Screening for retinopathy of prematurity (ROP) is currently undertaken
by experienced ophthalmologists using indirect ophthalmoscopy. However, the
proportion of screened infants requiring treatment is very low; only 6% of
infants who weigh less than 1251 g reached the threshold for treatment in
the Cryotherapy for Retinopathy of Prematurity Study,1
and fewer than 2% of infants in an audit of screening practices in the United
Kingdom required treatment.2 Such a low
treatment yield represents a massive funnel effect. This is probably not an
appropriate use of expensive ophthalmic expertise in the United States or
the United Kingdom and even more so in countries where such expertise is sparse.
The use of wide-field digital retinal imaging (RetCam 120; Massie Research
Laboratories, Inc, Dublin, Calif) allows us to explore the role of other professionals
in ROP screening. Roth et al3 have undertaken
a useful exercise by comparing images obtained using the RetCam 120 . . . [Full Text of this Article] Corresponding author: Alistair R. Fielder, FRCP, FRCS, FRCOphth,
