  • Objectives : Strabismus is a disease that can be observed and treated directly from the outside. Therefore, it is very important in Korean medicine ophthalmology in accessibility to treatment. This study is designed to investigate the trends of strabismus-related studies published in Journal of Korean medicine. Methods : 5 Internet databases were selected to search for the study subject. The following 9 keywords were used; Strabismus, Heterophoria, Binocular vision, Visual acuity, Diplopia, Paralytic, Cover test, Oculomotor nerve paralysis, Abducens nerve paralysis. Through this process, a total of 45 studies were found and analyzed into 5 categories ; publication year, publication journal, number of author, type of article, analyzation of case report. Results : There were 2 review articles, 1 original article and 42 case reports. 5 studies(11.1%) were published in 2004 year. Journal of Korean Oriental Medical Ophthalmology & Otolaryngology & Dermatology were the most common with 40%. The authors were often 2 and 3 (each 22.2%). In the case report study, the treatment period was most often 1-30 days (35.7%). Conclusions : 42 studies were on paralytic strabismus and 1 study was on paralytic and non-paralytic strabismus. These results represent that the studies are concentrated in case reports about paralytic strabismus, but this seems to be an area to be improved in future research.

  • Objective : Deciphering the anatomy of posterior communicating artery (PCoA) aneurysms in relation to surrounding structures is essential to determine adjuvant surgical procedures. However, it is difficult to predict surgical structures through preoperative imaging studies. We aimed to present anatomical structures using preoperative high-resolution three-dimensional proton density-weighted turbo spin-echo magnetic resonance (PDMR) imaging with simple classification. Methods : From January 2020 to April 2022, 30 patients underwent PDMR before microsurgical clipping for unruptured PCoA aneurysms in a single tertiary institute. We retrospectively reviewed the radiographic images and operative data of these patients. The structural relationship described by PDMR and intraoperative findings were compared. Subsequently, we classified aneurysms into two groups and analyzed the rate of adjuvant surgical procedures and contact with the surrounding structures. Results : Correlations between preoperative PDMR predictions and actual intraoperative findings for PCoA aneurysm contact to the oculomotor nerve, temporal uncus, and anterior petroclinoid fold (APCF) reported a diagnostic accuracy of 0.90, 0.87, and 0.90, respectively. In 12 patients (40.0%), an aneurysm dome was located on the plane of the oculomotor triangle and was classified as the infratentorial type. Compared to the supratentorial type PCoA aneurysm, adjuvant procedures were required more frequently (66.7% vs. 22.2%, p=0.024) for infratentorial type PCoA aneurysm clipping. Conclusion : Preoperative PCoA aneurysm categorization using PDMR can be helpful for predicting surgical complexity and planning of microsurgical clipping.

  • Epidural steroid injection is one method of releiving chronic back pain. However, problems with the loss of resistance to air technique include the possible subarachnoid or subdural injection of air resulting in headache, venous air embolism, and the introduction of air bubbles into the epidural space. Pneumocephalus is a rare complication of epidural block for epidural steroid injection. We report a case of a 58-year-old woman who developed a severe headache and posterior nuchal pain with incomplete oculomotor palsy due to pneumocephalus occuring after an epidural steroid injection.

  • This paper presents a development of interface device for electro-oculogram(EOG) signal and it's application to the wireless mouse of wearable PC. The interface device is composed of five bio-electrodes for detecting oculomotor motion, several band-pass filters, instrumentation amplifier and a microprocessor. we have first analyzed impedance characteristics between skin and a bio-electrode. since the impedance highly depends on human face, it's magnitude differs from person. this interface device was applied to develop a wireless mouse for wearable PC, as a Bio Machine Interface(BMI). Where in the prompt on PC monitor is controlled by only EOG signals. this system was implemented in a Head Mount Display(HMD) unit. experimental results show the accuracy of above 90%.

  • Objectives: This study is to report a case of the paralytic strabismus with herbal medicine and acupuncture. Strabismus refers to the oculomotor muscles imbalance resulted from improper alignment of the visual axis of the two eyes. Our goal is to know the effectiveness and safety in children from oriental medicine. Methods: We treated the case by using herbal medicine, acupuncture, and etc. Results: We found that the case was recovered perfectly in short term(24days) without any side effects or complaints. Therefore, we try to apply this treatment in many children cases and to set as a guideline protocol to treat for children. Conclusions: The case showed proper oriental medical treatment is better choice for therapy than surgery or observation.

  • Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient's clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection. Our case suggests that surgeons should be aware of nasal vascularity before performing an operation, and that they should avoid injecting fillers at a high pressure and/or in excessive amounts. Additionally, filler injections should be stopped if the patient complains of severe pain, and appropriate measures should be taken to prevent complications caused by intravascular filler injections.

  • The patients with myotonic dystrophy (MD) show ocular motor abnormalities including strabismus, vergence deficits, and inaccurate or slow saccades. Two theories have been proposed to explain the oculomotor deficits in MD. The central theory attributes the defects of eye movements of MD to the involvement of the central nervous system while the muscular theory attributes to dystrophic changes of the extraocular muscles. A 58-year-old woman with MD showed selective slowing of horizontal saccades and reduced peak velocities for both horizontal canals in head impulse tests, while smooth-pursuit eye movements and vertical head impulse responses were normal. This case suggests that the extraocular muscles-as a final common pathway of the voluntary saccade and reflexive vestibular eye movements-may better explain the defective rapid eye movements observed in MD.

  • Acute ophthalmoparesis that includes the oculomotor, trochlear, or abducens nerve may occur as an initial presentation of Miller Fisher syndrome (MFS). The symptoms of MFS or variant forms of Guillain-Barre syndrome are pathogenically related to anti-GQ1b antibodies. We report a case of a 36-year-old man with unilateral isolated abducens nerve palsy associated with anti-GM1 antibody. To the best of our knowledge, this is the first report of unilateral isolated abducens nerve palsy with positivity for anti-GM1 immunoglobulin M antibody.
