Purpose: To evaluate the efficacy of the radiofrequency surgical unit for the removal of benign tumors at the eyelid margin. Methods: Twenty-five benign tumors at the eyelid margin were removed with the Ellman Surgitron F.F.P.F. Histologic examination of the excised tumors was performed in 18 of the 25 cases. Results: There were 15 eyes of 15 females and 10 eyes of 10 males with age ranging from 20.9 to 73.5 years (mean, 41.8 years). Over a mean follow-up of 21.1 months, there was no instance of recurrence in any of the patients. In addition, there were no serious complications except temporary foreign body sensation and eye discharges. Conclusions: Using the radiofrequency surgical unit for benign tumors at the eyelid margin may simplify the surgery, avoid recurrence, and produce a satisfactory cosmetic effect.

망막분지정맥폐쇄로 인한 황반부종에서 허혈성과 비허혈성 간의 유리체강내 스테로이드주사의 효과 차이
최창욱,서상우,양연식.Chang Uk Choi M.D.. Sang Woo Seo M.D.. Yun Sik Yang M.D.. Ph.D. 대한안과학회 2007 대한안과학회지 Vol.48 No.1
Purpose: To investigate the improvement of visual acuity with the different effects of ischemic and perfusion type branched retinal vein occlusion (BRVO), and explore the relationship between defects of the macular capillary network and intravitreal injection of triamcinolone acetonide (IVTA) for treatment of BRVO secondary to macular edema. Methods: We compared macular capillary network condition, improvement of visual acuity due to ischemic range, and decrease of macular edema between 23 perfusion type BRVO patients and 21 ischemic type BRVO patients who were treated with IVTA for BRVO secondary to macular edema. Results: Both ischemic and perfusion type BRVO exhibited decreased macular edema and showed meaningful improvements in visual acuity (P<0.01), but did not show a relationship between the defects in the macular capillary network and improvement of visual acuity. No differences were seen in macular capillary network defects between ischemic and perfusion type BRVO. Conclusions: IVTA had an effect on the decrease in macular edema and improvement of visual acuity for both ischemic and perfusion type BRVO. However, defects in the macular capillary network do not seem to have any effect on the improvement of visual acuity.

눈물점폐쇄 환자에서 눈물점성형술과 실리콘관삽입술의 효과 비교

Purpose: To compare surgical results of two patient groups with punctal obstruction. One group underwent punctoplasty while the other group underwent silicone tube intubation. Methods: We compared postoperatively 48 eyes of 37 patients with punctal obstruction within and after one year of the procedure. 24 eyes of 17 patients had punctoplasty and 24 eyes of 20 patients had silicone tube intubation by the same surgeon. Results: Upon follow-up within one year after the punctoplasty, 13 eyes (54%) showed no epiphora, nine eyes (38%) showed intermittent epiphora, and two eyes (8%) showed persistent epiphora. However, after silicone tube intubation, 20 eyes (83%) showed no epiphora, three eyes (13%) showed intermittent epiphora, and one eye (4%) showed persistent epiphora. Over one year after the punctoplasty, one eye (4%) showed no epiphora, 19 eyes (78%) showed intermittent epiphora, and four eyes (17%) showed persistent epiphora. However, after the silicone tube intubation, 17 eyes (71%) showed no epiphora, six eyes (25%) showed intermittent epiphora, and one eye (4%) showed persistent epiphora. Conclusions: Silicone tube intubation is more effective than punctoplasty in the long term treatment of punctal obstruction. J Korean Ophthalmol Soc 49(4):543-547, 2008

양안 외향신경마비에 의한 눈모음고정사시의 수술 교정 1예
최창욱,김상덕,김재덕,Chang Uk Choi,Sang Duck Kim,Jae Duck Kim 대한안과학회 2006 대한안과학회지 Vol.47 No.10
Purpose: We report a case in which a convergent strabismus fixus due to head trauma-induced bilateral abducens nerve palsy was successfully corrected. Methods: A 45-year-old male patient who had bilateral,convergent strabismus fixus and limited eye movement because of bilateral abducens nerve palsy. A year previously, the patient had experienced a skull fracture and right facial nerve palsy caused by a traffic accident. At that time, the forced duction test revealed severe restriction of both eyes. The forced duction test still showed resistance after the right medial rectus muscle was disinserted. We made a conjunctival incision on the lateral canthal area and resected the right lateral rectus muscle. Then we performed lateral canthotomy, and fixed the lateral rectus muscle to the periosteum of the lateral orbital rim. When the left medial rectus muscle was disinserted, there was no resistance on the forced duction test. We then addressed the medial rectus muscle recession, superior and inferior rectus muscle transposition to the lateral rectus. Results: Two years after the procedure, bilateral convergent strabismus fixus did not recur, even though right eyeball movement was impossible. Patient appeared an orthophoria at the primary position, and the cosmetic rersult was satisfactory

관절경하에 Herbert Screw 를 이용한 슬관절 박리성 골연골염의 치료
이병일,최창욱 ( Byung Ill Lee,Chang Uk Choi ) 대한슬관절학회 1992 대한슬관절학회지 Vol.4 No.2
Between 1983 and 1991, we treated 10 knees of 8 patients with osteochondritis dissecans of the knee with arthroscopic Herbert screw fixation. The patients average age at the time of surgery was 20 and the average follow-up was 2 years and 3 months. The location of lesions were medial condyle in 7 knees, lateral condyle in 2 knees, and patella in I, The types of lesion were intact articular cartilage in 2 knees, detached articular cartilage in 7 knees, and 1oose fragment in 1. A second-look arthroseopy was performed on 4 knees to remove the Herbert screw. 3 of the 4 kaees had a sobd osteochondral fragment to probing after screw removal, and 1 demonstrated minimal fragment motion to probing after screw removal, 1 knee showed depression of fragment. Juxtaarticular tibial surface was not eroded in all 8 patients. Roentgenograms demonstrated 6 of the 10 lesions had complete union, 2 lesions, articular incongruity, 1 lesion, radiolucent line, and 1 lesion, mild degenerative changes. The average healing time was 10.2 weeks (8 - 16 weeks). According to the criteria of the Hughston rating scale for Osteochondritis Dissecans, there were 3 excellent, 5 good, 2 fair, no poor, and no failure. The results suggest that arthroscopic Herbert screw fixation is a useful and effective procedure for osteochondritis dissecans of the knee.
