Abstract
OBJECTIVE To study ophthalmological manifestations in a well-characterized primary antiphospholipid syndrome (PAPS) cohort (APS-Rio) and compare them with a healthy control group. METHODS We examined PAPS patients and controls with an extensive ophthalmological evaluation, which included anamnesis, visual acuity, slit-lamp biomicroscopy, binocular indirect ophthalmoscopy, and retinography of the anterior and posterior segments of the eye. PAPS group also underwent angiography exam and optical coherence tomography using spectral domain technology (SD-OCT). RESULTS 98 PAPS patients and 102 controls were included. The most common symptom in PAPS was amaurosis fugax (34.7% vs. 6.9%; p = .001). In the multivariate analyses, Raynaud's phenomenon was associated with amaurosis fugax (OR 3.71, CI:1.33-10.32; p = .012), and livedo correlated with hemianopia (OR 6.96, CI:1.11-43.72, p = .038) and diplopia (OR 3.49, CI:1.02-11.53, p = .047). After ophthalmological evaluation, 84 PAPS patients had ocular involvement (1.0% glaucoma, 94.0% posterior findings, 62.7% anterior findings, and 56.6% both posterior and anterior findings). Vascular tortuosity was more frequent in the PAPS group (63.2% vs. 42.2%; p = .002), as well as peripheral tortuosity (29.6% vs. 7.8%; p < .001). After excluding patients with atherosclerotic risk factors, peripheral vascular tortuosity was still statistically associated with PAPS (35.0 vs. 7.8%, p < .001). Triple positivity was more frequent in PAPS patients with peripheral vascular tortuosity than in those without this ocular finding (34.5% vs. 15.9%, p = .041). CONCLUSION Vasomotor phenomena are importantly related to ocular symptoms in PAPS. Vascular tortuosity was a frequent finding in PAPS patients. Peripheral vascular tortuosity was associated with triple positivity and might be a biomarker of ischemic microvascular retinopathy due to PAPS.

Abstract
The patient, a fifty nine year old male, was admitted to the ward with symptoms of inferior wall myocardial infarction with ST segment elevation combined with intermittent right side sight loss. Despite typical resting stenocardial chest pain, ST segment elevation in ECG, transient symptoms of acute heart failure and slightly elevated myocardial necrosis biomarkers, coronarography did not reveal obvious source of myocardial ischemia. Moreover, echocardiography did not confirm decreased ejection fraction. However further research confirmed critical stenosis of the left internal carotid artery and chronic occlusion of the right internal carotid artery. Several questions were raised during diagnostic process including: the cause of cardiac ischemia and the cause of cerebral ischemia. Clinical data analysis and available literature allowed authors to exclude cerebral ischemia as a source of ECG ischemic changes and to establish transient myocardial ischemia causing circulatory decompensation amplified by carotid arteries atherosclerosis as the source of neurological symptoms.

Abstract
BACKGROUND To determine the frequency of essential cardiovascular risk factors in different vascular ocular diseases. - METHODS We compiled cardiovascular risk factor findings (RFs) from 416 patients with non-inflammatory ocular vascular occlusions in a retrospective study: 134 patients with BRAO, 253 patients with CRAO, and 29 patients with hemi-CRAO. 274 (65.9 %) male and 142 (34.1 %) female patients were examined. Mean age of all patients was 66 years (range: 18-90). The right eye was involved in 221 (53.1 %), left eye in 193 (46.4 %), and both eyes in 2 patients (0.5 %). - RESULTS Cardiovascular risk factors (RFs) were found in 243 patients. Three hundred and eight (308) out of 406 patients (75.9 %) presented with arterial hypertension. Hypertension was present in 96 patients with BRAO (73.8 %), in 197 patients with CRAO (79.8 %), and in 15 patients with hemi-CRAO (78.9 %). - RFs such as arterial hypertension, carotid artery diseases, diabetes mellitus, hyperlipidemia, hyperuricemia, and chronic smoking did not differ statistically between patients with BRAO, CRAO or hemi--CRAO. But visible emboli in retinal arteries were observed in patients with BRAO (47 %,), or hemi-CRAO (41.4 %), much more often than in patients with CRAO (11.1 %). - CONCLUSIONS No statistical differences between the RFs of patients with BRAO, CRAO, or hemi-CRAO were noted. We maintain that every patient with retinal arterial obstruction should undergo extensive examination of essential RFs.

