[Eosinophilic, central necrotizing granuloma of the conjunctiva (Splendore-Hoeppli phenomenon). Clinical-histopathological study].

Six patients with the clinical and histological findings of a so-called Splendore-Hoeppli phenomenon are described. The clinical picture is one of yellow, painless episcleral nodules with associated vascular injection; they are unilateral or bilateral, and isolated or multiple. Histologically, the granulomas are composed of a central eosinophilic material surrounded by epitheloid cells, giant cells and numerous eosinophils. The phenomenon is interpreted as an antigen-antibody precipitation as originally described in relation to parasites and fungi. Blood eosinophilia was seen in two patients. No parasitic or fungal agents were found in serial sections in this series and would not be detected on general examination. The diagnosis is established by histological examination. Topical corticosteroid therapy was ineffective. Excisional biopsy of the granuloma is the therapy of choice.

Morphological studies on the regeneration of rabbit corneal endothelium under the influence of corticosteroids.

In adult albino rabbits, the influence of corticosteroids on the regeneration of the corneal endothelium after cryocoagulation was studied using light-, scanning- and transmission electron microscopy. The follow-up period varied from 10 h to 10 days. In the regenerating endothelium, both mitotic and amitotic cells division were seen. In the dexamethasone-treated eyes, the regeneration process seemed to be stimulated rather than inhibited. In five of six eyes, areas of hyperproliferation were found, consisting of numerous elongated cells that formed several cell layers. Most of these cells revealed an extensively developed endoplasmic reticulum and Golgi apparatus as well as numerous mitochondria. There were signs of secretory activity. The mechanism for the development of these multilayered hyperproliferation zones is unknown.

[Diffuse endothelialization of a cyclodialysis cleft: a light and electron microscopic study].

Twenty years after surgical cyclodialysis it became necessary to remove the right eye of a 58-year-old patient with chronic unspecific anterior uveitis who had developed a painful secondary glaucoma. Light and electron microscopic investigation revealed that a complete, diffuse endothelialization with a Descemet-like basement membrane had lined the anterior chamber and the cyclodialysis cleft. The endothelial cell structure was fenestrated and the basement membrane was a "multi-layered Descemet-like membrane". Clinical and histological differential diagnoses of such membrane formations are discussed. Endothelialization of the cyclodialysis cleft can be the cause of an unsuccessful operation.
