Lightning-induced cataract with concomitant optic nerve damage

Lightning-induced ocular injuries are rare but potentially severe sequelae. This case report describes a 35-year-old male patient who suffered a lightning strike injury 20 years ago, resulting in traumatic cataract and optic nerve damage in his left eye. When the patient presented for consultation, he exhibited a significant decrease in left eye visual acuity. Detailed ophthalmic examinations and auxiliary tests confirmed the presence of cataract and optic nerve impairment. The patient underwent left eye phacoemulsification cataract surgery and intraocular lens implantation, leading to improved visual acuity and posterior segment conditions. However, this case highlights the complexity and therapeutic challenges of lightning-induced cataract with concomitant optic nerve damage. The discussion addresses the mechanisms of optic nerve damage following lightning strike and underscores the importance of early intervention. This report emphasizes the significance of assessing optic nerve function in lightning strike patients and provides new perspectives for related research and treatment.
