Purpose: To compare the choroidal thickness in central serous chorioretiopathy (CSC) patients and normal controls using spectral domain optical coherence tomography (SD-OCT). Methods: The authors compared the choroidal thickness in eyes with CSC, fellow eyes and in normal eyes. In addition, the authors attempted to determine any correlation between choroidal thickness and other factors such as age, height of serous retinal detachment, and spherical equivalent. Choroidal thickness was measured using a perpendicular line from the outer margin of the subfoveal retinal pigment epithelium to the inner surface of the sclera. Results: Twenty-five eyes of 25 CSC patients, 17 fellow eyes and 29 age-matched normal eyes were examined and categorized as group 1, group 2 and group 3, respectively. Subfoveal choroidal thickness was 370.64 ± 58.06 μm in group 1, 301.85 ± 47.83 μm in group 2, and 261.84 ± 48.22 μm in group 3. The choroidal thickness in group 1 was significantly greater than those in group 2 and group 3, and the choroidal thickness in group 2 was significantly greater than that in group 3 (p = 0.001, p < 0.001, p = 0.004, respectively), where the choroidal thickness showed a negative correlation with age (p = 0.015). Conclusions: The choroidal thickness was greater in eyes with CSC and in their fellow eyes compared to that in normal eyes. The results suggest that CSC may be caused by choroidal vascular hyperpermeability and increased hydrostatic pressure in the choroid. J Korean Ophthalmol Soc 2012;53(1):87-93

Purpose: To analyze the long-term results of photodynamic therapy (PDT) for exudative age-related macular degeneration (AMD). Methods: The clinical data of patients treated with photodynamic therapy for exudative age-related macular degeneration between April 2000 and December 2000 were analyzed. Patients were followed-up for at least 10 years after PDT. Results: Twenty-nine eyes of 29 patients were enrolled. Mean visual acuity on the logarithm of the minimum angle of resolution (log MAR) scale was 0.78 ± 0.34 at baseline, 1.01 ± 0.42 at 60 months, and 1.02 ± 0.41 at 120 months. Predominantly classic, minimally classic, and occult without classic choroidal neovascularization was noted in 51.7%, 17.2%, and 31.1% of patients, respectively. Visual acuity was improved by 1 or more lines in 27.6% of patients and was unchanged in 20.7% of patients, while 51.7% of patients had lost 1 or more lines of visual acuity by 120 months. Baseline visual acuity and age were associated with the final visual prognosis (p < 0.05). Four patients developed neovascular AMD in the contralateral eye. Conclusions: PDT is safe and effective for neovascular AMD. However, AMD can recur at any time and thus patients should be followed-up for a long period of time.

전강석(Gang Seok Jeon),한재룡(Jae Ryong Han),성현경(Hyun Kyoung Seong),김하경(Ha Kyoung Kim) 대한검안학회 2009 Annals of optometry and contact lens Vol.8 No.1

목적: 미숙아망막병증 선별검사도중 우연히 발견된 양측성 구형수정체(Lentiglobus)를 경험하였기에 보고하고자 한다. 대상과 방법: 재태연령 27주 2일 0.83 kg으로 출생한 환아로 미숙아망막병증의 위험으로 30주 5일부터 안저검사를 시행하였다. 결과: 환아는 stage I의 미숙아망막병증이 있었으나 자연적으로 호전되었고 추적관찰 중 재태연령 39주부터 도상검안경을 통한 적색반사가 수정체의 중심부와 주변부가 다른 양상으로 관찰되었으며 점차 진행하여 42주부터 완벽한 기름방울이 떠있는 모양의 구형수정체가 양안에서 관찰되었다. 시축을 가리는 수정체 혼탁은 관찰되지 않아서 경과관찰 하기로 하였다. 결론: 구형수정체는 진행성의 수정체 발달이상으로 대부분 초기에 경한 양상으로 시작하여 늦은 소아기까지 발견되지 않는 경우도 흔하다. 3세에서 15세 사이에 동반된 백내장과 함께 진단되는 경우가 보통인데 본 증례와 같이 출생 초기 짧은 기간에 진행성의 전형적인 양안의 구형수정체가 발견되는 경우는 드물어 문헌 고찰과 함께 보고하는 바이다. Purpose: To report a case of bilateral posterior lentiglobus in a premature infant by screening examination for retinopathy of prematurity. Methods: An 830 g 27 week 2 day gestation infant was consulted for screening examination about retinopathy of prematurity. Fundus examed 30 weeks 5 days gestation age. Results: Stage I retinopathy of prematurity improved spontaneously. Ring like reflex appeared in red reflex through indirect ophthalmoscope from 39 weeks gestational age in both eye and looks like oil droplet in water in the central red reflex at 42 weeks completely. Axial length was 17.74/17.65 mm in both, anterior chamber depth was 2.16/2.13 mm, lens diameter was 3.84/3.89 mm. There was no specific finding in B-scan. Central posterior lentiglobus portion had −0.25 Dsph −1.00 Dcyl * 90A refractive error in cycloplegic refraction. There was no opacity that cover visual axis. Conclusions: Posterior lentiglobus is progressive well circumscribed globular bulging of the posterior capsule of the lens. Generally it is detected with accompanied cataract between 3 and 15 year of age but this case shown bilateral progressive posterior lentiglobus in a short period at premature infant. So we report this rare case with literature review.

