Assessment of the posterior segment of the cat eye by optical coherence tomography (OCT).

Objectives: To assess the feasibility of optical coherence tomography (OCT) for examining the cat ocular fundus, to provide normative data on retinal thickness in different fundus regions, and to demonstrate selected surgically induced vitreoretinal pathologies in the cat.

Animal Studied: Forty-five eyes of 28 healthy domestic cats and two eyes of domestic cats that had undergone subretinal implantation surgery for a visual prosthesis were examined.

Procedures: An optical coherence tomograph (Zeiss-Humphrey) was used to examine the anesthetized animals.

[Structured treatment of diabetes in the country].

The aim of the DIALA project was to demonstrate the feasibility of structured treatment and teaching programs for type 2 diabetic patients in order to improve the overall quality of care. The investigation was carried out in Upper Austria. The results and findings of structured treatment were evaluated as well as the associated costs of current diabetes management.

In vivo assessment of subretinally implanted microphotodiode arrays in cats by optical coherence tomography and fluorescein angiography.

Background: Following multiple promising investigations into restoration of vision in degenerative retinal disease by implantation of a sub- or epiretinal prosthesis, the step to clinical use in humans is impending. In this study we intended to establish optical coherence tomography (OCT) and fluorescein angiography (FA) first in research animals for noninvasive assessment of the condition of the posterior pole of eyes after intraocular implant surgery.

Methods: Three adult cats that had undergone subretinal implant surgery were evaluated by OCT and FA between 1 and 470 days postoperatively.

[Functional and structural follow-up findings in complicated migraine].

The rare case of a status of complicated migraine with more than two weeks duration and severe neurological deficits is reported. The clinical symptoms were global aphasia, mild fluctuating hemiparesis on the right side and headache without localization on one side. The presence of a characteristic constellation of morphological and functional findings on investigation (EEG, SPECT, TCD) helped to clarify the diagnosis.
