Work-related open-globe injuries: demographics and clinical characteristics

Retinal Detachments after Open-Globe Injury: Risk Factors and Outcomes

PURPOSE

To identify risk factors for retinal detachment (RD) after open-globe injury (OGI) and evaluate outcomes of RD repair after OGI.

DESIGN

Case-control study.

PARTICIPANTS

Overall, 769 patients presented with 786 OGIs, which were surgically managed with ≥ 30 days of follow-up. Of the 786 eyes, 223 developed RD, the other 551 served as controls, and RD status of 12 eyes was unknown.

METHODS

A retrospective chart review was performed of all OGIs presented to the University of Michigan between 2000 and 2022. Multivariable regression identified risk factors for RD after OGI and predictors of poor vision after RD repair. Kaplan-Meier analysis estimated time from OGI to RD.

MAIN OUTCOME MEASURE

Predictors of visual outcome after RD repair after OGI.

RESULTS

After OGI, 223 (28.4%) of 786 eyes were diagnosed with RD, with > 73% diagnosed within a month. Predictors of RD include posterior injury (zone II vs. I odds ratio [OR], 1.60 [95% confidence interval {CI}, 1.04-2.46]; P = 0.0331; zone III vs. I OR, 2.29 [1.53-3.41]; P < 0.0001), vitreous hemorrhage (OR, 2.29 [1.54-3.1]; P < 0.0001), and presenting acuity worse than count fingers (CFs) (OR, 2.65 [1.69 - 4.16]; P < 0.0001). Retinal detachment repair took place in 142 of 223 eyes. The mean logarithm of minimal angle of resolution visual acuity (VA) improved from 2.3 ± 0.8 to 1.7 ± 0.9 after RD repair at 6-month follow-up, with 51.2% of eyes achieving CF or better vision. Single surgery anatomic success rate was 69.7% and final anatomic success was 88%. Predictors of vision worse than CF include history of ocular surgery (OR, 0.32 [0.11-0.94]; P = 0.039), proliferative vitreoretinopathy (PVR; OR, 0.39 [0.16 - 0.92]; P = 0.032), aphakia (OR, 0.25 [0.08 - 0.77]; P = 0.016), and redetachment (OR, 0.26 [0.1 - 0.63]; P = 0.003).

CONCLUSIONS

Most RD occur within the first month after OGI. Patients with posterior injuries, vitreous hemorrhage, or poor presenting VA were more likely to develop RD after OGI. Anatomic success was achieved in the majority, as was final VA of CF vision or better. History of ocular surgery, PVR at time of repair, aphakia, and redetachment were risk factors for a poor outcome.

Characteristics and Outcomes of Electric Bicycle-Related Open-Globe Injuries in a Tertiary Hospital in North China

BACKGROUND

The aim was to describe the characteristics and outcomes of patients treated for electric bicycle-related open-globe injuries (OGIs).

METHODS

A retrospective chart review of all patients who presented with electric bicycle-related OGIs was performed at the Hebei Eye Hospital in North China between January 2012 and December 2018. Demographic data, injury type, presenting clinical examination findings, best-corrected visual acuity (BCVA), secondary ocular complications, necessary surgical procedures and long-term outcome data were recorded.

RESULTS

Twenty-six patients with electric bicycle-related OGIs met the inclusion criteria and were enrolled in the study. Eighteen of the 26 patients (69.2%) were males. the average age of these patients was 44.0 years old. The injuries peaked in winter in the hour between 15:00 and 20:00. Among the patients, 23 (88.5%) were farm workers, 2 (7.7%) were industrial workers, 1 (3.8%) was student. The types of OGIs were 23 ruptures (88.5%), 3 penetrating injuries (11.5%). Data on zone of injuries included 1 zone I injuries (3.8%), 12 zone II injuries (46.2%), 13 zone III injuries (50.0%). Nine eyes (34.6%) had traumatic cataract, 24 eyes (92.3%) had vitreous hemorrhage, 20 eyes (79.9%) had retinal detachment, 19 eyes (73.1%) had choroidal detachment. Ten eyes (38.4%) had hand motion or worse vision at final follow-up. four eyes (15.4%) which had injuries involving all 3 zones resulted in enucleation or evisceration. With respect to BCVA, the initial BCVA was 2.7±0.3 and the final BCVA was 2.0±0.7, indicating that the patients' BCVA was significantly improved by surgery ( t =4.3, P <0.001).

CONCLUSIONS

Electric bicycle-related OGIs may have severe consequences. Modern surgical techniques can increase the rate of globe salvage although final vision remains poor. Therefore, increased awareness, proposed policies and suggestions should focus on regulating the use of electric bicycles and reinforcing laws and regulations to improve safety and prevent injuries.

Risk Factors for Enucleation Following Open Globe Injury: A 17-Year Experience

Purpose

At the time of open globe injury (OGI), it may be difficult for clinicians to predict which eyes are at highest risk for requiring enucleation. We performed a 17-year retrospective cohort study to report outcomes and risk factors for enucleation following open globe injuryto better aid clinicians counseling patients at OGI diagnosis.

Methods

A retrospective cohort study of all patients who presented to the University of Michigan with open globe injury (OGI) and were surgically managed between January 2000 and July 2017 was conducted. At least 30 days of follow-up was required. All eyes that ultimately underwent enucleation following OGI were identified and their clinical course analyzed. The main outcome measured was the rate of enucleation after OGI.

Results

There were 587 eyes meeting inclusion criteria. The mean patient age was 40.75 ± 25.1 (range 1–91). 441/585 (75.4%) patients were male. Average follow-up time was 1029.9 ± 1285.9 days. 116/587 eyes (19.8%) required enucleation after OGI, with 81.9% undergoing enucleation less than 30 days from injury. In enucleated eyes, the mean presenting logMAR vision was 2.91 ± 0.47 (Snellen equivalent between hand motion and light perception). The most common mechanism of injury requiring enucleation was globe rupture, 89/116 (76.7%), with 14/116 (12.1%) penetrating injuries and 13/116 (11.2%) perforating injuries. The mean age of patients that underwent enucleation was 45.6 ± 22.5 (range 3–91).

