윤이나,라상훈,이종혁,Ie-Na Yoon,Sang-Hoon Rah,Jong-Hyuck Lee 대한안과학회 2005 대한안과학회지 Vol.46 No.6

Purpose: To evaluate the effect of 9 mm and 7 mm bilateral recession of the superior rectus muscle in patients with bilateral dissociated vertical deviation (DVD) who had a deviation difference between the non-fixing and fixing eyes of less than 8PD. Methods: The subjects were chosen from the patients who visited our hospital for DVD between January 2001 and November 2003. We reviewed the surgical records of 19 patients who had undergone 9 mm recession of superior rectus muscle in the non-fixing eye and 7 mm in fixing eye, and who had been followed up for at least 6 months. Results: A residual DVD less than 8PD was regarded as successful. The overall success rate was 73.7%. The success rate of 10~14PD preoperative deviation of the non-fixing eye was 80.0%, and that of 15~19PD preoperative deviation of the non-fixing eye was 75.0%. However, the success rate was 66.7% in recession for the deviation over 20PD. Conclusions: Bilateral recession of 9 mm and 7 mm of the superior rectus muscle was effective for bilateral DVD in which the deviation difference of the non-fixing eye and fixing eyes was less than 8PD .

Purpose: To examine the effect of stellate ganglion block (SGB) in various types of glaucoma and ocular hypertension. Methods: The subjects were chosen from patients who visited our hospital for glaucoma and postoperative ocular hypertension in the 6-month period from A to B (Ed-give the dates). SGB was performed one or four times with 15 eyes from four types of glaucoma and postoperative ocular hypertension patients. The intraocular pressure (IOP) of eyes that had undergone SGB was checked after 1 hour following SGB. We investigated the efficacy of SGB on the 15 patients. Results: In primary open-angle glaucoma (POAG), early secondary glaucoma and post- operative ocular hypertension, the mean IOP of eyes that had undergone SGB decreased after 1 hour following SGB. However, in primary angle-closure glaucoma (PACG) and advanced secondary glaucoma, there was a rise in mean IOP after 1 hour following SGB. Conclusions: In the present study, SGB may be effective in treating POAG, early secondary glaucoma and postoperative ocular hypertension. However, in PACG and advanced secondary glaucoma, SGB may be considered to be harmful treatment modality.

Successful treatment of central retinal artery occlusion using hyperbaric oxygen therapy

김수한,차용성,이윤석,김현,Ie-Na Yoon 대한응급의학회 2018 Clinical and Experimental Emergency Medicine Vol.5 No.4

Central retinal artery occlusion (CRAO) is considered an ophthalmologic emergency. The prognosis of this disease is very poor. Currently, there is no generally effective therapy available to treat CRAO. Hyperbaric oxygen therapy (HBOT) can increase the volume of oxygen delivered to the ischemic retinal tissue until spontaneous or assisted reperfusion occurs. We report the case of a patient who experienced sudden visual loss due to CRAO that was treated with HBOT. The patient was an 81-year-old woman who presented with CRAO in her right eye (OD). She exhibited “hand motion” visual acuity before treatment. She underwent three sessions of HBOT at a pressure of 2.8 atmospheres absolute, performed over 3 days. After 4 days in hospital, her visual acuity improved to 0.4 (OD) for far vision and 0.5 (OD) for near vision. Her vision was stable without the supply of oxygen; therefore, she was discharged.

Case Report : Macular Infarction Associated with Reactive Arthritis

( Ju Young Kim ),( Jong Hyuck Lee ),( Ie Na Yoon ) 대한안과학회 2010 Korean Journal of Ophthalmology Vol.24 No.5

A 53-year-old woman visited the Department of Rheumatology with a chief complaint of a 3-day history of fever and chills and also presented with pain occuring in both knees at the time of outpatient visit. Based on rheumatologic and hematological lab studies, ultrasonography, and a needle aspiration biopsy of the articular cavity, the patient was diagnosed with reactive arthritis. On hospitalization day 3, consultation with the Department of Ophthalmology was requested regarding decreased visual acuity lasting for 3 days. Upon ophthalmologic examination, the corrected visual acuity was 0.1 in the right eye and 0.05 in the left eye. Upon slit lamp microscopy, there were no abnormal findings in the anterior segment. Upon fundus examination, however, there were yellow-white lesions in the macular area of both eyes. Fluorescein angiographywas performed to assess the macular lesions, and the findings were suggestive of macular infarction in both eyes. Due to a lack of other underlying disease, a past surgical history, and a past history of drug administration, the patient was diagnosed with macular infarction in both eyes associated with reactive arthritis. To date, there have been no other such cases reported. In a patient with reactive arthritis, we experienced a case of macular infarction in both eyes, which occurred without association with a past history of specific drug use or underlying disease. Herein, we report our case, with a review of the literature.

