Purpose: To evaluate the long-term therapeutic effects of intravitreal bevacizumab on myopic choroidal neovascularization (CNV). Methods: Medical records of 6 patients who underwent intravitreal bevacizumab injection for myopic CNV and were followed for more than 2 years, were retrospectively investigated. The best corrected visual acuity was compared at 1,3,12, and 24 months after injection. Two years after the injection, a fluorescein angiography and optical coherence tomography (OCT) were performed to evaluate the central macular thickness and leakage of CNV. Results: The mean best corrected visual acuity was 1.16 ± 0.43 (logMAR), 0.45 ± 0.21 (logMAR), 0.29 ± 0.23 (logMAR), 0.14 ± 0.11 (logMAR), and 0.11 ± 0.06 (logMAR) at baseline, 1, 3, 12, and 24 months after injection, respectively. The average number of injections was 1.33. In OCT, 2 years after bevacizumab injection, central foveal thickness was significantly decreased as compared to the baseline, and fluorescein angiography showed no leakage of fluorescein. Conclusions: Intravitreal bevacizumab injection for the treatment of myopic CNV was effective in maintaining postoperative visual acuity for 2 years. J Korean Ophthalmol Soc 2011;52(1):34-40

Methods: A retrospective chart review was conducted of medical records of 38 patients who underwent pneumatic retinopexy using SF6 gas from January 2003 to December 2011 and who were observed during a follow-up period longer than 6 months. Primary and final success rates and final visual acuity were analyzed. Primary success was defined as retinal attachment at the last visit without additional surgery. Final success was defined as retinal reattachment at the last visit regardless of additional surgery. Results: The mean patient age was 58.47 ± 17.00 years. All retinal tears were located in the upper retina (from 8 to 4 o’clock). Preoperative mean visual acuity was 1.17 ± 1.00 log MAR, and postoperative mean visual acuity was 0.42 ± 0.48 log MAR. The primary success rate was 61%, and patients with re-detached retina underwent repeat pneumatic retinopexy or other surgery such as scleral buckling or pars plana vitrectomy. At the final visit, all of the patients demonstrated successful results. Conclusions: Pneumatic retinopexy does not result in strabismus or refractive error, and the final success rate was 66% in our study. Therefore, pneumatic retinopexy can be considered as an effective management technique for some pseudophakic retinal detachment patients. J Korean Ophthalmol Soc 2016;57(6):935-940

목적: 망막분지정맥폐쇄 환자에서 진단 초기에 망막출혈 흡수 비율과 망막분지정맥폐쇄의 임상양상의 관계를 보고하고자 한다. 대상과 방법: 망막분지정맥폐쇄로 진단받은 66안을 대상으로 후향적인 조사가 이루어졌으며, 망막출혈의 흡수량을 비교하기 위하여 그리드(grid)라는 정량적인 측정 단위를 사용하였다. 그리드 총량의 변화값을 이용하여 초기의 망막출혈 흡수 비율을 측정하였고 장기적인 환자군의 임상적 양상과 유의성을 확인하였다. 결과: 망막분지정맥폐쇄로 진단받은 환자군의 초기 망막출혈 흡수 비율(Σgrid/month)은 16.5 ± 21.5였다. 12개월 동안 최대교정시력의 호전 정도는 0.3 ± 0.3이었고 초기 망막출혈 흡수 비율과 유의하였다(p<0.01). 초기 망막출혈 흡수 비율이 7.5보다 낮은 느린 집단과 높은 빠른 집단으로 분류하여 비교하였을 때, 관찰 기간 동안 최대교정시력의 호전 정도는 느린 집단에서 0.16 ± 0.23이고 빠른 집단에서 0.38 ± 0.28이며 유의하였다(p=0.01). 중심와두께의 완화 정도는 흡수 비율이 느린 집단에서 133.12 ± 142.93 μm였고, 빠른 집단에서 236.62 ± 131.55 μm였으며 유의성을 보였다(p<0.01). 결론: 망막분지정맥폐쇄 환자군에서 지속적인 경과 관찰이 이루어질 때, 초기의 망막출혈 흡수 변화 비율이 예후를 예측할 수 있는 하나의 지표로서 생각해 볼 수 있겠다. Purpose: We report the relationship between early retinal hemorrhage absorption rate (RHAR) and long-term clinical outcomes associated with branch retinal vein occlusion (BRVO). Methods: This retrospective study included 66 eyes with BRVO. We used a grid as a quantitative measurement unit for measuring the amount of hemorrhage, and calculated the RHAR by measuring variance between sums of the grids. We investigated the relationship of best corrected visual acuity (BCVA), central foveal thickness (CFT), and other long term clinical outcomes with RHAR. Results: The RHAR in BRVO patients measured 16.46 ± 21.48 Σgrid/time (month). Improvement of BCVA (logMAR) was 0.28 ± 0.28 at 12 months, showing statistical significance with the RHAR (p < 0.01). We divided RHAR into two groups by 7.5 Σ grid/month; slow and fast RHAR groups. Improvement of BCVA (logMAR) was 0.16 ± 0.23 in the slow RHAR group, and 0.38 ± 0.28 in the fast RHAR group, with statistical significance (p = 0.01). Regression of CFT was 133.12 ± 142.93 μm in the slow RHAR group, and 236.62 ± 131.55 μm in the fast RHAR group, with statistical significance (p < 0.01). Conclusions: RHAR may be a prognostic factor during follow-up in BRVO patients.

