“…It is however contrary to the report of Ichiro 24 who reported a higher prevalence of pterygium among welders in Japan. Differences in succeptibility and additional climatic differences have also been proposed as possible explanations for this variation 23 Pterygium was the second common eye disorder among the welders in this study with a prevalence of 17.5%.…”

Background: Welders have been identified as a high risk group for eye disorders due to their exposure to ultraviolet radiation. Objective: To determine the prevalence and types of eye diseases amongst welders in Ile-Ife, Osun state. Methods: This is a cross sectional descriptive study of 405 consenting welders. Information on socio-demographic characteristics was obtained using a pre-tested proforma and all subjects had visual actuity test, anterior and posterior segments examination, test of stereopsis and macular function. Results: Two hundred and seventy five (67.9%) of the respondents were arc welders, 99(22.5%) were gas welders while 39(9.6%) utilized both welding techniques. The age of the respondents ranged from 16 years to 80 years with a mean of 38 ± 13 years. Conjunctival degenerative disorders like pingueculum (50.1%) and pterygium(17.5%) constituted the commonest eye disorders among the welders. There were 6 blind eyes of 5 welders with pigmentary maculopathy accounting for the single case of bilateral blindness. There is a greater odd in developing pingueculum and Pterygium (OR=1.015, 1.039 respectively) in arc welders than in gas welders. Conclusion: Pingueculum, Pterygium, corneal opacity, and pigmentary macular deposits were the common eye disorders among welders.

“…Although chronic irritation and inflammation occurring at the ocular surface may contribute to pterygium development, intracellular damage accruing from ultraviolet exposure is the most important etiology. [2][3][4][5][6] It is known that ultraviolet radiation is mutagenic for the p53 tumor suppressor gene and can elicit DNA mutation and activate transcription factors, such as AP-1 and NF-kB, leading to the induction of collagen-degrading metalloproteinases. 7,8 Pterygium usually arises in the superficial layers of the nasal cornea and can seriously compromise vision if it encroaches on the visual axis.…”

“…Nonmelanoma skin cancer (NMSC) was reported to occur in welders who were exposed to intense ultraviolet irradiation (Currie and Monk 2000;Young 1994). That UVR from arc welding causes injuries in the workplace has been well documented and diseases from arc welding have been noted in some welders (Doughty and Oblak 2005;Magnavita 2002;Fich et al 1993;Norn and Frank 1991;Power et al 1991;Brittain 1988;Cellini et al 1987;Karai and Horiguchi 1984;Emmett et al 1981).…”

This study established a comprehensive approach to monitoring UVR magnitude from Shield Metal Arc Welding (SMAW) processing and quantified the effective exposure based on measured data. The irradiances from welding UVR were calculated with biological effective parameter (Slambda) for human exposure assessment. The spectral weighting function for UVR measurement and evaluation followed the American Conference of Governmental Industrial Hygienists (ACGIH) guidelines. Arc welding processing scatters bright light with UVR emission over the full UV spectrum (UVA, UVB, and UVC). The worst case of effective irradiance from a 50 cm distance arc spot with a 200 A electric current and an electrode E6011 (4 mm) is 311.0 microW cm(-2) and has the maximum allowance time (Tmax) of 9.6 s. Distance is an important factor affecting the irradiance intensity. The worst case of the effective irradiance values from arc welding at 100, 200, and 300 cm distances are 76.2, 16.6, and 12.1 microW cm(-2) with Tmax of 39.4, 180.7, and 247.9 s, respectively. Protective materials (glove and mask) were demonstrated to protect workers from hazardous UVR exposure. From this study, the methodology of UVR monitoring in SMAW processing was developed and established. It is recommended that welders should be fitted with appropriate protective materials for protection from UVR emission hazards.
