Answer to Question 1

ANS: A
The most common cause of eye redness is conjunctivitis (see Plate 38), which involves an inflammation of one or more areas of the conjunctiva. It is important to discriminate between allergic, viral, bacterial, and other causes of conjunctivitis in order to provide definitive treatment. Infectious conjunctivitis is usually caused by viral organisms, although bacterial infections are also common and can be secondary to viral infections. Allergies are the most frequent cause of noninfectious conjunctivitis. Other causes include chemical reactions.

Answer to Question 2

ANS: D
Most commonly, macular degeneration is associated with aging and results either from atrophy of the macula or exudation and hemorrhage of the vessels in the macular region.
