Methods and Analysis: A descriptive study. The pig head dissection was performed at the abattoir for convenience. The orbital tissue thus obtained was used to set up the wetlab workstation. Results: A cost-effective, low technology, affordable set-up for ophthalmic surgical wetlab protocol was developed. High resolution photographs of the procedure were taken and were presented for ease of description. The dissection protocol was test-run at an ophthalmic surgical training workshop. Conclusions: The porcine orbit and the wetlab setup were available and affordable. The dissection in the abattoir is easy and reproducible. The orbit was used instead of the enucleated globe and this ensures stability throughout surgical practice sessions.展开更多

There is a paucity of data on the profile of ophthalmic disorders in this vulnerable group, especially in developing countries. Aim: We aimed to determine the burden and spectrum of ophthalmic disorders in stone workers in Abakiliki, Nigeria. Methods: In a population-based cross-sectional survey of stone industry workers conducted in Nigeria, between February and April 2012, relevant data from participants were collected. Descriptive and comparative statistics were performed and statistical significance was indicated by p Results: Participants (n = 384;males, 158;females, 226) were aged 32 ± 11.8 SD years (range, 14 - 68 years) and comprised 105 (27.3%) stone quarry workers and 226 (72.7%) stone processing workers. Of these, 298 (77.6%) had some form of ophthalmic disorder, which frequently involved the ocular anterior segment (69.9%) or posterior segment (4.9%). Work-related eye injuries were reported by 36.5% of employees. Leading disorders were anterior segment: pterygium-associated (37.9%). Visual impairment (2.9%) and monocular blindness (1.3%) were reported. The prevalence of eye disorders was not significantly associated with participant socio-demographic or work characteristics. Male gender (p = 0.001) and engagement in stone processing (p = 0.001) were significant predictors of work-related eye injury. Conclusions: Among stone industry workers in Abakaliki, Nigeria, there is a high prevalence of ophthalmic disorders, frequently of the ocular anterior segment, and work-related eye injuries are commonly reported. Occupational eye health education, provision of protective eye devices and appropriate ophthalmic care are suggested.展开更多
