The Retinopathy of Prematurity

The retinopathy of prematurity.

When the condition of retrolental fibroplasia was first described by Terry (1942) in the United States of America it was then only recognized in the advanced state of a cicatricial mass or membrane behind the lens. It is now appreciated, however, that the earliest pathological changes occur in the nerve fibre layer of the retina, which first of all becomes thickened as a result of oedema, trans...

Retinopathy of Prematurity

The incidence of ROP varies with birth weight but it has been reported to be approximately 50-70% in infants whose weight is less than 1250g at birth. The more premature the infant, the more likely ROP is to develop [1]. Furthermore, an observational study from United Kingdom found that the birth weight of infants from highly developed countries was 737-763g compared with 903-1527g in less-deve...

Classifying retinopathy of prematurity

It is important to classify retinopathy of prematurity (ROP) in each eye, at each screening session. Doing so makes it possible to screen babies consistently and to make decisions about whether further screening is required and when, or whether laser treatment or surgical management is needed. The International Committee for the Classification of ROP1 has classified it using the following crite...

Retinopathy of prematurity.

With improved survival of very low birth infants in India, Retinopathy of Prematurity (ROP) is emerging as a significant problem. The most important risk factor in the pathogenesis of ROP is prematurity. Other factors like, problems with oxygenation frequent blood transfusions, sepsis and apnea have also been implicated in the causation of ROP. Essentially asymptomatic in the initial stages, a ...
