One hundred eithy-six male (average 73.7 years) and four hundred and three female (average 75.7 years) cases, mostly residents of Yokufukai (Home for the aged) were autopsied and were investigated on the significance of clinical findings of eyeground in the prognosis of the aged. The study was made from December, 1962 to June, 1970.
Results and conclusions were as follows;
1) The narrowing and the irregularity in caliber of the retinal artery, bleeding and white spot in the retina, which were so called hypertensive findings of eyeground, were variable even in the aged 60 years or more, but the number of cases were few.
2) An increased in reflex of the retina, arteriovenous crossing, silver wire artery and white thread artery, which were so called sclerotic findings of eyeground, were not variable. These findings should be further investigated.
3) Sex difference in mortality rate was not observed. The mortality rate showed increased with age and increased with the increase in both the systolic or diastolic blood pressure.
4) The mortality rate with apoplexy and that with other cause of death were higher in those with higher grade of classification of eyeground findings. This tendency was most clearly observed in the sixth decades, however were not clear with progression of age. Therefore, the significance of the findings of eyeground for apoplexy were highly estimated in the sixth decades, and it's significance decreased as patients got older.
5) For knowing the prognosis of patients according to the findings of the eyeground, it is better to divide the group into three, namely negative, slightly positive and severly positive rather than by the 2 classification such as positive and negative.
6) By reason of the difficulty of it's judgement, there was a tendency to neglect the increase in reflex of the retinal artery, however this finding should be given importance with the narrowing and the irregularity in caliber of the retinal artery.
