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.
"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.
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 occur (7).
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).
