iris recognition is one of the most reliable methods for identification. in general, itconsists of image acquisition, iris segmentation, feature extraction and matching. among them, iris segmentation has an important role on the performance of any iris recognition system. eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. in this pa...

Purpose. Meibomian gland dysfunction (MGD) can lead to abnormalities in the composition and function of tear film, resulting in dry eye. Eyelid hygiene is a key to management of MGD. We tested a novel eyelid shampoo (Eye Shampoo Long, ESL) for its ability to maintain lid hygiene. This shampoo is nonirritating and can potentially lengthen eyelashes. This study was aimed to evaluate the efficacy ...

To reduce the influence of the eyelid for the iris recognition rate, an eyelid detection algorithm for the iris recognition is proposed. The grayscale morphological operations are employed to remove the interference of the eyelash and the light spot to the eyelid region. The points of the minimum grayscale value of each column in the eyelid region are extracted as edge points. The least squares...

PURPOSE To prospectively investigate adverse reactions to bimatoprost in Japanese patients with glaucoma or ocular hypertension. We also examined patient attitudes to adverse reactions via a questionnaire. METHODS Fifty-two Japanese patients with glaucoma or ocular hypertension were enrolled. Iridial, eyelid, and eyelash photographs were taken before and at 6 months after bimatoprost treatmen...

purpose: to evaluate the effect of preoperative eyelash trimming on periocular bacterial flora. methods: one hundred patients divided into two groups. fifty cases (group 1) had eyelash trimming prior to phacoemulsification and other fifty patients (group 2) did not. none of the study participants had been diagnosed as having an active ocular infection prior to surgery. patients taking topical a...

PURPOSE To evaluate the effect of redundant lower eyelid skin on the eyelash direction in epiblepharon. MATERIALS AND METHODS Asian patients with epiblepharon participated in this study. The lower eyelid skin was pulled downward in the upright position with the extent just to detach from eyelash roots, and the direction of the eyelashes was examined. These evaluations were repeated before sur...

Background: Latanoprost, a prostaglandin F 2a analogue, is an intraocular pressure lowering drug used in the treatment of glaucoma. Increase in eyelash number, length, pigmentation, curvature is reported after using topical Latanoprost in these patients. The aim of this study was to evaluate the effect of Latanoprost ophthalmic solution on eyelash regrowth in patients with alopecia areata.Metho...

A 9-year-old girl of nonconsanguineous Moroccan parents, presented with an isolated long white eyelash in the upper left eyelid for 18 months. This eyelash was a terminal hair and presented no underlying skin lesions [Figures 1 and 2]. At the moment of presentation, the eyelash was only 2 cm long because she had it removed 3 weeks before. His father reported that this eyelash could grow up to 5...

PURPOSE To evaluate eyelid margin alterations in ectropion carriers. METHODS An observational study was done involving 53 eyelid ectropion patients and 25 individuals with dermochalasis (control group). Eyelash position and margin inflammation were observed using digital images. The data were submitted to statistical analysis. RESULTS Patients with ectropion showed a decreased number of eye...

Background Lower eyelid incisions are widely used for the orbital approach in periorbital trauma and aesthetic surgery. In general, the subciliary approach is known to cause disposition of the lower eyelid by scarring the anterior lamella in some cases. On the other hand, many surgeons believe that a transconjunctival approach usually does not result in such complications and is a reliable meth...
