Methylenetetrahydrofolate reductase gene polymorphisms in patients with nephrotic syndrome.

Neuropathic corneal pain (NCP) is a debilitating condition resulting from corneal nerve damage or dysfunction, leading to persistent ocular pain, discomfort and hypersensitivity. Conventional therapy with eye drops often provides inadequate relief, necessitating the need for alternative therapeutic approaches. This review explores the role of electrotherapy in managing NCP, including its mechanisms, clinical efficacy, and potential integration into multimodal treatment strategies. We examine current evidence on various electrotherapy modalities such as transcutaneous electrical nerve stimulation, neurostimulation, and microcurrent stimulation. These electrotherapies have the potential to modulate pain pathways, promote nerve regeneration, and restore corneal homeostasis. Emerging studies suggest electrotherapy may alleviate NCP by altering neural signaling and reducing hyperalgesia. Integrating electrotherapy into existing pain management strategies may enhance the outcomes for patients with refractory NCP. However, its clinical application remains limited by a lack of standardized protocols and robust clinical trials. Although electrotherapy presents a promising and non-invasive option for NCP management, further research is needed to optimize the treatment parameters and optimal duration, assess the long-term efficacy, and establish guidelines for clinical use.