Conclusion

Open globe injuries are often visually devastating and a significant number of cases ultimately require enucleation. Despite emergent closure within 24 hours, 19.8% of eyes managed for OGI at our institution required eventual enucleation. 81.2% of these eyes required enucleation within 30 days of injury. Wound length greater than 10 mm, uveal prolapse, higher zone of injury, IOFB, and RAPD were identified as risk factors that predict future need for enucleation.

Demography, Clinical Settings and Outcomes in Evisceration with Implant: An Electronic Medical Records Driven Analytics of 2071 Cases

PURPOSE

To describe the demography, clinical settings and outcomes in 2071 patients undergoing evisceration across a multi-tier ophthalmology hospital network and comparison of results with the global scenario of clinical settings for evisceration.

METHODS

An analysis of 2071 patients undergoing evisceration and implant between 2013 and 2019.

RESULTS

The mean age at surgery was 39 ± 22 years. Children constituted 303(15%) of the cases. The four leading indications for surgery included painful blind eye in 760(37%), phthisis bulbi in 552(27%), staphyloma in 215(10%) and open globe injury in 195(9%) patients. The clinical settings encountered were trauma in 852(41%), ocular infection in 714(34%), glaucoma in 198(10%), post ocular surgery in 146(7%), congenital in 95(5%) and uveitis in 21(1%). Trauma and infection remained the commonest clinical settings in the urban (843,75%), rural (622,77%) and metropolitan (101,71%) areas. Decade wise distribution suggested trauma to be the commonest clinical setting in the first 4 decades and infection in the next 6 decades. The mean follow-up period was 351 ± 386 days (median 194). While trauma remained one of the commonest clinical setting in both the developed and the developing economies, painful blind eye and intractable glaucoma were other common clinical settings in the developed economies and infection was one of the leading clinical setting in the developing economies.

CONCLUSION

Most patients undergoing evisceration are young. The commonest indications for surgery include painful blind eye and phthisis bulbi. Trauma and infection remain the commonest clinical settings for evisceration in developed and developing economies.

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.

Clinical Characteristics, Visual Outcomes, and Prognostic Factors of Open Globe Injuries

Background and Objectives: Open globe injuries (OGI) remain an important cause of visual impairment and loss, impacting all ages. A better understanding of the factors influencing visual outcomes is important in an attempt to improve the results of the treatment of OGI patients. The author aimed to contribute to this knowledge with the analysis of clinical characteristics, prognostic factors, and visual outcomes of their cohort of OGI patients. Materials and Methods: A retrospective medical record review was performed for 160 patients (161 eyes) who sustained an open globe injury between January 2015 and December 2017 and presented to the Hospital of Lithuanian University of Health Sciences. Data analyzed included age, sex, type, cause, place of OGI, initial visual acuity (VA), final best-corrected visual acuity (BCVA), and tissue involvement. Open globe injuries were classified using the Birmingham Eye Trauma Terminology (BETT) and Ocular Trauma Classification System (OTCS). Univariate analysis was conducted to evaluate the prognostic factors. Results: The mean age of the patients was 41.9 years. The male-to-female ratio was found to be 8.4:1. The home was the leading place of eye injury (59.6%), followed by an outdoor environment (14.3%) and workplace (11.8%). Penetrating injury accounted for 43.5%, followed by intraocular foreign body injury (39.1%) and globe rupture (13%). Overall, 19.5% of patients regained a good final vision of ≥0.5, but for 48.1% of them, eye trauma resulted in severe visual impairment (BCVA ≤ 0.02). In the univariate analysis, a bad visual outcome of less than 0.02 was correlated with bad initial VA, iris dialysis, hypotony, vitreous hemorrhage, and vitreous prolapse at presentation. Phthisis bulbi was correlated with eyelid laceration, iris prolapse, iris dialysis, hyphema, vitreous prolapse, vitreous hemorrhage, and choroidal rupture at initial examination. Conclusions: Open globe injury remains an important preventable cause of ocular morbidity. This study provides data indicating that open globe injuries are a significant cause of visual impairment in our research group.

Eye trauma in the workplace: about 110 cases

AIM

To evaluate the epidemiological and clinical characteristics of occupational ocular trauma in order to determine prognostic factors of these eye accidents.

METHODS

This is a cross-sectional study of 110 patients who were victims of occupational accidents that caused eye trauma. They were treated in Department A, Hédi Rais Ophthalmology Institute in Tunis, between March 2018 and March 2019. We collected information from the patients' files according to a standard form. The data collected were: patient demographics, circumstances of the accident, consultation time, clinical examination data and temporary disability. The data were entered and statistically analysed using SPSS 20.0 software. We used the "t-student" and the "chi-deux" as statistical tests. The significance level was set at 5%.

RESULTS

We collected 120 eyes from 110 patients. The average age was 37 years with a male predominance. Almost half of the patients (45.4%) were construction workers.  In 34% of the cases, a metal object was responsible for the trauma. Projection of superficial foreign bodies was noted in 44.3% of cases and contusion in 34% of cases. The average visual acuity of the traumatised eye was 8/10 and depended on the nature of the trauma.  Palpebral ecchymosis (30.9%) and conjunctival hyperhaemia (48.5%) were the most common bio microscopic signs found. Eight cases of corneal wounds were noted, three cases of corneo-scleral wounds associated in 2 cases with an intra-ocular foreign body as well as three cases of bursting of the globe were noted. The risk factors of poor prognosis found were: male sex (p=0.042), the mechanism of the trauma: projection of a foreign body (p=0.0052) and the following occupations: bricklayer, mechanic and construction worker (p<0.0001). The average temporary disability caused by eye trauma was 5 days with a standard deviation of 6 days.

CONCLUSION

Our study described the severity of eye injuries related to work-related accidents. The most important prognostic factors will be the male gender, the mechanism of the trauma and the occupation. These traumas represent a major public health problem. Prevention is the only way to improve the final prognosis.

Open Globe Injuries Related to Traffic Accidents: A Retrospective Study

Purpose

To evaluate epidemiology, clinical characteristics and outcomes of patients sustained traffic-related open globe injury (OGI).

Methods

The medical records of all OGI patients who were admitted in a tertiary referral center from January 2006 to December 2016 were retrospectively evaluated. Then, the records of injuries related to traffic accidents were identified and reviewed in detail.

