OBJECTIVE: To observe clinical effect of acupuncture combined with conventional visual stimulation on cerebral visual impairment (CVI) in children aged 3-10 years and influence on the pattern visual evoked potential (P-VEP). METHODS: A total of 60 cases of children aged 3-10 years with CVI were randomly divided into an observation group and a control group, 30 cases in each group. The children in the control group received conventional visual stimulation therapy, 1 month as a course of treatment. On the basis of the control group, the children in the observation group was treated with acupuncture at Baihui (GV 20), Jingming (BL 1), Taiyang (EX-HN 5), Sibai (ST 2), etc. 3 times a week, and the treatment was given 4 weeks continuously as a course. Both groups received 3 courses of treatment. The visual acuity and P-VEP improvement were compared between the two groups before and after treatment. RESULTS: After treatment, the incubation period (P100-L) of the two groups was shorter than before treatment, and the amplitude (P100-A) was higher than before treatment ( CONCLUSION Acupuncture combined with conventional visual stimulation can improve the incubation period (P100-L) and amplitude (P100-A) of P-VEP in children with CVI, and improve the best corrected visual acuity in children, the clinical effect is better than the conventional visual stimulation alone.

BACKGROUND: We assessed the effects of customized in-hospital, in-person education provided by an education-specialized nurse in ischemic stroke patients. METHODS: All ischemic stroke patients who were hospitalized between April 2015 and December 2015 were included. They were provided with education about stroke by an education-specialized nurse during their hospital stay. The knowledge of stroke warning signs and appropriate responses was examined both before the in-hospital education and 3 months after discharge in 127 patients. RESULTS: The awareness of the following stroke warning signs increased significantly at 3 months after discharge compared to before receiving the education (all p values <0.001): sudden difficulty in speaking or in understanding speech (74.0→93.7%), sudden numbness or weakness (72.4→92.1%), sudden dizziness (71.7→89.8%), sudden severe headache (44.9→82.7%), and sudden visual impairment (38.6→69.3%). The proportion of patients with a good knowledge of stroke warning signs (defined as providing at least five correct answers) increased significantly, from 38.6% to 81.9%. Almost half of them (46.5%) correctly answered that they should call an ambulance first when someone shows stroke symptoms before receiving the education, with this proportion increasing to 68.5% at 3 months after discharge (p<0.001). The proportions of patients who understood the need for prompt treatment of stroke and the golden time window increased from 80.3% to 96.9% and from 66.1% to 86.6%, respectively (both p<0.001). The proportion of patients with knowledge of thrombolytic therapy for stroke also increased significantly after the in-hospital education, from 11.0% to 76.4% (p<0.001). CONCLUSIONS: In-hospital, in-person education was effective at increasing the understanding that patients have of stroke, even at 3 months after discharge. In-hospital education provided by an education-specialized nurse would be an effective intervention for increasing the likelihood of stroke patients reacting appropriately to stroke recurrence.

PURPOSE: To discriminate the visual symptoms and signs of Meares-Irlen syndrome (MIS) and nonspecific dyslexia from other ophthalmologic diseases (NODs). METHODS: Forty-five patients were enrolled. Thirty four of the patients with MIS whose symptoms improved with tinted lenses comprised MIS group. The other 11 patients whose reading difficulty improved with other ocular therapy and did not require tinted lenses comprised NODs group. The main symptoms causing dyslexia and associated ocular diseases were evaluated. RESULTS: The mean age was 17.9 +/- 9.5 years in MIS group, and 19.3 +/- 11.0 years in NODs group. In MIS group, the most common symptoms while reading were difficulty to move lines (85%), doubling (53%), and difficulty in bright condition (27%). On the other hand, blurring was the most common symptom in NODs group (45%). The associated ocular diseases in the two groups were refractive error (79% and 73%), dry eye (29% and 18%), and exophoria (6% and 27%), respectively. CONCLUSIONS: Doubling, difficulty to move lines, and difficulty in bright condition while reading are main specific symptoms in MIS compared to nonspecific dyslexia from other ophthalmologic disorders.

INTRODUCTIONUsing artificial means to treat extreme vision impairment has come closer to reality during the past few decades. The goal of this research has been to create an implantable medical device that provides useful vision for those patients who are left with no alternatives. Analogous to the cochlear implants for some forms of hearing loss, these devices could restore useful vision by converting visual information into patterns of electrical stimulation that excite the remaining viable inner retinal neurons in patients with retinitis pigmentosa or age-related macular degeneration.

METHODSData for this review were selected through a comprehensive literature search.

