Chapter

Abstract

Many factors affect the selection of an appropriate penetration route for drug delivery to the posterior segment of the eye. Therefore, the molecular penetration routes need to be understood and considered thoroughly while designing a drug delivery system. In this chapter, four primary administration routes, these being (1) systemic, (2) topical, (3) periocular and suprachoroidal, and (4) intraocular, are discussed with unique advantages as well as their own challenges. To achieve a balance of the desired therapeutic outcomes without compromising safety and patient’s adherence to therapy, a number of formulations/actives have been investigated so far and are discussed in the various sections of this chapter.
