About Retinopathy of Prematurity
World health organization (WHO) has launched ‘VISION
2020’ program for elimination of preventable blindness. Control of childhood blindness
is one of the priorities identified as a part of this program. Evidence suggests that
one out of every 1000 children is blind in India. Few important causes responsible for
blindness in India are corneal scarring mainly due to vitamin A deficiency (26.0%,
though reduced now), globe abnormalities (25.0%), cataract (12%) and retinal disorders
(21.0%).
Retinopathy of prematurity (ROP) is a vascular proliferative retinopathy seen in low
birth weight premature infants. It is one of the leading causes of avoidable severe
visual disability and childhood blindness worldwide. With increasing survival of infants
due to the advancements in paediatric neonatology care, there is increase in the
incidence of ROP in India and in low and middle income countries10-12. It is slowly
emerging as an epidemic.
ROP has wide spectrum of presentation, ranging from mild transient changes, which
regresses spontaneously, to more chronic and severe form like retinal detachment and
scarring which are irreversible and can lead to total blindness.
Timely screening and early treatment, when needed, can prevent the progression of ROP to
advanced stage in majority of these neonates. Management of ROP has evolved over last 2
-3 decades. Though surgery can be performed in the advanced stages of ROP, generally the
overall visual prognosis is poor. Hence it is important to implement an effective
screening program with appropriate referral and management protocol at the primary
level. All ophthalmologists, neonatologists, obstetricians and other healthcare
professionals must be made aware of ROP and its sight threatening potential.
