Zusammenfassung
Im Rahmen einer prospektiven Studie zur Analyse der natürlichen Verlaufsentwicklung der Retinopathia praematurorum konnte bei 22 Kindern der Manifestationszeitpunkt des Stadiums III nach vorhergehender Feststellung eines Stadiums I oder II und nachfolgend mindestens wöchentlichen Kontrollen bestimmt werden. Als Mittelwert der Stadium III-Manifestation wurden 66,5 Lebenstage bzw. 36,9 berechnete Schwangerschaftswochen ermittelt. Korrelations-, Regressions- und Faktoranalyse weisen den Risikofaktor Geburtsgewicht als relativ präzisen Prädikator für das Lebensalter der Stadium III-Manifestation aus. Durch Einführung der Risikofaktoren Schwangerschafts- und Beatmungsdauer konnte die Präzision des linearen Modells nicht wesentlich erhöht werden. Es wurde eine inverse lineare Regression zwischen Geburtsgewicht und Stadium III-Manifestation abgeleitet. Die Regressionssteilheit weist in erster Näherung eine Latenzabnahme der Stadium III-Manifestation um eine Woche bei einer Zunahme des Geburtsgewichtes von 200 Gramm aus.
Summary
In a prospective study on ROP development the age at stage III onset was determined in 22 preterms. They were enroled in the study after diagnosis of early stages (I or II). Follow-up examinations were scheduled at least weekly. The mean age of first ROP stage III observation was 66.5 days after birth or 36.9 weeks expressed as mean calculated gestational age. On the base of statistical analyses (correlation, regression, and factor) birth weight established as the most informative risk factor concerning the critical age of stage III onset. The introduction of further risk factors (gestational age and duration of O2-therapy) into the linear model was nearly without influence on the precision of the model. As a general guideline an inverse linear relation between birth weight and observed age of ROP stage III onset was established. According to this the age of stage III onset is delayed on average by one week with a decrease of 200 g in birth weight.
