Retinopathy of Prematurity (ROP)

Melissa Andrews

BME 281 Sec 2


What is rop

What is ROP?

  • Affects the retinal blood vessels of premature babies

  • Retina forms early in development but blood supply does not

  • Affects 500 to 700 babies in U.S each year

  • The more premature the higher the risk

  • High Risk

    • <32 weeks

    • <3 pounds


Exams

Exams

  • High-risk infants should have retinal exams

  • Depending on gestational age first exam usually 4 - 9 weeks after birth

  • Babies 27 weeks or later have their exam at 4 weeks of age

  • Follow-up exams


Optical coherence tomography oct

Optical Coherence Tomography (OCT)

  • Noninvasive

  • Usually forms 2-D images

  • 3-D pictures can be formed


Spectral domain optical coherence tomography sd oct

Spectral Domain Optical Coherence Tomography (SD OCT)

  • Duke University Medical Center

  • Hand held

  • Narrow beam of broadband light sources

  • 3-D scanned image

  • 40 times faster than previous OCT

  • Faster = less time spent to diagnosis and faster recognition of ROP

  • Baby can remain in incubator during procedure


Treatments

Treatments

  • Treatment should start within 72 hours of the eye exam

  • “Plus disease” babies need immediate treatment

  • Cryotherapy (freezing)

  • Laser therapy

  • Surgery is needed if the retina detaches

  • Plus Disease
