Eye socket contracture is a well-known late complication of enucleation surgery, and the additional insult of radiotherapy at an early age causes even further fibrosis and scarring of the socket. Management of the contracted socket is challenging, and several methods have been proposed. We report a case of eye socket contracture after enucleation and radiotherapy in which multiple reconstructive procedures failed. The recurrent contracture caused difficulty in housing and retaining the eye prosthesis. We reconstructed the lower eyelid with a facial artery myomucosal flap and nasolabial flap, and the upper eyelid with a Fricke flap following reconstruction of the orbital rims (supraorbital and infraorbital rims with a calvarial bone graft, and further augmentation of the infraorbital rim with a rib bone graft). Cosmesis post-reconstruction was acceptable and the prosthesis was retained very well.

Lack of sleep time increases risks of fatigue, hypomnesis, decreased emotional stability, indigestion, and dementia. The risks can be reduced by providing eyelid-warming, inducing sleep and improving sleep quality. However, effective warming temperature to an person varies depending on physical condition and the individual. The various types of frequencies can be identified in brain wave from a person and amount of frequencies is also changed continuously before and after sleep. Therefore we can identify the user's sleep stage with brain wave, namely EEG. Effective sleep induction is possible if warming temperature to a person is controlled based on EEG. In this paper, we propose customized warming control techniques based on EEG for a efficient and effective sleep induction. As an experiment, sleep induction effects of standard sleep mask and customized temperature control techniques sleep mask are compared. EEG data and warming temperature were measured in 100 experiments. At customized warming control techniques, experiments showed that the ratio of alpha and theta waves increased by 3.21%p and the time to sleep decreased by 85 seconds. It will contribute to effective sleep induction and performance verification methods in customized sleep mask systems.

A 76-year-old woman, initially thought to have a simple abscess on her right upper eyelid, presented to our department of plastic and reconstructive surgery. Enhanced three-dimensional facial computed tomography (CT) revealed an abscess on the right upper lid, with a pyomucocele present in the right frontal sinus, accompanied by bone erosion in the superior wall of the right orbit. Based on the results of the CT scan, we diagnosed an atypical Pott's puffy tumor (PPT) with an abscess on the upper lid originating from the frontal sinusitis. First, surgical incision and drainage were performed in our department, and a percutaneous vacuum drain was placed. To provide a more definitive treatment, endoscopic sinus surgery (ESS) was subsequently performed by otorhinolaryngologists. The patient was discharged without any complications 5 days after ESS. At a 1-year follow-up, no recurrence or notable neurological symptoms were observed. In the case we observed, the patient presented with an upper eyelid abscess and cellulitis, indicating possible orbital involvement. For such patients, a CT scan is necessary. Given the possibility of PPT, it is critical to perform a comprehensive differential diagnosis rather than defaulting to a straightforward approach involving abscess treatment.

One-year-old male Cocker Spaniel dog was referred for the third eyelid enlargement and inflammation in the left eye (OS). It gradually swelled for 2 weeks after the cherry eye repair by conjunctival mucosa pocket procedure at a private animal clinic. Routine ophthalmic examinations including neuro-ophthalmic examination, Schirmer tear test, intraocular pressure and corneal fluorescein staining were all normal. No lesions were found on slit lamp biomicroscopy and indirect ophthalmoscopy except for third eyelid swelling in the OS. Ultrasonography revealed cystic structure within the OS nictitating membrane. Fluid from the cyst was aspirated and there were no microorganisms or neoplastic changes. Surgical intervention was performed under general anesthesia. On the day of the surgery, there was a deep corneal ulcer in the OS, which had not existed before. Ventral palpebral surface of the third eyelid was incised horizontally to the shaft of the T-shaped hyaline cartilage. And then, a full thickness of the cystic wall was incised and marsupialized. Additionally, a direct suture was performed on the ulcerated cornea. Topical and systemic antibiotics and anti-inflammatory drugs were prescribed. One month after the surgery, the third eyelid swelling and the discharge were improved. Marsupialization of the nictitating membrane cyst relieved the swelling of the third eyelid and inflammation. It could be a simple but effective surgical intervention for the cystic complication of conjunctival mucosa pocket procedure in dogs.

본 방법을 통해 수술할 경우 몇 가지 장점이 있다. Y needle의 경우 5mm간격으로 고안되어 있어 3부위에서 일정량의 조직결찰이 가능하고 고안에 따라 여러 가지 간격으로 만들어 질 수 있어 환자의 상태에 따라 적용가능하다. 또한 피부부위에서 결막으로 들어가는 부위가 수직이어서 원하는바 정확한 이중검 위치를 만들어 줄 수 있다. 초심자가 시행하더라도 관통부위를 eyelash 경계와 비교적 평행하게 만들어 줄 수 있다. Needle의 삽입이 2개가 한꺼번에 삽입되므로 환자가 느끼는 통증이 감소되며 술자의 편의도도 증가하리라 생각된다. 부분절개법을 사용하여 잉여지방 및 조직을 제거하였고 매몰하여 흉터와 부작용을 최소화하였고 회복기간과 수술시간을 감소시킬 수 있었다. 본 방법은 모든 경우의 이중검수술에 이용될 수는 없겠으나 고찰에서 기술한 비절개식이나 부분절개식 이중검수술의 적응증에 해당되는 경우에 이용할 경우 아주 간단하고 임상적으로 표준화 될수 있는 방법으로 응용될 수 있을 것으로 사료되어 문헌고찰과 함께 보고하는 바이다.

