactory, the combined procedure provides a final opportunity for preserving remaining vision and anatomic reconstruction in eyes that will otherwise result in phthisis due to severe anterior and posterior segment pathologies.

Pattern of ocular injuries in Bangladesh and its surgical management at hospital setting: A retrospective study.

OBJECTIVE: To determine the pattern of ocular injuries and their surgical management.. Methods: The retrospective study was conducted at the Chittagong Eye Infirmary and Training Complex, Chittagong, Bangladesh, and comprised hospital data of patients with ocular injuries from October 1, 2016, to December 31, 2017. Information gathered related to type and cause of injuries, visual acuity, postoperative complications, follow-up visits, and outcome. SPSS version 22 was used for data analysis. Results: Of the total injuries, 370 (91%) were classified open globe and 36 (9%) as close globe. In terms of type of injury, 330 (81.4%) were penetrating, 30 (7.3%) ruptured globe, 29 (7.1%) lime burn and 17 (4.2%) injuries were traumatic hyphaema and chemical in nature. Open globe injuries were mostly found in subjects aged 18 years or below. Surgery was the main mode of management in 388 (95.5%) patients. Conclusion: Preventive measures along with high-quality management should receive priority for reducing monocular blindness.

Effect of time to primary repair on final visual outcome after open globe injury.

BACKGROUND/AIM: Historic data suggest that open globe injuries should be repaired within 12-24 hours to reduce the risk of endophthalmitis. However, endophthalmitis is uncommon when systemic antibiotic prophylaxis is given. It is not clear whether delayed primary repair impacts visual outcomes in other ways or what is the optimum time to repair. We aimed to examine the effect of time to primary repair on visual outcomes. METHODS: This is a retrospective comparative case series including all open globe injuries presenting to the Birmingham Midland Eye Centre between 1 January 2014 and 15 March 2016. Presenting features, mechanism of injury, visual acuity at 6-12 months and demographic data were examined. RESULTS: 56 open globe injuries were repaired, of which sufficient data for analysis were available on 52 cases. The mean time to primary repair was 1 day after injury (range 5 hours to 7 days). Final visual acuity at 6-12 months was related to the presenting visual acuity and the Ocular Trauma Score and to the time between injury and primary repair, with a reduction in predicted visual acuity of logarithm of the minimum angle of resolution of 0.37 for every 24 hours of delay (95% CI 0.14 to 0.6). DISCUSSION: Open globe injuries should be repaired promptly. Presenting visual acuity remains the strongest predictor of outcome; however, delay to primary repair also reduced final visual acuity, and any significant delay from injury to repair is likely to negatively impact final visual outcome.

TRAFFIC ACCIDENT-RELATED OPEN GLOBE INJURIES.

PURPOSE: To evaluate the clinical characteristics and visual outcomes of patients with traffic accident-related open globe injuries, and to examine preoperative factors influencing the visual prognosis after pars plana vitrectomy, as compared with common open globe injuries. METHODS: Patients with open globe injuries, who underwent pars plana vitrectomy, were identified. Patients' demographic and clinical data were entered into a computerized database for review and analysis; data included age, sex, initial visual acuity, duration between onset of injury and surgery, information about the type and cause of injury, wound location and length, presence of ocular complications, and final visual acuity. RESULTS: Of the 355 open globe injuries, 14 were sustained during a traffic-related accident; the average age was 50.4 years (range: 20-85) and most (78.6%) were men. Of these 14 patients, 9 (64.3%) presented with rupture and 5 (35.7%) with laceration. Injuries were caused while driving (6 eyes; 42.9%), riding a bicycle (5 eyes; 35.7%), involved in car accident while walking (2 eyes; 14.3%), and riding a motorbike (1 eye; 7.1%). Initial visual acuity was significantly related to final visual acuity (P = 0.003, R = 0.80). The final visual acuity in patients with traffic accident-related open globe injuries was significantly better than that of the total group (P = 0.01). CONCLUSION: Traffic accident-related open globe injuries had better visual outcomes than common open globe injuries. Visual outcomes in patients with traffic accident-related open globe injuries were related to the initial visual acuity. No eyes developed endophthalmitis in patients with traffic accident-related open globe injuries.

Visual outcomes of pediatric traumatic cataracts.

