Atorvastatin is one of the most widely prescribed medications for dyslipidemia treatment. In Korea, post combined therapy with ezetimibe, a 73-year-old woman was reported by a community pharmacy to have experienced visual field defect, which recovered after drug discontinuation. She had never experienced this symptom before, and several studies have reported an association between use of statins and visual disorders such as blurred vision, diplopia, and cataract. Blockage of cholesterol accumulation, oxidative stress, or myopathy is expected to be a cause of this symptom. Naranjo scale, Korean causality assessment algorithm (Ver.2), and World Health Organization-Uppsala Monitoring Center (WHO-UMC) criteria were the three tools used to determine causality between the visual disorder and atorvastatin. The results represent 'probable', 'certain', and 'probable/likely' causality, respectively. Our results, in combination with a review of literature, indicate that ocular adverse effects are highly likely related to atorvastatin.

Extremely massive sellar xanthogranuloma (XG) are rare, and the surgical outcome and prognosis are not well known. XG remain unknown whether they are derived from Rathke's cleft cysts (RCCs) or craniopharyngiomas (CPs) following extensive inflammation and metaplasia, to the point that no epithelium is readily identifiable. These lesions usually tend to occur in younger patients (mean 28.3 years), have a smaller diameter, and remain primarily intrasellar region with infrequent calcification. This 36-year-old man presented our hospital with visual deterioration. At the time of visit, there were no neurological problems other than visual field defect and hormonal disorder. He visited our hospital in 2007 due to headache and decreased vision, and underwent transphenoid surgery for pituitary RCC. Since then, he has received treatment at our hospital for postoperative hormonal disorders. Through preoperative imaging study, the author suspected CP and underwent surgery. During the operation, the adhesion of the tumor to the surrounding major neurovascular structures was severe in the naked eyes, but the tumor could be removed more easily than expected. The postoperative histological findings were confirmed as XG. The postoperative course was uneventful. Compared to the previous literature, this case is a case where the size of XG is very large in a sellar region and it can be proved that it originated from the RCC. And regular follow-up is necessary to confirm the prognosis after surgery.

Chronic progressive external ophthalmoplegia (CPEO) is a complex slowly progressive mitochondrial disorder characterized by extraocular muscle weakness with or without multisystem involvement. The mainstay of therapy in a patient with CPEO is supportive. However, in moderate cases, surgery might be indicated including surgeries for ptosis and strabismus. In this article, we report a Saudi patient with CPEO due to compound heterozygous variants in the DNA polymerase gamma (POLG) gene c.2246T>C p.(Phe749Ser) and c.1735C>T p.(Arg579Trp), which are classified as pathogenic. Proper diagnosis with genetic testing confirmation is important to guide the management and counsel the patient about the prognosis and the management options. The patient was successfully managed with bilateral frontalis sling and illustrates the importance of surgical intervention to improve vision and cosmetic appearance in patients with CPEO. We emphasize the importance of multidisciplinary care in the management of cases of mitochondriopathy, especially CPEO.

Objectives : This study investigated warning signs and stroke presymptoms and their relationship with acute stroke patients in each stroke type. Methods : 217 patients with first-ever acute stroke within 2 weeks as the case group, 146 people without four major risk factors (hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease) as the healthy control group (Normals), and 160 people as the general control group (Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from July 2005 to March 2007 for this case-control study. We analyzed the odds ratio of each warning sign or presymptom by multivariate logistic analysis and evaluated each stroke type, as well as general characteristics such as age, sex, etc. Results : Paralysis or weakness of the face and limbs, visual field disorder or loss of vision or blurred and double vision in eyes or both eyes, and sudden difficulty in speaking or dysarthria showed significant increase respectively in each stroke type. In contrast, numbness or tingling sensation or lowering sensation of the face and limbs, numbness or dead sensation of 1st and 2nd fingers, tension at cervical lesion, blepharospasm, facial spasm, etc. had no significant relation with stroke occurrence. Conclusions : In this study we demonstrated that each presymptom have an influence on each stroke type and have different odds ratio for stroke. We believe this may contribute to interpreting the importance of warning signs or presymptoms for each type of stroke, and more prospective studies are needed.

According to the Ministry of Health and Welfare, "Status of Registered Persons with Disabilities", the number of people with disabilities is 2,494,460 as of 2015. The lowest rates of children with disabilities were intellectual disabilities (23%) and mental disorders (33.3%). The highest rates of screening were blindness (97%), heart failure (94.4%), and hearing impairment (92.7%). 65.2% of visually impaired people who have already had a disability at the time of marriage, and the remaining 34.8% can be thought to be the cause of high incidence of disability after marriage. 'SID (Seed in the Dark)' project was designed to recapture the visually impaired parent's desire for attachment and the space difficulties of the blind who want to be a normal parent to their children through a visual impairment of a father with 7-year-old daughter. Using Gear VR(Virtual Reality), the general public was able to feel the surroundings as if they had no vision and focused on the hearing. Especially, We expressed the sound wave visually and added the hilarious game element which grasps the terrain of the maze by sound wave like a 'blind person who perceives the surroundings by sound' and catches up with daughter. People with disabilities who are far from mental illness often have a form of family with children. The fact that the rate of childbirth is high means that there is relatively little problem in daily life. It is wondered that the rate of blindness among the visually impaired, which accounts for 10% of the total disabled, is the highest at 97%. This is because, in the case of the visually impaired, the obstacle is often caused by aging, accidents, or diseases due to inherited causes rather than the visual disorder. In particular, However, the fact that there is an obstacle in vision that accounts for 83% of the body's sensory organs causes other difficulties in the nursing process of children who are non-disabled. Parents do not know the face of child when their visual impairment is severe. Parents are extremely anxious about worry that they will be lost or abducted if their children are not by their side. And that the child recognizes the disability of his or her parents other than the other parents easily and takes it as a deficiency. Since visually impaired parents are mentally mature parents with non-disabled people, they may want their children not to feel deprived of their disability. The number of people with visual impairments has been increasing since 2001, and people with impairments often become disabled. In addition, there is much research on the problem of nondisabled parents who have children with disabilities, while there is relatively little interest and research on the problem of nondisabled child rearing of parents with disabilities.