Results

Among the overall causes of OGI, traffic-related accidents comprised 92/978 (9%) of cases. Nearly half of the injuries (51%) occurred in the 20–39-year-old group and 59% involved automobile transportation. Globe rupture occurred in 48 (47%) eyes. Following treatments, LogMAR visual acuity (VA) significantly improved from a median (interquartile range) of 2.3 (1.9–2.3) to 1.7 (0.3–3.0), at the final appointment. Presence of relative afferent pupillary defect and presence of retinal detachment were predictors for poor final visual outcomes.

Conclusions

Traffic-related OGI had a high prevalence in the young. The risky transportation modes were motorcycles in teenagers and automobiles in young adults. Despite treatment, there was a considerable proportion of impaired final VA. This information could help establish effective safety education and encourage regular adherence to road safety behaviors in the high-risk groups.

Demographic trends of open globe injuries in a large inpatient sample

PURPOSE

To evaluate demographic trends of open globe injuries (OGIs) using a large dataset representative of United States population.

METHODS

Retrospective cross-sectional observational study using the National Inpatient Sample (NIS) database from 2002 to 2013. Only patients with a primary admitting diagnosis of OGI were included. Data included age (in years), gender, race, type of OGI, death rate and length and cost of stay.

RESULTS

During the 12-year period, 27,467 adults (age > 20) with acute OGIs were admitted to the US hospitals. The incidence of OGIs in the adult US population was 10.6 cases per 1,000,000 persons. The mean age was 50.4 years (SD 21.52); the average ages of men and women were 44.34 (SD 17.63) and 65.69 (SD 22.77), respectively. Men accounted for 71% of all cases, with 84% of patients under 60. A decrease in the number of OGIs was seen with advancing age in men, whereas the opposite was true for women. Men, elderly over 80 and Blacks were at the highest risk of sustaining an OGI. The most and least common types of injuries were penetrating injuries (73%) and IOFBs (11%), respectively. Over half of young adults in the 21-40 cohort and 43% of men were uninsured (p < 0.001). The average length of hospital stay increased with age and was significantly much higher in women than men (3.4 vs 2.5 days).

CONCLUSIONS

Racial, gender and age disparities are prevalent in patients with OGIs. Although the majority of cases were seen in Whites and young men age 21-40 years, the incidence of OGIs per 1,000,000 persons per year was the highest in Blacks and Hispanics, elderly over 80, and men. One-third of all cases were uninsured. These disparities should be the basis of future public health safety measures.

Open-globe-injury: A single center Spanish retrospective 5-year cohort study

PURPOSE

To review and analyze the epidemiological profile, clinical characteristics and visual outcomes in patients attended for traumatic open globe injury (OGI) at our hospital over a 5-year period.

DESIGN

Retrospective chart review study.

METHODS

Retrospective analysis of all patients attended at Fundación Jiménez Díaz University Hospital for OGI between 2011 and 2015. Data from 104 patients including demographics, ocular examination, medical and surgical treatment, visual outcomes, and complications were analyzed.

RESULTS

Most patients were male (79.8%) and the median age at the time of injury was 41 years (interquartile range 31.5-58 years). Work-related accidents represent more than half of the cases and their main mechanism was penetrating trauma or foreign body. This type of accident had good prognosis (median final visual acuity in decimal scale 0.8; interquartile range 0.4-1). Falls were the second most common cause of OGI, predominantly affecting senior women (50%), with a high incidence of ocular rupture (50%) and associating a poor visual prognosis (median final visual acuity 0.01; interquartile range 0-0.5). There was a strong correlation (0.75; p < 0.001) between ocular trauma score (OTS) and final best corrected visual acuity.

CONCLUSIONS

Two different patterns of OGI were identified in our sample. Work-related trauma in young males was the most common form of OGI and was associated with good prognosis. However, falls in senior women were associated with poor prognosis.

Trends in occupational-related open globe injury presenting to a tertiary referral centre of Northern Thailand

PURPOSE

To determine characteristics of occupational-related open globe injury (OGI) in a tertiary referral centre within an agricultural activity endemic area.

METHODS

The medical records of patients diagnosed as open globe injury received during work and admitted to Chiang Mai University Hospital, Thailand from January 2006 to December 2016, were retrospectively reviewed.

RESULTS

Six hundred and fifteen patients were included in this analysis with a mean (SD) age of 44.6 (14.1) years and a median (IQR) follow-up of 6.5 (2.5 to 17) months. Males were predominant (92%). The highest risk groups were patients in the age range of 40 to 59 years (52%). The common locations of injuries were gardening/farming (52%) followed by work at construction/industrial site (32%). Over the study period, there was an increasing proportion of intraocular foreign body (IOFB), while the proportion of penetrating injuries decreased (p = 0.001). An increasing frequency of injuries from mowing were noted (p = 0.003). Types of injury also varied in different working settings as follows: while higher proportion of penetrating OGI occurred at the office (86%), IOFB occurred more frequently at gardening/farming site (59%). Work setting did not influence either the initial visual acuity (VA) (p = 0.53) or the final VA (p = 0.73). Significant improvements in final VA were demonstrated across all work settings, but 46% of patients still had a final visual acuity worse than 20/400.

CONCLUSIONS

The majority of occupational-related OGI in this study were related to agricultural work. A high incidence of injuries during mowing and a high frequency of IOFB should be considered when discussing guidelines and public recognition should be raised regarding safety protective measures at work.

Validity of ocular trauma score in open globe injury patients from Turkey

OBJECTIVE

To determine the efficacy of ocular trauma score (OTS) in determining the prognosis in patients with open globe injury who admitted to our clinic.

MATERIALS AND METHODS

Data of patients with open globe injury who were admitted to our clinic between 2014 and 2016 were retrospectively analyzed. The OTS raw score of each patient was determined and translated into OTS categories according to OTS study. Prognostic results of OTS study and current study was compared with chi square analysis.

RESULTS

In our study, 101 eyes of 101 patients were examined. The mean age of the patients was 27.08±15.36 years. The mean follow-up period was 12.84±9.04 months. In total, 86 of the cases were male (85.1%). In our study, the mean initial visual acuity of the patients was 0.10±0.23. In 64.3% of the cases, IVA was at hand movement level or lower. IVA was found to be≥20/40 in 10.9%. The mean FVA was 0.38±0.37. In total, 41.6% of the cases had a FVA≥20/40. In 28.7% of these cases, FVA was at hand movement level or lower. While no significant difference was found in patients with OTS3, OTS 4 and OTS 5 (P>0.05), prognosis of patients with OTS 1 and OTS 2 was better than OTS study (P<0.001) CONCLUSION: Although OTS can be effective and safe data in terms of prognosis, it can be improved with more comprehensive studies.