RESULTSAdvances in microtechnology have facilitated the development of a variety of prostheses that can be implanted in the visual cortex, around the optic nerve, or in the eye. Some of these approaches have shown the promise of providing useful visual input to patients with visual impairments.

CONCLUSIONWhile the development of various retinal prostheses have shown promise in limited clinical trials, there are distinct advantages and disadvantages for each type of prosthesis. This review will focus primarily on the Epiretinal Intraocular Retinal Prosthesis, studied by our group, but will also briefly review other modalities: the subretinal prosthesis, cortical prosthesis, and optic nerve prosthesis.

Gastric cancer with double metastasis to the orbit and duodenum is extremely rare. We report the case of a patient with gastric adenocarcinoma who presented with synchronous orbital and duodenal metastases at the time of initial diagnosis. A 60-year-old man presented with a 1-month history of visual disorder and pain in his right eye. He underwent ophthalmological examinations. The biopsy results suggested intraocular metastatic carcinoma. We conducted a systemic evaluation to identify primary malignancy. Finally, a diagnosis of advanced gastric adenocarcinoma with multi-organ metastasis was made. He planned to be treated with systemic chemotherapy.

PURPOSE: Patients with brain damage suffer from limitations in performing the activities of daily living (ADL) because of their motor function and visual perception impairment. The aim of this study was to help improve the motor function and visual perception ability of patients with brain damage by providing them with virtual reality-based contents. The usability results of the patients and specialists group were also evaluated. METHODS: The ADL contents consisted of living room, kitchen, veranda, and convenience store, similar to a real home environment, and these were organized by a rehabilitation specialist (e.g., neurologist, physiotherapist, and occupational therapist). The contents consisted of tasks, such as turning on the living room lights, organizing the drawers, organizing the kitchen, watering the plants on the veranda, and buying products at convenience stores. To evaluate the usability of the virtual reality-based visual cognitive rehabilitation service, general elderly subjects (n=11), stroke patients (n=7), stroke patients with visual impairment (n=4), and rehabilitation specialists (n=11) were selected. The questionnaires were distributed to the subjects who were using the service, and the subjective satisfaction of individual users was obtained as data. The data were analyzed using SPSS 21.0 software. The general characteristics of the users and the evaluation scores of the experts were analyzed using descriptive statistics. RESULTS: The usability test result of this study showed that the mean value of the questionnaire related to content understanding and difficulty was high, between 4–5 points. CONCLUSION: The virtual reality rehabilitation service of this study is an efficient service that can improve the function, interest, and motivation of stroke patients.

PURPOSE: To report a case of bilateral adrenal gland lymphoma mimicking symptoms of Vogt-Koyanagi-Harada syndrome. CASE SUMMARY: A 57-year-old woman complained of decreased visual acuity and metamorphopsia in both eyes. She had no prior medical history, but had experienced headaches in the past week. Fundus examination revealed multiple serous retinal detachment. Fluorescein angiography of the fundus revealed multiple pinpoint leaks in early stages and subretinal dye pooling in the retinal detachment area in late stages. The most likely diagnosis was therefore Vogt-Koyanagi-Harada syndrome. Two days later, mild fever developed and a systemic evaluation was performed. Computed tomography of chest and abdomen showed bilateral adrenal gland T-cell lymphoma. Through prompt combination chemotherapy, the patient's systemic condition recovered, and her fundus recovered with improved visual acuity. CONCLUSIONS: We experienced a rare case of bilateral adrenal lymphoma which masqueraded as Vogt-Koyanagi-Harada syndrome. When there are systemic symptoms such as mild fever and headaches, systemic evaluation should be done so as not to miss more serious systemic pathology.

PURPOSE: Periocular carbon dioxide ultrapulsed laser surgery can induce ocular damage. Herein we report a rare case of corneal burn after carbon dioxide ultrapulsed laser for nevus removal. CASE SUMMARY: A 25-year-old female patient presented with ocular pain, decreased visual acuity, and metamorphopsia in the left eye after laser surgery for nevus removal at a dermatology clinic 4 days prior. The patient's best corrected visual acuity in the left eye was 20/100. Central corneal haziness and corneal epithelial defect were observed on biomicroscopic examination. Antibiotics, steroid and artificial tear eye drops were administered for treatment. Glasses were prescribed to correct refraction errors. After 2 months of treatment, the best corrected visual acuity in the left eye recovered to 20/50, and corneal epithelial defect was mostly healed, however corneal haziness remained. CONCLUSIONS: Carbon dioxide ultrapulsed laser is commonly used in dermatological treatments. The use of an eye shield is important during this procedure, and possibility of ocular surface damage from laser treatment should be considered.
