Primary prevention of ocular injury in agricultural workers with safety eyewear

Pattern and clinical profile of patients with ocular trauma presenting to the emergency department of a teaching hospital in India: A prospective observational study

OBJECTIVES

One major contributor to avoidable ocular morbidity is ocular trauma (OT). The study aimed to document the epidemiological factors, pattern of injury, and outcome among patients with OT presenting to the emergency department (ED).

METHODS

This was a prospective observational study conducted in the ED of a tertiary care teaching hospital in Eastern India after due approval from the institutional ethics committee. The data were collected during the period from March 2021 to February 2022. Data pertaining to age, sex, type of injury, mechanism of injury, time and place of injury, details of tissue involvement, visual acuity, any prior history of injury, initial diagnosis, and management were noted. To estimate the severity of the injury and the probable visual outcome, we calculated through OT score (OTS), including one raw score and OTS. Statistical analysis was performed using the R, version 4.6.1.

RESULTS

A total of 180 patient's data were included for final analysis. The median (interquartile range) age of the patients was 32 (24-45) years. The majority were males (n = 147 [81.6%]) with a male-female ratio of 4.5:1. Road traffic accidents (RTA) were the common cause of injury (n = 122 [67.7%]). Unilateral eye involvement was the most common (n = 147 [81.6%]). In the pattern of injury, most of the patients sustained closed globe injuries (CGIs) (n = 158 [87.7%]). Among the CGIs, injury to the ocular adnexa and conjunctiva (n = 141 and 127, respectively) was the most common. Injury to the retina and choroids occurred in 20 (11%) patients. The vision was not affected in most of the cases (n = 125 [69.4%]) with a visual acuity of > 6/18. The majority (n = 120 [67%]) of the patients had an OTS of grade-4, followed by grade-2 (n = 22 [12%]). Most of the patients required only medical management (n = 100 [56%]), whereas 77 (43%) patients required surgical interventions.

CONCLUSION

OT was a common presentation in the ED. Male patients with monocular injuries involved in RTAs were mostly affected. The vision was preserved in most of the cases.

Risk factors for corneal abrasions in Nepal: a community-based study

BACKGROUND

South Asia is experiencing rapid urbanization, which may be changing the risk factor profile for ocular trauma. The objective of this study was to compare risk factors for traumatic corneal abrasions in rural versus urban Nepal, and to assess if any risk factors were associated with a poor outcome.

METHODS

In a prospective, cross-sectional, community-based study performed as part of a cluster-randomized trial, community health workers from Nepal were trained to diagnose and treat traumatic corneal abrasions. Participants with an abrasion were invited to complete a risk factor survey. The main exposure variable was the object of eye injury, stratified by rural-urban residence. The main outcome measure was a lack of corneal healing after a three-day course of antimicrobials.

RESULTS

Of 3657 participants diagnosed with a corneal abrasion, 2265 completed a survey. Eye trauma occurred most frequently during agricultural activities. The most common object of injury was vegetative matter, accounting for approximately 40% of injuries in rural, peri-urban, and urban communities. Wood injuries were more common in rural communities (24%) compared with urban or peri-urban communities (13%). Eye injury from an animal was more likely to result in a non-healing corneal abrasion after 3 days of treatment compared with other types of trauma (prevalence ratio 2.59, 95%CI 1.16-5.76).

CONCLUSIONS

Health promotion activities for prevention of corneal ulcers in Nepal should focus on agricultural trauma in both rural and urban areas. Community members experiencing eye trauma from an animal may benefit from early referral to an eye clinic.

Intraocular foreign body: Characteristics, visual outcomes, and predictive values of ocular trauma score

Introduction

Retained intraocular foreign body (IOFB) remains an important cause of acquired visual impairment. The visual prognosis following treatments for eyes with retained IOFB was observed to be distinct from other mechanisms of open globe injury due to the specific nature and associated circumstances. This study evaluated the risk behaviors, visual results, and predictive values of Ocular Trauma Score (OTS) in determining visual outcomes in patients with IOFB that were not related to terrorism.

Methods

Medical records of patients who underwent surgical interventions between January 2015 and December 2020 were retrospectively reviewed.

