One such condition, dry eye disease (DED), is a multifactorial disorder that significantly impacts patients' quality of life, with prevalence rates ranging from 5% to 50% and higher incidence in women. DED involves tear film instability, inflammation and neurosensory abnormalities, making its management challenging due to diverse underlying mechanisms. Conventional treatments typically focus on symptom relief, but new approaches targeting the disease's pathogenesis are emerging. Alpha-lipoic acid (ALA) is gaining attention for its potential in treating OSD and DED. ALA acts as a potent antioxidant, neutralizing reactive oxygen species. It protects cell membranes by interacting with vitamin C and glutathione, potentially recycling vitamin E. Its antioxidative properties are particularly relevant in meibomian gland dysfunction, a condition implicated in DED. By scavenging free radicals and modulating redox status in the meibomian glands, ALA can reduce oxidative damage, preserve glandular function and decrease inflammation. In diabetic patients with DED, ALA administration has been found to improve tear film parameters, reduce corneal defects, enhance antioxidant status and potentially prevent diabetic retinopathy and keratopathy. Its therapeutic effects on neurosensory abnormalities, especially in diabetic polyneuropathy and other neuropathies, are primarily due to its antioxidant, anti-inflammatory and metal-chelating properties.

Clinically, GACR is characterized by the concentric loss of visual fields due to progressive chorioretinal atrophy. Because OAT is systemically expressed, it is not clear why primarily the retina is damaged in GACR patients. In this review, we first provide an extensive overview of the clinical features and current treatment modalities for GACR. Next, we discuss the different pathways involved in ornithine metabolism, including the urea cycle, polyamine synthesis, creatine synthesis, proline synthesis and degradation and provide our vision on how OAT deficiency is thought to affect these pathways in the retinal pigment epithelium (RPE). We provide several hypotheses to explain the retinal pathology observed in GACR and discuss perspectives on future research.</p>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