본 연구는 패널 데이터를 분석하여 청년층 취업자의 현 직장 근속연수에 영향을 미치는 결정요인을 검증하였다. 연구결과 청년층의 직장 근속연수에 영향을 미치는 요인은 성별, 연령, 최종학력(고졸 이하-대졸 이상 여부),혼인상태, 정규직 여부, 현 직장 임금, 현 직장 고용안정 만족도(p<.001), 가구 총 근로소득과 현 직장 복리후생 만족도(p<.01) 및 현 직장 인사고과 공정성 만족도(p<.05)로 나타났다. 또한 남성일수록, 연령이 높을수록, 기혼일수록, 근로소득이 낮은 집단일수록, 정규직일수록, 정년제일수록, 계속근로가 가능할수록, 업무내용과 전공이 일치할수록, 현직장 임금이 높을수록, 현 직장 만족도가 높을수록 근속연수가 길었다. 본 연구는 청년층의 직장 근속연수 결정요인을 밝힘으로써 장기적이고 안정적인 고용을 위한 효과적인 정책을 마련하는 데 시사점을 제공한 것에 의의가 있다. This study verified the determinants of years in service of youth employee by analyzing panal data. The study results showed that sex, age, education, marital status, full-time job, wage, employment stabilization, household earned income, benefit package, fairness of performance evaluation determined years in service of youth employee. Also, years in service was longer in male, higher age, married, lower household earned income, full-time job, age-limit system, possible to work continuously, corresponding to mager, higher wage, higher job satisfaction group. This study provided practical implication to prepare effective emplyment policy for maintaining long-term and stable youth employment by confirming the determinants of years in service of youth employee.

Autoimmune diseases are occasionally associated with other autoimmune diseases in the same patients. Autoimmune Graves' disease has been associated with systemic rheumatic diseases including systemic lupus erythematosus(SLE). And Graves' disease associated with idiopathic thrornbocytopenic purpura(ITP) has been reported many times in Korea. There is a special relationship between SLE and ITP, both of which are autoimmune diseases. Some patients with thrombocytopenic purpura, labeled as idiopathic at the onset, later develop a classical course of SLE, suggesting that ITP may be an early manifestation of SLE. The relationships among these three conditions and their pathogenesis are poorly undemtood, and the coexistence of these diseases at the same time has been reported very rarely, but it may be very probable that there are some relationships among them. We report a case of SLE associated with Graves' disease and ITP treated well by imunosup- pressive agent who had been suffering from recurrence by conventional treatments(antithyroid medication, corticosteroid, subtotal thyroidectomy and splenectomy).

Bleeding frorn the duodenal varix is an unusual event. Upper gastrointestinal endoscopy is the diagnostic procedure of choice in diagnosing duodenal varices. If performed during active bleeding, it can differentiate between esophageal and duodenal varices as the source, which has important therapeutic implications. A thorough examination of the duodenum for varices is important in an upper gastrointestinal hemorrhage. Treatment modalites for bleeding duodenal varices are sclerotherapy, varix suture ligation, portocaval shunt, and duodenal resection. Although endoscopic sclerotherapy has lirnited success in controlling active duodenal varix as initial treatment, endoscopic injection sclerotherapy is a useful first-line therapeutic measure in the treatment of bleeding duodenal varices. In this study we present a case of a ruptured duodenal varix, which was defected by an endoscopy, in a 61-year-old male. An endoscopic examination showed small and nonbleeding esophageal varices and a prominant ulcerated varix was identified in the 2nd portion of the duodenum. Endoscopic sclerotherapy was performed by injecting ethanolamine oleate into the varix. Our report demonstrate that endoscopic sclerotherapy can be efficient even in the presence of acute bleeding and that it can provide a definitive method of curing of a bleeding duodenal varix.
