Retinal haemorrhages were studied in a consecutive series of 99 babies delivered by forceps, 94 delivered by vacuum extractor and 207 delivered spontaneously. The incidence of haemorrhages for spontaneously delivered was 27.5%, for those delivered by forceps 38%, and for those delivered by vacuum extractor 64%. The incidence of haemorrhages in the group of vacuum extractions was significantly higher than among either the group of forceps extractions or the spontaneous deliveries. In addition, more severe haemorrhages were found in the group of vacuum extractions. Influence on the incidence of haemorrhages by factors other than type of delivery could not be verified statistically.
