Toxoplasma gondii is a zoonotic parasite resulting in human infections and one of the infectious pathogens leading to uveitis and retinochoroiditis. The present study was performed to assess T. gondii infection in 20 ocular patients with chronic irregular recurrent uveitis (20 aqueous humor and 20 peripheral blood samples) using PCR. All samples were analyzed by nested PCR targeting a specific B1 gene of T. gondii. The PCR-positive rate was 25% (5/20), including 5% (1) in blood samples, 25% (5) in aqueous humor samples, and 5% (1) in both sample types. A molecular screening test for T. gondii infection in ocular patients with common clinical findings of an unclear retinal margin and an inflammatory membrane over the retina, as seen by fundus examination, may be helpful for early diagnosis and treatment.

Terson syndrome was originally used to describe a vitreous hemorrhage arising from aneurysmal subrarachnoid hemorrhage. Terson syndrome can be caused by intracranial hemorrhage, subdural or epidural hematoma and severe brain injury but is extremely rare in intraventricular hemorrhage associated with moyamoya disease. A 41-year-old man presented with left visual disturbance. He had a history of intraventicular hemorrhage associated with moyamoya disease three months prior to admission. At that time he was in comatose mentality. Ophthalmologic examination at our hospital detected a vitreous hemorrhage in his left eye, with right eye remaining normal. Vitrectomy with epiretinal membrane removal was performed. After operation his left visual acuity was recovered. Careful ophthalmologic examination is mandatory in patients with hemorrhagic moyamoya disease.

Background Standard upper blepharoplasty involves removal of both the skin and a portion of the underlying orbicularis oculi muscle. The senior author had observed sluggishness of eyelid closure, lagophthalmos as well as varying degrees of eye irritation in certain patients during the early postoperative period. He postulated that these findings could be due to orbicularis muscle excision. He therefore undertook a prospective study 27 years ago comparing standard blepharoplasty on one eyelid to skin-only excision on the fellow eyelid. Methods A randomized, prospective, single-blinded study was designed using the fellow eye as an internal control. 22 patients undergoing upper blepharoplasty procedure requiring greater than 5 mm of skin resection and with no history of ophthalmologic disease, dry eye, or previous eyelid surgery were selected. Upper blepharoplasty was performed with skin-only removal on one side, and combined skin-muscle removal on the other side. Patients were evaluated until six months after surgery except for two patients who were lost to follow-up after three months. Sluggish eyelid closure, lagophthalmos, dry eye and aesthetic result were outcome measures scored by patient survey, the operating surgeon, and a blinded expert panel. Results There were comparable aesthetic outcomes in both eyelids. The incidence of sluggish eyelid closure, lagophthalmos and dry eye syndrome were significantly higher in eyelids where wide segments of muscle had been resected. Conclusions Muscle-sparing upper blepharoplasty produces similar aesthetic outcomes as conventional blepharoplasty, while significantly reducing the complications of sluggish eyelid closure, lagophthalmos and dry eye disease. The authors therefore recommend muscle-sparing upper blepharoplasty.

지난 여러 해 동안 치매에서 나타나는 안구운동기능부전에 대해 수많은 논문이 발표되었다. 안구운동검사는 뇌의 기능을 평가하는 비침습적인 검사이며, 치매와 연관된 뇌의 이상을 밝혀내는데 유용한 방법이다. 저자는 치매와 연관된 안구운동이상에 대한 지금까지의 여러 연구들을 고찰해 보았다. 알쯔하이머병에서는 신속안구운동의 잠재기가 증가하고 정확도가 감소하며 항신속안구운동의 오류가 증가 한다. 전측두엽 치매 환자에서는 반사성 신속안구운동 억제의 장애와 항신속안구운동 잠재기와 오류 증가 소견이 나타난다. 그리고 헌팅톤병에서는 수의적인 신속안구운동의 시작 지연, 느린 신속안구운동, 항신속안구운동의 오류와 잠재기 증가 소견이 나타난다. 파킨슨병 치매와 루이체 치매 환자에서는 반사성 신속안구운동과 복합성 신속안구운동 실행 장애가 보고되었다. 크로이츠펠트-야콥 병에 관한 연구는 많지 않으며, 안구운동장애는 치매 증상이 명확해진 이후인 질병의 말기에 나타나고, 이차적으로 소뇌와 전정기관을 침범하게 된다고 한다. 진행성 핵상마비에서는 느린 신속안구운동과 측정저하 신속안구운동이 수직방향주시 장애가 오기 이전에 나타나는 경우가 많다. 수의적인 눈꺼풀 운동의 기능부전도 진행성 핵상마비의 특징적인 증상이다. 결론적으로 치매 환자들은 다양한 비정상적인 안구운동장애를 나타내며 이는 피질, 피질하 기능부전과 연관되어 있다. 치매 환자의 안구운동장애에 대한 다음 단계 연구는 치매에서 나타나는 임상적인 증상이 뇌의 어떤 부위 이상 때문에 발생하는지를 좀 더 명확하게 밝히는 것이 될 것이다.

