The iris recognition is a biometrics technology to extract and code an unique iris feature from human eye image. Also, it includes the technology to compare with other's various iris stored in the system. On the other hand, eyelashes in iris image are a external factor to affect to recognition rate of iris. If eyelashes are not removed exactly from iris area, there are two false recognitions that recognize eyelashes to iris features or iris features to eyelashes. Eventually, these false recognitions bring out a lot of loss in iris informations. In this paper, in order to solve that problems, we removed eyelashes by gabor filter that using for analysis of frequency feature and improve preservation rate of iris informations. By novel method to extract various features on iris area using angle, frequency, and gaussian parameter on gabor filter that is one of the filters for analysing frequency feature for an image, we could remove accurately eyelashes with various lengths and shapes. As the result, proposed method represents that improve about 4% than previous methods using GMM or histogram analysis in iris preservation rate.

Regarding the figure painting of the T'ang period, by Yeomipbon, a representative painter of the early T'ang period, shows a traditional painting style. Figure paintings of the Prosperous T'ang period, influenced by Odoja's painting style, are characterized as illustrating the lives of noble women delicately with brilliant colors. They include Janghwon's and in which Chinese traditional and Western painting styles were combined. , and , which were painted by Jubang in the mid T'ang period, were the developmentally succeeded the figure painting style of the previous times, illustrating even the psychological and emotional states of painted figures in a sophisticated way. Skin make-ups shown in figure paintings of the T'ang period are mostly baekjang in type. Besides, other different types of the make=up such as bihajang, dohwajang and juwoonjang can be seen. The paintings, show that the tone of skin got more and more red as the times moved from the early to the late T'ang periods because rouge was more and more used as the times passed between the periods. As a type of forehead make-up, aekhwang is found in Janghwon's and of the late T'ang period. Hwajeon is seen in lots of figure paintings made between the Prosperous the late T'ang periods. Most eyelid make-ups shown in the figure paintings are round-shaped wolmi and yuhyeopmi in type. Besides, other creative types like gyeyeopmi, paljami and iljami are found. Lips are found made up clearer and more red as the times went from the early and the late T'ang periods. The types of cheek make-up like sahong and jangyeop can't be found in figure paintings of the T'ang period.
Purpose: Mobius syndrome is a rare congenital disorder characterized by facial diplegia and bilateral abducens palsy, which occasionally combines with other cranial nerve dysfunction. The inability to show happiness, sadness or anger by facial expression frequently results in social dysfunction. The classic concept of cross facial nerve grafting and free muscle transplantation, which is standard in unilateral developmental facial palsy, cannot be used in these patients without special consideration. Our experience in the treatment of three patients with this syndrome using transfer of muscles innervated by trigeminal nerve showed rewarding results. Methods: We used bilateral temporalis muscle elevated from the bony temporal fossa. Muscles and their attached fascia were folded down over the anterior surface of the zygomatic arch. The divided strips from the attached fascia were passed subcutaneously and anchored to the medial canthus and the nasolabial crease for smiling and competence of mouth and eyelids. For the recent 13 years the authors applied this method in 3 Mobius syndrome cases- 45 year-old man and 13 year-old boy, 8 year-old girl. Results: One month after the surgery the patients had good support and already showed voluntary movement at the corner of their mouth. They showed full closure of both eyelids. There was no scleral showing during eyelid closure. Also full closure of the mouth was achieved. After six months, the reconstructed movements of face were maintained. Conclusion: Temporalis muscle transfer for Mobius syndrome is an excellent method for bilateral reconstruction at one stage, is easy to perform, and has a wide range of reconstruction and reproducibility.

A 10-year-old, intact female Yorkshire terrier was presented with right side facial swelling for 3 days and periocular swelling had progressed over the last 24 hours. On physical examination, periocular and infraorbital swelling were observed around right maxillary region. Severe ocular discharge and protrusion of the 3rd eyelid were observed. The patient was diagnosed as periapical abscess around the root of right upper first molar based on the skull radiography. Affected tooth was extracted using closed technique. Systemic corticosteroid and antibiotic were administrated and topical corticosteroid/antibiotic combination was applied to the right eye six times a day for 10 days. Ten days after tooth extraction, clinical signs were disappeared completely.
The challenge of accurately predicting eyelid height after blepharoptosis surgery is well-known problem even in complete hands. From May, 1988 to December, 2004, authors reviewed 182 cases(240 eyes) of blepharoptosis corrected by frontalis muscle transfer or levator resection and had experienced 10 cases(15 eyelids) of early reoperation around 1 week. The period from initial operation to reoperation are between six to eight days and mean period is seven days. Initial operative procedures were frontalis muscle transfer in 3 cases(4 eyelids) and levator resection in 7 cases(11 eyelids). Follow up period ranged from 6 months to 16 years. Early adjusting surgery was performed in accordance with the preoperative and postoperative degree of ptosis of patient and considering previous operative technique. The results are evaluated according to the criteria of an ideal correction by Souther and Jordan. Seven patients have good or satisfactory results(less than 1 mm asymmetry, good in 5 cases and satisfactory in 2 cases). Three patients(5 eyelids) recorded as poor results(more than 2 mm asymmetry). Even if early or late reoperation can be effective in correcting unsatisfactory results after correction of blepharoptosis, early reoperation is better than later reoperation because early reoperation can offer a reduction in time to final result, the ease with which it is performed, potential cost savings. The experience of surgeon is also important factor for the reatment of recurred blepharoptosis

