  • Recently, there has been tremendous increase in human-computer/machine interaction system, where the goal is to provide with an appropriate service to the user at the right time with minimal human inputs for human augmented cognition system. To develop an efficient human augmented cognition system based on human computer/machine interaction, it is important to interpret the user's implicit intention, which is vague, in addition to the explicit intention. According to cognitive visual-motor theory, human eye movements and pupillary responses are rich sources of information about human intention and behavior. In this paper, we propose a novel approach for the identification of human implicit visual search intention based on eye movement pattern and pupillary analysis such as pupil size, gradient of pupil size variation, fixation length/count for the area of interest. The proposed model identifies the human's implicit intention into three types such as navigational intent generation, informational intent generation, and informational intent disappearance. Navigational intent refers to the search to find something interesting in an input scene with no specific instructions, while informational intent refers to the search to find a particular target object at a specific location in the input scene. In the present study, based on the human eye movement pattern and pupillary analysis, we used a hierarchical support vector machine which can detect the transitions between the different implicit intents - navigational intent generation to informational intent generation and informational intent disappearance.

  • Background: A number of studies have identified the effect of Korean medicine treatment for oculomotor nerve palsy, but few have reported treatment of subarachnoid hemorrhage. This paper reports two cases of oculomotor nerve palsy with ptosis and limitation of eye movement after subarachnoid hemorrhage whose conditions were improved by Korean medicine treatment. Methods: Two patients with ptosis and limitation of eye movement after subarachnoid hemorrhage were treated with Korean medicine, including acupuncture, electroacupuncture, herbal medicine, cupping, moxibustion, and pharmacoacupuncture. Clinical symptoms were measured as the distance of the interpalpebral fissure and eyeball movement (adduction, abduction). Results: After treatment, their clinical symptoms showed improvement. Conclusion: Korean medicine treatment, including pharmacoacupuncture and electroacupuncture, could be adopted as a treatment method for oculomotor nerve palsy after subarachnoid hemorrhage.

  • Posterior communicating artery aneurysms (PcomAAs) are the second most common type of aneurysm. Large cerebral aneurysms show various neurological symptoms, especially oculomotor nerve palsy (ONP), due to PcomAAs. Recent research has shown that stent-assisted coil embolization has many side effects. We report the effectiveness of Korean medicine in the treatment of ONP due to PcomAAs after stent-assisted coil embolization. A patient with ptosis and limitation of eye movement was treated with Korean medicine, including herbal medicine (Samlyeongbaegchul-san-byeonbang [參苓白朮散變方] and Uwhangchungsim-won [牛黃淸心元]), acupuncture, electroacupuncture, cupping, and moxibustion. Clinical symptoms were observed by images of the inter-palpebral fissure and eyeball movement. After the treatment, the inter-palpebral fissure and eyeball movement were noticeably improved. These findings suggest that treatment with Korean medicine can be an effective option for the treatment of ONP due to PcomAAs after stent-assisted coil embolization.

  • Schwannomas are well-differentiated solitary benign tumors that originate from the schwann cells of the nerve sheath. They can readily occur in the head and neck regions, but the schwannoma originating from the infraorbital nerve is extremely rare and usually painless, slow-growing, and without specific symptoms. The author experienced a rare case of infraorbital schwannoma, which was completely removed through the intraoral approach. A 20-year-old woman was admitted to our hospital for a painless, solid and circular mass located on the right infraorbital region. The eyeball movement and visual field were normal. There was no globe displacement or proptosis. Preoperative computed tomography demonstrated $13{\times}10{\times}5mm$-sized soft tissue mass. On March 2011, the mass was removed through an intraoral approach. On histopathological examination, the gross specimen consisted of a smooth, well-encapsulated and light yellowish solid mass, measuring $12{\times}7{\times}5mm$. Microscopically, it presented a typical manifestation of schwannoma with Antoni A area with Verocay body, and Antoni B area on H&E stain. The result of the immunohistochemical staining was positive for the S-100 protein. The patient had hypoesthesia of the nasal septum and vestibule in the postoperative period, and this finding confirmed that the internal nasal branch of infraorbital nerve was the nerve in which the schwannoma originated. Infraorbital schwannomas are very rare and must be included in the differential diagnosis of the orbital masses inferior to the eyeball. In the case of early diagnosis, the small-sized infraorbital schwannomas can be completely removed without any scar through an intraoral approach.

  • Oculomotor nerve palsy is a disorder which causes eyeball movement trouble, dipleopia, dizziness and eyelid ptosis. It is caused by aneurysm, mass, truma, intracranial hypertension, diabetes mellitus, infection and so on. But sometimes we can't establish the cause. We report a case of oculomotor nerve palsy associated with spleen energy(脾氣). We treated a patient with herb medicine and acupuncture. This study suggests that oriental medicine theraphy has a good effect on the oculomotor nerve palsy.

  • Internuclear Ophthalmoplegia (INO) is characterized by lesion side eye's adduction limitation in lateral horizontal gaze and nystagmus in the abducting eye due to lesions in the Medial Longitudinal Fasciculus (MLF). Brainstem infarction is one of the causes of INO, but related issues have seldom been reported in the Korean medical literature. The present case was a pontine infarction patient with INO who complained of diplopia and eye movement disorder. The patient was treated with Korean medicine treatment, including herbal medicine, acupuncture, cupping, and moxibustion for 30 days. Her changes in clinical symptoms were measured with a Numeric Rating Scale (NRS) and a length of External Ocular Movement (EOM), in which the patient's right eyeball moved to the left from the midline in the left gaze. After treatment, her clinical symptoms were improved. Diplopia decreased from NRS 10 to NRS 2, and eye movement disorder was improved such that EOM increased from 1mm to 5 mm. Therefore, integrative Korean medicine treatment may be effective in the treatment of INO patients caused by pontine infarction.

  • This study aims to analyze the association between the center of mass(C.O.G) and ocular movement(E.O.G) according to the success and failure in the left turn motion on the balance beam, targeting three female gymnasts. When successful, the left-right C.O.G was moved to the left, which was a rotational direction until such time as the body rotated $180^{\circ}$, whereas there appeared to be a greater movement during failure; thus, it was shown to affect the maintenance of dynamic postural control. In case of the subsequent left-right turning motion of E.O.G, this matches the previous theory that the eyeball moves against the direction of rotation of the body. However, there was a difference at the time of movement, and a clear difference emerged in the success and failure in this study. Also, in the E.O.G in the up-down direction, a movement during failure showed a pattern of down direction in most cases; thus, it is deemed to affect the failure. Therefore, the kinetic postural control and E.O.G are supposed to affect the success and failure in a landing, which is the most importantly evaluated movement on the balance beam, in mutual association.