Abstract
BACKGROUND Retinal infarction and transient monocular blindness (TMB) are associated with an increased risk of future ischaemic stroke. Little information is available on the type of subsequent ischaemic strokes that may occur (anterior or posterior circulation and small vessel or large vessel). AIM To analyse the type of stroke after TMB. METHODS Patients with transient or permanent retinal ischaemia were selected from three prospective studies: the Dutch TIA Trial, the Dutch Amaurosis Fugax Study and the European/Australian Stroke Prevention in Reversible Ischaemia Trial. On follow-up the type of stroke was classified according to the supply territory and the type of vessel involved. RESULTS 654 patients were included. During a mean follow-up of 5.2 years, 42 patients were found to have had a cerebral or retinal infarct, of which 27 occurred in the carotid territory ipsilateral to the symptomatic eye, 9 in the territory of the contralateral carotid artery and 6 were infratentorial strokes. Thirty patients had a large-vessel infarct, four had a small-vessel infarct and eight had a retinal infarct. Characteristics associated with a notable increased risk for subsequent stroke or retinal infarction were age > or = 65 years, a history of stroke, a history of intermittent claudication, diabetes mellitus, Rankin score > or = 3, more than three attacks of retinal ischaemia and any degree of ipsilateral carotid stenosis on duplex ultrasonography observation. CONCLUSION Ischaemic strokes after TMB or retinal infarction were found to be mainly large-vessel infarcts in the territory of the ipsilateral carotid artery. TMB and retinal infarction are probably manifestations of large-vessel disease.

Abstract
The aim of this study was to prospectively assess associations between amaurosis fugax, inherited thrombophilia, and acquired thrombophilia. Thrombophilia and hypofibrinolysis were studied in 11 cases (eight women, three men; all white) with amaurosis fugax, 57 +/- 17 years old, selected by the absence of abnormal brain magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), magnetic resonance venography (MRV), ipsilateral internal carotid artery plaque, atrial fibrillation, or cardiac thrombus. Cases were compared to 78 healthy adult white controls (53 +/- 18 years old) for serologic measures, and by polymerase chain reaction to 248 healthy white controls (78 adults, 170 children) for gene mutations. All 11 cases had one or more familial thrombophilic coagulation disorder including one heterozygous for the G1691A factor V Leiden mutation, two with low free protein S, four with high factor VIII, three with resistance to activated protein C, three homozygous for the C677T methylenetetrahydrofolate reductase (MTHFR) mutation, two compound C677T-A1298C MTHFR heterozygotes, and three with hypofibrinolytic 4G4G homozygosity for the PAI-1 gene. The case with factor VIII of 160% had two other thrombophilias (compound MTHFR C677T-A1298C heterozygosity, resistance to activated protein C), and hypofibrinolytic high Lp(a). Thrombophilic C677T MTHFR homozygosity or compound C677T-A1298C heterozygosity was present in five of 10 (50%) cases vs. 30 of 248 (12%) controls, Fisher's p (p(f)) = .005. Thrombophilic factor VIII was high in four of 10 (40%) cases vs. 0 of 38 controls, p(f) = .001. Thrombophilic hyperestrogenemia in five of the eight women (four exogenous estrogen, one pregnant) may have interacted with inherited thrombophilia-hypofibrinolysis, promoting thrombus formation. In cases selected by the absence of abnormal brain magnetic resonance imaging, significant ipsilateral internal carotid artery plaque, atrial fibrillation, or cardiac thrombus, we speculate that amaurosis fugax can be caused by reversible (by anticoagulation) retinal artery thrombi associated with heritable thrombophilia and/or hypofibrinolysis, often augmented by estrogen-driven acquired thrombophilia.

