电光性眼炎是眼表层組織受富于紫外綫的輻射能照射后所引起的一种非生物反应(Abiotic Reaction),任何接触紫外綫的工作,如不注意保护,皆可发生,最常見的是由电焊弧光引起的。在各种类型的机器制造工业和机械加工工厂中,特别是机械安装和金属結构企业,由于广泛的利用电气熔接金屬,这种职业眼病的发病率是颇高的,此外电爐炼鋼的电弧光,石英水銀灯及高压电流短路的照射亦可引起本病。在我們的門診病例中有三例(医学生,护士及修理工),在石英水銀灯下工作时未注意眼睛的保护而发生。又有二例电工,由于关閉高压电流的开关(380伏特)时形成短路而引起本病。
Electro optic ophthalmia is a non-biological reaction (Abiotic Reaction) caused by exposure to ultraviolet radiation in the ocular surface tissues. Any exposure to ultraviolet radiation can occur without protection. The most common one is caused by Welding arc caused. In various types of machinery manufacturing and machining factories, especially in machinery installation and metal structure enterprises, the incidence of such occupational ocular diseases is quite high due to the extensive use of electrofusion metal. In addition, electric arc furnace steelmaking arcs Light, quartz mercury lamps and high-voltage short-circuit current can also cause the disease. Three of our outpatient cases (medical students, nurses and mechanics) did not pay attention to eye protection while working under quartz mercury lamps. Two more electricians caused the disease as a result of the short-circuit caused by the switch (380V) turning off the high-voltage current.
