Purpose: We report 2 cases of infectious endophthalmitis after intravireal triamcinolone acetonide injection which was successfully treated with early vitrectomy. Methods: A 56 year old male patient with chronic cystoid macular edema of right eye and an 84 year old female patient with diabetic macular edema of right eye (pseudophakic) eye were treated with intravireal triamcinolone acetonide injection. Four days after the injection, both the patients complained of decreased visual acuity that had been developed 1 and 2 days prior respectively. Visual acuity was hand motion, inflammatory cells, flare, fibrins and hypopyon were found in the anterior chamber. Fundus was not visible due to vitreous opacity. Results: The two patients were presumed to have infectious endophthalmitis. Anterior chamber irrigation, vitrectomy, intravitreal antibiotics injection, and vitreous culture were performed. Coagulase negative staphylococcus was detected from vitreous culture, Within 1 week of the follow-up procedures, the anterior chamber and vitreous inflammation were improved and visual acuity recovered to the level attained before intravireal triamcinolone acetonide injection. Conclusions: If after intravireal triamcinolone acetonide injection, there is severely decreased visual acuity, inflammation of the anterior chamber and vitreous, flare and fibrin are detected, infectious endophthalmitis must be suspected. If diagnosed early and treated with vitrectomy, a favorable visual prognosis is expected.

Purpose: To report one case of atypical Miller Fisher syndrome with spontaneous recovery. Methods: A 44-year-old woman was visited our clinic complaining of diplopia for 2 days. She has irregular medication history for thyroid dysfunction, and there was no antecedent respiratory or gastrointestinal infection. The best corrected visual acuity of both eyes was 20/20. She showed bilateral proptosis and limitation of abduction and supraduction, mild blepharoptosis of left eye and esotropia of 30 prism diopter (PD). Results: Thyroid fuction test, orbital CT and electromyography were normal. Cerebrospinal fluid (CSF) analysis revealed albuminocytologic dissociation. Steroid pulse therapy was started promptly, but there was no improvement. Extraocular movement and diplopia gradually improved after 4 weeks of onset. and spontaneously recovered completely after 2 months. Conclusions: We reported a case of atypical Miller Fisher syndrome that completely and spontaneously recovered within 2 months., and represented normal findings by every examination such as orbital CT, thyroid function test, electromyography and CSF analysis.

Purpose: To investigate the visual recovery and complications of vitrectomy in Terson`s syndrome. Methods: A retrospective study was carried out on 11 eyes in 9 patients who had undergone pars plana vitrectomy for Terson`s syndrome from October 2004 to June 2006. The factors assessed were age, gender, presence of hypertension, type of intracranial hemorrhage, preoperative and final visual acuity, time interval from intracranial hemorrhage (ICH) to vitrectomy, and any intraoperative and postoperative complications. Results: The average age of the subjects and the Interval from ICH to vitrectomy were 43.0±11.0 years and 3.25±3.48 months respectively. Binocular involvement was found in two of the nine patients, and fundus findings were severe vitreous opacity in all cases, while sub-ILM hemorrhage at the posterior pole was seen in five eyes. Intraoperative retinal break was recorded at the 10 o`clock sclerotomy site in five eyes, and four of these five eyes were associated with sub-ILM hemorrhage. One patient underwent a scleral buckling operation four months postoperatively due to rhegmatogenous retinal detachment associated with a retinal tear at the 2 o`clock sclerotomy site. Visual acuity improved in all cases postoperatively, and the final visual acuity was over 0.6 in seven eyes. Conclusions: We can expect from early surgery a relatively good prognosis of visual acuity and prevention of complications. Due to the possibility of retinal breaks at the sclerotomy sites, we should keep in mind that cautious handling of intraocular instrument and complete removal of vitreous base may be necessary.

Purpose: To examine the difference of clinical features according to age of onset of refractive accommodative esotropia. Methods: We retrospectively analyzed the medical record of 52 cases of refractive accommodative esotropia for more than 12 months of follow-up from March, 2000 to December, 2003. The factors we compared were gender, age of first ocular examination, interval from age of onset to first glasses, preoperative refractive error, amount of deviation corrected with hyperopic glasses, stereopsis and associated ocular conditions. Results: Cases were grouped according to age of onset. Fourteen (27%) patients were less than 2 years old., 32 (62%) were between 2 to 4 years old, and 6 (11%) were between 4 to 6 years old 6. the group less than 2 years old showed lower levels of preoperative refractive error than the group more than 2 years old. The younger the age of onset, the lager the deviation angle without hyperopic glasses. There were no differences according to age of onset in gender, interval from age of onset to first glasses, stereopsis, anisometropia or amblyopia. Conclusions: In refractive accommodative esotropia, the younger the age of onset is, the lager the deviation angle without hyperopic glasses and the greater the deviation can be corrected with hyperopic glasses

