 Chronic ocular diseases can cause severe visual impairment and even blindness if left untreated. To address this issue, researchers have been developing novel drug delivery systems to provide sustained and effective treatment. These include implantable drug delivery systems, IDDS, which are designed to deliver drugs over a longer period of time compared to traditional drug delivery methods. IDDS offer advantages such as consistent drug release, minimal side effects and the ability to bypass ocular barriers. Despite these benefits, further development is needed to ensure safe and effective use of IDDS. This article was authored by Mahmood Mostafa, Adele Al-Fatiz, Ray Geolani and others.
