Early pre-plus ROP may be linked to development of severe disease
Arch Ophthalmol. 2011;129(5):591-596.
Pre-plus retinopathy of prematurity that presents early may be strongly correlated with development of severe disease and a need for laser treatment, a prospective study demonstrated.
Two masked experts observed posterior retinal video recordings of 214 premature infants from 710 examinations conducted over a span of 5 years, classifying ROP as plus, pre-plus or neither.
Of 10 eyes with pre-plus disease at 33 to 34 weeks' postmenstrual age, 70% required laser surgery, while only 9% of 154 eyes with neither pre-plus nor plus disease required such treatment.
After adjusting for birth weight, gestational age, ROP location and disease severity, pre-plus disease at 33 to 34 weeks' postmenstrual age independently predicted the need for laser intervention. Mean time between diagnosis and treatment was 1.6 weeks.