Management of eyelid cancers is based on surgery and/or radiotherapy (RT). The treatment objective is to control tumors with acceptable functional and esthetic outcomes. The aim of this study was to evaluate the results of radiation therapy in management of epithelial eyelid cancers, reviewing retrospectively the clinical records of patients treated in our institution from January 1989 to December 2013. We focused on clinical and histological features, treatment characteristics, tolerance and disease control. One hundred and eight patients (62 men and 46 women) were enrolled, with a mean age of 61 years [ranges 15-87]. The most frequent tumor location was the inner canthus (42.6%). Median tumor size was 21 mm [ranges 4-70]. Histological type was basal cell carcinoma in 88 cases (81.5%), squamous cell carcinoma in 16 (14.8%) and sebaceous carcinoma in 4 (3.7%). Radiation therapy was exclusive in 67 cases (62%) and post-operative for positive or close margins in the remaining cases. Kilovoltage external beam radiotherapy (KVRT) was used in 63 patients (58.3%) and low-dose-rate interstitial brachytherapy in 37 (34.3%). Eight (7.4%) were treated with cobalt or with a combination of KVRT-cobalt, KVRT-electron beams, KVRT-brachytherapy or cobalt-electron beams. The total delivered radiation doses were 70 Gy (2 Gy/fraction) in 62 patients (57.4%), 66 Gy (2 Gy/fraction) in 37 (34.3%) and 61.2 Gy (3.4Gy/fraction) in 9 (8.3%). After a median follow-up of 64 months, we noted 10 cases of local recurrences(9.2%): 7 after exclusive and 3 after post-operative RT. No local recurrence occurred in patients treated with brachytherapy. Actuarial 5-year local recurrence-free rate, disease-free survival and overall survival were respectively 90%, 90% and 97%. T-stage was found to be a significant factor for recurrence (p=0.047). All acute radiation-related reactions were scored grade I or II. Delayed effects were eye watering in 24 cases (22.2%), eye dryness in 19 (17.6%), unilateral cataract in 7 (6.4%) and ectropion in 4 (3.7%). Radiation therapy and especially brachytherapy is an efficient treatment of eyelid cancers, allowing eye conservation and functional preservation with good local control rates and acceptable toxicity.

눈꺼풀에 발생한 종양의 치료를 위해서는 종종 고에너지 전자선이 이용되며, 이 경우 환자의 시력 보호를 위해 금속차폐체를 눈꺼풀과 안구 사이에 삽입하고 방사선 치료를 시행한다. 차폐체에 접한 눈꺼풀 안쪽의 방사선량 확인을 위해서는 매우 작은 측정도구가 필요하며, 굽은 경계면의 특성상 유연한 측정도구가 바람직한데, radiochromic 필름 도시메트리는 이 목적에 매우 적합하다. 작으면서도 휘어진 경계면을 따라서 선량을 측정하기 위해, 눈꺼풀 팬텀과 차폐체 사이에 3-mm 폭의 EBT2 필름 띠를 삽입하고, 6MeV의 전자선을 조사 후, 선량분포를 얻었다. 금속차폐체와 동일한 크기로 아크릴 재질의 차폐체를 제작하여, 금속인공영상물이 없는 CT 영상을 얻은 후, 이를 이용하여 몬테칼로 전산모사를 수행하였다. 전산모사에서는 실제 안구차폐체의 재질을 따라 텅스텐, 알루미늄 및 스테인레스 스틸 등의 물질 정보를 이용하였다. 이렇게 얻은 전산모사 결과는 필름 측정과 2.1% 내에서 일치하였다. 밀리미터 크기 정도로 작고 또한 휘어진 영역에서 radiochromic 필름 도시메트리는 취급도 용이할 뿐만 아니라 만족스런 정확도를 보여주고 있다.

Tarsorrhaphy is widely used to protect the cornea, reduce evaporation of tears, and facilitate reepithelialization of the ocular surface. However, a dilemma ensues in patients when frequent neurological evaluations and postoperative examinations are needed. The modified temporary tarsorrhaphy in this study was simple to perform, provided stable eyelid closure, and could be opened and closed as needed. It could be easily reversed with minimal complications of the eyelid and it allowed the surgeon to control traction of the bolsters in all of 45 dogs with corneal epithelial defects. Also, The globe could be examined without further anesthesia, sutures, and pain at any time after surgery. It was concluded that this modified method might be effective for evaluation of the corneal healing process and useful for ocular surface reconstruction clinically.

Oculomotor nerve palsy is a disorder which causes eyeball movement trouble, dipleopia, dizziness and eyelid ptosis. It is caused by aneurysm, mass, truma, intracranial hypertension, diabetes mellitus, infection and so on. But sometimes we can't establish the cause. We report a case of oculomotor nerve palsy associated with spleen energy(脾氣). We treated a patient with herb medicine and acupuncture. This study suggests that oriental medicine theraphy has a good effect on the oculomotor nerve palsy.
