■Background Overall prevalence of visual field loss after stroke was estimated at 31%, ranged from 5.5- 57%. Among them, homonymous hemianopia is the most common symptom of post-stroke visual field loss and leads to a decrease in the quality of life and therapeutic effect. However, standard treatment has not been established. ■Case report A 48-year-old male with right side homonymous hemianopia by a left occipital-parietal lobe hemorrhage was treated with Qu-Ji-Du-Huang-Wan, acupuncture and electroacupuncture for 20 days. We used confrontation visual field exam, automated perimetry and visual analog scale for evaluating symptoms. Following treatment, confrontation visual field exam and the subjective discomfort was improved. ■Conclusions The present case report suggests that combined Korean medicine treatment might be an effective treatment of post-stroke homonymous hemianopia. A number of follow up studies should be conducted to clarify the effectiveness of treatment.

Background: Although not clarified, the overall prevalence of visual field loss after stroke was estimated at 52% of stroke survivors and for visual acuity loss, at 70% of them. Among visual field loss patients after stroke, homonymous hemianopia is the most common symptom. Visual defect degrades the quality of life by disrupting independent life and affecting the survival of the patients, but highly-evidenced treatment has not been found until now. ■Case report A 51-year-old female with left-side homonymous hemianopia and central vision loss by a right occipital-temporal hemorrhage was treated with Hyeolbuchukeo-tang, Ikgibohyeol-tang, acupuncture, electroacupuncture, and moxibustion. We used a confrontation visual field exam, automated perimetry and visual analog scale, and visual acuity test to observe changes in the patient's symptoms and evaluate the efficacy of the treatment. After 61 days of such interventions, the patient's subjective discomfort lessened, followed by positive changes in the scales of tests mentioned above. ■Conclusion This case suggests that combined Korean medicine treatment might be an effective tool for treating post-stroke homonymous hemianopia and central vision loss. More studies should be conducted to support the effectiveness of the treatment.

Purpose: It is investigated whether the time division system can extend the field without diplopia for people with homonymous hemianopia. Methods: The time division system was manufactured by a modified mini fan and a black cardboard. In order to verify the effectiveness of the equipment, subjects with and without the equipment took part in the experiment to bisect the space and to recognize letters. Results: Subjects with and without the equipment showed +8.91 and +18.14 degrees in the experiment to bisect the space. In the experiment reading the letters and numbers with the equipment, there were 9 percentage point increase in $4{\times}4$ charts and 15 percentage point increase in $6{\times}6$ charts. It turned out that there was a remarkable improvement for the worst group for reading the charts. Conclusions: The time division system is effective in the mobility and orientation for people with homonymous hemianopia.

■ Background Patients with posterior cerebral artery infarction could complain of visual field defects or prosopagnosia that does not recognize a person's face. However, there has been no standardized treatment for these symptoms. ■ Case report A 57-year-old male patient complained homonymous hemianopia and prosopagnosia after posterior cerebral artery infarction. After combined Korean medicine treatment for 49 days, subjective visual field was improved and the discomfort associated with visual field defect and the disability of recognizing people was decreased. Evaluations were took place by assessing visual field using Automated Perimetry and Confrontation visual field exam. Discomfort caused by visual field defects or prosopagnosia was evaluated by visual analog scale. The patient was treated with acupuncture, moxibustion, and herbal medications. ■ Conclusion The present case report suggests that combined Korean medicine treatment might be effective to resolution of homonymous hemianopia and prosopagnosia after stroke.

Objective: This study presents a case of a 56-year-old Korean male with right-side hemianopia due to stroke. Homonymous hemianopia represents a visual field defect related to loss of vision in all or part of the left or right visual field in both eyes; treatment options for this condition are limited.Method: The patient was treated with acupuncture, moxibustion, herbal medicine (Yangguksanhwa-tang), and electroacupuncture around the eyes. We executed a confrontation visual field exam (the Donders test) to evaluate any visual field defectsResults: The visual field area showed improvement after the management of traditional Korean medical treatments.Conclusion: Based on this case, traditional Korean medical treatments may be effective in treating hemianopia due to stroke.
