Final answer:
Ocular drugs are often used to target the sclera and ciliary body in the eye and can be administered as eye drops or injections.
Step-by-step explanation:
The drugs that often reach target tissues in the eye, such as the sclera and ciliary body, via blood vessel uptake are called ocular drugs.
These drugs are usually administered topically as eye drops or through injection directly into the blood vessels supplying the eye.
An example of an ocular drug is phenylephrine, which can be used to increase blood pressure in situations where cardiac function is compromised or for dilating the pupil during an eye examination.
