Results of US randomized clinical trial of cryotherapy for ROP (CRYO-ROP
In the 1980s, the first clinical trial on ROP treatment (CRYO-ROP
) demonstrated that treatment was highly effective (9, 10).
Another reason was the fact that "threshold disease" which was included in CRYO-ROP
criteria was being used as the treatment indication in these studies.

Programs to prevent ROP-induced blindness were initiated in many countries beginning in the 1980s, when the CRYO-ROP study demonstrated the first positive results from treatment of this disease with cryotherapy (13).
Although the initial results of the Early Treatment for Retinopathy of Prematurity Cooperative Group (ET-ROP) study, published in December 2003, showed significantly better ROP outcomes than the CRYO-ROP study, after nine months of pre-threshold treatment (16), the authors of the current study, who began prospective data collection in 2002, preferred to use the classical indication for treatment (i.e., threshold ROP).