박지웅(Ji Woong Park),서영승(Young Seung Seo),경성은(Sung Eun Kyung) 대한검안학회 2015 Annals of optometry and contact lens Vol.14 No.1

Purpose: We report a case of presumed optic nerve infiltration associated with the leptomeningeal seeding of the 37- year-old breast cancer patient complaining sudden diplopia. Case summary: A 37-year-old woman receiving chemotherapy because of inoperable breast cancer presented to us with a sudden onset diplopia. The ophthalmologic examination demonstrated a 25 prism diopter esotropia at primary gaze, 30 prism diopter esotropia at the right gaze and abduction limitation in the right eye. The fundus exam showed bilateral papilledema. Visual acuity, anterior segment exam, visual field test and color vision test were normal. Brain magnetic resonance imaging showed no parenchyme infiltration and no enhancement lesion. In the results of cerebral spinal fluid exam, the elevated intracranial pressure (345 mm Hg) and the malignant cells were observed. The diplopia was improved right after lumbar puncture. But 1-month after controlling the intracranial pressure, the aggravating disc edema and color vision abnormalities of the both eyes were founded. Conclusions: Breast cancer is the most common primary site of the ocular metastatic tumors. In the eye, highly vascularized choroid is the most frequently metastasis site of the breast cancer. We experienced presumed optic nerve infiltration, which the papilledema were aggravated while controlling intracranial pressure, in patient diagnosed as the leptomeningeal seeding of breast cancer.

Purpose: The evaluation of a lecture by students is one of the good way to improve a lecture. In one medical school, we started one-year-integrated-lecture curriculum for sophomore. And we evaluated lectures using formal lecture evaluation sheet after completion of each integrated lectures. The results were fed back to lecturers. But lecturers were indifferent to the results. So we performed this study to evaluate the current lecture evaluation method. Methods: Answering patterns of evaluation sheets were reviewed. 50 students entitled to integrated lectures were given structured questions. 44 of them recovered. And randomly selected 10 students were interviewed. Results: Analysis of evaluation sheets showed that some students checked the items just for fun. More than half of the students answered that they did not check the questions seriously. Reasons why the evaluation of lectures were not going well were; students were not trained to evaluate something; evaluation sheet was not designed to evaluate individual lecturer; listed items were too many in number and inappropriate; some students were suspicious about the impact of evaluation of lectures. In addition to this, it was revealed that students thought the timing of evaluation of lecture was important, too. Conclusion: Indifference of lecturers to the results is one form of resistance to the evaluation of lectures by students. To make evaluation of lectures effective, numbers and contents of evaluation items must be selected carefully, students need to be trained, and adequate evaluation timing should be determined with frequent feed backs.
