In a prospective, randomized clinical trial comparing transscleral
cryotherapy with laser photocoagulation in the treatment of "threshold"
stage 3+ retinopathy of prematurity, 32 infants were treated with diode
laser photocoagulation in one eye. Twenty-eight infants have been followed
up for at least 3 months, and seven have been followed up for at least 1
year. Twenty-five of 28 eyes treated with diode laser photocoagulation and
followed up for at least 3 months have undergone regression. Of 24 fellow
eyes treated with cryotherapy and followed up for at least 3 months, 20
have undergone regression. All seven eyes treated with diode laser
photocoagulation and followed up for at least 1 year have undergone
regression. Of seven fellow eyes treated with cryotherapy and followed up
for at least 1 year, all have undergone regression. Our results suggest
that diode laser photocoagulation is as effective as cryotherapy in the
treatment of retinopathy of prematurity.
