Guidelines for screening for retinopathy of prematurity (ROP) and indi
cations for treatment are well established, but implementation of scre
ening and delivery of treatment may be problematical. We have performe
d a national survey of 118 specialised units dealing with at risk neon
ates to audit current practice in Britain and to identify practical pr
oblems with screening and with treatment. A screening policy for neona
tes at risk is in practice at 97% of units, performed by consultant op
hthalmologists in 86% of centres. Units referred to specialised treatm
ent centres in 23% of cases. An average of 54 infants at risk of ROP w
ere screened by each of 118 units throughout Britain in 1993, and appr
oximately 3% of these infants underwent treatment for ROP. Cryotherapy
was used for treatment in 85% of units, laser photocoagulation in 51%
and both treatment modalities were used in 36% of units. Less than 1/
4 of the neontologists polled were of the opinion that they should be
trained to screen for ROP themselves. These results show that the scre
ening guidelines have been successfully implemented in Britain, but de
monstrate a wide variation in practice. Problems with screening and tr
eatment are discussed.
