Alexia without agraphia in a right-handed patient with a left Field defect and diffuse cerebral atrophyA right handed patient with alexia without agraphia, a left visual field deficit, intact color naming and diffuse cerebral atrophy on CT is presented. Neuro-psychological testing supported a ...
The correct diagnosis is homonymous hemianopia. Infants with a homonymous hemianopia can present with an anomalous head position where they turn their face ipsilateral to the visual field defect. It is hypothesized that children adopt this head position because it expands the view of the deficien...
He complained of progressive deterioration of vision in his left eye, floaters and a nasal visual field defect. Fifteen years previously, he had had a malignant melanoma removed from his right arm, followed after 6 years by axillary lymph node clearance for local recurrence. After 6 years still...
What visual field defect would result from a lesion of the optic nerve, optic chiasm, and optic tract?In what part of the eye are the cones located?An experiment was done in which optic chiasm was severed and you were forced to cover your right eye. Which of the foll...
She had small, tilted optic discs, and repeated automated Humphrey visual field testing confirmed a left nasal step visual field defect. Bilateral Nd:YAG peripheral iridotomies were performed, which resulted in deepening of the anterior chambers, however, the left IOP continued to remain elevated ...
A patient can't see anything in the left visual field when it's mapped with both eyes open. Which is the most likely site of damage to the central visual pathways? A. left optic tract B. optic chiasm C. right optic nerve D. right opt...
Hence, a defect in this pathway would not cause the deterioration of orthographic processing in reading. In our results, although the FA values of the SLF were significantly correlated with the behavioral indices, the lesion volume of the tract failed to reach a significant level. 4.3. ...
using Ishihara plates was 12/12 in the right eye and 0/12 in the left eye. Pupil examination revealed anisocoria with a briskly reactive 4-mm pupil in the right eye, and an unreactive 6-mm pupil with a reverse relative afferent pupillary defect in the left eye. Both eyelids were ...
The ski is a notable rolling defect whose leading end bends upward or downward [5]. Nilsson conducted experiments to understand various parameters that influenced the ski-end behavior in plate rolling [6]. Philipp et al. investigated front-end bending in plate rolling due to the mismatch in ...
The hippocampal CA3 contributes to spatial working memory (SWM), but which stage of SWM the CA3 neurons act on and whether the lateralization of CA3 function occurs in SWM is also unknown. Here, we reveal increased neural activity in both sample and choi
