How is ROP test done?

How is ROP test done?

This test is done inside the neonatal unit or hospital, during a visit by the retina specialist or paediatric ophthalmologist. The pupils of the eye are dilated using drops and the retina is examined with an indirect ophthalmoscope for signs of ROP.

What is ROP eye surgery?

ROP surgery involves scarring areas on the peripheral retina to stop the abnormal growth and eliminate pulling on the retina. Because surgery focuses on the peripheral retina, some amount of peripheral vision may be lost.

Why does oxygen cause ROP?

ROP is believed to occur because of an increase in angiogenic factors caused after a preterm infant is no longer in supplemental oxygen and the avascular retina becomes hypoxic. Therefore, the extent of avascularized retina may be important.

What are the symptoms of retinopathy of prematurity?

Signs & symptoms

• White pupils, called leukocoria.
• Abnormal eye movements, called nystagmus.
• Crossed eyes, called strabismus.
• Severe nearsightedness, called myopia.

When should ROP test be done?

Initial screening should be performed at 31 weeks’ postmenstrual age in infants with gestational ages of 26 6/7 weeks or less at birth, and at four weeks’ chronological age in infants with gestational ages of 27 weeks or more at birth by an ophthalmologist skilled in the detection of ROP.

How can ROP be prevented?

Preventing ROP before delivery A course of steroids, given to mothers likely to give birth prematurely, improves survival and reduces the complications of prematurity, including ROP. Antenatal steroids should be routine for mothers likely to give birth to a baby of less than 35 weeks’ gestation.

Is retinopathy of prematurity curable?

In most cases, ROP resolves without treatment, causing no damage. Advanced ROP , however, can cause permanent vision problems or blindness.

Why ROP screening is important?

A small proportion of premature infants develop potentially severe retinopathy which can be detected through retinal screening. If untreated, severe disease can result in serious vision impairment and consequently all babies at risk of sight-threatening retinopathy of prematurity should be screened.

What is the criteria for ROP screening?

All babies less than 32 weeks gestational age (up to 31 weeks and 6 days) or less than 1501g birthweight should be screened for ROP. One criterion to be met for inclusion. All babies less than 31 weeks gestational age (up to 30 weeks and 6 days) or less than 1251g birthweight must be screened for ROP.
