Abstract
Introduction: Vision remains a defining character of our interaction within society and loss of this sense can be devastating to the individual. Eye injuries are common and of global concern. An important world-wide public health problem is ocular trauma. In India the impact of trauma on visual acuity is particularly important because of the repercussions on the socio-economic status of the individual and the family. The personal impact of ocular injury is difficult to define, although the lifestyle of the affected individual may be permanently altered. Ocular trauma is a result of the redistribution of kinetic energy to the various ocular structures. This is a force that can disturb any organic or inorganic substance. The extent of ocular injury depends on the nature of trauma, extent of damage to the intraocular structures, presence of intraocular foreign body, and the site of injury. Aim: The overall aims of this study were to: 1. To document the pattern of ocular injuries among quarry workers in quarries around Vellore. 2. To evaluate the efficacy of protective eyewear in reducing ocular injuries. 3. To evaluate the durability of protective eyewear 4. To enhance the acceptance of protective eyewear among quarry workers using educational interventions. For this last aim, a pragmatic cluster randomized trial was designed to compare the effectiveness of enhanced educational interventions over a simpler educational procedure. The unit of randomization were quarries and this cluster design was chosen to prevent contamination of educational interventions between quarries. Discussion: Indian data on prevalence of ocular injuries among quarry workers is scarce and there is no published study on the result of any preventive intervention. In this regards we didn’t have any comparison to make with our study. Most of the workers were males as compared to females Conclusions: Mandatory provision of protective eyewear by the employers to the quarry workers and ensuring their continual usage may go a long way in reducing ocular injuries. Longer periods of follow up would determine the long term acceptability of protective eyewear, the frequency with which they need to be replaced and the continued effectiveness of this strategy in prevention of ocular injuries in stone quarry workers.