Background : Orbital roof fractures are frequently associated with a high energy impact to the craniofacial region, and displaced orbital roof fractures can cause ophthalmic and neurologic complications and occasionally require open surgical intervention. The purpose of this article was to investigate the clinical features and treatment outcomes of orbital root fractures combined with neurologic injuries after early reconstruction. Methods : Between January 2006 and December 2008, 45 patients with orbital roof fractures were admitted; among them, 37 patients were treated conservatively and 8 patients underwent early surgical intervention for orbital roof fractures. The type of injuries that caused the fractures, patient characteristics, associated fractures, ocular and neurological injuries, patient management, and treatment outcomes were investigated. Results : The patients underwent frontal craniotomy and free bone fragment removal, their orbital roofs were reconstructed with titanium micromesh, and associated fractures were repaired. The mean follow up period was 11 months. There were no postoperative neurologic sequelae. Postoperative computed tomography scans showed anatomically reconstructed orbital roofs. Two of the five patients with traumatic optic neuropathy achieved full visual acuity recovery, one patient showed decreased visual acuity, and the other two patients completely lost their vision due to traumatic optic neuropathy. Preoperative ophthalmic symptoms, such as proptosis, diplopia, upper eyelid ptosis, and enophthalmos were corrected. Conclusions : Early recognition and treatment of orbital roof fractures can reduce intracranial and ocular complications. A coronal flap with frontal craniotomy and orbital roof reconstruction using titanium mesh provides a versatile method and provides good functional and cosmetic results.
Purpose: Many researches about various surgical method for blepharoptosis have already been introduced. But researches for complications after blepharoptosis correction is relatively insufficient. So, this study was performed to recognize common complications that arised depending on the severity of blepharoptosis, levator function and surgical method. Methods: 250 patients who have underwent surgical treatment for blepharoptosis from 1987 to 2006 were employed in this study. Patients were categorized by severity of blepharoptosis, levator function and surgical method that has been used. Complications after blepharoptosis correction were analyzed. Result: Total of 64 patients had occurred complications, the specifics are as following; undercorrection 22, asymmetry 13, overcorrection 12, lagophthalmos 4, abnormal eyelid contour 4, exposure keratitis 3, ectropion 2, inclusion cyst 2, infection 1 and conjunctival prolapse 1. Among above patients, 3 patients had two kinds of complications. 21 patients was underwent secondary surgery due to complication. Conclusion: Evaluating the outcomes of the secondary surgery, the early correction was better than the late correction. The most of the complications were recovered through conservative and surgical treatments. The most of the complications (47 patients) were undercorrection, asymmetry, overcorrection and took 73.4% of the total complications. The more severe the blepharoptosis and the more poor the levator function, the rate of complications were higher. According to the operation methods, most complications were occurred in levator operation, frontalis transfer and OOM flap.
Background Although the conventional direct brow lift operation provides a simple means of managing lateral brow ptosis, the scars produced have been unacceptable. However, using the modifications proposed here, scarring showed remarkable improvement. This article reviews our experiences with the presented technique, mainly with respect to postoperative scarring. Methods Measured amounts of supra-eyebrow skin and subcutaneous fat were excised en bloc in the conventional manner under 'hyper-hydrated' local infiltration anesthesia. The lower flap and the edge of the upper flap were undermined above the muscular plane, and the orbicularis oculi muscle was directly suture-plicated and suspended upward to the distal frontalis muscle. Skin closure was performed in a basic plastic surgical manner. Results From April 2007 to April 2012, a consecutive series of 60 patients underwent surgery using the above method. The average width of the excised skin was 8 mm (range, 5-15 mm) at the apex of the eyebrow. Preoperative complaints were resolved without occurrence of significant complications. The surgical scars showed remarkable improvement and were negligible in the majority of the cases. Conclusions The direct brow lift operation combined with plication/suspension of the superior and lateral portion of the orbicularis oculi muscle provides a simple, safe, and predictable means of correcting lateral brow ptosis. The scars were acceptable to all of the patients. For proper management of the frontalis tone, upper blepharoplasty and/or repair of eyelid levator function must be considered in addition to brow lift procedures.

This study was carried out to identify the gross anatomical and radiographic characteristics of the nasolacrimal system of the Korean native goat. The results were as follows : The nasolacrimal system are composed of two lacrimal ducts, two lacrimal, canaliculus, one lacrimal sac and one nasolacrimal duct. The nasolacrimal duct was divided into proximal, middle and distal portion. The nasolacrimal duct took a straight course to be paralleled with nasal bones and opened close to the nostril on the medial surface of the alar fold. The diameter of lacrimal punctum, the length of eyelid margin to lacrimal punctum, the length of canaliculus and the diameter of lacrimal sac were 0.82~0.90mm, 1.06~1.54mm, 5.65~6.30mm and 1.77~2.06mm, respectively. The length of proximal, middle and distal nasolacrimal duct were 36.84~40.00mm, 23.53~24.31mm and 14.55~14.73mm, respectively. The diameter of the orifice of nasolacrimal duct, the length of lateral margin of nostril to orifice of nasolacrimal duct and the length of dorsum to orifice of nasolacrimal duct were 1.29~1.33mm, 12.97~12.53mm and 15.24~16.11mm. The skull index of Korean native goat was not significantly different from the length of nasolacrimal duct.
