A prospective study of the eyes of 75 diabetic women during the course of 100 pregnancies is presented as a contribution to the, as yet, still unresolved question concerning the influence of pregnancy on diabetic retinopathy. Fifty patients in the material had a retinopathy prior to pregnancy, proliferations were present in 2 of them. During the course of the pregnancy, proliferative changes developed in 4 patients, and a background retinopathy developed in a further 4 patients. Special interest is placed on the transitory changes in the retinopathy that occurs in a number of these patients. In the present material this has occurred in 23 patients, all of whom had a retinopathy. This is especially apparent in the form of soft exudates, haemorrhages and retinal oedema. In marked cases a characteristic feature was an obvious capillary change. This transitory capillaropathy is considered as being the cause of this temporary increase in the severity of the retinopathy. The changes regressed in all of the 23 patients. The results confirm that pregnancy can hardly be considered to influence the further course of a background retinopathy. Even though the question as to whether pregnancy can influence the course of a proliferative retinopathy still remains open, evaluation of both the present and previous materials suggest that pregnancy by and large does not aggravate the 'average' progression of a proliferative diabetic retinopathy.
In a hospital material from North Jutland consisting of 192 cases of open-angle glaucoma, pseudoexfoliations were found in 50 cases, i.e. 26%. So far glaucoma capsulare has been regarded as rare in Denmark, but the incidence found here corresponds well to the one now considered to be valid for the glaucoma population in Norway, where this type of glaucoma has been found particularly frequently. The material supports the by now more widespread objections to the existence of actual geographical differences concerning the frequency of glaucoma capsulare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
