  • Vogt-Koyanagi-Harada(VKH) Disease is a bilateral granulomatous uveitis often associated with exudative retinal detachment and extraocular manifestations, such as pleocytosis in the cerebrospinal fluid and, in some case, vitiligo, poliosis, alopecia, and dysacusis. There has been no previous report for the disease in the field of Korean traditional medicine. The case was treated with conventional medical intervention and Korean traditional treatment including acupuncture and herbal medicine. The case was discharged with improvement in fundus photography and optical coherence tomography. The authors report the case to suggest that Korean medical approach combined with conventional treatment can be helpful for the disease.

  • 서울에서 개의 안과질환에 대한 역학적인 특징에 대해 2009년 1월부터 2013년 12월까지우성동물메디칼센터에 안과질환으로 내원한 초진환자들의 자료를 분석하였다. 총 1253두의 안과환자들이 초진 내원하였으며, 평균나이는 7.93년령 (SD, 4.06)이었다. 환자중에 Shih Tzu (29.4%)가 가장 많았으며, Maltese, Yorkshire Terrier, Cocker Spaniel, toy Poodle (P < 0.01)이 뒤를 따랐다. 눈에서 질병이 호발하는 곳은 수정체 관련 질환이 가장 많았으며 (28.3%), 안검질환, 망막질환, 비루관질환, 포도막질환, 유리체질환, 시신경계 질환이 그 뒤를 따랐다(P < 0.01). 수정체, 안검, 망막, 비루관, 포도막, 유리체, 시신경계 질환들은 주로 양측성 질환(P < 0.01)으로 발생하는 경향을 보였다. Shih Tzu에서는 각막질환이 가장 많이 발생하였으며, 수정체, 안검, 망막, 녹내장 질환이 그 뒤를 따랐다. Maltese에서는 수정체, 안검, 망막, 각막질환의 순으로 질병이 발생했다. Yorkshire Terrier, Cocker Spaniel, 그리고 toy Poodle 종은 수정체 질환이 가장 많았다(P < 0.01). 안과질환으로 병원에 내원하는 주된 환자들은 Shih Tzu, Maltese, Yorkshire Terrier등과 같은 소형견들이었고, 대부분 수정체 질환과 같은 품종소인이 있는 질환이 대부분이었다.

  • Von Hippel-Lindau (VHL) disease is an autosomal dominant hereditary disorder caused by a germline mutation of the VHL gene. It is a multi-systemic disorder that is predisposed to benign or malignant tumors of visceral organs such as hemangioblastoma of the central nervous system, renal cell carcinoma, retinal angioma and pheochromocytoma. We report herein a case of VHL disease that initially manifested with aortic valve insufficiency.

  • 전 세계적인 인구 고령화 현상으로, 녹내장, 백내장, 황반변성과 같은 실명을 초래할 수 있는 주요 안질환의 발병률이 상승하고 있다. 이에 안과 분야에서는 실명률을 줄이기 위해 예방이 어려운 질환의 진단에 관심이 집중되고 있다. 본 연구는 기존보다 적은 양의 데이터를 활용하여 안저 사진 내의 안질환을 정확하게 진단하는 딥러닝 방안을 제안한다. 이를 위해 적은 데이터로도 효과적인 학습이 가능한 Convolutional Neural Network (CNN) 모델을 선정하여 다양한 안질환 환자의 Conventional Fundus Image (CFI)를 분류 한다. 선정된 CNN 모델들은 Accuracy, Precision, Recall, F1-score에서 우수한 성능을 기록함으로써 CFI 내 안질환의 정확한 분류에 탁월한 성능을 보였다. 이러한 접근법은 안과 전문의들의 수작업 분석을 줄이고, 진료 시간을 단축하며, 리소스가 제한된 환경에서도 일관성 있는 진단 결과를 제공함으로써 의료 현장에 효율적이고 정확한 진단의 보조 도구로 기여할 수 있다.

  • 망막색소상피(retinal pigment epithelium, RPE)는 시기능을 유지하는데 중요한 역할을 하여 RPE의 퇴화는 여러 망막변성질병을 유발한다. 현재 이에 대한 효과적인 치료법이 부족하여 세포 이식에 적합한 지지체를 제작하기 위해, 생분해성 고분자인 PLGA와 항염증, 항산화 작용 등의 기능이 있는 헤스페리딘을 이용하여 하이브리드 필름을 제조하였다. ARPE-19를 파종한 후, MTT 분석법을 이용하여 세포 증식률을 확인하고, 세포의 부착 및 세포 형태를 SEM을 통하여 확인하였다. 또한 RPE 세포의 특이적 유전자 발현정도를 확인하기 위하여 RT-PCR을 수행하였고, RPE65의 발현을 확인하기 위해 AEC 면역화학적 염색을 실시하였다. 그 결과, 헤스페리딘/PLGA 필름은 PLGA보다 RPE 세포의 부착, 증식 및 표현형 유지가 우수함을 확인하였고, 이를 통해 헤스페리딘/PLGA 필름의 망막재생을 위한 조직공학적 담체로써 응용 가능성을 확인할 수 있었다.

  • 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.

  • Background: Endogenous uveitis is a chronic inflammatory eye disease of human, which frequently leads to blindness. Experimental autoimmune uveoretinitis (EAU) is an animal disease model of human endogenous uveitis and can be induced in susceptible animals by immunization with retinal antigens. EAU resembles the key immunological characteristics of human disease in that both are $CD4^+$ T-cell mediated diseases. Dendritic cells (DCs) are specialized antigen-presenting cells that are uniquely capable of activating naive T cells. Regulation of immune responses through modulation of DCs has thus been tried extensively. Recently our group reported that donor strain-derived immature DC pretreatment successfully controlled the adverse immune response during allogeneic transplantation. Methods: EAU was induced by immunization with human interphotoreceptor retinoid-binding protein (IRBP) $peptide_{1-20}$. Dendritic cells were differentiated from bone marrow in the presence of recombinant GM-CSF. Results: In this study, we used paraformaldehyde-fixed bone marrow-derived DCs to maintain them in an immature state. Pretreatment with fixed immature DCs, but not fixed mature DCs, ameliorated the disease progression of EAU by inhibiting uveitogenic $CD4^+$ T cell activation and differentiation. Conclusion: Application of iBMDC prepared according to the protocol of this study would provide an important treatment modality for the autoimmune diseases and transplantation rejection.
