`Purpose: To evaluate factors influencing stereoacuity outcomes after pediatric cataract surgery. Methods: We retrospectively reviewed 38 eyes of 22 patients who had undergone irrigation and aspiration of cataracts and primary posterior chamber intraocular lens implantation from February 1992 to July 2006. In all patients, stereoacuity was assessed with the Titmus stereo test. Patients were divided into two groups according to stereoacuity: group 1 (n=9) had a stereoacuity less than 100 sec/arc; group 2 (n=13) had a stereoacuity more than 100 sec/arc. Nine variables associated with stereoacuity were evaluated in each group. Results: Postoperative strabismus was the strongest factor influencing the stereoacuity level. Good postoperative mean visual acuity was related with good stereoacuity. Though mean visual acuity in two children with exodeviation over 30PD was 0.7 and 0.8, their stereoacuity was 400 sec/arc. Showing little difference in the spherical equivalent between the eyes was also related to good stereoacuity. Conclusions: Postoperative strabismus onset, postoperative mean visual acuity between the two eyes, and differences in the spherical equivalent were important factors influencing stereoacuity in patients after pediatric cataract surgery.`

Purpose: To evaluate height and symmetry of double folds following simultaneous levator palpebral muscle resection and double eyelid blepharoplasty for correction of blepharoptosis.Methods: We retrospectively studied 400 eyes of 286 patients who underwent simultaneous surgeries for double eyelid construction and correction of blepharoptosis from January 2006 to December 2011. All the patients were divided into three groups based on levator palpebrae muscle function: group A consisted of 82 eyes whose Levator Function Test (LFT) was 5 cm or less, group B consisted of 115 eyes whose LFT was between 5 and 10 cm, group C consisted of 203 eyes whose LFT was over 10 cm. For each group, we evaluated the preoperative marginal reflex distance 1 (MRD1), surgical methods, the postoperative height and symmetry of the double folds, and additional operations for correcting blepharoptosis. Results: Blepharoptosis surgery was performed in all groups by simultaneous levator resection and double eyelid blepharoplasty in all groups. Postoperative asymmetric double fold was the most common outcome observed in the poor levator function group A. Blepharoptosis under-correction was the most common cause of asymmetric double fold and its occurrence was statistically different between the three groups. The other causes were skin redundancy, brow elevation, double fold loosening, and blepharoptosis over-correction. Conclusions: The height of a double eyelid can be changed postoperatively by changing levator palpebrae muscle function. In cases of poor levator function, the levator palpebrae muscle is positioned slightly lower than the normal double fold. This condition may result in further relapse or recurrence in the poor levator function group. Also, levator function should be considered among the diverse factors that determine the height of the double fold. J Korean Ophthalmol Soc 2014;55(11):1579-1583

Purpose: To evaluate surgical results and complications of different intraocular lenses (IOL) implantation in pediatric cataract surgery. Methods: We retrospectively reviewed 139 eyes of 80 patients who had undergone irrigation and aspiration of cataracts and primary posterior chamber intraocular lens implantation with posterior continuous curvilinear capsulorhexis and optic capture from July 1998 to December 2005. All the eyes were divided into three groups into the intraocular lenses implanated: group 1 (n=40), PMMA lens was implantated; group 2 (n=42), hydrophobic acrylic lens was implantated; group 3 (n=57), hydrophilic acrylic lens was implanated. The surgical results and complications was evaluated. Results: Wound leakage, iris prolapse, shallow anterior chamber during operation were the most common in group 1. Peripheral anterior synechiae, conjuntival cyst, pigment deposition of IOL, exudative membrane, elevated intraocular pressure were also the most common in group 1 (P<0.05). There was no statistically significant defference in the prevalence of intraoperative and postoperative complications between group 2 and 3. Postoperative final visual acuity and astigmatism were not significantly different between the three groups. Conclusions: Implantation of hydrophilic acrylic IOLs, as well as hydrophobic acrylic IOLs decrease complications and have good surgical results compared to PMMA IOLs in pediatric cataract surgery.

