Objective : Cosmetic surgery, as a psychosocial intervention, is unique in that its foundation rests solely on the individual motivations, internal or external, of the patient We investigated the ego-identity in women who seek double eyelid operation, to understand one aspect of internal motivation for cosmetic surgery. Methods : Subjects of this study were 47 young women, visited to plastic surgery clinics in Kwangju from June 1993 to October 1993, and 58 women who did not want double eyelid operation were chosen as controls. Each subject's ego-identity was scored using Dignan's ego-identity scale. Results : The total and stability subscale's scores of ego-identity of double eyelid operation group were significantly lower than those of control group. Conclusion : More psychosocial research on the ego-identify of patients seeking double eyelid operation is required to understand the psychological motives for requesting surgery.

Lower eyelid blepharoplasty is a popular facial rejuvenation surgery that restores the infraorbital region. The procedure is performed by removing excessive fatty tissues, muscles, and other unnecessary structures. The structure of the eyelid differs from person to person and is quite complex; therefore, numerous side effects are expected. Common lower eyelid blepharoplasty complications are asymmetrical faces, retrobulbar hemorrhage, blurred vision, and ectropion. This paper reports a case of a prominent periorbital vein after lower eyelid blepharoplasty. The prominent periorbital vein after surgery is a rare side effect that has not been reported to the best of the author's knowledge. This case was treated with a long-pulse 1,064-nm neodymium:yttrium-aluminum-garnet laser.

Purpose: Perceiving the experience that $MRD_1$ is increased after small-incision double-eyelid operation, it has been statistically verified the improvement of $MRD_1$ retrospectively. Therefore, we suggest new interpretation for Korean-specific small eye and more definite classification for ptosis. Methods: In operation, we made 3 small incisions according to the line designed on upper eyelid and removed some soft tissues including connective tissues. Then, figure-of-8 continuous buried ligation was performed through the incision windows. This study is a retrospective study, measures $MRD_1$ changes and excursion distance change of eyelid margine and eyebrow using pre-and post-operative photos of 14 patients. Results: Postoperative photos were taken on the 4th day and all of 14 patients had an improvement in $MRD_1$ statistically. The excursion distance of upper eyelid was improved in half of patients, though not in the range of statistical verification. It was statistically confirmed that the movement of eyebrow was reduced after operation. Conclusion: It is thought that $MRD_1$ improvement without any operation on levator complex means that soft tissue including connective tissue eliminated in operation restricts the movement of upper eyelid. It is defined such factors as burden factors and such phenomenon as burdened eyelid. It is thougt that Korean's small eye is mainly burdened eyelid and cosmetic improvement may be obtaind even by removing such burden factors.

Background This study evaluated the outcomes of a new modified Wies technique for patients with involutional lower eyelid entropion without horizontal eyelid laxity. Methods This case series retrospectively analyzed consecutive patients with entropion who underwent surgery between January 2014 and March 2019 by the same experienced surgeon. Horizontal eyelid laxity, lower eyelid retractor function, and orbicularis muscle overriding were recorded before and after surgery. The recurrence rate and complications were also evaluated. This technique consisted of modified everting sutures combined with reattachment of the lower eyelid retractors to the inferior tarsal plate. Results This new technique was performed on 28 eyes in 25 patients (mean age, 71.0±8.0 years; range, 56-87 years). Nine patients (36%) were women and 16 (64%) were men. Lower lid entropion was present in the right eye in 14 patients (56%), the left eye in eight patients (32%), and both eyes in three patients (12%). The mean follow-up period was 27.3±12.4 months (range, 6-60 months). No intraoperative complications were observed. All patients' symptoms were alleviated. One patient (3.6%) had recurrence after 2 years (success rate, 96.4%). The remaining 27 eyes maintained a satisfactory and comfortable eyelid position. No patients had problems with scarring. Conclusions The approach described herein proved to be safe and feasible in eyes with involutional lower eyelid entropion without horizontal eyelid laxity. These advantages of this procedure include the lack of a conjunctival scar, punctal eversion, and lateral canthal angle deformation. A low recurrence rate and a long interval to recurrence were also observed.

A 9-year-old spayed female Shih-Tzu was presented with a mass on the upper eyelid of the right eye (OD). The eyelid mass continued to enlarge along the eyelid margin and the eyelid skin. Throughout the follow-up examinations, the mass did not affect the palpebral conjunctiva OD. Until 9 months since the mass was first identified, the dog did not show any clinical signs related to the mass. However, after 11 months, the owner complained of the dog's discomfort on OD and decided on surgical excision of the mass. There were no abnormalities in the complete blood count and serum chemistry profiles. The pentagonal resection was performed to completely remove the mass in the eyelid. There were no suspicious findings of metastasis on whole-body computed tomography scan immediately before the surgery. On histopathology and immunohistochemistry for multiple myeloma oncogene-1, the eyelid mass was diagnosed as extramedullary plasmacytoma (EMP). Surgical margin of the mass was clearly cut. No recurrence was observed during the 5-month follow-up. EMPs on the eyelid have rarely been reported in dogs. Although EMP is a benign tumor, the mass showed invasive growth and grew toward the skin rather than the palpebral conjunctiva. No recurrence occurred when surgically removed with clean margins.

