The purpose of this case study is to present a case of oculolmotor nerve palsy due to midbrain infarction improved by acupuncture and herb medicine. Oculomotor nerve palsy is a disorder associated with dysfunction in the third cranial nerve, which causes eye movement disorder, diplopia and ptosis. The patient, who was diagnosed with Benedikt's Syndrome(Red Nucleus Syndrome), was given oriental medical treatment. Benetikt's Syndrome has the various symptoms of weakness on one side(contralateral) and eye movement disorder, ptosis, diplopia(ipsilateral) etc., but research on Benetikt's Syndrome or midbrain infarction is scant. Results of this study suggest a role for conservative therapy with herb medicine and acupuncture to treat oculomotor nerve palsy(eye movement disorder, ptosis, diplopia, etc., ipsilateral) and right motor weakness(contralateral) due to midbrain infarction. Further research into oriental medical treatment for such disorders will be forthcoming.

Recurrence of peripheral nerve palsy is unusual, specially in eye. So there's seldom report about recurrent peripheral nerve palsy in eye. We treated a patient who had consecutive oculomotor nerve palsy after recovery of abducent nerve palsy at right eye. The patient visited our clinic for abducent nerve palsy. When he was hospitalized, ophthalmalgia was VAS 4 but it disappeared when he discharged on 21th of June. Although there was, in the case of abduction of eye, no noticeable change during the hospitalization, it was healed after he received outpatient service twice a week until Nov. 3rd. Oculomotor nerve palsy appeared on 24th of November, 2008 and the patient was hospitalized on Nov. 26th. At that time ophthalmalgia was VAS 4, but disappeared when he discharged. When he entered hospital, the length between upper & lower eyelid and MRD 1 were all 0mm. However, when he discharged, the length between upper & lower eyelid was 11mm, and MRD 1, 4mm which were the same lengths as those of the normal left eye. In the case of eye movement, the motion of supraduction, infraduction, and adduction was entirely inhibited when the patient was hospitalized. By the time of discharge, the inhibition of infraduction was recovered after that of adduction, but the inhibition of supraduction was not recovered. This is a very rare case of peripheral nerve palsy, nevertheless he recovered complete twice by acupuncture and herb medicine therapy.

Giant cell arteritis, which is also referred to as temporal arteritis, is defined as a systemic vasculitis in individuals over 50 years of age. Here, we report a case of giant cell arteritis combined with oculomotor nerve palsy. An 81-year old female patient experienced a headache for 10 days in her left temporoparietal area, that was characterized by a continuous dull ache and heaviness with intermittent shooting and lancinating pain. Her symptoms persisted in spite of receiving strong analgesics in another hospital. Upon physical examination, she was found to have marked tenderness over the left temporal area, especially along the path of the temporal artery as well as limitation of adduction, supraduction and infraduction of the left eyeball. At the time of admission, her erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were 52 mm/hr and 3.94 mg/dl. In addition her brain MRI revealed no specific findings. Giant cell arteritis was suspected based on the clinical symptoms and signs as well as the elevated ESR and CRP. Oral steroid therapy started was started with an initial dose of 40 mg of prednisolone per day that was gradually tapered to 5 mg a day for 2 weeks. Her headache subsided one day after the steroid therapy and oculomotor nerve palsy was markedly improved after 2 weeks of the therapy. After 2 months she had recovered completely from her symptoms.

This study aims to report a case of oculomotor nerve palsy with mydriasis improved by Sa-Am acupuncture (大腸正格). The patient visited our clinic due to Right oculomotor nerve palsy with symptoms such as periocular pain, diplopia, vertigo, ptosis, eye adduction disorder, and mydriasis on November 11th, 2019. For the treatment, Sa-Am acupuncture (大腸正格) which used to give a significant effect on eye diseases and headaches and to remove toxins from the body was performed every time the patient visited the clinic. About a month after the treatment, ptosis disappeared, and eye adduction disorder also changed from -2 to 2 points, showing a significant improvement. Subjective symptoms such as vertigo, diplopia, and eye pain also significantly decreased from 13 to 4 points. At the second month of treatment, the eye adduction disorder improved to a normal level, and subjective ocular discomforts disappeared. The pupil size decreased from 5 mm to 2.5 mm. After 3-4 months from the start of treatment, most of the symptoms including the light reflex returned to normal. After a total of 32 acupunctures treatment, subjective symptoms such as periocular pain, diplopia and vertigo, as well as ptosis and eye adduction disorder disappeared, and the pupil size, including the light reflex, also improved to the normal level.

