Purpose: To evaluate the effect of 9 mm and 7 mm bilateral recession of the superior rectus muscle in patients with bilateral dissociated vertical deviation (DVD) who had a deviation difference between the non-fixing and fixing eyes of less than 8PD. Methods: The subjects were chosen from the patients who visited our hospital for DVD between January 2001 and November 2003. We reviewed the surgical records of 19 patients who had undergone 9 mm recession of superior rectus muscle in the non-fixing eye and 7 mm in fixing eye, and who had been followed up for at least 6 months. Results: A residual DVD less than 8PD was regarded as successful. The overall success rate was 73.7%. The success rate of 10~14PD preoperative deviation of the non-fixing eye was 80.0%, and that of 15~19PD preoperative deviation of the non-fixing eye was 75.0%. However, the success rate was 66.7% in recession for the deviation over 20PD. Conclusions: Bilateral recession of 9 mm and 7 mm of the superior rectus muscle was effective for bilateral DVD in which the deviation difference of the non-fixing eye and fixing eyes was less than 8PD .

Purpose: To examine the effect of stellate ganglion block (SGB) in various types of glaucoma and ocular hypertension. Methods: The subjects were chosen from patients who visited our hospital for glaucoma and postoperative ocular hypertension in the 6-month period from A to B (Ed-give the dates). SGB was performed one or four times with 15 eyes from four types of glaucoma and postoperative ocular hypertension patients. The intraocular pressure (IOP) of eyes that had undergone SGB was checked after 1 hour following SGB. We investigated the efficacy of SGB on the 15 patients. Results: In primary open-angle glaucoma (POAG), early secondary glaucoma and post- operative ocular hypertension, the mean IOP of eyes that had undergone SGB decreased after 1 hour following SGB. However, in primary angle-closure glaucoma (PACG) and advanced secondary glaucoma, there was a rise in mean IOP after 1 hour following SGB. Conclusions: In the present study, SGB may be effective in treating POAG, early secondary glaucoma and postoperative ocular hypertension. However, in PACG and advanced secondary glaucoma, SGB may be considered to be harmful treatment modality.

Purpose: To report a patient with ocular ischemic syndrome who suffered from sudden decrease in visual acuity after bevacizumab injection. Case summary: A 70-year-old patient visited the Department of Ophthalmology due to progressively decreasing visual acuity in the right eye. Corrected visual acuity in his right eye was 0.1 on the first visit; ocular ischemic syndrome was suspected. Despite panretinal photocoagulation, severe iris neovascularization was still present in the right eye. Intravitreal bevacizumab injection was performed to regress the iris neovascularization. One day after injection, iris neovascularization regressed significantly, however, visual acuity was decreased to finger counting. Conclusions: In ocular ischemic syndrome, bevacizumab injection for reduction of iris neovascularization should be carefully considered due to possibility of acute visual loss.

Purpose: To report a case of recurrent uveitis associated with autoimmune liver disease. Case summary: A 50-year-old female with severe fatigue and arthritis visited the ophthalmology department due to decreased visual acuity and discomfort in her right eye for ten days. She had intermittent injection and blurred vision in both eyes for 30 years. Slit lamp examination of her right eye showed keratic precipitates, pigment deposits on the anterior capsule of the lens and anterior chamber cells; fundus examination was normal without any sign of chorioretinitis. Inflammatory reaction was improved after steroid and cycloplegic eye drop treatment. Two months later, her left eye developed anterior uveitis. Inflammation was well controlled with steroid and cycloplegic eye drop treatment. To evaluate the cause of uveitis and associated systemic disease, serological testing was performed, and abnormal elevation of liver enzymes was detected. The patient was referred to the Gastroenterology Department and diagnosed with autoimmune liver disease. Oral ursodeoxycholic acid was prescribed. Liver function profile improved to normal range, and the patient is currently under routine follow-up with no sign of recurrent uveitis. Conclusions: When a patient with recurrent uveitis presents symptoms such as nausea, fatigue, abdominal pain, jaundice or abnormal liver profile, association with autoimmune liver disease should be considered.

Purpose: The authors of the present case report observed a bilateral retinal racemose hemangioma which was located within the peripapillary area. Case summary: A 17-year-old man presented with floaters in both eyes. Fundus revealed tortuous and anastomosed retinal vasculature around the optic disc. In addition, fluorescein angiography showed a non-leaking retinal arteriovenous anastomosis. Seven years after the initial visit, vitreous hemorrhage occurred in the patient’s left eye, and then 1 year later, subretinal hemorrhage was found in his left eye. Conclusions: Because retinal racemose hemangioma can accompany vitreous hemorrhage and subretinal hemorrhage regardless of size, a routine periodic ophthalmic examination is recommended.

