A cross-sectional ophthalmological survey to determine the occupational hazards of stone quarry and stone processing industry workers in Abakiliki from an ophthalmic perspective. The central mine and the stone processing plant at the stone crushers enterprise were used for the survey. Administrative staff and non-technical workers were excluded from the study. A total of 384 workers comprising the sample size drawn by a two stage stratified sampling technique were studied. The ophthalmic needs of these workers were identified with a view to improving eye safety and productivity at work. A total of 298 had some form of ocular disorder (refractive and non refractive), giving a prevalence of 77.60%. The six commonest eye disorders seen in descending order were pterygium (37.89%), refractive error (19.53%), Conjunctivitis(13.67%), pingueculum(7.62%), Cataract(6.45%) and Presbyopia(4.96%). Others were glaucoma, optic atrophy, cicatrical ectropion, lid scars etc. A total of 9(2.34%) workers were seen with monocular blindness. A total of 172(45.1%) of the workers admitted a past history of injury while at work; 59(32.5%) of which were blunt in nature. Of these cases of injury, 140(36.5%) involved the eye. The common agents of injury identified were fragments of stone, stone dust, fire from explosive, smoke from explosive, all of which could be prevented by wearing appropriate protective eye coverings. Industrial injuries accounted for unilateral loss of vision in 2(0.52%) of these workers. One of the risk factors identified is environmental exposure following non-use of eye protective devices. An overwhelming majority of the workers 379(98.7%) did not use eye protective devices. To prevent the occurrence of work related accidents and to improve the ocular health status of these workers, it is recommended among others that the following be done-: provision of adequate and regular ophthalmic services within the industry, provision of suitable eye protective devices and enforcement of their use and modification of certain industrial processes/activities to limit the risk of eye injury.
