ABSTRACT
A case of cystoid macular oedema lying over a malignant melanoma of the choroid is reported. A direct correlation between the histopathological findings and the fluorescencangiographic picture is shown. The fluorescencangiography was taken 14 days before enucleation and showed the typical structure of a cystoid maculaoedema. The pathogenesis of the accumulation of the fluid within the layers of the Henle' fibres and the inner nuclear layer are discussed.

The corneas of 100 patients on dialysis for renal failure were observed. In 52 patients follow up studies were possible. 55 patients demonstrated limbal changes. On slit lamp biomicroscopy these changes showed to be similar to the white limbus girdle described by Vogt. Small limbal biopsies from five patients on dialysis were studies histopathologically and compared to biopsies from three patients with normal renal function. Only patients on dialysis showed senile elastosis and three of them epithelial and subepithelial hyaline deposits. Calcium deposition was the same in both groups.

Between 1966 and 1974, 1260 lidtumours were sent to the histological laboratory of the University Eye Hospital Hamburg. The clinical diagnosis "chalazion" in 138 cases could not be verified histologically in 33 cases. Other benign lesions were diagnosed 23 times and malignant lesions in 10 cases (4 times a Meibom's sebaceous cell carcinoma). The symptoms of all 7 Meibom's sebaceous cell carcinomatas diagnosed histologically during this time (the most common metastasizing lid-tumor in this series) were also analysed as they present the gravest diagnostic error for chalazia. Histologic examination of excised "chalazion"-material must be considered mandatory in all patients with a typical symptomatology, recurrence at the same site, high age, unilateral therapy-resistant keratoconjunctivities and involved regional lymphnodes.
