Using the positions of the eyelids is an effective and contact-free way for the measurement of startle induced eye-blinks, which plays an important role in human psychophysiological research. To the best of our knowledge, no methods for an efficient detection and tracking of the exact eyelid contours in image sequences captured at high-speed exist that are conveniently usable by psychophysiolog...

PURPOSE To compare morphometric data of eyelid fissure using computerized image analysis before and after application of botulinum toxin type A in patients with eyelid retraction caused by dysthyroid orbitopathy in acute stage. METHODS This was a prospective study with 12 individuals that received transcutaneous 5 UI/0.1 ml injection of botulinum toxin in the upper eyelid. They were examined ...

An eyelid closure in response to some stimulus is a blink reflex (BR), which is normally isolated. In humans and primates, the closing is bilateral while in other animals, mostly those with eyes set laterally, the closure is frequently unilateral. In clinical practice, a BR is characteristically provoked by light corneal or eyelash touching or glabellar tapping. The British physician Overrend f...

PURPOSE To report the outcomes of acquired lower eyelid epiblepharon after various surgeries in thyroid associated ophthalmopathy (TAO) patients. METHODS A retrospective review of the medical records of 53 TAO patients with acquired lower eyelid epiblepharon between October 1999 and June 2011 was performed. Data were collected on demographics, type of lower eyelid epiblepharon, the detailed s...

PURPOSE To establish the relationship between upper eyelid saccades and upper eyelid pursuit movements. METHODS Upper eyelid saccades and periodic sinusoidal upper eyelid pursuit movements were recorded in a sample of controls and patients with Graves upper eyelid retraction. A video-computerized system was used to register both types of movements that accompanied 60 degrees of eye rotation a...

RATIONALE Eyelids are very susceptible area for non-melanoma skin cancers; among that, basal cell carcinoma has the highest incidence (almost 90% of malignant eyelid tumors) and 50-60% of eyelid basal cell carcinomas appear on inferior eyelid. OBJECTIVE To analyze clinical features of inferior eyelid basal cell carcinoma and to determine the efficacy of surgical treatment with frozen sectionc...

Mechanisms that regulate the growth of eyelashes have remained obscure. We ascertained two families from Pakistan who presented with familial trichomegaly, or extreme eyelash growth. Using a combination of whole exome sequencing and homozygosity mapping, we identified distinct pathogenic mutations within fibroblast growth factor 5 (FGF5) that underlie the disorder. Subsequent sequencing of this...

Phthiriasis palpebrarum is an infestation of the eyelashes caused by the louse Pthirus pubis (Linnaeus, 1758). We report a case of phthiriasis palpebrarum in a 6-year-old girl, which was initially misdiagnosed as allergic blepharoconjunctivitis. Parasites and their nits were found adhering to the eyelashes and eyelids of her right eye as well as scalp hairs. No abnormality was found in the left...