Original Articles : Clinical Progress in Impending Central Retinal Vein Occlusion

( Dong Hoon Lee ),( Seok Joon Lee ),( Ie Na Yoon ) 대한안과학회 2010 Korean Journal of Ophthalmology Vol.24 No.2

Purpose: Impending central retinal vein occlusion is associated with mild or no loss of vision; however, its progress and vision prognosis have not been clearly defined until now. Therefore, we studied the progress and prognoses in patients with impending central retinal vein occlusion. Methods: For this study, we selected ten subjects who had been diagnosed with impending central retinal vein occlusion, and we retrospectively reviewed their progress and prognoses. Results: The average age of the subjects was 31.0 years (18 to 48 years). Eight patients were male and two were female. The average observational period was 5.5 months. Six out of ten subjects were found to have no underlying systemic disease, four subjects had underlying disease. All ten patients were affected unilaterally. When initially tested, the affected eyes showed an average vision of LogMar 0.30. The final vision test revealed an average of LogMar 0.04, which indicates good progress and prognosis. In one patient, retinal hemorrhage and macular edema progressively worsened after the diagnosis, and the patient was treated with radial optic neurotomy. Conclusions: The cases of impending central retinal vein occlusion that we observed seemed to primarily affect young patients with generally good prognoses. However, in some cases, the degrees of obstruction and hemorrhage increased as time progressed. This suggests that impending central retinal vein occlusion could develop into the prodromal phase of an acute attack.

안허혈증후군 환자에게 유리체강내 베바시주맙 주입 후 발생한 급격한 시력저하

김진우,윤이나,Jin Woo Kim,Ie Na Yoon 대한안과학회 2012 대한안과학회지 Vol.53 No.12

Purpose: To report a patient with ocular ischemic syndrome who suffered from sudden decrease in visual acuity after bevacizumab injection. Case summary: A 70-year-old patient visited the Department of Ophthalmology due to progressively decreasing visual acuity in the right eye. Corrected visual acuity in his right eye was 0.1 on the first visit; ocular ischemic syndrome was suspected. Despite panretinal photocoagulation, severe iris neovascularization was still present in the right eye. Intravitreal bevacizumab injection was performed to regress the iris neovascularization. One day after injection, iris neovascularization regressed significantly, however, visual acuity was decreased to finger counting. Conclusions: In ocular ischemic syndrome, bevacizumab injection for reduction of iris neovascularization should be carefully considered due to possibility of acute visual loss.

Refractive Change Caused Silicone Oil Adhesion to the Intraocular Lens Following Nd:YAG Posterior Capsulotomy

Dong Hoon Lee,Sang Hoon Rah,Ie Na Yoon 대한안과학회 2009 Korean Journal of Ophthalmology Vol.23 No.4

A 32-year-old female who had undergone the silicone oil removal procedure presented with visual disturbance in her left eye. Several months previous, she had cataract surgery in a private clinic, and a month later she had a Nd:YAG laser procedure for posterior capsulotomy. The slit-lamp examination revealed silicone oil droplets that had adhered to the intraocular lens where the posterior capsulotomy was performed. She had experienced high myopia as a manifestation of the resulting refractive changes. We replaced the previous intraocular lens with a new acrylic intraocular lens with resulting improvement to her vision. Here we report the case of a female patient with a history of silicone oil removal surgery where the resulting silicone bubbles had not been removed thoroughly and remained in the vitreous cavity. These bubbles subsequently adhered to the intraocular lens following YAG laser posterior capsulotomy, resulting in refractive changes. We recommend that implanting a silicone intraocular lens in anyone with a history of the silicone oil removal procedure or who has a possible history of silicone oil use should be avoided.

시신경 유두부 주위에 국한된 양안 망막 포도송이 혈관종 1예

우영준,이윤하,윤이나.Young Jun Woo. MD. Yoon Ha Lee. MD. Ie Na Yoon. MD 대한안과학회 2011 대한안과학회지 Vol.52 No.11

Purpose: The authors of the present case report observed a bilateral retinal racemose hemangioma which was located within the peripapillary area. Case summary: A 17-year-old man presented with floaters in both eyes. Fundus revealed tortuous and anastomosed retinal vasculature around the optic disc. In addition, fluorescein angiography showed a non-leaking retinal arteriovenous anastomosis. Seven years after the initial visit, vitreous hemorrhage occurred in the patient’s left eye, and then 1 year later, subretinal hemorrhage was found in his left eye. Conclusions: Because retinal racemose hemangioma can accompany vitreous hemorrhage and subretinal hemorrhage regardless of size, a routine periodic ophthalmic examination is recommended.

Valsalva Retinopathy Associated With an Oratorical Contest

Ju Young Kim,Dong Hoon Lee,Jong Hyuck Lee,Ie Na Yoon 대한안과학회 2009 Korean Journal of Ophthalmology Vol.23 No.4

A 17-year-old man presented to us with a chief complaint of decreased visual acuity accompanied by central scotoma. There was nothing unusual in his medical history other than a recent oratorical contest. At the time of initial diagnosis, the corrected visual acuity was 20/20 in the right eye and 20/100 in the left eye. No significant findings were apparent on ophthalmic evaluation. On fundoscopy, there was a dumbbell-shaped macular bleed with a well-defined margin in the left eye. The clinical course was closely monitored along with drug therapy. Four weeks post presentation, the pre-retinal hemorrhage had nearly resolved. On fluorescein angiography, no significant findings were observed. In the left eye, the corrected visual acuity had improved to 20/25. Valsalva retinopathy is a pathology that occurs when a sudden increase in intra-thoracic pressure or abdominal pressure occurs in an otherwise healthy person. Here we report a case of Valsalva retinopathy occurring following an oratorical contest along with a review of the relevant literature. Korean J Ophthalmol 2009;23:318-320
