Bifocal ultra thin intraocular lens--optical properties and clinical results.

The therapy of the cataract with the implantation of intraocular lenses is a great success story over the last 20 years. However cataract patients cannot accommodate anymore and need additional glasses for the far and near view. In the last 10 years bifocal concepts for intraocular lenses have been investigated with little success. Our new bifocal diffractive bifocal lens showed in clinical trials with 150 Patients an excellent visual performance. Less than 10% of the patients still use additional glasses. Due to the diffractive principle the lens can be manufactured very thin. Therefore the lens can be easily implanted through very small incisions. The lens shows the potential for the replacement of multifocal glasses.

[Clinical aspects and histopathology of the Cogan-Reese syndrome].

The present paper reports on a 55 year-old patient who had been suffering from progressive essential iris atrophy in her left eye since the age of 24. Ten years later she developed partial secondary angel-closure glaucoma that failed to respond to repeated surgical treatment. Twenty years after onset of the disease, pigmented nodules appeared on the left iris, leading to the diagnosis of Cogan-Reese syndrome. Finally, 30 years after onset of the disease, the blind and painful eye was enucleated. The typical histologic findings in Cogan-Reese syndrome were confirmed by light and electron microscopy.

["Primary" reticulum-cellsarcoma of the retina. I. Clinico-pathologic study of 5 patients (author's transl)].

Between 1964 and 1974 a primary reticulum-cellsarcoma of the retina was diagnosed histologically in 5 patients (between 44 and 71 years), in one already clinically. The initial diagnosis had been "uveitis" (2), "panuveitis" (1), "iridocyclitis with central retinal artery occlusion" (1), and "chorioretinitis" (1). The usual antiinflammatory therapy was without effect in every instance. All patients showed neurological symptoms with cerebral manifestations. Twice the cerebral biopsies had been misinterpreted initially as "atypical glioblastoma multiforme", once as Neuro-Behçet. The disease progressed over a course of 2--10 years from the initial ophthalmic symptoms to death. A review of the literature is given and the differential-diagnosis to necrotizing forms of retinitis, dissiminated chorioiditis neoplastic processes of retina and uvea and degenerative diseases are discussed. The primary reticulum-cellsarcoma of the retina must be considered in the differential-diagnosis of uveitis or panuveitis if 1. there is progression in spite of the usual antiinflammatory therapy, 2. the initial infiltrations are seen in the deep layers of the sensory retina.