Purpose: To report a case of rapid resolution of subhyaloid hemorrhage and central retinal vein occlusion after medical treatment in acute myeloid leukemia Methods: A 13-year-old girl who had been diagnosed to have acute myeloid leukemia (AML) in the department of pediatrics was referred to the ophthalmologic clinic because of blurred vision in her both eyes for 1 week. Initial best corrected visual acuity was FC 30 cm in the right eye, 0.02 in the left eye. Fundus examination showed severe subhyaloid hemorrhage, dilated and tortous vein, retinal hemorrhage and papilledema. Hematologic tests revealed hemoglobin 5.2 g/dl, hematocrit 15.6%, white blood cell count 30,710/mm3 , platelete count 32,000/mm3. Results: After 1 week later, the findings of central retinal vein occlusion and papilledema were decreased and best corrected visual acuity was improved to 0.02 in the right eye, 0.08 in the left eye. 1 month later, subhyaloid hemorrhage and papilledema were markedly improved and hematologic findings was recovered to hemoglobin 8.6 g/dl, hematocrit 24.1%, white blood cell count 1,300/mm3 , platelete count 348,000/mm3. Finally, best corrected visual acuity was 1.0 in the right eye, 0.5 in the left eye and minimal macular edema was exist in the both eye. Conclusions: We suggest that the leukemic retinopathy in AML can be recovered rapidly after medical treatment in spite of severe retinal change.

손희진(Hee Jin Sohn),백혜정(Hae Jung Paik) 대한검안학회 2009 Annals of optometry and contact lens Vol.8 No.2

목적: 부분 조절내사시에서 양안내직근 증량 후전술 후 장기추적관찰을 통해 안위와 시력 및 입체시의 변화를 알아보았다. 대상과 방법: 부분조절내사시 진단하에 단일술자에 의해 근거리 기준 양안내직근 증량 후전술을 시행받고 최소 1년 이상 추적관찰이 가능하였던 22명의 의무기록을 후향적으로 분석하였다. 굴절이상, 원시교정 안경 착용 시와 미착용 시의 원거리 및 근거리 사시각 및 입체시가 수술 전에서 최종 진료시까지의 어떠한 변화를 보이는지 알아보았고 술 후 최대교정시력 및 약시 유무를 살펴보았다. 결과: 대상의 나이는 4.7±2.1세였고 추적관찰 기간은 평균 20.7±8.4개월이었다. 술 전 사시각 중 조절 부분이 22.4±8.3 Prism Diopter (PD), 비조절 부분이 31.8±8.7 PD였으며 술 후 1일째에 술 전의 원시안경 착용 시 14명(63.6%)은 10 PD 이내의 만족교정을, 3명(13.6%)은 과교정을, 5명(22.7%)은 부족교정을 보였다. 술 후 1년 이상 경과 관찰 후 안경교정 상태에서 최종 안위검사에서 19명(86.4%)이 만족교정 상태였으나 술 후 1일째 내사위를 보인 5명 중 3명은 결국 부족교정을 보였다. 약시가 없었던 환자 13명 중 1명을 제외하고는 모두 만족교정을 보였다. 수술 전후 입체시 검사가 가능했던 14명은 최종 검사 시 모두 3,000 sec of arc 이상의 입체시가 있었고 그 중 8명은 100 sec of arc 이상이었다. 결론: 부분조절내사시의 근거리 기준 증량수술 후 1년 이상 경과관찰 시 최종적으로 86%의 성공률을 보였으며, 특히 증량수술 후 적절한 안경의 교체처방 및 입체시의 호전이 수술 직후의 과교정을 극복하고 장기적인 정위 유지에 중요한 역할을 담당한다고 생각된다. 따라서 증량수술 후의 장기간의 정위를 위해서는 술 후 꾸준한 시력 및 입체시에 대한 관리가 중요하다. Purpose: To investigate the long-term outcome of patients with partially accommodative esotropia who had augmented bilateral medial rectus rectus recession. Methods: Retrospective review on the medical records of 22 partially accommodative esotropia patients, who had been under follow-up observation for at least one year following augmented bilateral medial rectus recession by one surgeon, has been performed. The amount of medial rectus recession was measured based on the near angle of deviation after full hyperopic correction. The surgical success were evaluated based on the best corrected visual acuity, refractive errors, degree of stereopsis and ocular positions with and without spectacle correction before surgery and final examination. Results: The mean age of the subjects was 4.7±2.1 years and the average follow-up period was 20.7±8.4 moths. The mean deviation angle of accommodative component was 22.4±8.3 PD, and the one of nonaccommodative component was 31.8±8.7 PD. Of the 22 patients, 14 (63.6%) revealed postoperative deviation of less than 10 PD, 3 (13.6%) and 5 (22.7%) exophoria and esophopia more than 11 PD, respectively, 1 day after surgery. 19 (86.4%) showed acceptable deviation at final examination and 3 of 5 who were esophopia at 1 day after surgery remained undercorrected at the final visit. At the last follow-up, best corrected visual acuity of higher than or equal to 0.7 has been found on 29 eyes (76%) out of 38 eyes of 19 patients, and binocular amblyopia and monocular amblyopia have been found on total of 6 patients, 3 patients of each. Out of 13 patients without amblyopia, 12 patients showed acceptable deviation. Titmus stereotest resulted in positive fly (3,000 sec of arc) in all 14 patients and more than 100 sec of arc in 8 patients. Conclusions: Surgical outcome in patients with partially accommodative esotropia who had augmented surgery based on the near angle of deviation had very satisfied. Augmented surgery provides some degrees of stereoacuity and fusion, and further management of ambyopia is important for better long-term results.

