Q

Acquired Conditions of the Newborn:

Retinopathy of prematurity (ROP):

ROP- is abnormal vascular growth of the blood vessels of the retina in infants born prematurely. What does it cause?

Treatment is only required for severe disease and includes laser photocoagulation and/or anti-vascular endothelial growth factor monoclonal antibodies.

82
Q

Acquired Conditions of the Newborn:

Retinopathy of prematurity (ROP):

What is nursing management?

A

Administer oxygen therapy cautiously- ensure lowest concentration and shortest duration

Assist with scheduling opthalmic exam

Protect newborn’s eyes from light after exam

Provide parents support by giving them information and providing detail about the conditions and follow-up examinations