Low-cut, low-vacuum vitrectomy for releasing an embedded intraocular foreign body

Background

Removal of an embedded intraocular foreign body remains challenging due to the risks of bleeding and retinal damage. We present a novel technique to deal with this situation.

Case report

A 32-year man presented with two months of decreased vision in one eye (best corrected visual acuity of 20/200), a year after a workplace injury that necessitated surgery for an open globe injury. Examination revealed the sequalae of his previous surgery, a subtotal retinal detachment and an embedded intraocular foreign body close to inferior ora serrata at the 6 'o clock position confirmed by imaging. The other eye was normal. A pars plana vitrectomy was performed and the embedded intraocular foreign body was released from surrounding dense adhesions using the vitrectomy probe set at 1000 cuts/minute and 100 mm Hg vacuum, followed by fluid air exchange and endolaser with silicon oil injection. The retinal detachment settled well post-operatively, and at the end of one month, the patient had best corrected visual acuity of 20/60.

Conclusions

The low-cut, low-vacuum vitrectomy technique can be considered as a safe option for releasing the embedded intraocular foreign body in complex ocular trauma scenarios.

Predictive factors of enucleation after open globe injuries

BACKGROUND

Trauma is the leading cause of enucleations in the USA. Current information regarding open globe injuries (OGI) is based mainly on data from individual tertiary care centers across the country which might skew the findings towards the population served by these level-one trauma centers. The aim of this study is to evaluate the demographics, characteristics, and risk factors of traumatic enucleations in a large data sample.

METHODS

Descriptive cross-sectional observational study using the National Inpatient Sample (NIS) Database from 2002 to 2013. Inpatients with traumatic enucleations were identified using ICD-9 codes. Chi-square and logistic regression analyses were used to identify differences between the enucleated and non-enucleated cohorts and to evaluate the predictive factors of enucleation in OGIs.

RESULTS

Enucleations were performed in 3020 (6.2%) of 48,563 OGIs identified. The average age in the enucleated cohort for males vs. females was 44.7 vs. 62.2 years. In the USA, the highest number of traumatic enucleations occurred in the 21-40 group (41.8%) and the fewest in the 80+ age group (11.8%). The risk of enucleation decreased across the age groups significantly. Compared with the 21-40 age group, the risk of undergoing enucleation was 15% lower in patients 41 to 60 years of age, 35% in patients 61 to 80, and 40% lower in patients over 80. In total, 5.1% OGIs in women and 6.7% of OGIs in men were enucleated. The risk of enucleation was 29% higher in men than in women. The highest absolute number of enucleations was seen in Whites. Compared with Whites, Blacks had a 63% higher risk of enucleation following an OGI. OGIs with rupture-type injury, endophthalmitis, or phthisis were significantly higher odds to be enucleated.

CONCLUSIONS

The risk of enucleation following traumatic OGI significantly increased for patients who were in the 21-40 age group, of Black race, or of male gender; the risk also increased if the injury was a rupture-type or associated with endophthalmitis or phthisis. The risk of depression was 75% higher in enucleated patients versus non-enucleated patients.

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.

Clinical characteristics and visual outcomes of work-related open globe injuries in Japanese patients

Purpose: To investigate the clinical characteristics and visual outcomes of patients with work-related open globe injuries (OGIs) and compare them with patients with non-work-related OGIs. Design: Retrospective, observational, multicentre, case-control study. Methods: A total of 374 patients with work-related OGIs and 170 patients with non-work-related OGIs who presented to hospitals that belong to the Japan-Clinical Research of Study group from 2005 to 2015 were included in this study. Clinical data including age, sex, initial and final visual acuity, type of open globe injury, lens status, zone of injury, wound length, and presence of proliferative vitreoretinopathy, retinal detachment, expulsive haemorrhage, and endophthalmitis were recorded. Main Outcome Measures: Visual acuity. Results Work-related OGIs were associated with younger age, male sex, better initial and final visual acuity, more laceration, smaller wounds, presence of retinal detachment, and expulsive haemorrhage, compared with non-work-related OGIs. Multiple regression analysis revealed that final visual acuity is significantly associated with initial visual acuity, wound length, and the presence of proliferative vitreoretinopathy in work-related OGIs. Conclusions: Work-related OGIs showed better visual outcomes than other OGIs. Initial visual acuity, wound length, and the presence of proliferative vitreoretinopathy are predictors of visual outcomes in patients with work-related OGIs.

Visual Outcomes and Prognostic Factors of Intralenticular Foreign Bodies in a Tertiary Hospital in North China

Purpose

The aim of this study is to describe the epidemiological and visual outcomes and to identify the main prognostic factors of intralenticular foreign body (ILFB) injuries.

Methods

We performed a retrospective review of 21 patients (21 eyes) referred to Hebei Eye Hospital in North China from January 2012 to December 2017, who underwent surgical removal of ILFBs and associated ocular trauma repairs. Data regarding the patient demographics, cause of the injury, nature of the ILFB, clinical features, time interval between the injury and the ILFB removal, time interval between the presentation and the surgery, and the initial and final best-corrected visual acuities (BCVAs) were analyzed, and the main prognostic factors were identified.

Results

Male adults were most affected by ILFBs (90.5%). The mean age of the patients was 41.5 years (median: 46 years, range: 21 to 60 years). None of the patients were wearing goggles at the time of the injury. The most common ILFB cause was hammering the metal (57.1%), and most of the ILFBs were metallic (71.4%). After medical treatment, the final BCVA was improved significantly (Z = 2.49, P=0.015). There was a significant association between the ILFBs with posterior segment injuries and the final BCVA (χ² = 10.03, P=0.01). Those factors showing no statistical association with the final BCVA included the age (χ² = 0.36, P=1.0), gender (χ² = 0.52, P=1.0), nature of the ILFB (χ² = 1.11, P=0.54), entrance wound location (χ² = 2.85, P=0.25), and time interval between the injury and the ILFB removal (χ² = 1.87, P=0.23).

