Abstract

Although the reports of the use of crotherapy in the control of the proliferative phase of retinopathy of prematurity varied in their conclusions regarding the merits and limitations of this therapy, cryotherapy has been consedered to be an effective treatment for retinopathy stage 3. The accepted method of therapy includes ablation of the whole avascular retina from the ridge to the ora serrata. This is achieved by 2 to 3 rows of cryoapplications with use of cryotherapy probe for ROP. Nissenkorn et al presented their new method of cryotherapy in which only one row of cryoapplications was applied in the avascular retina anterior to the fibrovascular ridge. So, we performed cryotherapy using Nessenkorn's new method on 7 babies and the anatomical results are reviewed. Complete regression of active retinopathy was achieved in all of the eyes treated.