In this paper, Band-limlted Gaussian Random Noise and PRBS(pseudo random hinary sequence) are used as a test signals to estimate the dynamic characteristics of the ocuiomotor system. Eye movements of the human subject are measured by E.O.G(electro-oculography) and the control characteristics of the oculomotor system are studied by random signal an-alysis based on the statistical communication theory. The conclusions are summerized as follows. (1) From the frequency response, the gain curve rises slightly at the regions of 0.7~0.9 Hz and 1.8~2 Hz due to the saccades which are occurred during usual tracking. (2) The average rate of information transfer by the oculomotor control system is 1.24 bits/sec, being calculated from the power spectral density and the cross spectral density for the Gaussian random input.

Strabismus refers to a extra-ocular muscle imbalance that results in improper alignment of the visual axes of two eyes. It may be divided into paralytic and non-paralytic strabismus. Paralytic strabismus is primarily a neurological problem: non-paralytic strabismus is more strictly an ophthalmologic problem. This case report focuses on paralytic strabismus resulting from palsies of the third and the sixth cranial nerves, respectively. Oculomotor nerve palsies result in binocular diplopia with characteristic patterns of strabismus. Oculomotor nerve provides motor and parasympathetic innervation to the eyes. Acquired oculomotor nerve palsies are not uncommon. Injury to the third nerve may result in complete or partial dysfunction. Complete third nerve palsy is manifested by ptosis, dilated pupil, an eye that is deviated down and out in primary position, and limited adduction, elevation, and depression. Patients with unilateral sixth nerve palsy complain of binocular, horizontal diplopia esotropia in the primary position due to unopposed action of the medial rectus and limitation of abduction due to weakness of the lateral rectus. Diplopia is worse in the direction of the paretic lateral rectus muscle. Paralytic strabismus are treated, based on the theory of Oriental medicine. with berbal medicines having gun-bi(健脾), bae-to(培土), gue-pung(祛風) effect of acupuncture around the eyes and etc. We describe a 63-year-old woman with complete the 3rd cranial nerve palsy and a 32-year-old woman with the unilateral 6th cranial nerve palsy who treated with acupuncture and herbal medicines and showed complete recovery.

The aim of this study is to report the effectiveness of a traditional Korean medicine treatment for oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage. A 54-year-old male patient with oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage after a traffic accident was treated with Korean medicine, including acupuncture, electroacupuncture, sweet bee venom pharmacoacupuction, moxibustion, and herbal medicine. The effect of treatment on symptoms - ptosis, and eye movement - was evaluated using a ratio of eye opening and eye movement between the paralyzed eye and the normal eye. After 41 days of treatment, the clinical symptoms had improved. The ptosis and eye movement started to show improvement from day 20; at the time of discharge, ptosis had improved by more than 50%, and eye movement showed some improvement as well. This study suggests that Korean medicine may be an effective treatment for oculomotor nerve palsy induced by traumatic subarachnoid hemorrhage.

In this paper, we measured the tracking response time of horizontal eye movement to the target moving according to the square waveform to investigate the predictive characteristics of the human oculomotor system. And in the experiment we used the square waves with an amplitude of 5 degree and frequencies o.1, 0.2, 0.4, 0.6, 0.8, 1.0, and 1.2 Hz. Random occurrences of the human eye movement reponse time were analyzed using a finite Markov chain process and we found the results as follows. From both the experimental and theoretical results, we found the trend showing that Predictive characteristics moved from the transient state to the steady state.

The purpose of this study is to propose and to apply new Revised Simulator Sickness Questionnaire(RSSQ) that is effective quantification tool by revising and complementing SSQ because Simulator Sickness Questionnaire(SSQ), which is being used generally to quantify Simulator Sickness has several problems. For this study, we reduced 31 symptoms that are related to Simulator Sickness to 22 symptoms and derived weighting for each other from 15 experts. We developed new RSSQ with 22 symptoms and implemented factor analysis by using 142 RSSQ which is questioned before and after getting on simulator. It was classified to four major symptom groups as the result of the factor analysis. They are Disorientation, Oculomotor, Nausea, and Confuse. The scoring system of RSSQ provides subscales score of Disorientation, Oculomotor, Nausea, and Confuse as well as total severity. The scoring system of RSSQ which is proposed by this study is expected to improve accuracy of measure compared with an existing scoring system of SSQ, and to contribute with understanding the effect of Simulator Sickness more adequately and clearly.

This study describes the battery functional test in order to explore vestibular oculomotor system. These tests are the following : a) acceleration test by using a pseudorandom stimulus. b) caloric test by considering both the constant temperature variation in the semicircular canals for a short time and the only head movement, to the fore and the back, for the ear ir- rigation, which gave us two types of stimulus (cold and warm) according to the only head position. c) optokinetic test by continuous constant velocity displacement of a large image fill- ing the entire subject's visual field. With relation to the clinical practices, some results of research programs which are at present in progress are presented.