Conclusion

This is the first local study to explore the epidemiology of ILFB injuries and to identify the main prognostic factors. There was a significant association between the ILFBs with posterior segment injuries and the final BCVA. Improved public awareness and strengthened education regarding safety are the key approaches to reduce the incidence of eye injuries.

Combined branch retinal artery and branch retinal vein occlusion from a globe penetrating nail gun injury

Background: Nail gun injuries represent a significant proportion of work-related ocular trauma. Here we report a rare case of a combined branch retinal arterial occlusion (BRAO) and branch retinal venous occlusion (BRVO) from a nail gun injury in a patient who was wearing eye protection.

Case description: A 23-year-old male presented with a left globe penetrating injury from a pneumatic nail gun. The nail ricochet bypassed the patient’s protective eyewear, penetrating the left globe causing multiple retinal tears and a combined BRAO and BRVO in the inferior temporal vascular arcade. The patient underwent prompt surgical repair obtaining an excellent anatomic outcome. However, the visual outcome was 20/200 OS at one and two years post injury primarily due to extensive ischemic damage of the retina.

Conclusion: This case is the first to describe a combined BRAO and BRVO from a globe penetrating injury. What makes this case even rarer is that the patient was wearing eye protection at the time of the injury. Despite appropriate emergency management, rapid referral for ophthalmologist assessment, and timely surgical management of this patient, the visual outcome was poor. The vascular injury ultimately compromised a significant segment of the retina, including the macula.

Ocular Siderosis Secondary to Retained Intraocular Foreign Body: A Case Report

Intraocular foreign bodies (IOFBs) can present in an insidious manner. A 20-year-old male presented with gradual visual loss in the right eye over a six-month period. He was found to have a dense cataract. During examination he was noted to have a small, healed corneal scar and subtle iris heterochromia. Further questioning revealed a previously undisclosed metal-on-metal hammering injury concerning for an IOFB. B-scan ultrasonography was inconclusive and CT studies confirmed the presence of IOFB. The patient underwent a combined cataract extraction with intraocular lens implantation with a pars plan vitrectomy, removal of IOFB, and endolaser. He had an excellent visual outcome, despite developing siderosis. A high index of suspicion should be raised for any asymmetric cataract formation, especially in younger patients. Careful examination for findings such as healed corneal scars or iris heterochromia may aid in diagnosing previously undisclosed injuries.

Epidemiological Characteristics of Work-Related Ocular Trauma among the Carpenters in Medan, Indonesia

BACKGROUND

Medan is the capital of North Sumatera Province and the most industrialised area of North Sumatera. One of the largest industries in Medan is the wooden industry. Ocular trauma is often happened in Medan and causes a serious problem.

AIM

This study aimed to analyse the correlation between ocular trauma among the carpenters and the using of eye protection during work and educational level.

METHODS

This study is conducted among the carpenters that work in the wooden industry. There were 30 carpenters that being observed about age, educational level and working hours and the using of eye protection during work that might be related to ocular trauma. All carpenters completed a comprehensive examination and interview.

RESULTS

The most common age range of ocular trauma was between 26-45 years (56.7%), and all were male. Most of the traumatised carpenters educational level had a higher educational level (50%), and workers that had traumatised works more than 8 hours a day (66.7%). From this study, there was a significant correlation between ocular trauma among the carpenters and age (p = 0.047), and working hours (p = 0.039).

CONCLUSION

No significant correlation between ocular trauma among the carpenters and the using of eye protection during work (p = 0.464), and educational level (0.925) was found. Furthermore to anticipate the high rate of worked-related ocular trauma required labour regulations that cover the age of recruitment workers and working hours a day. Work safety regulation protects the workers from work-related ocular trauma.

Clinical characteristics and outcomes of open globe injuries in Japan

PURPOSE

To describe the epidemiology and clinical outcomes of open globe injuries (OGIs) in Japan over 10 years, and examine preoperative factors influencing the visual prognosis after surgery.

STUDY DESIGN

Retrospective, observational, multicenter case-series study.

METHODS

Patients' data were entered into a computerized database for review and statistical analyses. The following parameters were assessed; age, gender, initial and final visual acuity, duration between onset and surgery, presence of lens in the eye, characteristics of injury, presence of ocular complications, and number of surgeries.

RESULTS

The records of 374 eyes with OGI were enrolled. The average age of the patients was 56.8 ± 22.1 years, and the majority of patients were men (73.5%). Compared to the overall cohort, work-related OGI was the most common, associated with significantly better final visual acuity, whereas patients with fall-down OGI showed significantly worse final visual acuity (P < 0.05). Among the types of injury, both the initial and final visual acuity were significantly worse in the rupture group than in the laceration group. Multiple liner regression analyses revealed that the final visual acuity was significantly associated with initial visual acuity, type of injury (rupture), retinal detachment, and proliferative vitreoretinopathy.

CONCLUSION

To predict the visual outcome in patients with OGI, ophthalmologists need to pay attention not only to the initial visual acuity but also to initial ocular conditions, such as the presence of ocular complications.

Clinical characteristics and outcomes of fall-related open globe injuries in Japan

PURPOSE

To investigate the clinical characteristics and visual outcomes in patients with fall-related open globe injuries and to evaluate differences between fall-related and non-fall-related open globe injuries in Japan.

METHODS

A retrospective review of patients with open globe injury who presented to Japan-Clinical Research of Study (J-CREST) hospitals between 2005 and 2015 was enrolled. Clinical information including age, sex, initial visual acuity, final visual acuity, type of injury, status of the crystalline lens, zone of injury, wound length, presence of retinal detachment, proliferative vitreoretinopathy, expulsive hemorrhage, and endophthalmitis was recorded.

RESULTS

A total of 374 eyes were enrolled, of which 120 (32.1%) suffered from fall-related injury with average age of 73.7 ± 15.9 years (range, 11-101 years). A majority of patients were female (55.8%). Of 120 patients with fall-related injury, 109 (90.8%) presented with rupture and 11 (9.2%) with laceration. A multiple regression analysis revealed that final visual acuity was significantly associated with initial visual acuity (r = 0.99, P < 0.001). Compared to non-fall-related open globe injuries, fall-related open globe injuries were associated with elderly age, female sex, poorer initial and final visual acuity, rupture, absence of the lens, larger wound size, retinal detachment, expulsive hemorrhage, and absence of endophthalmitis (P < 0.01).