INTRODUCTION:: To report visual outcomes and risk factors of pediatric traumatic cataracts in a tertiary care referral center in northern India. METHODS:: We analyzed medical records of traumatic cataracts in the pediatric age group (1-15 years) operated for cataract surgery with or without posterior chamber intraocular lens implantation with or without primary posterior capsulotomy with anterior vitrectomy between 2004 and 2012. Causative agents, types of trauma, demographic factors, surgical interventions, complications, and visual acuity were recorded and compared among different groups. RESULTS:: A total of 147 children were documented to have undergone cataract surgery for traumatic cataract in the study period, male-to-female ratio being approximately 5:1. Mean age was 7.67 ± 3.30 years (range, 1-15 years). Type of primary insult was penetrating injury in 100 (68%) patients and blunt trauma in 47 (32%) patients. Mean interval between injury and cataract surgery in penetrating injury cases was 3.84 ± 7.05 months and in the blunt injury cases was 6.28 ± 11.13 months. Preoperatively, only 110 patients were cooperative for visual acuity. Out of them, none had vision better than 6/18 and only 21 patients (19.9%) had vision of ≥6/60. Visual acuity of 6/18 or better (was considered good visual outcome) was achieved by 87.9%, 97.3%, and 97.9% at 1, 6, and 36 months, postoperatively. Eyes which underwent primary posterior capsulotomy and anterior vitrectomy during cataract surgery showed statistically better visual outcome than those without it. CONCLUSION:: Phacoaspiration with posterior chamber intraocular lens implantation along with primary posterior capsulotomy and anterior vitrectomy and timely introduction of amblyopia therapy helped in gaining good visual outcome in pediatric traumatic cataract patients irrespective of the age of presentation and the type of injury.

Initiation of fibrosis in the integrin Αvß6 knockout mice.

We previously demonstrated that ß6 knockout mice showed impaired wound repair in corneal debridement and keratectomy wounds. In the current investigation, we continued our examination of integrin αvß6 in order to determine if it was required for the initiation of wound healing in a corneal wound model that normally heals in a fibrotic manner. A full-thickness corneal incision was made in C57BL/6 J wild type (WT) and C57BL/6-Itgb6 KO (ß6-/-) mice. The mice were observed at 3, 7, 14, and 28 days post-incision. The morphology of corneal restoration was observed in tissue sections stained with hemotoxilin and eosin (H&E). In addition, indirect-immunofluorescence (IF) was performed on sections and/or whole mounts to evaluate the immunolocalization of α-smooth muscle actin (SMA) and thrombospondin-1 (TSP-1). H&E staining revealed that the corneas in ß6-/- mice healed slower than those in WT mice, with an obvious delay in the restoration of the stromal matrix and epithelium. In sections at 3 and 7 days, SMA and TSP-1 were greatly reduced in the ß6-/- mice as compared to WT, but peaked at 28 days after incision. Whole mount SMA IF results were consistent with those from sections. Therefore, the initiation of fibrosis was inhibited by the lack of αvß6; however, there appeared to be an alternate mechanism that initiated fibrosis 7-14 days later. Localization of TSP-1 correlated with expression of SMA whether wound healing was delayed or initiated immediately after wounding.

Prognostic factors for open-globe injuries: variables for poor visual outcome.

PURPOSE: To determine prognostic factors for open-globe Injuries (OGI). METHODS: Open-globe injuries referred to a tertiary referral clinic in Turkey between January 1998 and January 2016 were retrospectively analyzed. Univariate and multivariate logistic regression analyses were conducted to find out the most important variables for poor visual outcome. RESULTS: Six hundred and thirty-three patients were studied with an average age of 24.37 ± 11.1 years (range 1-80).The male/female ratio was 18.6/1. Most of the cases (48.2%) were conflict related, whereas the rate of work, accidental, and sports related cases were (33.1%), (17.9%) and (0.01%), respectively. Final visual acuity (VA) ranged from no perception of light (23%) to 200/200 (17.1%). The number of cases with a final VA > 20/200 were 388 (49.3%). Initial visual acuity < 20/200, ocular trauma score category 1, zone 3 injury, additional vitrectomy surgery, and lens damage were found to be the main variables related with poor visual outcome in multivariate logistic regression analysis. CONCLUSION: Besides ocular trauma score category and initial VA; zone of injury, additional surgeries, and initial lens damage had negative effects on visual outcome in OGI.

Visual and ocular morbidity in severe open-globe injuries presenting to a regional eye centre in New Zealand.

