Human replicas may elicit unintended cold, eerie feelings in viewers, an effect known as the uncanny valley. Masahiro Mori, who proposed the effect in 1970, attributed it to inconsistencies in the replica's realism with some of its features perceived as human and others as nonhuman. This study aims to determine whether reducing realism consistency in visual features increases the uncanny valley...

OBJECT The supraorbital approach through an eyebrow incision offers the opportunity to access a wide variety of lesions of the anterior, middle, and even the posterior fossa. The minimally invasive keyhole craniotomy limits brain exploration and retraction and offers the potential for improved surgical outcomes and reduced approach-related complications. Patient satisfaction, however, has not y...

The lateral open forehead lift technique uses 2 scalp incisions to elevate and suspend the lateral eyebrows, and 2 upper blepharoplasty incisions to access the muscles that produce glabellar frown lines and depress the medial eyebrows. Advantages of this technique are that side effects associated with the coronal incision, such as hair loss and overelevation of the medial eyebrow, are avoided.

Use of barbed threads, available with uni- and bi-directional cogs or barbs, is a semi-invasive method of lifting sagging skin of the face. Areas treated with this method include the eyebrows, the cheeks, the jowls and the neck. Ease of use and a shorter down-time have made their use popular. Specific indications, operative procedures, risks and complications are described and some clinical res...

Does an assimilative illusion like the Delboeuf illusion occur in the human face? We investigated factors that might influence the perceived size of the eyes in a realistic face. Experiment 1 manipulated the position of the eyebrows (high or low), the presence/absence of eye shadow, and the viewing distance (0.6 m or 5 m), then measured the perceived eye size using a psychophysical method. The ...

A 15yearold boy suffered from blunt trauma to the left eyebrow (Figure 1A arrow). Three hours after the trauma, he had a visual acuity (VA) of no light perception (NLP) in the left eye. Relative afferent pupillary defect was positive in the left eye. The intraocular pressure of each eye was 15 mm Hg. Anterior segment examination results were unremarkable. Funduscopic examination results were no...

INTRODUCTION In evaluation for blepharoplasty, patients often desire improved cosmesis and/or correction of visual field deficits. However, patients are usually unaware of eyelid or brow asymmetry. Furthermore, the prevalence of eyelid and brow asymmetry is infrequently reported in the medical literature. PURPOSE To determine the prevalence of brow and eyelid asymmetry in patients evaluated f...

Eyelid anatomy, including thickness measurements, was examined in numerous age groups. The thickest part of the upper eyelid is just below the eyebrow (1.127±238 µm), and the thinnest near the ciliary margin (320±49 µm). The thickness of skin at 7 mm above the eyelashes was 860±305 µm. The results revealed no significant differences among the age groups. Fast fibers (87.8±3.7%) occupied a signi...