N/A Twenty-nine patients who had frequent and/or complex ventricular premature beats on a 24-hour ambulatory ECG test were followed up for an average of 1 year and 7 months, and their prognoses were compared with those of 65 normal controls. Only one out of the 29 patients died of cardiac causes, (3.4%) but none of the normal controls died, This difference was not significant statistically. It did not make any difference, even when the presence of the underlying heart diseases were considered together. In our study of a limited number of patients in a rather short follow-up period, most of the patients who had frequent and/or complex ventricular premature beats had as good a prognosis as the general population.

권정민(Jeong Min Kwon),이재우(Jae Woo Lee),안정효(Jung Hyo Ahn) 대한안과학회 2017 대한안과학회지 Vol.58 No.2

목적: 피부샛길과 공동터널을 동반한 이마측두부위의 유피낭종으로 인해 반복되는 안와연조직염이 발생하여 항생제 치료와 수술적 제거로 호전된 경우를 경험하였기에 이를 보고하고자 한다. 증례요약: 4세 여자 환아가 좌측 안와 부종 및 압통을 주소로 내원하였다. 좌측 이마측두부위에 피부샛길이 있었으며, 소량의 농성 분비물이 나왔다. 안와전산화단층촬영 검사에서 좌측 이마-광대뼈봉합선 부근에 경계가 명확한 저밀도 내부의 음영을 가진 유피낭종이 의심되는 부위가 관찰되었으며, 측두오목과 연결되는 부위의 나비뼈 일부가 결손된 소견이 관찰되었다. 안와자기공명영상 검사에서 좌측 안와외측에 피부샛길과 연결된 공동터널이 관찰되었으며, 중간머리오목과 연결되었다. 안와연조직염을 치료하기 위해 항생제 주사치료 후 공동터널을 동반한 유피낭종을 제거하였다. 수술 후 뇌신경학적 및 안과적인 합병증은 없었으며, 현재까지 재발은 없었다. 결론: 안와 이마측두부위에 피부샛길을 통한 반복적인 분비물이 발생하는 경우 공동터널을 동반한 안와 심층부위의 유피낭종을 의심해보아야 할 것이며, 철저한 영상의학적 검사를 통해서 수술적 치료가 필요할 것이다. Purpose: To report the treatment results of a frontotemporal dermoid cyst with a cutaneous fistula and sinus tract that caused recurrent periorbital cellulitis in a child. Case summary: A 4-year-old girl who presented with left orbital swelling and tenderness visited our hospital. She had a cutaneous fistula with a small amount of purulent discharge at the left frontotemporal area. Orbital computed tomography scans showed a well-defined low density lesion in the fronto-zygomatic suture, and there was a bony defect in the left greater wing of the sphenoid bone of the orbit. Orbital magnetic resonance imaging showed a cutaneous fistula and sinus tract that extended into the middle cranial fossa. The patient was treated with intravenous antibiotics until the inflammation was resolved. Surgery was performed to remove the dermoid cyst with sinus tract. After surgery, there was no evidence of recurrence, and complications included neurologic and ophthalmic symptoms. Conclusions: Orbitofacial lesions, particularly frontotemporal cutaneous fistulas that present with recurrent discharge, should be regarded with suspicion in cases of deep extended dermoid cysts with sinus tract. Additionally, imaging tests should be carefully conducted before surgery.