CONCLUSIONS

Fall-related open globe injuries were more frequent in elderly female and accompanied by larger wound lengths and severer ocular complications. Visual outcomes in patients with fall-related open globe injuries were related to initial visual acuity.

POSTTRAUMATIC ENDOPHTHALMITIS: An 18-Year Case Series

PURPOSE

To describe the demographics, characteristics, management, and visual outcomes of eyes diagnosed with endophthalmitis after open globe injury.

METHODS

Retrospective cohort analysis of all patients diagnosed with endophthalmitis after open globe injury from 1997 to 2015 at University Hospital, Newark, NJ.

RESULTS

Twenty-six eyes were identified (all male patients; mean age: 37 ± 15 years). Cultures were positive in 16 eyes (62%), with Staphylococcus species (7 eyes, 44%) being the most common organism. Twelve eyes (46%) presented with open globe injury and concurrent endophthalmitis; 14 eyes (54%) developed endophthalmitis a mean of 14 days after open globe repair (OGR; 1 outlier of 98 days excluded). All eyes were managed with systemic and intravitreal antibiotics. The presence of intraocular foreign body (P < 0.05) and delayed primary OGR (P < 0.03) were significantly more common with concurrent versus post-OGR endophthalmitis. Four (29%) eyes in the post-OGR endophthalmitis group had corneal wound leak after OGR. Four (15%) eyes with no light perception vision were enucleated. Ten (40%) of 25 eyes with documented best-corrected visual acuity had final best-corrected visual acuity ≥20/200; final best-corrected visual acuity ranged from no light perception to 20/20.

CONCLUSION

The presence of intraocular foreign body and delayed presentation were significantly more common with concurrent endophthalmitis. Twenty-nine percent of eyes that presented with endophthalmitis after OGR had a wound leak. Final best-corrected visual acuity ≥20/200 was achieved in 40% of cases.

Epidemiologic characteristics and outcomes of open globe injury in Shanghai

AIM

To investigate the epidemiologic characteristics and outcomes of open globe injury in Shanghai.

METHODS

A retrospective study was conducted for 148 unilateral open globe injury cases presenting to a tertiary referral hospital of Shanghai. Electronic medical records were reviewed and phone surveys were conducted to collect and analyze 1) background of patient; 2) setting of injury and clinical signs at presentation; 3) treatment procedure and outcome; 4) quality of life after injury.

RESULTS

There were more male patients (77.03%) than females (22.97%), more temporary habitants (79.05%) than residents (20.95%). The subjects in this study presented a significantly lower constitutional status of education than that of the whole Shanghai population (P<0.001). Occupational injury was the first cause of injuries (39.86%), followed by home accident (20.27%), road accident (16.89%), violent behavior (16.89%) and outdoor injury (6.08%). The 143 subjects (96.62%) were not wearing spectacles at the time of injury. Of all patients, 77 subjects (52.03%) had the outcome of no vision (including enucleation). The classification and regression tree (CART) prognosis presents 59.58% sensitivity to predict visual survival correctly and 80.19% specificity to predict no vision correctly. The patients whose injured eye had no vision reported more reduction of life quality.

CONCLUSION

We found that male subject, temporary habitants, low educational status and no eyewear are risk factors of open globe injury in Shanghai. Occupational injury is the leading cause. CART analysis presents a certain agreement to the actual visual outcome. The injury imposes negative impact on quality of life especially in no vision cases. The education of eye protection may help to avoid the injury.

Indications for enucleation and evisceration in a tertiary eye hospital in Riyadh over a 10-year period

BACKGROUND

Enucleation and evisceration are eye removal procedures considered as palliative treatment when all other therapeutic options are exhausted.

OBJECTIVE

Describe the causes and histopathological findings leading to enucleation/evisceration, and correlate the clinical findings with the histopathological findings.

DESIGN

Retrospective, descriptive study.

SETTINGS

Tertiary care hospital, Riyadh, Saudi Arabia.

PATIENTS AND METHODS

The medical records of patients who underwent enucleation or evisceration from February 2005 to May 2015 were reviewed. Patients were classified into two categories based on indications of surgery: traumatic and nontraumatic. Causes of ocular injury in the traumatic group were documented, and the histopathological findings were reviewed for the nontraumatic cases.

MAIN OUTCOME MEASURE(S)

Number of enucleation and evisceration surgeries and their causes and histopathological findings.

RESULTS

One hundred ten patients underwent evisceration (n=69, 63%) and enucleation (n=41, 37%). Causes were traumatic in 38 (35%) and nontraumatic in 72 (65%). The median age was 50 years and there were 64 men and 46 women. Postoperative endophthalmitis was the most common indication for surgery (n=24, 21.8%), followed by painful blind eye (n=22, 20%). Ocular trauma was more predominant in men (n=29, 76%) than in women (n=9, 24%), and the leading mechanism of trauma was metallic nail injuries (n=6, 15.8%). In the nontraumatic group, endophthalmitis was the most common histopathological finding (n=25, 34.7%).

CONCLUSIONS

The majority of the eye enucleation/evisceration surgeries were due to nontraumatic causes, especially postoperative infections. However, severe eye trauma was still a main indication for this destructive procedure. Guidelines are needed to decrease the incidence/severity of work-related eye injuries and to detect and manage eye infections earlier and more promptly.

LIMITATIONS

Retrospective study, in one hospital in one area; therefore, results cannot be generalized.

Work-Related Eye Injuries: A Relevant Health Problem. Main Epidemiological Data from a Highly-Industrialized Area of Northern Italy

The province of Modena is one of the most industrialized areas of Northern Italy. The medical records of the Ophthalmological Emergency Department (OED) of Modena University Hospital were studied: there were 13,470 OED accesses in 2014 and in 754 cases that an occupational eye injury occurred. The frequency of work-related eye injuries (3‰) was lower compared to other published studies, but the absolute number is still relevant, showing the need for more adequate prevention, especially in metal work, construction work, and agriculture, where the worst prognoses were observed. Intervention programs must be implemented as early as possible in the working life, considering that the frequency in younger workers is about double that of the oldest age class (3.5‰ vs. 1.8‰), and special attention should also be given to foreigners, who have a 50% higher injury risk. Furthermore, the planning of specific interventions for eye-injured workers may be useful, considering that a previous injury does not appear to encourage the adoption of preventive interventions, and a subgroup of eye-injured workers have a potential risk for new injuries. Finally, the data presented here indicates how OED records, integrated with specific occupational information, can be applied for studies on work-related eye injuries.