Abstract
OBJECTIVE To estimate the rates and predictors of survival and recurrence among residents of Olmsted County, Minnesota, who received an Initial diagnosis based on 2-dimensional color Doppler echocardiography of moderate or severe mitral or aortic stenosis or regurgitation and who experienced a first ischemic stroke, transient ischemic attack (TIA), or amaurosis fugax. PATIENTS AND METHODS At the Mayo Clinic in Rochester, Minn, we used the resources of the Rochester Epidemiology Project to identify Individuals who met the criteria for inclusion in the study and to verify exclusion criteria. The study included all residents of Olmsted County, Minnesota, who experienced a first Ischemic stroke, TIA, or amaurosis fugax within 30 days of or subsequent to receiving a first-time 2-dimensional color Doppler echocardlography-based diagnosis of moderate or severe mitral or aortic stenosis or regurgitation between January 1, 1985, and December 31, 1992. The Kaplan-Meier product-limit method was used to estimate the rates of subsequent stroke and death after the ischemic stroke, TIA, or amaurosis fugax. The Cox proportional hazards model was used to assess the effect of several potential risk factors on subsequent stroke occurrence and death. RESULTS For the 125 patients in the study, the Kaplan-Meier estimates of the risk of death and the risk of stroke at 2-year follow-up were 38.6% (95% confidence interval [CI], 29.9%-47.5%) and 18.5% (95% CI, 10.0%-27.0%), respectively. Compared with the general population, death rates were significantly Increased (standardized mortality ratio = 1.75; 95% CI, 1.38-2.19; P < .001) but rates of subsequent stroke occurrence were not (standardized morbidity ratio = 1.20; 95% CI, 0.75-1.84; P = .40). After adjustment for age, sex, and cardiac comorbidity, neither the type nor severity of valvular heart disease was an independent determinant of survival or subsequent stroke occurrence. CONCLUSIONS Patients with mitral or aortic valvular heart disease who experience Ischemic stroke, TIA, or amaurosis fugax have Increased rates of death, but not recurrent stroke, compared with expected rates. Other cardiovascular risk factors are more important determinants of survival In these patients than the type or echocardiographic severity of the valvular heart disease.

Abstract
OBJECTIVES Hemispheric neurologic symptoms, amaurosis fugax, and Hollenhorst plaques at eye examination are standard indications for carotid imaging to identify carotid artery occlusive disease (CAOD). Previous reports have suggested that other ocular findings, such as retinal artery occlusion and anterior ischemic optic neuropathy, are associated with CAOD. However, the predictive value of ocular findings for the presence of CAOD is controversial. The purpose of this study was to define the predictive value of ocular symptoms and ophthalmologic examination in identifying significant CAOD. METHODS Over 3 years 145 patients were referred for carotid imaging on the basis of ocular indications in 160 eyes. Forty patients were excluded because of concurrent non-ocular indications for carotid imaging, leaving 105 patients referred exclusively for ocular indications to evaluate. Ophthalmologic history and eye examination were correlated with carotid duplex ultrasound findings. RESULTS Amaurosis fugax was associated with a positive scan in 20.0% of carotid arteries (P =.022). Hollenhorst plaques at fundoscopic examination were associated with a positive scan in 18.2% of carotid arteries (P =.02). Ocular findings exclusive of Hollenhorst plaques were particularly poor predictors of CAOD, inasmuch as only 1 of 64 arteries (1.6%) had significant ipsilateral internal carotid artery stenosis (P =.022). Venous stasis retinopathy was the only ocular finding other than Hollenhorst plaques with any predictive value (1 of 5 scans positive; positive predictive value, 20.0%). CONCLUSIONS Ocular symptoms and findings are poor predictors of CAOD. Amaurosis fugax, Hollenhorst plaques, and venous stasis retinopathy demonstrated moderate predictive value, whereas all other ocular findings demonstrated no predictive value in identifying CAOD.

Abstract
BACKGROUND Optometrists often encounter patients with ocular signs and/or symptoms suggestive of carotid artery disease, but criteria for eye care practitioners concerning when to order carotid studies are not well established. A retrospective study in an optometry clinic was performed to determine if certain ocular findings and associated systemic risk factors were associated with hemodynamically significant carotid artery stenosis (HSCAS). METHODS A retrospective analysis was performed on all patients examined in the optometry clinic at the Sepulveda Ambulatory Care Center from January 1, 1998 through December 31, 1999 to identify all patients who had carotid studies ordered. Charts were then reviewed to determine the ocular finding that prompted the carotid study. Statistical analysis using an odds-ratio was performed to determine whether any ocular sign/symptom or systemic risk factor was associated with HSCAS. RESULTS Of 3822 patients, 48 (1.26%) had carotid studies ordered. Eight (17%) had HSCAS of >50% and symptomatic patients were 1.6 times more likely to have HSCAS than asymptomatic patients. Patients with HSCAS were 1.8 times more likely to have retinal vascular occlusions, 1.9 times more likely to have normotensive glaucoma, 2.4 times more likely to have peripheral retinal hemorrhages, and 2.6 times more likely to be smokers, although none of these factors were found to be a statistically significant indicator of HSCAS. However, the number of systemic diseases tended to be greater for the HSCAS patients compared with the non-HSCAS patients (HSCAS median = 3.5 and the non-HSCAS median = 2, p = 0.049). CONCLUSION Although no single ocular or systemic risk factor was found to be a statistically significant indicator of HSCAS, the number of systemic disease risk factors tended to be greater for the HSCAS patients compared with the non-HSCAS patients (p = 0.049). An extensive literature review was also performed to help establish guidelines for when to order carotid studies on the basis of ocular signs and/or symptoms as well as the presence of additive associated systemic risk factors.

