RESUMO
In a retrospective postmortem study of 1,019 adult Jamaicans of African extraction, 350 (17.2 percent) of the 2,038 lungs were classified as normal. The weights of these lungs were compared with weights of lungs in abnormal categories and considerable overlap was found. It was concluded, however, that lungs that were normal to inspection and palpation but that weighed less than the mean could be included in studies requiring normal lungs. In 70 men and 81 women, both lungs were normal. Regression of the normal total lung weights were calculated with age, height, weight, and surface area. These factors accounted for only 11 percent of the variation in total lung weights in men and 14 percent in women. Analysis of male and female lung weights showed that for any given height and weight there was no significant difference between the sexes. No adequate data were available to compare races, but it was concluded that lung weight was more closely related to stature than to sex or, probably, to race.(Summary)

The importance of bilateral ambloyopia as a cause of a poor visual result following cataract extraction in West Indians is assessed. It is submitted that this disorder is more common than previously considered and an incidence of 5 to 7 per cent among 50 to 80-year-old Jamaicans undergoing cataract extraction is suggested. Factors influencing this figure are postulated. Certain clinical aspects of the condition are considered. (AU)