Validation of the Retinal Detachment after Open Globe Injury (RD-OGI) Score as an Effective Tool for Predicting Retinal Detachment

PURPOSE

The Retinal Detachment after Open Globe Injury (RD-OGI) Score is a clinical prediction model that was developed at the Massachusetts Eye and Ear Infirmary to predict the risk of retinal detachment (RD) after open globe injury (OGI). This study sought to validate the RD-OGI Score in an independent cohort of patients.

DESIGN

Retrospective cohort study.

PARTICIPANTS

The predictive value of the RD-OGI Score was evaluated by comparing the original RD-OGI Scores of 893 eyes with OGI that presented between 1999 and 2011 (the derivation cohort) with 184 eyes with OGI that presented from January 1, 2012, to January 31, 2014 (the validation cohort).

METHODS

Three risk classes (low, moderate, and high) were created and logistic regression was undertaken to evaluate the optimal predictive value of the RD-OGI Score. A Kaplan-Meier survival analysis evaluated survival experience between the risk classes.

MAIN OUTCOME MEASURES

Time to RD.

RESULTS

At 1 year after OGI, 255 eyes (29%) in the derivation cohort and 66 eyes (36%) in the validation cohort were diagnosed with an RD. At 1 year, the low risk class (RD-OGI Scores 0-2) had a 3% detachment rate in the derivation cohort and a 0% detachment rate in the validation cohort, the moderate risk class (RD-OGI Scores 2.5-4.5) had a 29% detachment rate in the derivation cohort and a 35% detachment rate in the validation cohort, and the high risk class (RD-OGI scores 5-7.5) had a 73% detachment rate in the derivation cohort and an 86% detachment rate in the validation cohort. Regression modeling revealed the RD-OGI to be highly discriminative, especially 30 days after injury, with an area under the receiver operating characteristic curve of 0.939 in the validation cohort. Survival experience was significantly different depending upon the risk class (P < 0.0001, log-rank chi-square).

CONCLUSIONS

The RD-OGI Score can reliably predict the future risk of developing an RD based on clinical variables that are present at the time of the initial evaluation after OGI.

Demographic Characteristics and Clinical Outcome of Work-related Open Globe Injuries in the Most Industrialised Region of Turkey

Objectives:

To evaluate demographic characteristics and clinical outcomes of work-related open globe injuries in the most industrialized region of Turkey.

Materials and Methods:

The demographic and medical records of patients with work-related open globe injuries who presented to the ophthalmology or emergency departments with an official occupational accident report were retrospectively reviewed. Visual acuity categories were defined according to the World Health Organization. The injury types and zones of the open globes were classified according to Birmingham Eye Trauma Terminology System.

Results:

Among 479 patients with work-related eye injuries in 5 years, there were 102 eyes of 101 patients with open globe injuries (21%). The mean age of the patients was 34.5±8.9 years with a mean follow-up of 12.5±12.6 months. The injuries peaked in June in the hour between 12:00 and 13:00. Eighty-six percent presented to emergency services within 12 hours after the injury. Twenty-two percent of the patients had been wearing protective eyewear at the time of injury. The open globe injuries were penetrating in 51%, intraocular foreign body in 40%, rupture in 7% and perforation in 2% of the eyes. The most frequent finding was traumatic cataract. Final visual acuity of 33.3% of patients was below 3/60. Seventy-eight percent of patients that had visual acuity worse than 6/18 at presentation had visual acuity of 6/18 or better at final visit. Sixty-three percent of eyes which had injuries involving all 3 zones resulted in phthisis bulbi, enucleation or evisceration.

Conclusion:

Work-related open globe injuries may have severe consequences such as visual impairment and blindness among the young male working population in industrialized areas. Nearly half of the occupational open globe injuries resulted in visual impairment and blindness.

Development of medical treatment for eye injuries in the mainland of China over the past decade

In the article, the development of medical treatment for eye injuries in the mainland of China was reviewed. According to the data provided in Eye Injury Vitrectomy Study (EIVS), 27% of 72 eyes with no light perception (NLP) gained recovery in term of antomy and visual function. Vitrectomy initiated at more than 4 weeks after open eye injury is an independent risk factor for developing PVR. Prognosis of anatomy and visual function of the injured eye with PVR is markedly worse than that without PVR. Serious injuries of ciliary body, choroid and retina are three key parts of the eye with NLP. The concept that the treatment of the eye injury gradually focus on the whole globe is embodied. The data from 13575 in patients with traumatic eyes in 14 hospitals revealed that the rate of immediate enucleation was remarkable reduced with comparison of 20 years ago.

Visual outcome after emergency surgery for open globe eye injury in Japan

Background

Most patients with open globe eye injury are brought to hospital as emergency patients and usually require admission for emergency surgery. We analyzed the visual outcome in patients with open globe eye injury at our hospital over a 4-year period.

Patients and methods

This study reviewed 40 eyes of 40 patients with open globe eye injury who were presented to Juntendo University Shizuoka Hospital and required emergency surgery during the 4 years from January 2010 to December 2014. Retrospective evaluation of the visual outcome was performed using data from the medical records, including assessment of the influence of sex, side of the eye injury, cause of injury, and site/severity of injury.

Results

The mean age (SD) at the time of the injury was 58.9 years (±25.1 years). There were 28 males (70.0%) and 12 females (30.0%). Statistically significant improvement in visual acuity after treatment was noted in the males (P=0.0015, Wilcoxon test), but not in the females. Twenty-five patients had injury to the right eye (62.5%) and 15 had injury to the left eye (37.5%). A significant improvement in visual acuity was achieved after treatment of injury to the right eye (P=0.021), but not the left eye (P=0.109). The most frequent cause of injury was an accident (15 eyes; 37.5%). The second most frequent cause was work-related injury (14 eyes; 35.0%), which only occurred in males, and the third cause was accident due to negligence (eleven eyes; 27.5%). Two patients developed sympathetic ophthalmia and one patient developed postoperative endophthalmitis.

Conclusion

The majority of patients with open globe eye injury were male workers in Japan. The visual outcome of work-related injury was better than that of injury due to other causes. The visual outcome was also better if the right eye was injured compared with the left eye. Patients with injuries due to negligence were older than the other groups, and this finding might be characteristic of an aging society.

