Firework-related Ocular Injuries During Festival Season: A Hospitalbased Study in a Tertiary Eye Care Center of Nepal

Local Firework Restrictions and Ocular Trauma

Importance

Fireworks can cause vision-threatening injuries, but the association of local legislation with the mitigation of these injuries is unclear.

Objective

To evaluate the odds of firework-related ocular trauma among residents of areas where fireworks are permitted vs banned.

Design, Setting, and Participants

This case-control study was conducted at a level 1 trauma center in Seattle, Washington, among 230 patients presenting with ocular trauma in the 2 weeks surrounding the Independence Day holiday, spanning June 28 to July 11, over an 8-year period (2016-2022).

Exposures

Firework ban status of patient residence.

Main Outcomes and Measures

Odds of firework-related injuries among residents of areas where fireworks are legal vs where they are banned, calculated as odds ratios (ORs) and 95% CIs.

Results

Of 230 consultations for ocular trauma during the study period, 94 patients (mean [SD] age, 25 [14] years; 86 male patients [92%]) sustained firework-related injuries, and 136 (mean [SD] age, 43 [23] years; 104 male patients [77%]) sustained non-firework-related injuries. The odds of firework-related ocular trauma were higher among those living in an area where fireworks were legal compared with those living in an area where fireworks were banned (OR, 2.0 [95% CI, 1.2-3.5]; P = .01). In addition, the odds of firework injuries were higher for patients younger than 18 years (OR, 3.1 [95% CI, 1.7-5.8]; P < .001) and for male patients (OR, 3.3 [95% CI, 1.5-7.1]; P = .004). Firework injuries were more likely to be vision threatening (54 of 94 [57%]) compared with non-firework-related injuries (54 of 136 [40%]; OR, 2.1 [95% CI, 1.2-3.5]; P = .01).

Conclusions and Relevance

This case-control study suggests that the odds of firework-related ocular trauma were slightly higher among residents of areas where fireworks were legal compared with residents of areas where fireworks were banned. Although these results suggest that local firework bans may be associated with a small reduction in the odds of firework-related ocular trauma, additional studies are warranted to assess what actions might lead to greater reductions.

TFOS lifestyle: Impact of societal challenges on the ocular surface

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.