Results

A total of one hundred and sixty-one patients (162 eyes) were recruited. The patients had a mean (standard deviation) age of 47.6 (14.0) years with working male predominance (93.2%). The majority of patients were injured by activities related to grass trimming (63.4%) and metallic objects were the main materials causing injuries (75.7%). Following treatments, the proportion of eyes having vision worse than 20/400 decreased from 126 eyes (77.8%) to 55 eyes (33.9%) at final visit. Ocular trauma score (OTS) had a high potential prediction for final vision in eyes in OTS categories 4 and 5. However, the discordance of final visual acuity distribution was observed in some subgroups of eyes in OTS categories 1 to 3.

Conclusion

This study highlights the significance of IOFB related eye injuries in a tertiary care setting. Decision making on treatments should be carefully considered, particularly in eyes in lower OTS categories, in light of a rise in the proportion of patients who experience improved vision after IOFB removal.

International Globe and Adnexal Trauma Epidemiology Study (IGATES): Visual outcomes in open globe injuries in rural West India

BACKGROUND/OBJECTIVES

To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries (OGIs) in a rural population using the International Globe and Adnexal Trauma Epidemiology Study (IGATES) online registry.

SUBJECTS/METHODS

Retrospective cohort study of patients with OGI. OGIs were identified from the IGATES database at a tertiary referral eye care centre in rural West India over a period of 12 years. Patient demographics, clinical and pre-operative factors affecting final visual outcome was evaluated.

RESULTS

A total of 791 eyes with OGIs were included in data analysis. 11 eyes that were lost to follow-up and 12 eyes with incomplete data were excluded. Most of the patients were male (559, 70.6%) and mean age of all patients was 23.9 years ± 19.4 years. Occupational hazards (including domestic housework) (307, 38.8%) and leisure play (324, 41.0%) were the leading causes of OGI. The most common mechanism of injury was being struck by a wooden stick (250, 31.6%). Univariate analysis of pre-operative variables showed initial visual acuity (VA), zone of injury, size of wound, structures involved in the injury and presence of infection were significant prognostic factors for worse final visual outcome (p < 0.001). Multivariate analysis showed VA ≤ 3/60 or worse at presentation had statistically significantly higher odds ratio of ending up with worse visual outcomes (p < 0.012).

CONCLUSIONS

Males in working age groups suffer from OGIs more frequently, usually from agricultural and pastoral activities. Initial VA, zone 3 injuries, corneoscleral wound, large wound size and presence of post-traumatic infections are significant prognostic factors.

Trends in Workplace-Related Eye Injuries in the United States From 2011 Through 2020

Purpose

To provide insight into the current scope of workplace-related eye injuries (WREIs) by describing the demographic profiles and causes of WREIs from the years 2011 through 2020.

Methods

The US Bureau of Labor Statistics (BLS) dataset on WREIs injuries was used. Descriptive data generated included the frequency of eye injuries, the setting, and demographic data.

Results

The BLS reported an estimated 237 590 WREIs in the study timeframe. In that time, the incidence fell from 2.4 to 1.7 per 10 000 workers. These injuries commonly occurred in men (77.1%), White individuals (36.3%), those aged 25 to 34 years (26.9%), and those in the service (23.0%) and production (18.5%) industries. On average, WREIs resulted in a median of 2 missed workdays, with only 5.0% missing more than 1 month of work. Between 2019 and 2020, there was a 15.6% reduction in total WREIs in the US but a 39.3% increase in WREIs among healthcare workers.

Conclusions

Men, White individuals, and younger workers might be at increased risk for WREIs. Public health interventions targeted toward improving access to and the quality of protective equipment in these groups and in fields involved in the primary or secondary sectors of industry and healthcare might be the most cost-effective measure to reduce the impact of WREIs on the US workforce.

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.

Role of Socioeconomic Status (SES) in Globe Injuries: A Review

Globe injury is a serious worldwide public health issue frequently leading to permanent vision impairment. The plethora of different types of globe injuries is classified into categories, including open and closed globe injuries. Globe injury occurs mainly in the workplace and at home, affecting predominantly middle-aged working men. Socioeconomic status (SES) is defined by income level, educational attainment, and employment status. Low socioeconomic status has been associated with a higher incidence of globe injury and can be utilized to identify at-risk populations. For managing open and closed globe injuries, different strategies are applied and the implementation of adequate globe injury prevention measures is needed for reducing the occurrence of globe injury. The following article aims to provide an overview of globe injury characteristics and their correlation with socioeconomic status and to highlight the significance of considering SES as a variable in globe injury prevention.

