“…Krauer-Mayer ( 1965) found 50% after vacuum, 20.5% after spontaneous delivery and 19% after forceps. The corresponding figures reported by Neuweiler & Onwudiwe (1967) were 72. 4%, 34.8% and 42.896, while Ehlers et al (1974) found 64%, 27.5% and 38% respectively.…”

The present study shows the frequency and severity of retinal haemorrhages in 200 newborn, of which 100 were delivered spontaneously, 51 delivered by vacuum extractor and 49 by forceps. The incidence of retinal haemorrhages was highest in the vacuum group (50%), lowest in the forceps group (16%), while the spontaneously delivered children showed an incidence of 41%. The incidence of severe retinal haemorrhages was about five times higher in the vacuum group than in both forceps and control groups. The authors propose a quantitative grading of the haemorrhages. The purpose has been to obtain a better way of relating the haemorrhages to mode of delivery and probably also to relate retinal haemorrhages to possible brain damage.

“…Large numbers of haemorrhages and large splash-like haemorrhages took longer to resolve than small numbers of small haemorrhages, and peripheral haemorrhages usually resolved first. In babies, the type and position of retinal haemorrhages have a marked effect on their rate of resolution (Neuweiler and Onwudiwe 1967, Baum and Bulpitt 1970, Sezen 1971). In these foals the onset of resorption first became visible as the margins of the haemorrhage became less distinct.…”

Survey of retinal haemorrhages in neonatal thoroughbred foals

Twenty-seven of 167 neonatal thoroughbred foals (16 per cent) were found to have retinal haemorrhages after a careful examination of the entire fundus. Experience in differentiating haemorrhages from other lesions, and the selection of foals from normal populations, were considered to have an important effect on their apparent incidence. Bilateral haemorrhages were more common and there was a significantly higher incidence in female foals. The numbers of haemorrhages ranged between one and 20; 36 per cent of eyes with retinal haemorrhages had the small punctate type and 56 per cent had the splash-like form. There was no change from one type of haemorrhage to another, and the patterns of resolution were similar. The haemorrhages were in the tapetal fundus, except two that were recorded in the optic disc, and they resolved within 10 days. No short- or long-term ocular or neurological effects of the retinal haemorrhages were detected, and they were not related to the incidence of abnormal foal behaviour.

“…It has been frequently stated that the mode of delivery has an influence on the incidence of retinal haemorrhages, which is low after Caesarean section and high after vacuum extraction (Sanchez Ibafiez et al, 1963;Neuweiler and Onwudiwe, 1967;Krebs and Jager, 1966). However, in assessing the significance of retinal haemorrhage after abnormal delivery one must bear in mind the high incidence after entirely normal parturition, and the importance of specifying the exact time after birth when the retinae were examined.…”

“…Eleven years later Jaeger first described retinal haemorrhages in newborn infants (Jaeger,1861). Many studies have since been made concerning the incidence, morphology, aetiology, and significance of these haemorrhages (Richman, 1936;McKeown, 1941;Giles, 1960;Sanchez Ibaiiez, Belmonte Gonzalez, and Navarro Martinez, 1963;Jain and Gupta, 1965;Schenker and Gombos, 1966;Krauer-Mayer, 1966;Neuweiler and Onwudiwe, 1967). An excellent review is given by Critchley (1968).…”

. (1970). Archives of Disease in Childhood, 45, 344. Retinal and conjunctival haemorrhage in the newborn. Two hundred and thirty newborn infants were examined for retinal and conjunctival haemorrhages. Retinal photographs were taken in selected cases to record the morphological varieties and the different rates of disappearance of the retinal haemorrhages.The incidence of retinal and conjunctival haemorrhages was studied in relation to a number of possible aetiological factors. In the case of retinal haemorrhages we did not identify the critical factor or factors that determine their occurrence. Neither cephalic venous congestion, nor a coagulation defect, nor birth asphyxia was associated with retinal haemorrhages. It is likely that they are of multifactorial origin, and it is suggested that blood viscosity may be an important contributory factor.In contrast, conjunctival haemorrhages occurred in association with multiparity, rapid second stage of labour, Negro race, high Apgar score, and relatively high birthweight, head circumference, and gestational age. In addition the occurrence of conjunctival haemorrhage as part of the picture of 'traumatic cyanosis' suggests that these lesions do result from changes in cephalic venous pressure.The first practical ophthalmoscope was introduced by Helmholtz in 1850. Eleven years later Jaeger first described retinal haemorrhages in newborn infants (Jaeger,1861). Many studies have since been made concerning the incidence, morphology, aetiology, and significance of these haemorrhages