한대헌,손희진,이대영,남동흔,Dae Heon Han,Hee Jin Sohn,Dae Young Lee,Dong Heun Nam 대한안과학회 2011 대한안과학회지 Vol.52 No.3

Purpose: To investigate the results of 23-gauge sutureless vitrectomy and preoperative bevacizumab in diabetic retinopathy cases. Methods: A total of 212 eyes received pars plana vitrectomy by a single surgeon for proliferative diabetic retinopathy and were followed up for at least 6 months. The change of visual acuity and operative complications among the 20-gauge vitrectomy (group I, 86 eyes), 23-gauge vitrectomy (group II, 30 eyes), and 23-gauge vitrectomy with preoperative intravitreal bevacizumab (IVB) injection (group III, 96 eyes) were retrospectively analyzed. Results: One month postoperatively, visual improvement was better in groups II and III than in group I. Three months postoperatively, visual improvement was better in group III than in groups I and II. Six months postoperatively, visual improvement in group III was better than in group I, but there was no significant difference between group II and III. Intraoperative retinal breaks and postoperative vitreous hemorrhage were less common in group III than in groups I and II. Conclusions: In patients with proliferative diabetic retinopathy, 23-gauge sutureless vitrectomy showed faster visual recovery compared with 20-gauge vitrectomy, and vitrectomy with preoperative bevacizumab had less intraoperative and postoperative complications than vitrectomy without preoperative bevacizumab.

백혜정,손희진,Hae Jung Paik,Hee Jin Sohn 대한안과학회 2006 대한안과학회지 Vol.47 No.3

Purpose: To determine the result of early surgery for intermittent exotropia for children under 4 year old and the factors which affect it. Methods: The study subjects consisted of 25 children younger than 4 years who had received surgery for intermittent Exotropia. They were followed up for more than 1 year after surgery by the Department of Ophthalmology of the Gachon Medical School, between July 1998 and December 2003. The interval from onset to initial surgery, preoperative deviation angle, dissociated vertical deviation, stereopsis, preoperative patching, type of surgery, and initial postoperative deviation angle were compared and analyzed in a retrospective manner. Results: The average age of the subjects and the preoperative deviation angle were 3.2 years and 28.67±8.08PD respectively. The average deviation angle at postoperative year 1 was 5.60±8.69PD. Out of the 25 patients, 19 (76%) showed a deviation angle less than 10PD were and 4 (16%) had recurrence of exotropia. Consecutive esotropia occurred in 2 (8%). The clinical factor statistically related to results was the initial postoperative deviation angle. The group who had esophoria of more than 10 PD (18.27±6.18 PD) showed 93% orthophoria at postoperative year 1, which was statistically significant. Conclusions: Though a patient be under 4 years old, if their deviation angle is in progress or if non-surgical treatment is ineffective in the case when surgery is delayed, it is presumed that performing surgery at postoperative day 1 with an overcorrection of about 10 PD is preferred.
