In 1980, 120 cases with late-life migrainous accompaniments resembling transient ischemic attacks were presented. In the present paper, 85 further cases examined in the past five years are analyzed. The findings support the concept advanced previously. In general, the cases are divided into the same categories: visual--21 cases, visual and paresthesias--6, visual and speech disturbance--2, visu...

SUMMARY A 71 - year old woman with symptomatic Rathke's Cleft cyst is reported. She had Visual disturbance, diabetes insipidus and hypopituitarism. Imaging study with computed tomography revealed the presence of suprasellar mass. After the transsphenoidal surgery and treatment with DDA VP, her symptoms showed an improvement.

Cerebral visual impairment (CVI) is one of the leading causes of severe visual impairment in childhood. This article was written to highlight any new knowledge related to cerebral visual impairment in childhood.The international literature was searched to describe the type of visual, oculomotor and / or visuo-perceptual disturbances and to discuss the prognosis. CVI children show a wide range o...

Visual position and velocity cues improve human standing balance, reducing sway responses to external disturbances and sway variability. Previous work suggested that human balancing is based on sensory estimates of external disturbances and their compensation using feedback mechanisms (Disturbance Estimation and Compensation, DEC model). This study investigates the visual effects on sway respon...

This paper presents a visual servoing of 6 degreeof-freedom (DOF) manipulator based on intersample disturbance rejection with switching scheme. In the controller, multirate intersample disturbance rejection algorithm is utilized, which was proposed by authors for general digital control system with restricted sampling frequency. The proposed feedforward scheme with open-loop estimation and swit...

Over a 16-year period, 105 patients with pituitary adenoma accompanied by visual disturbance underwent transcranial intracapsular removal of the tumor followed by radiotherapy. Postoperative recovery of visual function in these patients was compared with the results obtained in other institutions after trans-sphenoidal surgery. The severity of preoperative visual impairment was correlated with ...