Abstract
BACKGROUND AND PURPOSE Carotid artery disease can cause chronic retinal ischemia, resulting in transient or permanent blindness, pupillary reflex dysfunction, and retinal degeneration. This experiment investigated the effects of chronic retinal ischemia in an animal model involving permanent carotid occlusion. The time course of retinal pathology and the role of light in this pathology were examined. METHODS Sprague-Dawley rats underwent permanent bilateral occlusion of the common carotid arteries or sham surgery. Half of the animals were postsurgically housed in darkness, and half were housed in a 12-hour light/dark cycle. Animals were killed at 3, 15, and 90 days after surgery. Stereological techniques were used to count the cells of the retinal ganglion cell layer. Thy-1 immunoreactivity was assessed to specifically quantify loss of retinal ganglion cells. The thicknesses of the remaining retinal sublayers were measured. Optic nerve degeneration was quantified with the Gallyas silver staining technique. RESULTS Permanent bilateral occlusion of the common carotid arteries resulted in loss of the pupillary reflex to light in 58% of rats. Eyes that lost the reflex showed (1) optic nerve degeneration at 3, 15, and 90 days after surgery; (2) a reduction of retinal ganglion cell layer neurons and Thy-1 immunoreactivity by 15 and 90 days; and (3) a severe loss of photoreceptors by 90 days when postsurgically housed in the light condition only. CONCLUSIONS Ischemic damage to the optic nerve caused loss of pupillary reflex and death of retinal ganglion cells in a subset of rats. Subsequently, light toxicity induced death of the photoreceptors.

Abstract
To assess which features of transient monocular blindness (TMB) are associated with atherosclerotic changes in the ipsilateral internal carotid artery (ICA), 337 patients with sudden, transient monocular loss of vision were prospectively studied. History characteristics of the attack were compared with the presence of atherosclerotic lesions of the ipsilateral ICA. All patients were directly interviewed by a single investigator. Of all patients, 159 had a normal ICA on the relevant side, 33 had a stenosis between 0%-69%, 100 had a stenosis of 70%-99%, and 45 had an ICA occlusion. An altitudinal onset or disappearance of symptoms was associated with atherosclerotic lesions of the ipsilateral ICA. A severe (70%-99%) stenosis was also associated with a duration between 1 and 10 minutes, and with a speed of onset in seconds. An ICA occlusion was associated with attacks being provoked by bright light, an altitudinal onset, and the occurrence of more than 10 attacks. Patients who could not remember details about the mode of onset, disappearance, or duration of the attack were likely to have a normal ICA. Our findings may facilitate the clinical decision whether or not to perform ancillary investigations in these patients.

Abstract
Saphenous vein patch angioplasty is the preferred method of closure of the arteriotomy site during carotid endarterectomies. A major early complication of the saphenous vein patch is rupture of the patch which can occur within the first few postoperative days. The reported incidence varies from 0.5% to 4%. Patch rupture can result in stroke or death. From May 1992 to April 1999, autogenous everted double-layer saphenous vein patch was used in 192 carotid endarterectomies performed on 168 patients; 96 males and 72 females. The age range was from 54 to 94 years with a mean age of 73 years. The saphenous vein is harvested from the ankle. It is everted and then used as a double-layer patch. The follow-up period was from 3 to 74 months, with a mean of 24 months. Postoperatively, there were no patch ruptures or late aneurysm formation. There was no perioperative mortality. Everted double-layer saphenous vein patch eliminates the risk of patch rupture and at the same time retains the benefits of an autologous nonprosthetic graft. Saphenous vein from the ankle can be safely used for carotid angioplasty as a double layer patch.
