The dispassionate numbers in the preliminary report of the Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP)1 fail to convey the excitement I feel as a physician who now, for the first time, has a tested intervention to offer the infant with serious retinopathy of prematurity. Infants with retinopathy of prematurity at the study's threshold of severity have a 43% incidence of an unfavorable outcome in that eye, eg, retinal detachment or a fold across the macula. Either of these outcomes means severely reduced vision for life. Cryotherapy reduces the chances of an unfavorable outcome to 22%. The preliminary report, however, has left many questions unanswered.