IMPORTANCE: Open-globe injuries (OGI) are a leading cause of monocular blindness world-wide with considerable cost to the individual and society. BACKGROUND: To characterize the epidemiology, severity and outcomes of OGI treated at a major ophthalmology centre in New Zealand. DESIGN: Retrospective study. PARTICIPANTS: A total of 385 eyes of 381 patients over a 10-year period. METHODS: Eligible patients were identified using diagnosis and surgery codes on hospital discharge summaries. Clinical notes were reviewed to determine patient demographics, injury details, treatments and outcomes. MAIN OUTCOME MEASURES: Complications of injury, visual acuity at 3 months and final follow-up, and final status of the eye. RESULTS: The estimated annual incidence of OGI was 2.8 per 100 000. Working-age males predominated but age at injury ranged from 9 months to 90 years. Maori and Pacific peoples were over-represented. Injuries were severe with 58.7% presenting with vision of hand movements or worse. Penetrating injuries (56.4%) were most common, followed by globe ruptures (35.6%). Major complications included retinal detachment (15.8%), enucleation/evisceration (9.1%), phthisis bulbi (9.9%), endophthalmitis (2.6%) and sympathetic ophthalmia (0.26%). Despite the injury severity, 46% of eyes achieved final BCVA of ≥6/12. The Ocular Trauma Score (OTS) was a useful prognostic tool for stratifying severity of injury and predicting visual outcome (Fisher's exact test P < 0.001). CONCLUSIONS AND RELEVANCE: The incidence and severity of OGI in NZ are comparable to global statistics. Surgical repair can effectively recover vision, predicted well by the OTS. We identified at-risk groups to target with education and prevention strategies.

Visual outcomes and prognostic factors in open-globe injuries.

BACKGROUND: Ocular trauma is an important cause of visual loss worldwide. Improvements in our knowledge of the pathophysiology and management of ocular trauma during the past 30 years, in conjunction with advances in the instrumentation and techniques of ocular surgery, have improved the efficacy of vitreoretinal surgery in injured eyes. The aim of the current study was to determine the visual outcomes and prognostic factors of open-globe injuries in the Japanese population. METHODS: Retrospective study of 59 eyes of 59 patients presented with open globe injuries between September 2008 and March 2014 at Nagasaki University Hospital was conducted. Demographic factors including age, gender, and clinical data such as cause of injury, presenting visual acuity (VA), location of injury, type of injury, lens status, presence of intraocular foreign body, types of required surgeries, and final VA were recorded. According to the classification of Ocular Trauma Classification Group, wound location was classified into three zones. Chi-square test was used to compare presented data. RESULTS: Out of the 59 patients, 46 were placed in the Light Perception (LP) group, and 13 were placed in the No Light Perception (NLP) group. Work-related trauma was the most common cause (27 eyes) followed by falls (19eyes). Work-related trauma was common in males (P = 0.004), while falls was significantly common in females (P = 0.00001). Zone III injuries had statistically significantly poor prognostic factor compared to other zones (P = 0.04). All cases of NLP group (100%) presented with rupture globe. Poor VA at first visit (P = 0.00001), rupture globe (P = 0.026), history of penetrating keratoplasty (PK) (P = 0.017), retinal detachment (RD) (P = 0.0001), vitreous hemorrhage (VH) (P = 0.044), and dislocation of crystalline lens (P = 0.0003) were considered as poor prognostic factors. CONCLUSION: Poor VA at first visit, rupture globe, zone III injuries, history of penetrating keratoplasty, RD, VH, and dislocation of crystalline lens were found to be poor prognostic factors. PPV had a good prognostic value in open globe injuries associated with posterior segment involvement.

Visual and Refractive Outcomes of Children After Early Secondary Cataract Extraction Following Wound Repair for Penetrating Ocular Trauma.

PURPOSE: To evaluate the visual and refractive outcomes in children 8 years of age or younger with corneal laceration and cataract following penetrating ocular injuries who underwent primary corneal tear repair followed within 1 to 8 weeks by early secondary cataract extraction. METHODS: This retrospective, non-comparative case series reviewed the admission and operative charts of children 8 years of age or younger (range: 3 to 8 years) who underwent corneal wound repair as the primary surgical procedure followed within 1 to 8 weeks by cataract extraction with intraocular lens implantation, with a minimum follow-up period of 6 months. The main outcome measures were best corrected visual acuity (BCVA) and refractive error as the spherical equivalent at the final follow-up visit. RESULTS: A total of 47 children (33 boys, 14 girls) were included. The mean age at the time of injury was 5.9 ± 2.2 years (range: 3 to 8 years). Follow-up periods ranged from 6 months to 3 years (median: 18 months). The mean time gap between the wound repair and cataract extraction was 5 weeks (range: 1 to 8 weeks). Approximately 36 (77%) eyes obtained BCVA better than 6/18. All but one eye achieved BCVA better than 6/60. The deviation from emmetropia was less than 1.00 diopter (D) in 23 (54%) eyes, 1.00 to 3.00 D in 15 (35%) eyes, and more than 3.00 D in 5 (12%) eyes. CONCLUSIONS: Early removal of cataract with intraocular lens implantation 1 to 8 weeks after the primary wound repair in young children with penetrating corneal injuries can result in excellent visual and refractive outcomes with early intervention and aggressive amblyopia treatment.

