Causes, occupational risk and socio-economic determinants of eye injuries: a literature review

Association Between Socioeconomic Deprivation and Orbital Trauma in a Hospital-Based Population

PURPOSE

To examine the association between area-level socioeconomic deprivation and orbital trauma among emergency ophthalmology consults.

METHODS

We conducted a cross-sectional study using 5-year Epic data for all hospital-based ophthalmology consults at the University of Maryland Medical System, and the Distressed Communities Index (DCI) data for area-level socioeconomic deprivation. We ran multivariable logistic regression models adjusting for age to compute odds ratios (OR) and 95% confidence intervals (CI) for the association between the DCI quintile 5 distressed score and orbital trauma.

RESULTS

A total of 3,811 cases of acute emergency consults were identified, of whom 750 (19.7%) had orbital trauma and 2,386 (62.6%) had other traumatic ocular emergencies. The odds of orbital trauma among people living in a distressed community were 0.59 (95% CI 0.46-0.76) times the odds for those living in a prosperous community. Among White subjects, the odds of orbital trauma for people living in a distressed community were 1.71 (95% CI 1.12-2.62) times the odds for those living in a prosperous community; among Black subjects, the OR was 0.47 (95% CI 0.30-0.75; p-interaction = 0.0001). Among women, the OR for orbital trauma among those living in a distressed community was 0.46 (95% CI 0.29-0.71); among men, the OR was 0.70 (95% CI 0.52-0.97; p-interaction = 0.03).

CONCLUSION

Overall, we found an inverse association between higher area-level socioeconomic deprivation and orbital trauma among both men and women. The association varied by race, such that there was an inverse association with higher deprivation among Black subjects in contrast to a positive association among White subjects.

Epidemiological and clinical characteristics of open globe injuries in Southwest China

Background

Open globe injuries (OGIs) are one of the leading causes of monocular vision loss, and the clinical characteristics of OGIs are region specific. The features and patterns of OGIs in Southwest China are poorly known and not well studied. Our study aimed to review the epidemiological and clinical characteristics of patients hospitalized for OGIs in Southwest China.

Methods

A retrospective study of OGI patients admitted to the West China Hospital from January 1st, 2015, to December 31st, 2019, was performed. Demographic characteristics and injury details were recorded. The Birmingham Eye Trauma Terminology system and the ocular trauma score (OTS) were used.

Results

A total of 3,014 patients were included. The male-to-female ratio was 5.2:1, and the mean age was 35.6 ± 19.1 years. 15.2% of patients were from the ethnic groups. The highest-risk occupation was the farmer (30.3%), followed by the worker (28.5%). OGIs occurred more frequently in people with middle (37.0%) and primary school (33.1%) education levels. Types of injuries included 46.8% penetration, 21.2% rupture, 2.9% perforation, and 29.1% intraocular foreign body (IOFB). The injuries types differed between age and occupation groups (p < 0.001). IOFBs had a higher risk of causing endophthalmitis, retinal detachment, and traumatic cataracts (p < 0.001). The most common injuries resulted from sharp objects (72.7%). The causes of the injuries were significantly associated with age, ethnicity, and occupation (p < 0.001). Explosion injuries and attacks by animals were more common among people of Tibetan and Yi ethnicities. Blunt trauma, vehicle crashes, falls and age older than 60 years were risk factors for a lack of light perception and lower OTS scores prognosis.

Conclusion

OGIs in Southwest China mainly affected working-aged males, especially workers or farmers. Severe vision loss and IOFBs are more common findings. OGIs in older patients and ethnic minorities requires additional attention.

Insights Into Ocular Resilience: Unraveling the Epidemiology, Prognostic Factors, and Visual Triumphs of Open Globe Injuries in the COVID-19 Era at a Leading Tertiary Care Centre of Western Rajasthan, India

INTRODUCTION

This study was conducted to describe the epidemiology, prognostic factors, and visual outcomes of open globe injuries (OGIs) at a tertiary care centre in Western Rajasthan, India.

METHODS

Data of OGI patients treated at the Department of Ophthalmology, All India Institute of Medical Sciences, Jodhpur, Rajasthan, from March 2019 to December 2021 were reviewed retrospectively. Demographic details including age, gender, place of injury, wound characteristics (i.e., cause, mechanism, location, and size), visual acuity (VA), and associated ocular injuries were recorded. The Ocular Trauma Classification System (OTCS) and the Birmingham Eye Trauma Terminology (BETT) were used to categorize OGIs. All the data was entered into a Microsoft Excel sheet (Microsoft Corporation, Redmond, Washington, United States) and analyzed with IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States).

RESULTS

A total of 40 patients with OGIs were included. OGI was discovered to be four times higher in males and 47.5% of the total cases were observed in patients aged 0-15 years, followed by patients aged 16-30 (27.5%). The rupture injury showed a higher incidence rate (32.5%) than the penetrating injury (62.5%). Of all OGIs, 75% were grade 4 injuries, with zone 1 being the most often affected zone and wood stick injury being the most prevalent aetiology. A significant difference was noted (p<0.001) in comparing presenting VA with final VA with paired sample t-test. A negative Spearman correlation was noted between age and final VA (r = 0.53, p = 0.000), and the grade of injury and final VA (r = 0.51, p = 0.001.) Conclusion: Young males were the most susceptible group to sustain OGIs due to their more physical activities. Health education and safety in the workplace and during sports are crucial to reduce the incidence of OGI.

Preventing occupational chemical eye injuries: important lessons from poison information centres

BACKGROUND

Occupational exposure to hazardous substances is a major public health problem. In the workplace, eye exposures are common and can be a major cause of morbidity and disability. This commentary discusses the role of poison information centres in providing valuable information on the circumstances and causes of these incidents.

