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.

In the last 10 years bifocal concepts for intraocular lenses have been investigated with little success.

[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.

Xeroderma pigmentosum patients from Germany: clinical symptoms and DNA repair characteristics.

Dermatologic, ophthalmologic, and neurologic examinations were carried out on 33 patients with clinical symptoms of xeroderma pigmentosum (XP). Complementation groups were determined for 23 patients. Types of tumors and complementation group were found to be related in the following way: In the XP variant groups basaliomas were the most frequently occurring malignant tumors, whereas in the D group pigmentary tumors, such as melanotic precanceroses and melanomas prevailed; in the A and the C group, spinaliomas seem to be the most frequent malignomas.