Purpose : The purpose of this study is to analyze the factors affecting the mental health of students in the department of optometry by the gender and to provide differentiated help to student life and career guidance. Methods : Questionnaire for 132 students in the department of optometry in Chungcheong region was analyzed and mental health was compared and analyzed by the gender. In this study, a questionnaire by SCL-90-R was used, and all statistical information was statistically processed with a significance level of p<0.05 using SPSS 18.0 (SPSS 18.0 was used for processing statistical information with a significance level of p<0.05). Results : Students of the department of optometry presented mental health problems; somatization was 22.7%, psychasthenia was 28.3% and hostility was 12.8%. Depression and paranoia were 27.7% and 10.2% respectively, followed by interpersonal sensitivity, psychosis, phobia, and anxiety disorder with 14.7%, 10.4%, 5.9% and 17.4% respectively. Conclusion : About 28.7% of the students of the department of optometry students experienced somatization, psychasthenia or hostility due to negative mental health and female students ranked relatively higher in all variables than males. Therefore, it is judged that differentiated counseling and guidance in life will be needed for students based on their gender differences.

Object:Nicotine dependence is the most common substance abuse disorder. One of the characteristics of nicotine dependence is craving. Regional activation of the brain induced by craving for nicotine was evaluated by using functional magnetic resonance imaging to investigate neuroanatomical site of smoking craving. Method:A smoker who satisfied DSM-IV criteria for nicotine dependence and a non smoker was studied. MRI data were acquired on a 1.5T Magnetom Vision Plus with a head volume coil. Two sets of visual stimuli were presented to subjects in a random manner. One was the film scenes of inducing smoking craving and the other was neutral stimuli not related to smoking. There were two fMRI sessions before and after smoking or sham smoking. Data were analyzed using SPM99. Results:fMRI showed significant activated area in anterior cingulate and medial frontal lobes in the smoker during smoking craving. Right dorsolateral prefrontal cortex and parietal lobes were activated in the control during visual stimulation before smoking. After smoking, there was no brain activation during visual stimulation in both of smoker and non smoker. Conclusion:Metabolic activity of the anterior cingulate and medial frontal lobes increased during craving for smoking. This result suggests that fMRI may be a valuable tool in the identification of neurobiological process of craving.

The neuronal ceroid-lipofuscinoses (NCLs) are a kind of neurodegenerative storage disorders. The NCLs are charecterizated by accumulation of autofluorescent lipofuscin or lipopigment in the brain. All NCL group belongs to in lysosomal storage disorders (LSDs), except Northern epilepsy. NCLs are the most common group of progressive neurodegenerative disorders in childhood, with an incidence as high as I in 12,500 live births. Four main clinical types have been described based on the onset age : infantile, late infantile, juvenile and adult types. Clinical symptoms of NCLs include loss of vision, seizures, epilepsy, progressive mental retardation and a premature death. Although mutation causes neurodegeneration in NCLs, the molecular mechanism by which mutation leads to neurodegeneration remains unclear. In this paper, we review the characteristics of these NCLs.

In developed and industrialized countries life expectancy has increased significantly over the past century. As a consequence, the proportion of elderly individuals in these countries has also enlarged with the resulting increased burden on health care providers. In many developing countries the problem of age related and other eye disorders has far outstripped the ability to manage them. Accordingly, the World Health Organization (WHO) has introduced an initiative: Vision 2020 - The Right to Sight, with the objective of eliminating preventable blindness by the year 2020. This paper reviews the broad range of conditions involving external and internal structures of the eye and also the effects of aging on visual functions. It is hoped that this will provide a stimulus for increased study of these disorders, improved clinical diagnosis, and an enhanced interest and role in contributing to the objectives of the WHO and the World Council of Optometry with respect to early diagnosis, prevention and management of the diseases and disorders of the eye that are more prevalent in old age.

Objectives: The purpose of this study is to achieve a vision for autistic children and their parents aimed at generating interest in ideas such as "Sanitas Per Aquam" (SPA), massage and music therapy, which has begun to have widespread use and to attract attention. Methods: This cross-sectional, descriptive study was carried out with autistic children and their parents from February to April 2015 in $Mu{\breve{g}}la$, Turkey. The study was began by interviewing experts in the field and by developing a suitable assessment questionnaire. In order to direct the flow of conversation between the researchers and the autisitc children and their parents, the researchers conducted semi-structured face to face interviews in a form that had been determined by using reports in the literature and the opinions of experts in the field. Results: Forty two boys (84%) and eight girls (16%) with autism participated in our study. Children in the 0 - 7 age group spent long time in the bathroom (P = 0.001). Boys liked to be hugged more than girls (P = 0.01). Children ages 0 - 7 years liked bright lighting while those 15 years of age and older liked gloomy lighting (P = 0.009). Except for these statistically significant sex- and age-related differences, no other statistically significant differences were noted in the parameters of this study. Although the result was not statistically significant, more children with mild autism disorder obeyed commands like inhale or exhale (P = 0.051). Conclusion: Treatment for autism spectrum disorders is not yet fully possible, so many studies are being done to alleviate some symptoms and to improve the quality of life for individuals with autism and their families. As a result of our study, whether touching the areas the children want touched and listening to their favorite music are required to stimulate the brain remain as questions in our minds.
