백내장수술에서 윤부 이완절개법과 난시교정인공수정체의 난시교정효과 비교

박유연(Yooyeon Park),김만수(Man Soo Kim),김은철(Eun Chul Kim) 대한안과학회 2017 대한안과학회지 Vol.58 No.11

목적: 한국인 백내장 환자에서 난시교정인공수정체와 윤부이완절개술의 효과를 비교하고자 하였다. 대상과 방법: 1.25D 이상의 각막난시를 보인 79명 100안에 대하여 후향적으로 고찰하였다. 난시교정인공수정체군(54안)과 윤부이완절 개술군(24안), 일반인공수정체 삽입군(대조군, 22안)으로 나누어 수술 후 2, 6개월 경과 후 나안과 교정시력, 각막난시, 굴절난시를 비교분석하였다. 또한 대상자 중 2.5D 이하의 각막난시군을 따로 중등도 난시군으로 분류하여 추가 분석을 실시하였다. 결과: 수술 2개월 후 난시교정인공수정체군의 64.8%, 윤부이완절개술군의 41.7%, 대조군의 27.3%에서 0.1 logMAR 이상 나안시력을 보였다. 각막난시의 경우 술 전후 난시교정인공수정체군은 2.40 ± 1.33D에서 2.23 ± 1.42D, 윤부이완절개술군은 1.86 ± 0.44D에서 1.29 ± 0.55D, 대조군은 1.60 ± 0.39D에서 1.35 ± 0.60D로 윤부이완절개술군에서 가장 유의한 호전을 보였다(p=0.025). 굴절난시 에서 난시교정인공수정체군은 -2.48 ± 1.84D에서 -0.98 ± 0.92D, 윤부이완절개술군은 -2.02 ± 1.03D에서 -1.65 ± 0.86D, 대조 군은 -1.69 ± 0.88D에서 -1.49 ± 0.60D의 변화를 보였으며, 변화량은 난시교정인공수정체군에서만 유의하였다(p<0.001). 2.5D 이하의 각막난시를 보인 85안 중 굴절난시는 난시교정인공수정체군에서 0.97 ± 0.66D (55.1%)의 가장 높은 호전을 보였고(p<0.001), 윤부이완절개술군에서도 0.53 ± 0.87D의 유의한 변화를 보였다(p=0.046). 결론: 두 군 모두 대조군에 비하여 월등한 시력호전 및 난시 교정 결과를 보였으나 술 전 난시의 양에 관계없이 난시교정인공수정체 삽입술에서 가장 큰 호전을 나타냈다. 중등도 난시를 가진 환자에서는 윤부이완절개법을 통하여도 유의한 양의 난시 및 시력 교정효 과를 얻을 수 있어 경제적인 문제로 난시교정인공수정체 삽입을 꺼려하는 환자에게 유용한 수술이라고 사료된다. Purpose: To compare the effectiveness of toric intraocular lens (IOL) implantation and monofocal IOL implantation with a limbal relaxing incision (LRI) for correcting astigmatism in the Korean population. Methods: The medical records of 79 patients (100 eyes) with corneal astigmatism over 1.25 diopters (D) who underwent toric IOL implantation (toric group; 54 eyes), monofocal IOL implantation with a concurrent LRI (LRI group; 24 eyes), or monofocal IOL implantation without correcting astigmatism (control group; 22 eyes), were retrospectively reviewed. For subgroup analyses, the three groups were subdivided according to preoperative astigmatic severity under 2.5 D. Visual, refractive, and keratometric outcomes were compared 2 and 6 months postoperatively. Results: The uncorrected distance visual acuity was at least 20/25 (0.1 logMAR) in 64.8%, 41.7%, and 27.3% of the toric, LRI, and control group eyes, respectively at 2 months after surgery. The toric group had the greatest refractive cylindrical error change (toric group, -2.48 ± 1.84 D to -0.98 ± 0.92 D; LRI group, -2.02 ± 1.03 D to -1.65 ± 0.86 D; control group, -1.69 ± 0.88 D to -1.49 ± 0.60 D; p < 0.001) and the LRI group showed the greatest mean corneal cylindrical error change (toric group, 2.40 ± 1.33 D to 2.23 ± 1.42 D; LRI group, 1.86 ± 0.44 D to 1.29 ± 0.55 D; control group, 1.60 ± 0.39 D to 1.35 ± 0.60 D; p = 0.025). The 85 eyes with moderate corneal astigmatism (between 1.25 D and 2.5 D) were under evaluation. The toric group showed the highest mean refractive cylindrical change (0.97 ± 0.66 D; p < 0.001), followed by the LRI group (0.53 ± 0.87 D; p = 0.046). Conclusions: Both surgical techniques significantly reduced astigmatism and had comparable visual outcomes. Toric IOL implantation was more reliable for correcting astigmatism than monofocal IOL implantation with a concurrent LRI regardless of the preoperative astigmatic severity. Both procedures were effective in reducing astigmatism in eyes with moderate corneal astigmatism. J Korean Ophthalmol Soc 2017;58(11):1225-1233

박유연(Yoo yeon Park),성윤미(Youn Mi Sung),백지선(Ji Sun Paik),양석우(Suk Woo Yang) 대한안과학회 2016 대한안과학회지 Vol.57 No.7