Traumatic Ruptured Globe From a .22 Cartridge Casing in a 2-Year-Old Girl.

The authors report the case of a 2-year-old girl who presented with an acute ruptured globe secondary to penetration by the casing of a .22 caliber cartridge that was ignited by a car cigarette lighter. Although penetrating injuries are a common mechanism of ocular trauma, open globe induced by cartridge casing represents an unusual and preventable cause. [J Pediatr Ophthalmol Strabismus. 2017;54:e88-e90.].

An excellent anatomical and visual recovery after surgical repair of an open eye injury with poor baseline prognostic factors.

Presently described is case of a 42-year-old woman with eye injury that was result of gunshot fired by a man at a wedding celebration. Bullet penetrated inferior quadrant of nasal sclera of left eye 7-12 mm behind limbus. Choroid and vitreous were prolapsed around bullet. Hemorrhage, vitreous prolapse and lens subluxation were present in anterior chamber. Presenting visual acuity (VA) was hand motion. Bullet 14x5 mm in size was carefully extracted from the eye. Fifteen days later, argon laser photocoagulation was performed on retina in area of bullet entry point. VA was 20/25 (Snellen) at final visit. In this case, although foreign body was large, area of penetration was Zone III, and initial VA was poor, early and appropriate surgical repair achieved integrity of the globe and good vision prognosis.

The epidemiology of Open Globe Injuries presenting to a tertiary referral eye hospital in Australia.

BACKGROUND: Open globe injuries (OGIs) account for 44% of the cost of ocular trauma within Australia. It is estimated that 90% of ocular trauma is preventable. However, there have been few epidemiological studies within Australia that have identified groups at risk of OGIs specifically. The aim of our study was to review the epidemiology of OGIs presenting to a tertiary referral eye hospital in Australia. METHODS: The Birmingham Eye Trauma Terminology (BETT) system was used to classify injuries as globe ruptures, penetrating eye injuries (PEIs), intraocular foreign bodies (IOFBs) or perforating injuries. Demographic data, past ocular history, mechanism of trauma, ocular injuries, and best-corrected visual acuity (BCVA) before and after treatment were recorded. RESULTS: The 205 OGIs included 80 globe ruptures, 71 PEIs, 48 IOFBs and six perforating injuries. Falls predominated in older age groups compared to the other mechanisms of injury (p<0.0001). A fall was responsible for 33 globe ruptures and 82% of these had a history of previous intraocular surgery. Globe rupture and perforating injuries had poorer visual outcomes (p<0.05), consistent with previous studies. Alcohol was implicated in 20 cases of OGI, with 11 of these due to assault. PEIs and IOFBs commonly occurred while working with metal. BCVA was significantly worse following removal of an intraocular foreign body. We found presenting BCVA to be a good predictor of BCVA at the time of discharge. CONCLUSIONS: The causes of OGI varied in association with age, with older people mostly incurring their OGI through falls and younger adults through assault and working with metal. Globe ruptures occurring after a fall often had a history of intraocular surgery. The initial BCVA is useful for non-ophthalmologists who are unfamiliar with the ocular trauma score to help predict the BCVA following treatment.

Syrian Civil-War-Related Intraocular Foreign Body Injuries: A Four-Year Retrospective Analysis.

PURPOSE: To analyze the data of patients who underwent vitreoretinal surgery due to intraocular foreign body (IOFB) injuries that occurred in the Syrian civil war. METHODS: Seventy-eight eyes of 78 patients who underwent vitreoretinal surgery due to IOFB injuries that occurred during the Syrian civil war were analyzed. RESULTS: Forty-four eyes (56.4%) had traumatic cataract, 44 (56.4%) had retinal tears, 42 (53.8%) had vitreous hemorrhage, 18 (23%) had retinal detachment, 12 (15.3%) had endophthalmitis, and eight eyes had hyphema (10.2%). IOFBs consisted of metal in 62 eyes (79.4%), stone in eight eyes (10.2%), organic material in four eyes (5.1%), and glass in four eyes (5.1%). Approximately 86% of the eyes had initial VAs of 4/200 or worse. However, VAs improved in 64 eyes (82%) after the surgeries. CONCLUSIONS: Despite delays in treatment and the severity of injuries, 82% (64/78) of the eyes had an improvement in VA after the surgeries.
