[Ophthalmological screening for retinopathy of prematurity].

Retinopathy of prematurity (ROP) is one of the three leading causes of legal blindness in childhood in developed countries. Adequate screening is one of the most important steps towards successful treatment. During the last decades, international and national guidelines for ROP screening have been continually updated. These guidelines correspond to progress in neonatal care and to a better understanding of the relationship between different neonatal parameters and the risk of developing ROP. The present article surveys ROP classification, the current national and international guidelines and new aspects of ROP screening.
