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...

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...

Purpose. To describe the use of the temporoparietal fascial flap (TPF) in the reconstruction of extensive lower eyelid defects in a functioning eye. Methods. We present a surgical case report of a 73-year-old female with melanoma of the left lower eyelid. The lower eyelid was resected, and a composite nasal cartilage-mucosa graft, a skin graft, and a TPF were used to reconstruct the lower eyeli...

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...
