Lightning is a naturally occurring atmospheric phenomenon. Though uncommon, it is a potentially devastating and underreported natural calamity. Lightning accounts for the second leading cause of weather-related death in most parts of the world. Among the survivors of lightning injury, more than half of the victims may suffer from some form of ophthalmic injury. The lightning-associated ocular injury varies from a range of anterior segment to posterior segment pathologies. We report on two clinical cases of ocular injuries among the survivors of lightning injury. Anatomical involvement is seen at different levels with presentation as uveitis, pupillary abnormality, maculopathy, and later development of lenticular opacification. Optical coherence tomography (OCT), a noninvasive diagnostic tool, is particularly useful in the evaluation of lighting maculopathy as well as to monitor its progression through the course of time. Visual prognosis depends upon the structures of the eyes affected in the injury. The presence of irreversible retinal damage as well as optic nerve damage often result in poor visual outcome in the absence of significant anterior segment pathology. This report highlights the evolution of maculopathy through the course of time and signifies the importance of long-term follow-up postlightning injury.
闪电是一种自然发生的大气现象。虽然不常见,但它是一种潜在的毁灭性且未得到充分报道的自然灾害。在世界大部分地区,闪电是与天气相关死亡的第二大主要原因。在闪电伤的幸存者中,超过一半的受害者可能会遭受某种形式的眼部损伤。与闪电相关的眼部损伤范围从一系列前段到后段病变不等。我们报告了两例闪电伤幸存者眼部损伤的临床病例。不同程度可见解剖结构受累,表现为葡萄膜炎、瞳孔异常、黄斑病变以及后期晶状体混浊的发展。光学相干断层扫描(OCT),一种非侵入性诊断工具,在评估闪电黄斑病变以及监测其随时间的进展方面特别有用。视觉预后取决于损伤中受影响的眼部结构。在没有明显前段病变的情况下,不可逆的视网膜损伤以及视神经损伤的存在往往导致视觉预后不良。本报告强调了黄斑病变随时间的演变,并表明闪电伤后长期随访的重要性。
