Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant genetic disorder involving the abnormal communication of vascular structures. HHT typically presents with recurrent epistaxis and telangiectasis of the nasal and buccal mucosa, tongue, and lips. More serious manifestations of this disease include cerebral, pulmonary, gastrointestinal, and hepatic arteriovenous malformations. T...

Two experiments that examined the characteristics of information extracted from a parafoveal letter string by the saccadic system are reported. In Experiment 1, we observed the effect of the orthographic legality of the initial letter sequence on landing positions. The deviation of landing positions towards an orthographically illegal letter sequence was shown to occur in saccades when subjects...

Participants' eye movements were measured while reading Chinese sentences in which target-word frequency and the availability of parafoveal processing were manipulated using a gaze-contingent boundary paradigm. The results of this study indicate that preview availability and its interaction with word frequency modulated the length of the saccades exiting the target words, suggesting important f...

Potential sources for the discrepancy between the letter position effects in T. R. Jordan, S. M. Thomas, G. R. Patching, and K. C. Scott-Brown's (2003; see record 2003-07955-013) and D. Briihl and A. W. Inhoff s (1995; see record 1995-20036-001) studies are examined. The authors conclude that the lack of control over where useful information is acquired during reading in Jordan et al.'s study, ...

We report a boundary paradigm eye movement experiment to investigate whether the linguistic category of a two-character Chinese string affects how the second character of that string is processed in the parafovea during reading. We obtained clear preview effects in all conditions but, more importantly, found parafoveal-on-foveal effects whereby a nonsense preview of the second character influen...

Parafoveal function is important for daily visual tasks such as reading. Here the variability in cone density along the four cardinal meridians in parafoveal regions of the retina was investigated in vivo using an adaptive optics fundus camera. Ten healthy normal trichromatic individuals were included in the study. There were significant differences in cone density between individuals at all fo...

Although femoroacetabular impingement (FAI) syndrome is included in the etiology of lesions involving the acetabular labrum and acetabular cartilage, it is one of many possible reasons behind osteochondral lesions in the femoral head. Herein, we present clinical findings and outcomes of two cases with osteochondral defects and cam type impingement of femoral head. Both cases underwent autologou...
