Retinopathy of Prematurity (ROP)
Retinopathy of Prematurity (ROP) is a potentially blinding eye disorder primarily affecting premature infants,
and is the leading cause of childhood visual impairment in the developed world. It occurs when the blood vessels in
the retina of the eye fail to develop and mature properly. This can lead to abnormal growth of the vessels and/or
scarring of the retina. If left untreated, this can lead to partial or total blindness in the affected eye.
ROP affecting premature infants
ROP is most commonly found in infants who are born before or at 32 weeks gestation, and is most likely to occur
in those born before or at 28 weeks gestation. The incidence of ROP increases with decreasing gestational age and
birth weight. It is also more likely to occur in multiple births, such as twins or triplets, and in infants with
low Apgar scores.
Treatments for ROP
The most common treatments for ROP include laser photocoagulation, cryotherapy, and scleral buckle. Laser
photocoagulation is the most common treatment and involves using a laser to seal off the abnormal blood vessels in
the retina. The laser is used to create a scar that will close off the abnormal vessels and prevent further growth.
Cryotherapy is another treatment option that involves freezing the abnormal vessels. This causes the vessels to
collapse and seal off, preventing further growth. Scleral buckle is the third most common treatment and involves
placing a band around the eyeball in order to press the retina back into its normal position. This helps to prevent
further stretching and tearing of the delicate retina.
Detecting Retinopathy of Prematurity (ROP)
Screening exams are the best way to detect ROP. The American Academy of Pediatrics and American Academy of
Ophthalmology recommend that all preterm infants be screened for ROP. The screening exam typically involves
dilating the eye to inspect the retina. If ROP is detected, the infant will likely be referred to a pediatric
ophthalmologist for further evaluation and treatment.
Causes for ROP
The exact cause of ROP is not known, but there are several risk factors that are believed to increase the
likelihood of its occurrence. These include premature birth, low birth weight, multiple births, multiple blood
transfusions, and oxygen therapy. Additionally, research has suggested that certain genetic factors may be
associated with ROP.
Retinopathy of Prematurity (ROP) Research
Much research has been conducted in the field of ROP and new treatments are continually being developed. Current
research is focused on the use of anti-VEGF (vascular endothelial growth factor) agents, which are drugs that block
the formation of new blood vessels. This can help to reduce the severity of the disease and improve the outcome for
the affected infants. Other research is focused on developing new screening methods that are more accurate and
effective in detecting the early stages of ROP.
In conclusion, Retinopathy of Prematurity (ROP) is a potentially blinding eye disorder primarily affecting
premature infants. It is caused by the failure of the retina to develop and mature properly, leading to abnormal
growth and/or scarring of the retina. Treatment typically involves laser photocoagulation, cryotherapy, and scleral
buckle, and screening exams are the best way to detect ROP. Current research is focused on the use of anti-VEGF
agents and developing new screening methods.
