To the Editor.
—I read with interest the article by the Committee for the Classification of Retinopathy of Prematurity,1 and I have two remarks on the subject. First, I think that fluorescein angiography of the suspected fundus would give a better and an exact evaluation of the vascular pathology. Second, I expected to find in the conclusions of the article some indications as to the interval between the examinations related to the specific stage and the length of time the infant must be under the observation of an eye doctor.
