Occupational diseases are a major global concern. Firefighting is associated with numerous health hazards. However, the ocular problems that fire fighters endure are understudied. The purpose of this study was to determine conjunctival disorders and other ocular morbidities prevalent among fire service personnel in the Kumasi Metropolis of Ghana.A cross-sectional study was conducted in all five fire stations in the metropolis. A total of 150 personnel aged 20 to 60 years were examined. Comprehensive ocular examination was carried out which included ocular and occupational history, visual acuity measurement, ophthalmoscopy and visual field test by confrontation. The Statistical Package for Social Scientists (SPSS) version 16.0 was used to analyze the data. The tool employed was descriptive statistics and Chi- square test was used to find out significant differences between comparable categorical groups.

Out of the 150 personnel, 66.7% were male and 33.3% were female. The common ocular diseases were pinguecula (21.3%), pterygium (15.3%), allergic conjunctivitis (8.0%), dry eyes (5.3%) and retinal abnormalities (4.0%). The prevalence of ocular morbidities among the fire service personnel was 57.3%. Ocular diseases were found to be more prevalent among males (40.7%) than females (16.7%). Conjunctival disorders significantly increased with longer duration of service, but no significant association was found for non-conjuctival disorders.The study revealed a high ocular morbidity rate in the fire service personnel and underscores the need for regular screening procedures and strategies to identify and manage non-blinding conditions that interferes with productivity as well as potentially blinding conditions among personnel for timely intervention.

Some occupations are known to have serious harmful impact on health. Over a million workers in the UK suffer a health condition caused or worsened by their work. Occupational diseases like firefighting have an immediate adverse effect on work efficiency and productivity. Firefighting poses serious risks including ocular hazardsto personnel. People involved in occupations like firefighting, mining and construction sufferserious health conditions including cardiovascular disorders, musculoskeletal disorders, sleep disorders and traumatic injuries that could lead to sudden deaths Ocular morbidity can be referred to as the relative incidence of eye diseases. It can also be defined as a disease state, disability or poor health due to eye diseases. Fire service personnel in performing their duties face danger from exposure to smoke, dust, extremely high temperatures (1200°C to 1400°C) and issues surrounding personal protective equipment, all of which pose a threat to their ocular health. Occupation-related eye conditions contribute to the global statistics of ocular morbidity and the prevalence of such conditions among workers especially firemen can affect work output or productivity. 

Investigating the occupational association of eye diseases will increase knowledge about how these diseases are related to occupations and inform strategic planning and implementation of policies to prevent or minimize the risks and occurrence of these occupational disorders, which could increase health and productivityFirefighting has become very important in the Kumasi Metropolis of Ghana over the past few years. In 2015 alone, the Kumasi Central Market suffered not less than five major fire outbreaks, each of which required several hours of intense firefighting by fire service personnel to be quenched. Within the first week of January 2016, there had been three major fire outbreaks in suburbs such as Aboabo and Adum, notwithstanding minor household fires and burning accident vehicles on the Kumasi-Accra highway. Personal communication with firefighters and common observation has revealed that most firefighters wear protective clothing but not goggles in their line of work. This exposes their eyes to intense heat, smoke, dust, exhaust particles and soapy liquids that comes with regular firefighting. 

This study was done to determine ocular morbidities prevalent among fire service personnel in the Kumasi Metropolis of Ghana. Data from this study will create awareness among the fire personnel locally and globally and also aid in policy formulation.A descriptive cross-sectional study was conducted among fire service personnel in the Kumasi Metropolis, Ghana. There were five fire stations with a total population of 294. The sample size for the study was calculated to be 135 using Epi Info version 7.1.5.2 (expected frequency 20.3%, 5% limits, 95% confidence level). A total of 150 fire personnel were studied for various ocular morbidities between 7th July and 8th August, 2014. In each of the stations, the subjects were registered with a structured questionnaire administered by one of the researchers in the local (Twi) language. The questionnaire was used to obtain data on the personal, medical and occupational information of the personnel. A battery of eye examinations namely visual acuity measurement, external eye examination and fundoscopy were carried out on all subjects using Snellen’s chart (6metres), pentorch and ophthalmic loupe, and Welch Allyn Direct Ophthalmoscope. Visual field test by confrontation was also carried out for all participants. All examinations findings were detailed on structured record forms and cross-checked for completeness of data before each subject was discharged. Diagnoses were made on the presence of a condition in one or both eyes of a study subject.