목적: 내측 안와의 유피낭종으로 오인한 기생충 낭종 육아종 1예를 경험하여 이를 보고하고자 한다. 증례요약: 31세 남자 환자가 2년 전부터 서서히 크기가 증가하는 우안 내안각 안쪽 안와의 종괴를 주소로 내원하였다. 환자는 18년 전 동일 부위에서 안와 종양 제거술을 시행한 기왕력이 있었으나, 당시 조직검사는 시행하지 않았다고 하였다. 수술 전 검사한 안와전산화 단층 촬영에서 5.0 × 1.4 × 1.8 cm3 크기의 경계가 명확한 단방성 낭종이 관찰되었고 자기공명영상 T1에서 조영증강되어 일차적으로 유피낭종을 의심하였다. 앞쪽 안와 절개술을 통한 종양 절제술을 시행하였다. 수술 중 낭종이 천공되어 낭 내액을 주사기로 완전히 흡인하고 항생제를 섞은 생리식염수로 안와 내를 철저히 세척하였다. 병리조직 검사에서 분쇄된 기생충 성충이 발견되었고 만성 육아종으로 진단되었다. 결론: 안와 낭종에서 드물게 기생충낭이 진단되기도 하며 이 경우 전신 및 뇌 침범 가능성이 있으므로 주의해야 한다. 이때 유피낭종, 기생충낭 또는 다른 안와종양의 감별이 어려울 수 있어 조직병리 검사가 필수적이다. <대한안과학회지 2016;57(7):1154-1158> Purpose: To introduce a case of a cyst containing a parasite misdiagnosed as a dermoid cyst, which is to the best of our knowledge, the first report in Korea of a parasite in a cyst located at the medial side of the orbit. Case summary: A 31-year-old male visited the hospital with a 2-year history of a slowly growing mass at the medial side of the right orbit. The patient had a history of mass excision in the same location 18 years previously, however, biopsy was not performed at that time. Orbital computed tomography and magnetic resonance imaging revealed a 5.0 × 1.4 × 1.8 cm3 well-defined T1 high signal intensity unilocular cyst, thus our first impression was a dermoid cyst. The cyst was surgically removed with anterior orbitotomy. The cyst ruptured during the operation, and thus complete aspiration of the cystic fluid and in situ irrigation with antibiotics were performed. Histopathological examination revealed a fragmented adult parasite worm with chronic granulomatous change. Conclusions: A differential diagnosis for orbital cyst based on clinical and radiological results is difficult. Thus, histopathological confirmation is required. A cyst containing a parasite located in the orbit has rarely been reported. A full examination of all infected patients must be conducted for parasite infection.

Purpose: To report a case of cavernous sinus dural arteriovenous fistula who presented with painful isolated abducens nerve palsy along with the characteristic conjunctival features. Case summary: A 71-year-old female was referred to our clinic due to left eye pain and binocular diplopia. Esodeviation of 20 prism diopters was found with abduction limitation in the left eye. Slit lamp examination showed conjunctival injection, edema and corkscrew vessel dilatation in the left eye. Brain magnetic resonance angiography showed rapid filling and increased blood flow in the left superior ophthalmic vein and cavernous sinus. Cerebral angiography revealed direct venous drainage from the left cavernous sinus fistula into the left superior ophthalmic vein. After coil embolization, the left eye showed improvement in pain, conjunctival congestion and abduction limitation. Conclusions: Cavernous sinus dural arteriovenous fistula should be considered when characteristic symptoms and conjunctival signs are accompanied with painful isolated abducens nerve palsy.

This experiment was carried out to investigate the capability of meat production in two strains of broilers, Arbor Acres and Shaver Starbro. Eight chicks of each sex were slaughtered at 5, 6 and 7 weeks of age, respectively, in both strains, The results obtained were as follows: 1. Overall mean of the carcass weight was greater for the Arbor Acres than for the Shaver Starbro. 2. The lean meat weight of the Arbor Acres was heavier than that of the other strain. The lean meat ratio of the Arbor Acres was heavier at 6 weeks of age than either 5 weeks or 7 weeks. 3. The ratio of the average edible portion of the Arbor Acres to that of Shaver Starbro was positively deviated from unity. 4. Fat deposit in the carcass of male chicks, was gradually decreased with age increment, while the trend was opposit in female chicks. 5. Ratio of bone to carcass weight was highest at 5 weeks of age in both sexes. However, the ratio of muscle to carcass weight was high at 6 weeks and that of carcass fat at 7 weeks of age. 6. Carcass of male chicks had higher protein and moisture than that of female. The moisture was gradually decreased as the birds were getting older.

Purpose: This study’s aim was to confirm the importance and performance of the clinical practice of nurses working in the general wards of a tertiary hospital and to analyze their educational needs. Methods: The study employed a descriptive research design, and a self-reported questionnaire was developed and used for nurses in a tertiary hospital. Data were collected from July 22 to July 29, 2022, analyzed by an independent t-test, paired t-test, and one-way ANOVA for the importance and performance of each clinical nursing practice according to general characteristics, and then a post hoc verification was performed by Scheffé’s test. An Importance-Performance Analysis and Borich needs assessment model were used to analyze clinical nursing education needs. Results: Clinical nursing practice performance showed a significant difference according to length of total clinical career, time working in current department, and preceptor experience. According to the results of the Importance-Performance Analysis, neurological evaluation, and nursing intervention, artificial respirator and high-flow oxygen inhalation nursing, chemotherapy, emergency nursing, and cardiopulmonary resuscitation were identified as belonging to the “concentrate here” quadrant. All these items ranked in the top 10 in the Borich needs assessment model. Conclusion: Based on these results, the current education system should be reviewed, and short and long term education strategies based on educational needs should be established to strengthen the competence of nurses.
