Indole-3-Propionic Acid Bridges Gut Dysfunction and Diabetic Retinopathy — A Biomarker and Therapeutic Avenue

Indole-3-Propionic Acid Bridges Gut Dysfunction and Diabetic Retinopathy — A Biomarker and Therapeutic Avenue

A Gut 2025 study identifies microbially produced indole-3-propionic acid (IPA) as a protective metabolite linking restored intestinal tryptophan handling to prevention of diabetic retinopathy in mice and associates low serum IPA with retinopathy in people with type 2 diabetes.
Glucagon-Like Peptide-1 Receptor Agonists and Ocular Risks: A Comprehensive Review of Neovascular AMD, Diabetic Retinopathy, and Ischemic Optic Neuropathy in Diabetes

Glucagon-Like Peptide-1 Receptor Agonists and Ocular Risks: A Comprehensive Review of Neovascular AMD, Diabetic Retinopathy, and Ischemic Optic Neuropathy in Diabetes

GLP-1 receptor agonists used in diabetes show a twofold increased risk of neovascular AMD, a modest risk elevation for diabetic retinopathy, and a small but significant increased risk for nonarteritic anterior ischemic optic neuropathy, warranting careful ophthalmic monitoring.
Acute Angle Closure Incidence in a Large Countywide Safety Net Teleretinal Screening Program: Safety of Pharmacologic Dilation in Diabetic Retinopathy Screening

Acute Angle Closure Incidence in a Large Countywide Safety Net Teleretinal Screening Program: Safety of Pharmacologic Dilation in Diabetic Retinopathy Screening

This review synthesizes evidence on the incidence of acute angle closure (AAC) following pharmacologic pupillary dilation in a large teleretinal screening program, confirming the very low risk and supporting dilation safety in diverse populations.
