Additionally, radiation exposure, especially from treatments for cancer, is known to induce ASC. It is also associated with diseases such as atopic dermatitis and diabetes mellitus. Furthermore, certain types of eye trauma can lead to the development of ASC. It is important to monitor and manage these risk factors to prevent the progression of cataracts.
