  • Ocular lesions induced in 40 specific-pathogen-free Marek's disease (MD) resistant chicks by inoculation at 1 day of age with very virulent strain of Marek's disease virus (WV) were pathologically examined. Grossly,24/40 (60%) chicks had white gel-like materials in the vitreous body, whereas thickening and discoloration of iris (gray eye) were not observed. Microscopically, characteristic ocular MD lesions were observed in choroid (27/40), ciliary (30/40) and iris (23/40) in which small focal inflammatory to diffuse neoplastic Iymphoid cells were infiltrated. Five out of 40 MDV-inoculated birds revealed necrotizing Iymphomas in choroid. These lesions consisted of necrotic and degenerating Iymphoblasts accompanied by intranuclear inclusion body. There was retinal atrophy and necrosis with inclusion body detected in necrotic ganglion, inner or outer nuclear and infiltrated Iymphoblast cells. Conjunctiva showed lymphoid cell infiltration in 29/40 chicks inoculated with MDV, Vitreous body exhibited mild to severe exudation of eosinophilic proteinaceous material in 24/40 chicks. These lesions were associated with Iymphoid cell infutration, edema and fibrosis of choroid. Pecten (7/40) and optic nerve (13/40) were infiltrated usually mildly with Iymphoid cells. From these results, very virulent strain, Md/5 of MDV caused high incidence of ocular lesions in MD resistant chicks. In addition, Md/5 induced exudation of proteinaceous material into the vitreous body and fibrosis of choroid. Necrotizing ocular Iymphoma lesions in choroid is the first report in the MD literature.

  • Objectives : The purpose of this study is to analyze effectiveness of herbal medicine treatment on Dry Eye Syndrome. Methods : We analyze medical records of 114 patients who visited Indara oriental medical clinic for dry eye syndrome. Patients were treated with acupuncture and Inmok-tang, and the ocular surface disease index was evaluated before and after treatment. Results : Analysis of 114 medical records showed a significant decrease in the pre-treatment and post-treatment ocular surface disease index, and a statistically significant positive correlation between the duration of Inmok-tang administration and the change in the ocular surface disease index. Conclusions : Herbal medicine treatment with Inmok-tang reduces the Ocular Surface Disease Index, an indicator of subjective symptoms of dry eye syndrome.

  • Objectives : The purpose of this study was to identify the effects of self-acupressure on the visual health of college students. Methods : A nonequivalent control group pretest-posttest design was used. Participants were determined by OSDI(ocular surface disease index) and the Schirmer test, they were assigned to an experimental group of 22 and control group of 22. The experimental group participated in self-acupressure, which were practiced 2 times a day, 5 days a week for 4 weeks. Results : Scores of ocular surface disease index, Schirmer test and ocular fatigue were significantly better in the experimental group after the intervention compared to the control group. Conclusions : The result indicate that self-acupressure is an effective nursing intervention for improving the dry eye syndrome and decreasing ocular fatigue in college students.

  • 목적: 울산지역의 안질환 발생환자에 있어서 연령별에 따른 특정질환을 알아보고자 하였다. 방법: 울산지역의 안과병원을 내원한 환자 300명을 대상으로 환자의 성별, 초진당시 연령, 과거력, 진단명 등을 기준으로 분석하였다. 결과: 10대의 경우에는 각막염이 가장 많은 비중을 차지하였고, 20대는 건조증과 각막염, 30대는 콩다래끼와 결막염, 40~50대의 경우에는 결막염, 60대의 경우에는 결막염과 백내장이 많은 비중을 차지하는 것으로 나타났다. 결론: 주요 안질환 원인으로는 10~20대는 콘택트렌즈의 부적절한 착용과 스마트폰과 컴퓨터 매체 등의 장기간 사용, 30~50대는 알러지성 결막염이나 화학물질 등으로 인한 반응 등 여러 가지 요인으로 분석되는데 특히, 공업지역의 특성상 타지역 보다 결막염의 발생빈도가 더 높게 나타났으며, 50대 중반부터 60대 이상은 일종의 노화현상이 원인인 것으로 분석되어진다. 따라서, 본 연구결과는 울산지역에서 발생될 수 있는 안질환 예방을 위한 기초 자료로 활용될 수 있을 것으로 여겨진다.

  • Ocular injury is one of the commonest causes of eye diseases, but its patterns and incidences are variable according to the environment. Blunt Ocular Trauma is one of causes of ocular injury. Visual disturbance by Blunt Ocular Trauma is rarely reported and we do not know the exact convalescence and healing method of that. We treated a patient suffered from visual disturbance by blunt ocular trauma with herbal medicine, acupuncture, cupping treatment. We diagnosed as Blood stasis and noxious water disease. We report a case of visual disturbance by blunt ocular trauma after treatments, we observed the improvement. Based on this study, it is considered that oriental medical treatment can be applied to the management of visual disturbance.