OCCUPATIONAL HEALTH SURVEILLANCE

As many eye exposures are easily preventable, there is a need to establish better safety practices in the workplace. Currently, both governments and labour organizations primarily employ injury statistics for the purpose of occupational health surveillance. Identifying risk factors associated with acute exposures in the workplace requires a comprehensive approach using a variety of information resources. Using information from poison information centres can provide invaluable insight into the specifics of the exposure, including the route(s) of exposure, the substances involved and the cause of the exposure.

CIRCUMSTANCES OF OCCUPATIONAL EYE EXPOSURES

Exposure to hazardous substances can occur at various time points during work. A prospective study performed by the Dutch Poisons Information Centre showed that cleaning is a high-risk activity for occupational eye exposure. Patients were often exposed to chemical mixtures that frequently contained alkalis or acids.

CHEMICAL EYE INJURIES

Symptoms following eye contact with chemicals can vary greatly depending on factors such as the type and concentration of the substance(s) involved, the duration of exposure and the time and duration of irrigation (first-aid measure). Eye contact will usually cause irritation, but in more severe cases, chemical burns will result. Recent studies demonstrate that occupational eye exposures often result in only relatively mild symptoms, such as pain, redness, lacrimation or temporary loss of vision. More severe symptoms, such as corneal abrasion, were reported rarely, which may be explained by prompt eye irrigation.

ROOT CAUSES OF OCCUPATIONAL EYE EXPOSURES

To control risks to workers, a hierarchy of prevention and control measures has been established, which employers must take. If elimination or substitution of the dangerous substance is not possible, the exposure can be prevented or reduced by taking organizational (e.g., providing work instructions), technical (e.g., ventilation) and personal (e.g., wearing personal protective equipment) measures. The study performed by the Dutch Poisons Information Centre showed that organizational factors (such as lack of work instructions) and personal factors (such as time pressure and fatigue, and not (adequately) using personal protective equipment), were the main causes of occupational eye exposure.

CONCLUSIONS

Poison information centres provide valuable information that can be used to develop prevention strategies to reduce the number of acute occupational exposures in the future. A multidisciplinary approach is essential to ensure that these preventive measures are actually applied in practice. Therefore, all organizations involved (including governments, labour organizations, medical professionals, occupational physicians, occupational hygienists, safety experts and poison information centres) must work closely together.

Eye Care Behaviors among Adults in Poland: A Nationwide Cross-Sectional Survey

Implementation of eye care behaviors may reduce the risk of eye symptoms and diseases. This study aimed to assess eye care behaviors and identify factors associated with eye care practices among adults in Poland. This cross-sectional survey was carried out between 9 and 12 December 2022 on a nationwide random quota sample of adults in Poland. The study questionnaire included a set of questions on 10 different eye care behaviors. The study population included 1076 participants with a mean age of 45.7 ± 16.2 years, and 54.2% of participants were females. The most common (30.2%) eye care behavior was the use of good lighting indoors, and 27.3% used sunglasses with a UV filter. More than one-fifth of participants declared taking regular screen breaks and limiting screen time. Less than one-tenth of participants used dietary supplements with lutein, beta-carotene, or zinc. Out of 12 factors assessed in this study, self-reported knowledge of eye diseases was the most important factor associated (p < 0.05) with eye care behaviors. There were no economic or educational gaps (p > 0.05) in the implementation of most of the eye care behaviors among adults in Poland. This study revealed a low level of implementation of eye care behaviors among adults in Poland.

Characteristics of Grape Shelf Eye Injuries at Vineyards in Japan

We aimed to investigate the characteristics and visual outcomes of farm work-associated eye injuries at vineyards. We retrospectively reviewed medical charts of patients with farm work-associated eye injuries. The eyes were divided into two groups according to the type of farming that contributed to the eye injury: the vineyard and other farming groups. Injury types, surgical procedures, and changes in visual acuity were statistically evaluated. After initial treatment, patients were followed up at different periods. We examined 30 eyes, including 14 eye injuries in the vineyard group and 16 eye injuries in the other farming group. The mean age of the patients was 58.8 ± 16.7 years, and 83.3% were male. None of the patients wore any safety eyewear at the time of injury. After initial treatment, the mean best-corrected visual acuity significantly improved from 0.83 ± 0.94 at baseline to 0.30 ± 0.57 at the final follow-up (p = 5.8 × 10^-4). Eye injuries in the vineyard group were mostly caused by the penetration of wires of grape shelves and were frequent from winter to spring. We concluded that farm work-associated eye injuries at vineyards have characteristic properties compared with those during other farm work. The use of safety eyewear is strongly recommended to prevent eye injuries during farm work.

COVID-19 Changed Prevalence, Disease Spectrum and Management Strategies of Ocular Trauma

The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the health of people around the world and has reshaped social behaviors and clinical practice. The purpose of this perspective is to provide epidemiologists and clinicians with information about how the spectrum of ocular trauma diseases changed, as well as to optimize management for improving patient prognosis during this crisis. Analysis of current studies revealed that the prevalence of eye trauma decreased overall, with a trend of delayed medical treatment during the COVID-19 era. Irregular epidemic prevention and control measures, unprotected home activities, and unusual mental states are the main causes of ocular trauma. Strategies for reducing morbidity are also discussed, including popularizing the use norms of prevention and control supplies, taking heed to the safety of family activities, highlighting the special status of child protection, and paying attention to previous case data to implement region-specific precautions. The procedure of ophthalmological emergency and outpatient management should also be optimized, and mental health should be emphasized during this pandemic.
