摘要:

The pathologic terms hamartoma, choristoma, nevus, and phakoma often are confused. We discuss them in relation to a patient with the linear nevus sebaceous syndrome who had a large limbal mass that grew unusually rapidly and was excised. Histopathologic examination showed that it was a complex choristoma composed of lacrimal gland, adipose tissue, and myxomatous tissue. The latter has not been described previously in this disorder. This neuro-oculocutaneous syndrome has been considered one of the phakomatoses.

摘要:

Free air within the cavernous sinus was discovered incidentally on a computed tomographic (CT) scan. We suggest that air bubbles were introduced inadvertently when contrast material was injected just prior to CT scanning. On a repeat CT scan 16 days later, the air had disappeared.

摘要:

We report a case of left-sided horizontal gaze palsy, ipsilateral adduction weakness, and left peripheral facial weakness, all of which indicate the lesion in the left median pontine tegmentum. The enhanced MRIs revealed a discrete left median pontine tegmental lesion, involving the abducens nucleus, MLF, and facial nerve knee. This lesion spared the area of the left PPRF. Among these structures, the area of the abducens nucleus seems to be responsible for the unilateral horizontal gaze palsy. We are not aware of any previous precise neuroradiological documentation of unilateral paralysis of conjugate gaze due to a lesion of the abducens nucleus by sagittal and horizontal MRIs.

摘要:

While participating in a controlled study of baclofen as protective therapy, 39 Huntington's disease (HD) patients underwent measurements of horizontal saccade latency and velocity, repeated longitudinally over a 2-year period. Significant worsening of saccade latency and of mean velocity was detected in untreated patients. Although individual variation was great, initial velocity impairment was found to be more prominent in younger patients. Factors are identified that may affect the rate of decline in supranuclear oculomotor function, including age and the severity of illness at the time of initial assessment. We propose that serial quantitative measurement of saccade performance is a useful clinical marker of the rate of disease progression against which the efficacy of treatments may be tested.

摘要:

In the neuro-ophthalmology clinic at St. Vincent's Hospital, Melbourne, 57 patients with blepharospasm and 50 patients with hemifacial spasm were treated with botulinum toxin. Schirmer tear tests were conducted on all the patients prior to each treatment and at 1 week following treatment where possible. The results were compared with a control group of 107 patients selected by age and sex. The blepharospasm patients were found to have a significantly lower tear secretion than that of the control group, using the Mann-Whitney test (median = 3.5 mm, compared with median-11.0 mm,p< .0001). This did not improve following treatment. The patients with hemifacial spasm did not have significantly different tear secretion from that of the control group (t= 1.0,p> .05). To investigate whether there was any relationship between the symptoms and the result of the Schirmer test, a survey was also conducted on the patients with blepharospasm and hemifacial spasm regarding symptoms, frequency, and type of drops/ointment used.
