Practice Report — JVIB Extract

Since Practice Reports do not have abstracts, we have provided an extract of the beginning of the text.

Extract: Along with the aging of the population, various comorbidities may arise, such as arthritis, hypertension, and erectile dysfunction (Glynn, Monane, Gurwitz, Choodnovskiy, & Avorn, 1999; Ramage-Morin, 2009). These medical conditions are treated and controlled with various types of medications. In fact, nearly 83% of older adults in Canada take prescription medications by age 65 years. Several of these medications can induce subtle side effects, including decreased visual perception. For instance, previous research indicated that side effects of commonly prescribed type-5 inhibitors (such as Viagra) may include declines in color perception (Azzouni & Abu Samra, 2011; Santaella & Fraunfelder, 2007).
