Retinopathy of prematurity (ROP) is a disease that affects immature vasculature in the eyes of premature babies that potentially leads to blindness. Authors describe incidence,risk factors, pathophysiology and international classification of retinopathy of prematurity (ICROP).

In general it applies that the later the beginning of ROP, and thus the better developed the vascular system of the retina and the more peripheral the localisation of manifestations of ROP, the better the prognosis of the disease. Regression of ROP The active phase of ROP may leave regressive changes on the retina (termed cicatricose in the past). These involutionary changes on the retina are classified according to the International Commission for ROP: A. Vascular and retinal changes in the periphery of the retina. B. Vascular and retinal changes on the posterior pole of