The reconstruction of total lower eyelid defects is challenging to plastic surgeons due to the complicated anatomical structure of the eyelid. In addition, in the setting of cancer excision, the resection is deep, which requires some volume augmentation. However, in some cases, free tissue transfer is not applicable. We report a case of using a temporoparietal fascia flap (TPFF) for reconstructing a total lower eyelid defect. A large erythematous mass in an 83-year-old woman was diagnosed as squamous cell carcinoma by biopsy. After wide excision, the defect size was about 8×6 cm. The lower eyelid structures including the tarsus were removed. The TPFF including the superficial temporal artery was elevated and inset to the defect area. After the flap inset, a split-thickness skin graft with an acellular dermal matrix was performed on the fascial flap. There were no wound problems such as infection, dehiscence, or necrosis. After the patient's discharge, partial skin graft loss and ectropion occurred. The complications resolved spontaneously during the postoperative period. We report a case of reconstructing a lower eyelid defect using a TPFF. A TPFF can be applied to patients with large defects for whom free tissue transfer surgery is not appropriate as in this case.

홍채 인식은 홍채 패턴 정보를 이용하여 사람의 신원을 확인하는 생체 인식 기술이다. 일반적인 홍채 인식 시스템에서 취득된 홍채 영상에는 홍채 패턴 정보를 가리는 눈꺼풀이 포함된다. 이러한 눈꺼풀은 홍채 인식의 성능을 저하시키는 요소이다. 따라서 본 논문에서는 홍채인식의 정확성을 향상시키기 위해 눈꺼풀 검출 알고리즘을 제안한다. 본 연구는 기존의 방법에 비해 다음과 같은 세 가지 차별성과 장점을 가지고 있다. 첫 번째, 눈꺼풀 검출에 문제가 되는 속눈썹과 조명 반사광(specular reflection)을 기존의 방법에 의해 검출한 후에, 선형 보간법(interpolation)을 이용하여 제거하는 방법을 제안함으로써 눈꺼풀 추출의 정확도를 향상하였다. 두 번째, 기존의 알고리즘은 눈꺼풀 후보점을 추출하기 위해 홍채의 넓은 부분을 탐색하므로 영상잡음이나 홍채 패턴 등에 의해 눈꺼풀을 잘못 추출하는 경우가 많았다. 이러한 문제를 해결하기 위하여 본 논문에서는 검출된 홍채의 외곽경계 정보에 의해 초기 눈꺼풀 탐색 영역을 결정하고, 마스크 기법을 이용하여 눈꺼풀 후보점들을 추출함으로써 눈꺼풀 추출 에러를 감소시켰다. 세 번째, 기존의 알고리즘들은 포물선 방정식에 의해 눈꺼풀 영역을 검출하지만, 사용자의 눈의 회전을 고려하지 않았기 때문에 많은 에러가 발생되었다. 따라서 제안하는 알고리즘은 눈의 회전을 고려한 회전된 포물선 방정식을 이용한 허프 변환(Hough transform)을 통해 눈꺼풀을 검출함으로써 이러한 에러 발생을 감소시켰다. CASIA 데이터베이스의 홍채 영상을 사용하여 제안하는 눈꺼풀 검출 알고리즘을 실험한 결과, 위 눈꺼풀의 검출 정확도는 90.82%, 아래 눈꺼풀의 검출 정확도는 96.47%였다.

Purpose: Double - eyelid operation is one of the most common cosmetic operations among Korean patients. In such operations, however, the complexity of and individual differences in the patients' anatomical structures may cause various complications, such as asymmetry, retraction of the eyelid, and the occurrence of a high fold. A high fold occurs frequently, and its correction is not very simple. Many methods have been developed to correct it, and among these, the operation involving the excision of the skin between the previous double - eyelid line and the new double - eyelid line is usually selected by plastic surgeons. In many cases, however, patients have insufficient eyelid skins for this operation. In this study, the authors introduce an operation procedure for high - fold correction that does not involve skin excision Methods: From June 2005 to June 2009, 246 cases were treated with this procedure. After the incision of the new double - eyelid line, dissection was done between the previous scar tissue and the levator aponeurosis. Then the orbital septum, orbital fat or the retro - orbicularis oculi fat was slid down and sutured with a tarsal plate. Such sutures were repeated at four to five points, including the lateral and medial limbus, to prevent the reattachment of the previous scar and to create a new double - eyelid line at the end of the orbital septum. Results: Most of the high - fold patients were satisfied with the procedure described above. Their previous scar was hidden under the new double - eyelid line after the operation. In the six cases, the scar was visible in the patients who had a very high and deep inner line. As such, scar revision was undertaken three months after the operation. It is known that scar revision is also required after an operation involving skin excision in the case of a very high inner - eyelid line. Conclusion: This method is an appropriative procedure for high - fold correction for patients who have insufficient upper - eyelid skin.