Purpose: A corneal epithelial debridement using three different instruments was performed in rabbits, and the rates of corneal epithelium recovery were compared. Additionally, the extent of corneal damage as determined by the scanning electron microscopy was evaluated in each group. Methods: Nineteen eyes of ten rabbits were classified into three groups according to the instruments used. The corneal epithelial debridement was performed using three different instruments: a Beaver blade (group A), a Bard-Parker blade No.15 (group B) and a dry cotton–tipped applicator (group C). After epithelial debridement, each cornea was observed every 24 hours for three days. After completion of the corneal recovery, each cornea was severed along the limbus and observed under the scanning electron microscope. Results: The rate of corneal epithelial healing of the group C (dry cotton-tipped applicator) showed no statistical significance from those of the other groups. However, according to the corneal status observed under scanning electron microscope after debridement, cracks in the corneal surface in portions of group A and B were observed in contrast with no creaks in group C. Conclusions: Based on these results, corneal epithelial debridement using a cotton-tipped applicator is expected to reduce the occurrence of postoperative corneal complications. Use of a dry cotton-tipped applicator for corneal epithelial debridement in vitreoretinal surgery is suggested. J Korean Ophthalmol Soc 2010;51(9):1264-1270

Relapsing polychondritis is a rare rheumatologic disorder most commonly presenting as recurring episodes of inflammation in cartilaginous tissues. Auricular chondritis with red ears resembling cellulitisis the most common clinical manifestation. Other manifestations include arthritis, nasal chondritis, and ocular, pulmonary, and cardiovascular disease. Here we report the case of a 54-year-old female patient with relapsing polychondritis and associated scleritis. On histologic examination, the auricle, including cartilaginous tissues, showed loss of the normal basophilia of cartilage and perichondrial infiltration of inflammatory cells. The patient was treated with systemic steroids. Symptoms in both auricles were reduced, scleritis developed, and ocular symptoms were waning. (Korean J Dermatol 2009;47(8):941~944)

목적: 제5기 국민건강영양조사 자료를 토대로 양안 시효율이 삶의 질과 연관성이 있는지 확인해 보고자 하였다. 대상과 방법: 제5기 국민건강영양조사에서 시력, 시야 검진 및 설문검사를 완료한 녹내장 혹은 녹내장 의증인 5,244명을 대상으로 연구하였다. 최대교정시력과 시야검사 결과를 토대로 양안 시효율을 계산하였으며, 삶의 질 평가는 EuroQoL 5D (EQ-5D) 설문을 이용하였다. 또한 시효율과 최대교정시력 두 변수를 이용하여 삶의 질에 대한 설명력을 비교하였다. 일원분산분석과 편상관분석을 이용하여 이들 간의 연관관계를 분석하였다. 결과: 녹내장 혹은 녹내장 의증인 대상자들에서 시효율과 좋은 눈의 최대교정시력 둘 다 EQ-5D 설문의 모든 지표에서 통계적으로 유의한 차이를 나타내었다(p<0.005). 나이, 성별, 소득, 교육, 직업, 배우자 여부, 자택 소유 여부를 통제한 후 분석한 삶의 질과의 관계에서 시효율은 상관계수 +0.040의 양의 상관관계가 있었으며(p=0.006), 좋은 눈의 최대교정시력은 상관계수 -0.044인 음의 상관관계가 있음을 확인할 수 있었다(p=0.002). 결론: 녹내장 혹은 녹내장 의증인 대상자들에서 시효율도 삶의 질과 통계학적으로 유의한 상관관계가 있었다. 좋은 눈의 최대교정시력뿐만 아니라 양안 시효율도 삶의 질에 영향을 미치는 것을 확인한 바, 시효율 역시 삶의 질에 대한 평가에 좋은 변수가 될 것으로 사료된다. 녹내장과 관련이 없는 일반인의 경우 추가적인 연구가 필요할 것으로 보인다. Purpose: To analyze the association of visual efficiency and quality of life using data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V). Methods: The present study included 5,244 glaucoma or glaucoma suspect subjects who completed a visual acuity test, visual field test and health-related questionnaire from the KNHANES V. Visual efficiency was calculated using best corrected visual acuity and visual field test. Quality of life was assessed with EuroQoL 5D (EQ-5D). Visual efficiency was compared with best corrected vision of the better eye to evaluate the relationship with quality of life. One-way analysis of variance (ANOVA) and partial correlations analysis were used to analyze the associations between factors. Results: Both visual efficiency and best corrected visual acuity of the better eye were significantly different with all EQ-5D parameters (p < 0.005). After controlling for age, gender, income, education, spouse and house ownership, visual efficiency showed a positive correlation coefficient of +0.040 (p = 0.006) with the quality of life and the best corrected visual acuity of the better eye showed negative correlation coefficient of -0.044 (p = 0.002) with the quality of life. Conclusions: Visual efficiency was associated with the quality of life. Not only visual acuity but also visual efficiency would be a valuable parameter when considering the quality of life. Further studies are needed to evaluate non-glaucomatous populations.
