Reversible Bitemporal Hemihypokinetic Pupil Without Hemianopia: A New Chiasmal Sign.

Chiasmal syndromes present mostly with visual problems, such as changes in visual fields, decreased visual acuity, or dyschromatopsia (and classically without pupillary reflex defects). The prototypical bitemporal hemianopia upon visual field testing can easily suggest chiasmal compression due to sellar/suprasellar involvement. However, because of the complexity of the decussation of fibres at the optic chiasm and the presence of anatomical variants, unpredictable visual fields defects can be detected in chiasmal diseases.

Peripheral clock system circadian abnormalities in Cushing's disease.

In Cushing's syndrome, the cortisol rhythm is impaired and can be associated with the disruption in the rhythmic expression of clock genes. In this study, we evaluated the expression of genes in peripheral blood leukocytes of healthy individuals (n = 13) and Cushing's disease (CD) patients (n = 12). Participants underwent salivary cortisol measurement at 0900 h and 2300 h.

[Factors related to glaucoma treatment compliance: patients' opinions from a University Hospital].

Purpose: Considering that noncompliance to glaucoma treatment is one of the risk factors associated with disease s progression, the purpose of the present study was to evaluate: 1) knowledge and feelings about the disease; 2) self-reported noncompliance to treatment and related factors; and 3) influence of disease in lifestyle.

Methods: Interviews, with application of a semi-structured questionnaire, of 50 patients with primary open-angle glaucoma. The analysis was performed using Lefèvre's technique (Collective Subject Speech--CSS, qualitative/quantitative research).
