To the Editor:—
Drs. Lee and Lam recently reported a case of unilateral blindness in a patient after prone lumbar spine surgery. 1 This unfortunate complication of surgery in the prone position has been reported in the surgical literature, 2–5 and less commonly in anesthesia journals. 6,7 
Drs. Roth and Barach write in the accompanying editorial 8 that there still are no answers as to the etiology of postoperative visual loss (PVL), although researchers are currently in the process of collecting much-needed prospective data to establish the cause(s) of PVL. In the meantime, we as anesthesiologists must be aware that PVL can occur despite our best efforts at prevention. Should we routinely inform patients of this risk? Our answer is yes, although there are some that would beg to differ. It is, however, an indisputable point that we should routinely ask patients questions about their vision in the recovery room and during the postoperative check. Although there is no definitive treatment for PVL, early detection with subsequent consultation with ophthalmologists, and rapid correction of possible causes of decreased oxygen delivery (e.g.  , anemia) may be the greatest hope for a patient who has suffered PVL.