Objective : This experimental study was performed to investigate the effect of Jinpi-san on Staphylococcus aureus(S. aureus) and Staphylococcus epidermidis(S. epidermidis) that induce keratitis. Methods : Minimal inhibitory concentration(MIC) was measured by dropping to $50{\mu}l$ according to density Jinpi-san(100%, 10%, 1%, 0.1 %). Anti-bacterial potency was measured by the size of inhibition zone with change of volume. Results : 1. MIC on S. aureus in Jinpi-san was $40{\mu}l$ undiluted solution. 2. MIC on S. epidermidis in Jinpi-san was $20{\mu}l$ undiluted solution. Conclusions : These results indicate that Jinpi-san can be used to cure S. aureus, S. epidermidis that induce eye disease(keratitis). If further study is performed, the use of eye drops will be valuable and beneficial in the clinical medicines.

A new physiotherapy named Ciliary Muscle Training method and one successful case had been reported first for treatment of Posner-Schlossman Syndrome (PSS), also known as Glaucomatocyclitic Crisis. When a person observed a back and forth moving object, the ciliary muscle would involuntarily do sometimes tense and sometimes relaxant exercise which can relieve the tensive state of the ciliary muscle of patients suffering PSS disease. Through this period of continued treatment, this ciliary muscle training method can improve the health status of the ciliary muscle and finally achieve the purpose of curing PSS disease. In this successful case, the patient's feedback result was very good after receiving our suggested ciliary muscle training method as an attempt to treat PSS, ill right eye of this PSS patient showed normal appearance without any differences from the other normal eye, his vision test values of naked eye were both 4.9 under nearly 200 degrees of myopia. High intraocular pressure (IOP) was mitigated, measured IOP value was in the normal (≦ 21 mmHg) and comfortable state without PSS relapse until now. Therefore, ciliary muscle training method could be a potential clinical treatment approach to PSS disease.

With millions of people across the globe suffering from Parkinson's disease (PD), an objective, confirmatory test for the same is yet to be developed. This research aims to develop a system which can assist the doctor in objectively saying whether the patient is normal or under risk of PD. The proposed work combines the eye-hand co-ordination behaviour with the DaTscan images in order to determine the risk of this disorder. Initially, eye-hand coordination level of the patient is assessed through a hardware module. Then, the DaTscan image is analysed and used to extract certain geometrical parameters which shall indicate the presence of PD. These parameters are then finally fed into a Multi-Layer Perceptron Neural Network using Levenberg-Marquardt (LM) Back propagation training algorithm. Experimental results indicate that the proposed system exhibits an accuracy of around 93%.

Objective : Acupuncture has been used for treating eye disease for thousands of years but there are few evidence based medicine (EBM) for its use. This study is a review of Clinical trials related to the treatment of eye disease by acupuncture therapy. Methods : We referred a Pubmed site by using searching word of "eye, acupuncture" (Limits: 10 Year, Clinical Trials, Humans, English). Results : Eight journals with twelve papers were searched. Eight of these studies were randomized and ten trials of acupuncture treatments reported significant effect. On the topic of these clinical trials, five of them were about dry eyes, four about disorder of refraction, two about intraocular pressure and one about visual function. The result of clinical studies represented the significant cure rate. Conclusion : We found that RCTs about the acupucnture for eye diseases were more and more published. But their average impact factor was 2.16 and average modified Jadad score was 3.89, so there needs more qualifying studies.

Information about retinal blood vessels can be used in grading disease severity or as part of the process of automated diagnosis of diseases with ocular menifestations. In this paper, we address the problem of detecting retinal blood vessels and optic disk (papilla) in eye-fundus images. We introduce an algorithm for feature extraction based on Fuzzy Clustering algorithm (fuzzy c-means). A method of finding the optic disk (papilla) is proposed in the eye-fundus images. Additionally, the inrormations such as position and area of the optic disk are extracted. The results are compared to those obtained from other methods. The automatic detection of retinal blood vessels and optic disk in the eye-rundus images could help physicians in diagnosing ocular diseases.
