당뇨망막병증의 치료에서 후테논낭하 트리암시놀론 주입술과 범망막광응고술 병합치료의 효과
강승범,박영훈,Seungbum Kang,Young-Hoon Park 대한안과학회 2008 대한안과학회지 Vol.49 No.1
`Purpose: To investigate the result of posterior sub-tenon triamcinolone acetonide injection combined with panretinal photocoagulation (PRP) in patients with diabetic retinopathy. Methods: A prospective study was performed on patients with diabetic retinopathy who required PRP. The study group consisted of 12 patients (12 eyes) of diabetic retinopathy without clinically significant macular edema (CSME) and 13 patients (13 eyes) with CSME. All patients were injected posteriorly with sub-tenon triamcinolone acetonide (40 mg) one week before PRP. During a six-month follow-up, best-corrected visual acuity, the development of macular edema, changes in fluorescein angiography, and related complications were monitored. Results: During a six-month follow-up, visual acuity was well preserved in patients with diabetic retinopathy without CSME (12 eyes). Only one patient in this group experienced temporary macular edema at 3 months after combined therapy. In the CSME group (13 eyes), the visual acuities of seven patients (53.8%) increased, those of five patients (38.5%) remained same, and one patient's visual acuity (7.7%) decreased in a study period of six months. Fluorescein angiography showed that macular edema was resolved in most patients except in one patient in whom macular edema remained for up to 6 months. Complications from combined therapy occurred in two patients who showed slight and temporary increase of intraocular pressure. Conclusions: Combined treatment with posterior sub-tenon triamcinolone acetonide injection and PRP may provide benefits for patients with diabetic retinopathy who require urgent PRP by preventing exacerbation of macular edema.`

Purpose: To report the relationship between hypertensive retinopathy and associated target organ damage in Korean hypertensive patients. Methods: A total of 519 hypertensive patients were divided into hypertension retinopathy grades I through IV based on fundus examination. According to the grade of each hypertensive retinopathy, the frequency of target organ damage (cardiovascular disease, chronic kidney disease, and retinal vessel occlusion) and the association with hypertension retinopathy were evaluated. Results: There were 211 patients (40.7%) without hypertensive retinopathy, 226 patients (43.5%) with hypertensive retinopathy grade I, 71 patients (13.7%) with grade II, seven patients (1.3%) with grade III and four patients (0.8%) with grade IV. The numbers of patients with cardiovascular disease were 103 (45.6%) in grade I, 57 (80.3%) in grade II, 3 (42.9%) in grade III, two (50.0%) in grade IV, and 70 (37.4%) in the non-hypertensive retinopathy group. According to four grades, the numbers of patients with cerebrovascular disease were three (1.3%), two (2.8%), zero (0%), and one (25.0%), respectively, with two (0.9%) in the non-hypertensive retinopathy patients. The respective numbers of patients with chronic kidney according to grades I through IV were 14 (6.2%), ten (14.0%), two (28.6%), and four (100.0%), as well as ten (4.7%) in the non-hypertensive retinopathy patients. The respective numbers of patients with retinal vessel occlusion were one (0.4%), two (2.8%), one (14.3%), and one (25.0%), with zero (0%) in the non-hypertensive retinopathy patients. Conclusions: The significance of hypertensive retinopathy should not be overlooked in Korean hypertensive patients due to an association with various target organ damage.

실리콘이 충전된 눈에서 부분결합간섭계를 이용한 인공수정체 도수계산
강승범(Seungbum Kang),노영정(Young Jung Roh) 대한검안학회 2012 Annals of optometry and contact lens Vol.11 No.1
목적: 실리콘이 충전된 눈에서 부분결합간섭계를 이용한 인공수정체 도수결정의 정확성을 알아보고자 하였다. 대상과 방법: 실험군은 실리콘이 충전된 눈에서 부분결합간섭계를 이용하여 인공수정체 도수를 정하고 실리콘기름 제거술과 인공수정체 삽입술을 동시에 시행한 10안을 대상으로 하였다. 대조군은 실리콘 기름을 제거한 후 초음파를 이용한 A-scan (Tomey, Nagoya, Japan)으로 인공수정체의 도수를 계산하고 단계적으로 인공 수정체를 삽입한 12안을 대상으로 하였다. 술 후 3개월째 실제 굴절값을 측정하였고, 목표 굴절값과 차이인 굴절예측이상값을 구하여 두 군의 굴절예측이상값의 평균을 비교하였다. 결과: 실험군의 술 후 3개월째 실제 굴절값의 평균은 -1.30±1.57디옵터였고 굴절예측이상값의 평균은 -0.08±1.04디옵터였다. 대조군의 술 후 3개월째 실제 굴절값이 평균은 -1.63±1.75디옵터였고, 굴절예측이상값의 평균은 -0.48±1.27디옵터였다. 두 군의 굴절예측이상값 사이의 평균은 통계적으로 유의하지 않았다(p=0.674). 결론: 부분결합간섭계는 실리콘이 충전된 눈에서 인공수정체 도수를 결정할 경우 유용하게 사용될 수 있다. Purpose: To evaluate the accuracy of intraocular lens (IOL) power calculation in eyes that have been operated on by silicone oil removal combined with IOL implantation using partial coherence interferometry. Methods: 10 eyes of 10 patients with silicone oil tamponade were included in this study. The IOL power calculation for 10 eyes was performed using partial coherence interferometry. 12 eyes of 12 patients with silicone oil tamponade were also included in this study as control group. 12 eyes in control group had IOL implantation after silicone oil removal. The IOL power calculation for control group was performed using conventional ultrasound A-scan (Tomey, Nagoya, Japan). Three months after silicone oil removal combined with IOL implantation, actual refraction was measured. To compare the difference between the actual and target refraction, refractive prediction error was calculated. It is defined as substraction of target refraction from actual refraction. Results: At three months, actual refraction and refractive prediction error of the group using partial coherence interferometry were -1.30±1.57 diopter and -0.08±1.04 diopter, respectively. At three months, actual refraction and refractive prediction error of the control group using ultrasound A-scan were -1.63±1.75 diopter and -0.48±1.27 diopter, respectively. There was no statistically significant difference between two values (p=0.674). Conclusions: Partial coherence interferometry seems to be satisfactory accurate method to calculate IOL power in silicone oil-filled eye.
