What is another name for ROP ? |
AKA - Retrolental Fibroplasia |
|
|
What is ROP ? |
- Disease that affects growth of blood vessel in the retina
- A common cause of childhood visual impairment / blindness |
|
|
What does ROP caused by in theorized in 1950 ? |
Caused by O2 |
|
|
What is the etiology of ROP ? |
- Low birth weight or premature babies who received supplemental oxygen - Increased PaO2 , not necessarily increased FiO2 -Generally there is no known safe PaO2 or time period of exposure - AAP recommends PaO2 of less than 80 torr to minimize the risk of ROP |
|
|
What are estimated PaO2 with the age of full term and premature ? |
- Full term : 80 torr after 72 hours
- Premature : 60 - 80 torr after 72 hours |
|
|
True or False : ROP is rare in full term babies ? |
True |
|
|
What is the pathophysiology of ROP ? |
Excessive blood oxygen levels lead to retinal vasoconstriction |
|
|
What does excessive blood oxygen levels that caused retinal vasoconstriction leads to ? |
- Necrosis of the blood vessel - New vessels will form and increases in number - Hemorrhage of these vessels will leads to scarring behind the retina - Scarring can lead to retinal detachment and blindness |
|
|
What are the risks factors of ROP ? |
- Prematurity less than 32 weeks - Low birth weight less than 1500 gm - High level of O2 - Mechanical ventilation - Apnea - High CO2 level - Blood transfusion |
|
|
What is the symptoms / Diagnosis of ROP ? |
- Difficult to assess with newborns - Policy by AAP - Eye exams |
|
|
What are preventions of ROP in Newborns ? |
- Close monitoring of ABG - Use of SpO2 monitoring - Use of TCM monitoring - Try to keep the PaO2 within earlier stated guidelines ( Esp. during first 72 hrs) - Avoid hyperoxia ( greater than 92% SpO2) - Using non- oxygen methods of improving SpO2 |
|
|
What is the treatment of ROP ? |
- Prevention is the best treatment - Stages 1- 3 usually reslve - More severe - surgical options |
|
|
What is the prognosis of ROP ? |
- Depend solely on severity - Some, no effects at all - Some blindness - Corrective lenses |
