Answer to Question 1

ANS: D
Ptosis, or drooping of an eyelid, can be related to simple aging, with natural loss of elasticity and lid drooping, or it can result from a variety of other causes. The causes of ptosis are often categorized as congenital and acquired. Causes occurring after birth include trauma, conditions adding mass to the eyelid, and conditions that affect the nerves or muscles controlling the lid's position. In 75 of the cases, the first manifestation of myasthenia gravis is ptosis.

Answer to Question 2

ANS: C
Dacryocystitis is an infection of the lacrimal sac and is most common in infants, secondary to congenital stenosis of the lacrimal duct. If the duct is occluded, constant tearing may occur. The lacrimal sac may be edematous, red, and tender. Pressure over the sac produces purulent discharge.
