Systemic Medications and Their Effects on the Retina and Choroid: An Updated Review Systemic Drugs and Retinal–Choroidal Effects
Main Article Content
Abstract
This review provides a comprehensive analysis of systemic medications and illicit substances that can lead to various forms of retinal and choroidal toxicity. Accurate diagnosis requires a detailed medication history and the identification of characteristic retinal changes using multimodal imaging techniques. The discussion includes drugs associated with retinal pigment epithelial disruption, vascular alterations, cystoid macular edema, crystalline deposits, drug-induced retinal folds, and uveitis. The ocular effects of emerging chemotherapeutic and immunotherapeutic agents are also examined. Key mechanisms of action, preventive strategies, and available treatment options are explored in detail. The focus is on medications frequently encountered in ophthalmic practice and important considerations for eye care professionals. Many drug-induced retinal toxicities are reversible with discontinuation of the medication, especially when detected early before causing significant visual impairment. However, certain agents may lead to permanent and progressive retinal damage. Close monitoring and timely intervention by ophthalmologists are essential. This review highlights the importance of early detection and proper management of medication-induced retinal and choroidal toxicity to reduce the risk of vision loss and related complications.
