Retinopathy of Prematurely (ROP) is commonly seen in premature born infants. It chiefly causes the disease of the retina.
Causes of Retinopahy of Prematurity:
It mainly consists of abnormal retinal vessels that grow mostly in an area where normal vessels have grown in the retina. It has been known that the area of the retina affected by this disease is divided into three main zones. Moreover ROP is also divided into stages 1 to 5. Stages 1 and 2 usually do not require treatment. Whereas, babies who develop stage 3 ROP, generally requires treatment.
Symptoms of ROP
As the retinal area affected by ROP is divided into three main zones. Zone 1 is centrally located and ROP develops in this zone if the retina in this are is most underdeveloped. Disease as compared to the disease seen in Zone 2 or 3.
It has been observed that the timing is an important factor that makes the treatment successful in Retinopathy of Pre-maturity. It is because the disease can advance quickly and delayed treatment often reduces the chances of success. The rapidly progressing disease and it is usually associated with very extensive or abnormal blood vessels.
Abnormal dilatation of retinal veins may lead to a disease known as Plus disease. In stage 1 ROP the retinal blood vessels fail to reach the retinal periphery and multiply abnormally. After a normal birth, the retinal blood vessels fill the anterior periphery zone 1 is the most posterior retina, which contains the optic nerve the macula.
