Which route is primarily used to treat eye disorders with local effects?

• A. Ocular route
• B. Nasal route
• C. Transdermal route
• D. Oral route

Answer: (A)

Delivering medicine directly to the eye provides the highest drug concentration at the site of action in ocular tissues while minimizing systemic exposure. This direct, local administration—through eye drops, ointments, and other ocular formulations—targets surface and anterior segment disorders effectively. The eye’s barriers limit systemic distribution, so using the ocular route is ideal for local therapy. Other routes deliver drugs systemically or to areas away from the eye (nasal, transdermal, or oral), and do not provide the same focused local action on ocular tissues.
