The other eye was gived cryotherapy according to the retinal response saught by the operationer.Results The damage to retinal is different when the cryotherapy temperature and time are unchanged that the damage area gets larger as the pen diameter gets longer.The cryotherapy time needed by 1.3 mm diameter cryotherapy pen is longer than other three diameter cryotherapy pens when the lightest retinal response could be saught by the operationer.Conclusion 1.5 mm diameter cryotherapy pen is the most suitable for the cryotherapy on retinopathy of prematurity.Read More
