The association linking corticosteroid therapy with the development of posterior subcapsular cataracts has been well documented. These drugs are widely used therapeutically, principally to capitalize on their ability to inhibit inflammatory responses. The literature on corticosteroid-induced posterior subcapsular cataracts is reviewed here. Data from the previously published series and individual lens susceptibility to corticoids do not allow the establishment of a direct factor relating cataract formation to corticosteroid dose and the duration of therapy; however, significant progress has been made in elucidating the mechanism by which corticoids bring about the development of these opacities. Exploration into the development of these lesions has shed light on the similarities these opacities share with other cataracts, especially with regard to location and pathogenesis.
Non-pharmacological approaches to remedy CINV typically involve small lifestyle alterations, such as using unscented deodorants and soaps, avoiding strong scents altogether, and dietary modifications such as eating several small meals throughout the day, eating high-protein, high-calorie food, drinking lots of clear liquids, and removing spicy, fatty, fried, or acidic foods from the diet.  Patients may also participate in alternative practices such as self-hypnosis , relaxation and imagery therapy, distraction, music therapy , biofeedback , desensitization , or accupressure .