Removal of full-thickness vertical corneal stromal wooden foreign bodies: An innovative ab-interno technique

A 28-year-old male presented with three full-thickness stromal wooden foreign bodies vertically oriented in the left cornea. An innovative intracameral approach was used. Paracentesis was done and healon was injected into the anterior chamber. Iris repositor was introduced into the anterior chamber and the area of foreign bodies was pushed up to compress the stroma. The wooden foreign body projected above the corneal surface and were picked up one by one using McPherson forceps. One of the foreign bodies has penetrated through the Descemet‘s membrane resulting a corneal perforation. A corneal perforation was confirmed by observing egress of the irrigating solution, injected into the anterior chamber through the paracentesis opening. The corneal perforation was sealed with corneal glue. He achieved 6/9 BCVA (OS) at 8 weeks and maintained it during18 months follow-up.

Relationship between the use and type of eye protection and work-related corneal and conjunctival foreign body injuries

OBJECTIVE

This study was designed to reveal the relationship between the use and type of eye protection and the occurrence of work-related corneal and conjunctival foreign body injuries.

METHODS

This is a retrospective cohort study of patients with work-related corneal and/or conjunctival foreign body injuries between 1 August 2017 and 31 July 2018. They were all diagnosed and treated at Jia Ding Hospital affiliated to the Shanghai University of Medicine and Health Sciences in Shanghai, China. All patients received a comprehensive eye examination and a face-to-face interview using a structured questionnaire by ophthalmologists.

RESULTS

A total of 426 consecutive patients were included in the study. The majority of work-related eye injuries occurred in men (94.17%). Summer was the season that had the highest incidence of eye injuries, especially in July and August (38.03%). There were 290 patients (68.08%) that were injured more than once. The ratio of eye protection use to non-protection was 1:7 at the first time of eye injury. The ratio improved to 1:3 on subsequent injury. A majority of employers (79.11%) provided eye protection to employees. However, 19.95% of the workers were injured despite wearing a pair of protective spectacles. The causes of work-related eye injury were as follows: no eye protections provided (20.89%); unawareness of work safety (30.99%); defect of spectacles (47.18%).

CONCLUSIONS

Protection use at work effectively prevents work-related eye injuries. Both employers and employees require improved awareness of workplace hazards and personal protection. Eye protection should be selected appropriately according to the work environment.

Epidemiology of Eye Injuries Resulting in Hospitalization, a Referral Hospital-Based Study

Purpose

To determine the characteristics of hospitalized eye injuries in Northern Thailand, a tertiary referral center.

Methods

The medical records of patients who sustained an eye injury and were admitted to the Department of Ophthalmology, Chiang Mai University, Thailand, from February 2015 to February 2016 were retrospectively reviewed. Demographics and characteristics of each injury were collected.

Results

A total of 249 injured patients were included, of which 227 (91.2%) were male. There was no significant difference in the mean (standard deviation) age between genders, 39.8 (22.9) years of age for females and 43.8 (17.8) for males (P = 0.43). Most injuries occurred in the workplace (149/249, 59.8%). Nearly similar proportions of the opened globe and closed globe injuries were observed, 121/249 (48.6%) patients and 109/249 (43.8%) patients. A small proportion sustained eyelid/adnexal and chemical injury, 19/249 (7.6%) patients. Corneal penetration (52/249, 20.9%) and intraocular foreign body (37/249 14.9%) were the most prevalent conditions for opened globe injury. Traumatic lens subluxation/dislocation (31/249, 12.4%) and a traumatic corneal ulcer (25/249, 10.1%) were the common conditions for closed globe injury. A delayed presentation to the hospital was noted in closed globe injury. The eyelid/adnexal injury group had a better final visual acuity compared to the opened and closed globe injury group.

Conclusion

Activities related to hospitalized eye injuries were varied in different age groups, specifically adults at workplace, and children at playground; therefore different strategies should be applied to prevent visual impairments and disabilities in specific high-risk groups.
