Introduction:
This study aimed to describe retinal microvascular changes in patients diagnosed to
have stroke and determine the association between retinal microvascular changes and type of
stroke (lacunar and non-lacunar).
Methods:
This is a cross-sectional descriptive study conducted among stroke patients seen at the
Neurology Ward and Neurology Out-Patient Clinic of the UERM Memorial Medical Center. The
patients' demographic characteristics and risk factors were obtained through a standardized
questionnaire. Retinal photographs of both eyes were taken in eligible patients who consented to join
the study. Retinal vascular changes were identified and their association with the type of stroke was
determined.
Results :
Thirty-seven patients, 64% of whom had small artery occlusion type of lacunar stroke, were
enrolled in the study. The most prevalent retinal abnormalities for each type of stroke were AV
nicking and focal arteriolar narrowing. The prevalence of abnormal retinal findings between
patients with lacunar stroke and non-lacunar stroke were compared and showed insufficient
evidence to demonstrate a statistical significance between abnormal retinal findings and lacunar
stroke.
Conclusion
There is no significant association between abnormal retinal findings and lacunar
stroke.

We describe a 52-year old woman who developed one- and-a-half syndrome with an ipsilateral
trigeminal and facial nerve palsy from a lacunar infarct of the left paramedian pontine area
likely involving the median-paramedian perforators of the basilar artery.

BACKGROUND: It is well known that a lacunar infarction has characteristic clinical features and a relatively good prognosis. However, the significance of lesions in the parent artery of patients with lacunar syndrome as regard to the prognosis remains unsettled. METHODS: Using the data of consecutive patients with their first ischemic stroke and were followed longer than 1 year, were divided the patients by their clinical features and the results of the work-up was as follows; (1) mismatching [MM] group; lacunar syndrome and the presence of parent arterial lesion, (2) large artery artherosclerosis [LAD]; non-lacunar syndrome and the presence of parent arterial lesion, (3) no determined etiology [NE]; non-lacunar syndrome without parent arterial lesion, and (4) small artery disease [SAD]; lacunar syndrome without parent arterial lesion. Patients with a potential source of embolism were excluded from this study. The prognosis and recurrence rate of patients with the MM group were compared with those of other groups. RESULTS: A total of 176 patients were included; 56 LAD, 62 SAD, 22 MM and 36 NE groups. An unstable hospital course was more frequently found in LAD than in the other groups. The recurrence rate of the MM group (23%) was significantly higher than that of SAD (2%), but was similar to that of patients with non-lacunar syndrome (LAD 16%, NE 28%). CONCLUSIONS: Among patients with lacunar syndrome, the prognosis of those with parent arterial lesions was different from those without lesions. Therefore, a systematic work up of the stroke mechanism may be important in patients with lacunar syndrome.

We think that the clinical courses of lacurlar infarctions are somewhat different from those of cortical ones, because the ischemic penumbra, a keystone of acute infarct recovery, of the former is rnore limitted than that of the latter. Therefore, we analyzed the selected data, 38 cortical and 33 lacunar infarct patients, from Severance Stroke Registry which were recorded from May, 1989 to April, 1990, to demonstrate and compare the differences of the clinical courses and its influencing factors between the cortical and lacunar infarcts. Our results suggested as follows first, the initial neurologic deficits of cortical infarctions are rnore serious than those of lacunar infarctions, but with the better short-term improvements of tbe former, the short-term motor outcome between the two types of infarcts are not significantly different second, whiIe the short-term improvernent of cortical infarcs is influenced by initial hematocrit level, the short-term motor outcome and the degree of improvement of lacunar infarcts are influenced by the patient's age.

PURPOSE: To evaluate the utility of fluid-attenuated inversion recovery(FLAIR) sequence by comparing thesignal intensities in various cerebral lesions with those on T2-weighted MR imaging. MATERIALS & METHODS: In 41patients who showed different signal intensities between T2-weighted images and FLAIR sequences, we reviewed theVirchow-Robin space(VRS), acute or chronic infarctions including lacunar cavities, and postoperativeencephalomalacia. In all patients, the location, shape and size of abnormal signal intensities were evaluated. RESULTS: The hyperintensities of VRS and lacunar infarctions on T2-weighted imaging appeared as hypointensitieson FLAIR imaging. The hyperintense rims or crescents around lacunar cavities were only detected on FLAIR imaging.The extent of acute and chronic infarctions with homogenous hyperintensities seen on T2-weighted images was welldelineated on FLAIR imaging. Postoperative encephalomalacia and adjacent lesions showed low and high signalintensities, respectively, on FLAIR imaging, though they were hyperintense on T2-weighted images. CONCLUSION: ForVRS, infarction and encephalomalacia, FLAIR provides images that are superior to T2-weighted images, and may thusbe useful as an additional MR sequence in various cerebral lesions.

A case with a true posterior communicating artery aneurysm is reported, who had been managed by early surgical neck clipping and post-operative intensive cares for numerous complications. The small saccular aneurysm was located at the proximal posterior communicating artery and directed superiorly. A lacunar infarct developed at right anterior thalamus post-operatively, which had resulted probably from the occlusion of a fine posterior communicating arterial perforator. Aneurysms of the posterior communicating artery itself are saccular or fusiform. Great cares should be taken in surgical aneurysmal neck clipping to avoid any injury of the perforators and the oculomotor nerve;trapping of the posterior communicating artery to treat fusiform or wide-necked aneurysms will result in unpredictable outcomes.
