The risk factors which are associated with ROP
are not fully understood, but prematurity, low birth weight and immature retina are the major risk factors.
Advances in neonatal intensive care management of extremely premature infants in the developed world and now also in developing countries, has led to an increased survival and an increase risk of long term morbidities like retinopathy of prematurity (ROP
).1 There are differing trends in the frequency and severity of ROP
ranging from 10.5% to as high as 58%.2,3 In preterm neonates the development of any ROP
is associated with both lower birth weight (BW) and lower gestational age (GA).4 There are various other risk factors for development of ROP
which include neonatal sepsis, respiratory distress syndrome, anemia resulting in multiple blood transfusions and apnea of prematurity.5 ROP
is considered as a preventable cause of blindness and therefore its screening is essential.
Under the court directives, RoP
cannot run its advertisement campaign any longer.
screening was started at 31 weeks postmenstrual age and no ROP
"Evaluating postnatal AA fraction after birth in addition to GA may be useful for ROP
prediction," the authors write.
IHC, which owns multiple hospitals in the mountain west region, had a total of 4-level III and 1-level IV NICU all in Utah where ROP
screening is routinely done during the study period.
The infants were divided into 3 groups: group A, without any ROP
; group B, with ROP
but not up to type 1 prethreshold or threshold ROP
; group C, with type 1 prethreshold or threshold ROP
was initially associated with premature birth and shortly after with oxygen treatment.
Middle-income countries that have infant mortality rates of ~50/100 000 population per annum are currently experiencing the so-called 'third epidemic' of ROP
as a result of improved survival rates coupled with poor oxygen control and poorly established screening policies.
Research on ROP
in Latin America and the Caribbean (LAC) began two decades ago and indicates the disease is a large problem in the region, where two-thirds of annual global cases of blindness caused by ROP
The first epidemic of ROP
occurred during 1940s and 1950s, mainly in developed countries due to unmonitored use of oxygen in premature babies.
The main risk factors related with the development of ROP
include low birth weight, low gestational age, and oxygen treatment (2).