Epidemiological Characteristics of Work-Related Ocular Trauma in Southwest Region of China

Purpose: To determine the epidemiological characteristics of work-related eye injury in representative southwest region of China. Methods: Patients with eye injuries treated at the Ninth People’s Hospital of Chongqing from 1 January 2014 to 31 December 2014 were included in the current study. All patients completed a comprehensive examination and interview. Demographic characteristics and injury details were recorded. The International Classification of Diseases (ICD-10) and Birmingham Eye Trauma Terminology (BETT) were used. Results: The average age of eye injury patients was 37.52 years and the majority were male. Among the 1055 total patients, approximately 42.9% of the injuries were work-related. The highest proportion of occupational eye trauma was observed in the group between 36 and 45 years of age. Occupational ocular trauma occurred more frequently in summer, with most from 16:00 to 18:00. Metal was the most common injury cause. Foreign body on external eye was the most common diagnosis. Workers in the manufacturing industry without pre-work safety training or eye protection were far more likely to suffer from occupational ocular trauma than those with training and protection. Conclusions: This study provides insight into the epidemiological characteristics of occupational ocular trauma in southwest region of China. The current findings might be considered as a baseline for future research on regional work-related eye injuries. Our findings will provide valuable information for further development of preventive strategies.

Work-Related Eye Injuries: Important Occupational Health Problem in Northern Thailand

PURPOSE

This study was aimed to determine demographics, clinical characteristics, and factors associated with work-related eye injury in Northern Thailand.

DESIGN

A prospective case series.

METHODS

Eye injuries from any cause treated at a university-based hospital in Northern Thailand from March 2007 to June 2008 were included. In addition to comprehensive eye examination and standard treatments, patients' occupation, type of activity at the time of injury, alcohol consumption, and eye protection were studied. Eye injuries were classified based on the Birmingham Eye Trauma Terminology System. Demographic and clinical data were documented using a form adapted from the United States Eye Injury Registry.

RESULTS

Of the 101 eyes (97 patients) with work-related injury, 94% were men with a mean age of 39.5 ± 12.9 years (range, 19-72 years). Ninety-eight percent (95/97 patients) did not use protective eyewear. Open-globe injuries were found in 58/101 (57%) eyes. Agricultural workers experienced a higher number of open-globe injuries (37/58 eyes, 64%), whereas construction workers experienced a higher number of closed-globe injuries (25/43 eyes, 58%). In multivariable logistic regression models, nailing (odds ratio, 97.2; 95% confidence interval, 2.6-363.4; P = 0.01) and motorized grass trimming (odds ratio, 14.3; 95% confidence interval, 1.0-206.2; P = 0.05) were significantly associated with open-globe injuries when compared with closed-globe injuries. Significantly greater numbers of eyes with open-globe injuries had final vision equivalent to legal blindness (visual acuity, <3/60) compared with closed-globe injuries (42% vs 12%, P = 0.001).

CONCLUSIONS

Work-related open-globe injuries are relatively more common among agricultural workers in Northern Thailand. Protective eyewear should be aggressively promoted among workers engaged in nailing and motorized grass trimming.

Open-globe injuries with motor vehicle accidents: a 12-year review

PURPOSE

To evaluate demographics, characteristics, and outcomes of open-globe injuries (OGIs) in motor vehicle accidents (MVAs).

METHODS

Retrospective chart review of patients with OGIs related to MVAs that presented to University Hospital, Newark, from 2000 to 2012.

RESULTS

Twenty-five patients were identified; the average age of the patients was 33.3 years old (range, 5-75). The majority of patients (64 %) were males. The 25 vehicles comprised 24 automobiles and one motorcycle. Ten patients (40 %) wore seatbelts, and five (20 %) did not wear seatbelts. The seatbelt status was not documented in the remaining cases. Ethanol was documented as a contributing factor in five of the accidents. In terms of open-globe classification, 15 OGIs (60 %) were ruptures, and five (20 %) were penetrating injuries; three (12 %) had intraocular foreign bodies. Ten eyes (40 %) had a final VA of 20/400 or worse. Fourteen eyes (56 %) achieved a final VA of 20/200 or better; seven eyes (28 %) achieved a final VA of 20/40 or better.

CONCLUSION

Fifty-six percent of eyes with an open-globe injury related to MVAs achieved a final VA of 20/200 or better in this series. No eyes developed endophthalmitis.

Retinal detachment after open globe injury

PURPOSE

To characterize the development of retinal detachment (RD) after open globe trauma.

DESIGN

Case-control study.

PARTICIPANTS

A total of 892 patients comprising 893 open globe injuries (OGIs), of whom 255 were ultimately diagnosed with RD, with the remaining eyes serving as controls.

METHODS

Retrospective chart review of patients with OGIs presenting to the Massachusetts Eye and Ear Infirmary between 1999 and 2011. Kaplan-Meier analysis was used to estimate the time to detachment, and multivariable logistic regression was used to define the clinical factors associated with RD after OGI.

MAIN OUTCOME MEASURES

Demographic and clinical characteristics at the time of presentation after OGI, date of RD diagnosis, and last date of follow-up.

RESULTS

Primary repair of the open globe was typically undertaken within hours of presentation. A total of 255 eyes were ultimately diagnosed with RD after open globe trauma, yielding an incidence of 29% (95% confidence interval, 26-32). For eyes that developed RD, 27% (69/255) detached within 24 hours of primary open globe repair, 47% (119/255) detached within 1 week, and 72% (183/255) detached within 1 month. Multivariable regression analysis revealed the presence of vitreous hemorrhage (odds ratio [OR], 7.29; P < 0.001), higher zone of injury (OR, 2.51 per integer increase in zone number; OR, 1.00-6.30; P < 0.001), and poorer logarithm of the minimum angle of resolution (logMAR) visual acuity at the time of presentation after OGI (OR, 2.41 per integer increase in logMAR visual acuity; OR, 1.00-81.30; P < 0.001) to be associated with RD. A screening tool was created: the Retinal Detachment after Open Globe Injury score.

CONCLUSIONS

Retinal detachment is common after open globe trauma, although often not appearing until days to weeks after the initial traumatic event. Several clinical variables at the time of initial presentation can predict the future risk of detachment.