목적: 4세 이하 선천성 코눈물관막힘 환아에서 나이에 따른 코눈물관탐침술의 효과를 분석하고자 한다. 대상과 방법: 선천성 코눈물관막힘으로 진단받고 코눈물관탐침술을 시행한 환아 146명(200안)을 대상으로 후향적 연구를 실시하였다. 연령에 따라서 A군(6개월 이하), B군(6개월 초과 12개월 이하), C군(12개월 초과 20개월 이하), D군(20개월 초과 48개월 이하)으로 분류하여 시술 당시의 나이, 성별, 시술의 양측성 여부, 경과 관찰 기간, 임상증상을 조사하고, 각 군별 양측성 여부, 탐침술의 횟수에 따른 코눈물관탐침술의 성공률을 비교 분석하였다. 결과: 첫 번째 탐침술의 성공률은 160/200안(80.0%), 연령별로 A군에서 87.5%, B군에서 85.7%, C군에서 77.6%, D군에서 76.7%로 확인되었으며, 각 군별 성공률은 유의한 차이가 없었다(p=0.550). 두 번째 탐침술은 총 40안에서 시행하였으며, 성공률은 25/40안 (62.5%)이었다. A군에서 100%, B 군에서 87.5%, C군에서 70.6%, D군에서 35.7%로 확인되었으며, 각 군별 성공률은 유의한 차이가 있었다(p=0.048). 시술의 편측성 여부에 따른 각 군별 탐침술의 성공률은 통계학적으로 유의한 차이가 없었다(p=0.291). 결론: 4세 이하의 환아에서 나이에 따른 첫 번째 코눈물관탐침술의 성공률에는 유의한 차이가 없었지만, 두 번째 코눈물관탐침술은 나이에 따른 성공률의 차이가 있었으며, 특히 20개월 이상에서 재시술 성공률은 감소하였다. Purpose: To analyze the effect of office-based probing in different age groups of children with congenital nasolacrimal duct obstruction. Method: A retrospective study was conducted in 146 children (200 eyes) diagnosed with congenital nasolacrimal duct obstruction who underwent office-based probing. The children were classified into four groups at the time of probing: group A (< 6 months), group B (> 6 months but < 12 months), group C (> 12 months but < 20 months), and group D (> 20 months but < 48 months). Age at the time of the procedure, gender, laterality, follow-up period, clinical symptoms, and the number of probings were investigated. Success rates were compared among the four groups in terms of sex, age, laterality, and the number of probings. Results: The success rate of the first probing was 160/200 eyes (80.0%). The success rates were 87.5% in group A, 85.7% in group B, 77.6% in group C, and 76.7% in group D. No significant difference in the success rate was observed according to age (p = 0.550). The second probing was performed in 40 eyes. The success rates were 100% in group A, 87.5% in group B, 70.6% in group C, and 35.7% in group D. A significant difference in the success rate was observed according to age (p = 0.048). The success rate of the second probing was 25/40 eyes (62.5%). No significant difference in laterality was observed among the four groups (p = 0.291). Conclusions: No significant difference in the success rate of first nasolacrimal duct probing was detected, but a significant differ￾ence in the success rate of the second probing was detected according to age in children < 4 years of age.

박영우(Young Woo Park),최재성(Jae Sung Choi),안정효(Jung Hyo Ahn),문영수(Young Soo Moon),유건(Gun Yu),김관엽(Kwan Yeop Kim) 대한소화기학회 1988 대한소화기학회지 Vol.20 No.3

N/A We have studied the gallbladder and its thickness by ultrasonography in 41 patients with acute hepatitis and 35 patients with chronic liver disease as control group. From 41 acute hepatitis patients, 33 (80.5%) had thickened GB wall. The average thickness in these patients was 4.66+2.52mm, which compared to control groups 2.34+0.86mm, was statistically significant. There were no significant differences in the GB wall thickness in etiologic classification of acute hepatitis (A, B, NANB type). The GB wall thickness measured at less than 1 week from the time when the symptoms were firstly noted was 7.67+0.58 mm, 5.75+2.22 mm at less than 2 weeks, 2.94+1.06 mm at less than 3 weeks. It was noted that as time progressed, the wall thickness showed a steady decrease, and after the 3 weeks period, it measured to 2.33+0.98 mm being close to the size of the control group. The mean GB wall thickness in those patients with the serum ALT level of greater than 500 IU/L measured on the average of the tenth day of the appearance of symptoms was 5.48+2.35mm compared to 3.37+1.70mm for the patients who were meausred on the average of the 16th day when the ALT level was at less than 500 IU/L. The greater GB wall thickness when the serum ALT level was in excess of 500 IU/L was most likely due to the fact that the measurement was done at the early period of the disease. When the serum bilirubin level was high, the GB wall thickness vas significantly increased, however the wall thickness was close to that of control group ivhcn the bilirubin level below 2.0 rng/dl. There was no statistical correlation between the serum alkaline phosphatase level and the GB wall thickness. In conclusion, most of the hepatitis patients showed a thickened GB wall in ultrasonography. This condition was severe at the clinical stage when the serurn ALT and bilirubin levels were high, but as the disease progressed to past the 3 weeks period, the GB wall normalized in most of the cases.