  • Ocular toxoplasmosis is a disease caused by the infection with Toxoplasma gondii through congenital or acquired routes. Once the parasite reaches the retina, it proliferates within host cells followed by rupture of the host cells and invasion into neighboring cells to make primary lesions. Sometimes the restricted parasite by the host immunity in the first scar is activated to infect another lesion nearby the scar. Blurred vision is the main complaint of ocular toxoplasmic patients and can be diagnosed by detection of antibodies or parasite DNA. Ocular toxoplasmosis needs therapy with several combinations of drugs to eliminate the parasite and accompanying inflammation; if not treated it sometimes leads to loss of vision. We describe here clinical features and currently available chemotherapy of ocular toxoplasmosis.

  • Angiostrongyliasis, caused by Angiostrongylus cantonensis infection, is a food-borne parasitic disease. Its larvae evoke eosinophilic inflammation in the central nervous system, but can also cause pathological changes in the eyes. Among ocular angiostrongyliasis cases, the incidence of optic neuritis is low and only few sporadic reports exist. Some patients with optic neuritis developed obvious hypopsia or even vision loss, which would seriously influence the quality of life of patients. Prompt treatment of optic neuritis caused by A. cantonensis is the key factor for minimizing the incidence of serious complications of this disease. In this review, we first provide a comprehensive overview of ocular angiostrongyliasis, and then focus on the clinical features of optic neuritis caused by A. cantonensis.

  • 질병과 관련한 연구 중 가장 중요한 것은 질병이 발생치 알도록 하기 위해 치료보다는 예방과 보건 그리고 약품보다는 식품을 더 중요시해야 한다는 것이다. 따라서 일단 환자를 접할시 가장 중요한 것은 질환의 유무 그리고 만약 질환이 있다면 어떤 질환인지를 정확히 진단해 내는 것이 가장 중요하고 그 후에 용약(用藥) 과정을 거치게 된다. 본 논문에서는 한방에 있어 4대 질환 진단 방법중 가장 중요한 망진(望診)에 대해 기술하고자 한다. 망진은 관형(觀形)과 찰색(察色)이 주된 방법인데 지금까지는 이를 모두 의사의 직관에 의지 하였 왔던 것이 현 실정이었다. 이를 위해 본 연구에서는 의사에게 망진에 필요한 기초 자료를 자동으로 제공해 주는 시스템을 개발하고자 한다. 이때 시스템 개발시 개발 단계상 첫 번째 개발 단계이며 가장 중요한 작업은 관형이나 찰색에 상관없이 우선적으로 얼굴 영역을 자동으로 추출해 내는 작업이 수행되어야 한다. 또한 추출된 얼굴 영역에서 정면 얼굴인 경우는 중요한 얼굴내 요소인 눈, 눈썹, 코, 입등의 영역을 추출해 주고, 측면 얼굴의 경우는 코와 귀를 추출해 내는 작업이 전체 시스템 구축시 두 번째 작업 단계가 된다. 따라서 본 논문에서는 관형과 찰색을 위한 전체 시스템 개발 작업중 첫 번째와 두 번째 단계 작업인 정면 얼굴의 얼굴 영역 추출 방법, 그리고 추출된 정면얼굴 영역에서 눈, 눈썹, 코, 입등의 영역을 추출해 주는 방법에 대해 제안하고자 한다. 또한 제안한 방법의 유용성을 확인하기 위해 20명을 대상으로 실험을 수행한 결과 정면 얼굴의 영역 추출은 $100\%$ 성공하였다. 그리고 눈, 눈썹, 코, 입등과 같은 정면 얼굴내 주요 특징 영역 추출도 $100\%$ 성공하였으나 머리카락과 눈썹이 붙어 있는 경우에는 해당 눈썹 영역을 추출하지 못하는 결과도 있었다. 이는 차후 형태학적 연산등을 사용하여 추출해야 할 으로 사료된다.

  • Objectives : The aim of this study was to compare the effects of 12 acupuncture treatments versus 24 acupuncture treatments for patients with dry eye syndrome. Methods : We have assessed the symptom score, number of dry eye symptoms, and ocular surface disease index(OSDI) scores before and after the acupuncture treatments. The group A received 12 acupuncture treatments, and the group B received 24 acupuncture treatments. To evaluate the efficacy of acupuncture treatments the before and after scores of both groups were compared. Results : After treatment, symptom score, number of dry eye symptoms, and ocular surface disease index(OSDI) were significantly decreased in each group (p<0.001). The symptom score has shown a greater decrease in group B than group A, but no significant differences were seen in the numbers of existing symptoms and ocular surface disease index(OSDI) scores between the two groups. Conclusions : Acupuncture is an effective way to relieve the symptoms of dry eye syndrome. The more number of acupuncture treatments may be correlated with better outcomes in the means of symptom score.
