PURPOSE The aim of this study was to clarify the differences between single and double eyelid structures quantitatively using an ultrasound biomicroscopy. DESIGN A single-center observational study. METHODS Upper eyelids of Asian volunteers were evaluated with a 50-MHz ultrasound biomicroscopy. The skin-orbicularis oculi complex (SOOC), levator aponeurosis, Mueller muscle-conjunctival compl...

Historically, lower eyelid blepharoplasty has been a challenging surgery fraught with many potential complications, ranging from ocular irritation to full-blown lower eyelid malposition and a poor cosmetic outcome. The prevention of these complications requires a detailed knowledge of lower eyelid anatomy and a focused examination of the factors that may predispose to poor outcome. A thorough p...

PURPOSE To investigate the causes of lower eyelid retraction and evaluate the outcomes of various surgical procedures. METHODS We conducted a retrospective medical record review of patients who underwent lower eyelid retraction surgery performed by a single surgeon at Kim's Eye Hospital between 2006 and 2013. We investigated the causes of lower eyelid retraction, clinical history, characteris...

scribed in 1960 (1), is a very rare disease because the bony pelvis provides an effective shield against external injury. Thus, pelvic ring fracture or hip dislocation (1) usually precedes lumbosacral nerve root avulsion. Isolated lumbosacral nerve root avulsion is so rare that, to the best of our knowledge, only nine cases have been reported in the English literature to date (2). The diagnosti...

Fractures of the tibia through the proximal epiphysis are rare. This injury usually results from severe direct or indirect force about the knee, and has not been described as resulting from a patellar tendon avulsion injury. Four patients presented with five avulsion fractures of the proximal tibial epiphysis. All were older adolescent males who had been engaged in jumping sports when the injur...

The purpose of the present study was to objectively quantify the spectral transmittance of the eyelid. Reported here are data acquired using a technique that was developed to provide practical and accurate measurements of eyelid transmittance across the visible portion of the electromagnetic spectrum. The empirical data were analyzed in terms of the absorption and scattering characteristics of ...

Purpose. To investigate static upper eyelid pressure and contact with the ocular surface in a group of young adult subjects. Methods. Static upper eyelid pressure was measured for 11 subjects using a piezoresistive pressure sensor attached to a rigid contact lens. Measures of eyelid pressure were derived from an active pressure cell (1.14-mm square) beneath the central upper eyelid margin. To i...

The lower eyelid retractors consist of double layers, the posterior layer of which is the main tractional component. Therefore, shortening of the posterior layer of the lower eyelid retractors causes lower eyelid retraction or cicatricial entropion. Based on this concept, we report a modified lower eyelid lengthening surgery involving complete recession of the posterior layer of the lower eyeli...

in this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (epl) and flexor pollicis longus (fpl) tendon avulsion from the tenomuscular junction. after metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. transfer of e...
