In Stargardt's disease, a gradual loss of vision may precede both the appearance of paracentral or peripheral retinal flecks as well as funduscopically obvious macular changes. This latency delayed a diagnosis of Stargardt's disease in a young girl who underwent neurologic testing for what eventually turned out to be a retinal problem. At one stage in evolution, when retinal flecks and only subtle changes in the maculae were present, a diagnosis of a pure form of fundus flavimaculatus was considered likely. When severe granularity and atrophy of the maculae later developed in the presence of the retinal flecks, a more appropriate diagnosis of Stargardt's disease was made. As the degenerative and atrophic changes in the maculae became more pronounced in early adulthood, the flavimacular retinal flecks had all but disappeared.
In two separate trials, 140 cases of Pregnancy Anaemia were investigated in the University Teaching Hospital, Lusaka. The distribution of anaemia was as follows: Iron deficiency 118 (84.2%); dual deficiency 15 (19.7%); haemolytic five (35%); and megaloblastic 2 (1.4%). Anaemia with megaloblastic change was more common in the second study.
Orbital wall infarction in a patient with sickle cell disease can present with periorbital swelling and subperiosteal collection and thus can mimic infection on CT. However, MR not only provides excellent morphologic information but, by characterizing the nature of the collection as containing blood, and by identifying bone marrow abnormality, can lead to the diagnosis of orbital wall infarction.