목적: 성인 코눈물관협착 환자에서 0.64 mm와 0.94 mm 굵기의 실리콘관삽입술의 성공률 및 합병증을 비교하고자 한다. 대상과 방법: 코눈물관협착증을 진단 받고 실리콘관삽입술을 시행한 환자 36명 62안을 대상으로 0.64 mm와 0.94 mm 실리콘관을 삽입하고, 두 군의 성별, 나이, 눈물 흘림 증상기간, 튜브제거 시기, 평균 경과관찰 기간, 수술 성공률을 조사하였다. 술 전 눈물소관 관류검사와 눈물주머니 조영검사를 바탕으로 협착 정도를 나누었으며, 협착 정도에 따른 수술 성공률과 두 군의 수술 합병증을 조사하였다. 결과: 실리콘관삽입술은 0.64 mm 굵기가 43안(69.4%), 0.94 mm 굵기가 19안(30.2%)에서 사용되었으며 0.64 mm와 0.94 mm 실리콘관삽입술의 성공률은 각각 84.1%, 78.9%였으나 통계학적으로 유의하지는 않았다. 술 전 눈물소관 관류검사 및 눈물주머니조영검사를 바탕으로 완전 협착보다는 부분 협착에서 수술 성공률은 높았으나, 실리콘관의 굵기에 따른 수술 성공률은 차이가 없었다. 실리콘관 끊어짐 및 꺾임 현상은 0.94 mm 실리콘관에서만 발생하였다. 결론: 성인의 후천적 코눈물관협착 환자에서 실리콘관삽입술을 시행할 경우 실리콘관의 굵기에 따른 수술 성공률은 차이가 없으나, 실리콘관의 끊어짐 및 꺾임현상은 0.94 mm 실리콘관에서만 발생하였다. Purpose: To compare surgical success rates and complications of silicone tube intubation using 0.64-mm- and 0.94-mm-diameter tubes in adult patients with nasolacrimal duct stenosis. Methods: In 62 eyes of 36 patients diagnosed with nasolacrimal duct stenosis who had undergone silicone tube intubation, we surveyed sex, age, symptom duration, time of tube removal, mean follow-up period, and surgical success rate between two groups divided by silicone tube diameter, 0.64 mm and 0.94 mm. By preoperative syringing test and dacryocystography, we examined the surgical results and complications of the two groups. Results: The silicone tube diameter was 0.64 mm in 43 eyes (69.4%) and 0.94 mm in 19 eyes (30.2%). The surgical success rates in the two groups were 84.1% (36 eyes) and 78.9% (15 eyes), respectively, but the difference was not significant statistically. The surgical success rate was higher in partial stenosis than in complete stenosis but was not different according to silicone tube diameter according to preoperative syringing test and dacryocystography. Silicone tube disconnection and bending were only observed in 0.94-mm-diameter silicone tubes. Conclusions: In silicone tube intubation for nasolacrimal duct stenosis in adults, silicone tube diameter does not affect operation success. However, silicone tube disconnection and bending were observed only in the 0.94 mm silicone tube.
