The article “Ocular Emergencies” (September 15, 2007, page 829) contained an error in Figure 2B on page 833. The figure should have had two arrows pointing to areas of retinal edema. Instead, only one arrow appeared and pointed to the normal portion of the retina. The corrected version of the figure appears below and has been corrected online.
Figure 2.
(A) Normal right fundus and (B) a left fundus with retinal edema secondary to central retinal artery occlusion. The central macula is still being perfused because of the presence of a cilioretinal artery, which is found in 15 percent of the U.S. population.
