Large area eyelid defects induced by human biting was rare. A 43-year-old man was bited by a human. His Blepharocoloboma size was 60% percent of the upper eyelid, the horizontal defect length of defect area was 25mm, the vertical height was 5mm,a small mass like lateral eyelid tissue was left on the Lateralis lid margin. The toughness of this lateral eyelid tissue was enough to support the late...

PURPOSE A youthful female upper eyelid contour includes a concave medial portion of the upper eyelid along with a fuller, convex lateral eyelid. The skin in the lateral eyelid is tight without hooding. This is a sigmoid shape in 3-dimensional terms. With aging, fatty herniation medially along with redundant, hooded, ptotic lateral skin creates the exact opposite eyelid curve. The sigmoid blepha...

Purpose: to determine the acoustic characteristics ofvarious types o f tissue scarringfor differentiation post-traumatic eyelid scars. Materials and methods. 67 patients aged 32 (mean age 47.2 ± 9.5) with scarring were examined by ultrasound gray-scale B-scan of tissues in SmallPart mode echodensitometry (Voluson Е 8 GE). The duration period all was more than 12 months. Results. Objective echog...

Eyelid margin is one of the most challenging anatomic regions in human body and eyelid tumors raise special difficulties field periocular surgery based on anatomical, histological aesthetic points view.

Purpose: To review primary literature on ocular and orbital injury secondary to all-terrain vehicles (ATVs). Methods: A Medline search of English language literature. Results: Very few studies detail ocular and orbital manifestations of ATV crashes. The most common ocular injuries included orbital fractures and eyelid lacerations. Less common but more severe injuries included traumatic optic ne...

INTRODUCTION Ocular injuries commonly involve the lacrimal system. CASE A 14-year-old male had an eyelid injury with a canalicular tear. An angiocatheter tube was used as a stent for canalicular reconstruction. The focus of this report is on the method used, as well as the material for the repair in a rural hospital. CONCLUSION Angiocatheter tube can be a suitable alternative to silicone tu...

OBJECTIVE To determine the force requirements, optimal vector, and appropriate materials of a novel eyelid sling device that will be used to rehabilitate eyelid closure (blink) in congenital or acquired permanent facial paralysis with an artificial muscle. METHODS The force required to close the eyelids in human cadavers (n = 6) were measured using a load cell system. The eyelid sling using e...

How Purkinje cell (PC) activity may be altered by learning is central to theories of the cerebellum. Pavlovian eyelid conditioning, because of how directly it engages the cerebellum, has helped reveal many aspects of cerebellar learning and the underlying mechanisms. Theories of cerebellar learning assert that climbing fiber inputs control plasticity at synapses onto PCs, and thus PCs control t...
