The sense of vision is the primary means by which we gather information from our surroundings, and vision loss, therefore, severely compromises the life of the affected individuals, their families, and society. Loss of vision becomes more frequent with age, and diabetic retinopathy, age-related macular degeneration, cataracts, and glaucoma are the major causes of vision impairment. To find active pharmacological compounds that might prevent or ameliorate the vision-threatening eye diseases, numerous studies have been performed, and some botanical compounds, including those extracted from ginseng, have been shown to possess beneficial effects in the treatment or prevention of common ocular diseases. In this review, we summarize the recent reports investigating the therapeutic effects of ginseng and ginsenosides on diverse ocular diseases and discuss their therapeutic potential.

People have experienced physical problems including vision problems with aging; some are normal and some are abnormal. When they have abnormal and impaired vision, they have a lower level of life satisfaction than their sighted peers. For the elderly with sight loss, well-designed housing could be an important indicator for their quality of life. Housing adjustment and modification could help the elderly cope with sight loss, do daily activities more independently, and lead to better quality of life. The purpose of this study is to investigate housing conditions for the elderly with vision impaired, state of housing adjustment or modifications, and the effects of housing conditions on the wellness of the elderly in Korea. For this study, 18 housing cases were investigated and a total number of 65 visually impaired people aged over 55 participated. Housing condition of those participated was poor. Most observed home hazards are level differences in living areas, obstacles in the hallway, confined space that is not allowed structural modification, swing doors from wardrobe or cabinets, color contrast, poor lightings, and etc. Majority of households participated in this study did not make modification or refurbishments, rather many of them tend to adapt themselves to their residential environments. Older adults living in better housing condition and under less difficult environments are likely to have higher life satisfaction. The effects of housing condition on wellness could be more influential when individual capabilities (e.g. health condition) are weaker. The findings underline that with intervention of individual characteristics, the effects of housing and physical environment on negative outcomes of vision loss would get ameliorated or reduced.

These studies were performed to investigate the complications affecting the vision after extracapsular lens extraction(ECE), the effects of an I/A (irrigation & aspiration)device and a viscoelastic material used on the vision, the occurrence of complications and the effective corneal incision method to reduce the corneal opacity in dogs. ECE was performed bilaterally with 3 different methods using clinically normal twele mixed dogs; the method in which I/A device and viscoelastic material were not used, the method in which I/A device was used but viscoelastic material not, and the method in which I/A device and viscoelastic material were used. Postoperative complications were observed as followed; conjunctival injection, uveitis, corneal opacity due to endothelial cell loss, hyphemia, remnants of lens cortex, vitreous loss, synechia and capsular opacity. Preservation rate of vision was lower significantly in the cases showing signs of synechia, capsular opacity, or remnants of lens cortex than the cases not showing the above signs(p<0.01). There were significant reduction of the complications such as corneal opacity, clot in anterior chamber in the group using I/A device compared to the group in which I/A device was not used(p<0.01). Groups using I/A device showed slightly higher vision than the group not using I/A device (75%; 42%). There were no significant differences in the occurrence rate of complications and the preservative rate of vision between the groups with and without viscoelastic material. The present study indicated that the postoperative complications of posterior synechia, capsular opacity, uveitis and vistreous loss were important factors affecting the vision and that I/A device was applicable to extract the lens cortex and effective to elevate the success rate after ECE in dogs.

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.

Retrobulbar hematoma can arise from orbital trauma and periorbital or intraorbital procedures, and it can result in several morbidities including vision loss. Making the immediate diagnosis and performing decompression of the retrobulbar hematoma are crucial for preventing serious morbidities such as permanent vision loss. We present here a case of temporary vision loss that was due to iatrogenic retrobulbar hematoma in a patient who received infraorbital nerve block for the treatment of trigeminal neuralgia. A 70-year-old woman with trigeminal neuralgia was treated with infraorbital nerve block. Just after the procedure she experienced acute periorbital swelling, proptosis and worsening visual acuity. Immediate orbital computed tomography was done, and this revealed a retrobulbar hematoma. The patient underwent lateral canthotomy with cantholysis and administration of dexamethasone and mannitol. Improvement of visual acuity began 3 hours after these procedures. Her visual acuity was greatly improved 12 days after admission.

Blepharoplasty is one of the most commonly performed aesthetic procedures. Surgical complications are rare, but can have severe consequences, such as permanent vision loss. In this report, we describe a patient who developed primary angle-closure glaucoma (ACG) with associated vision loss after a oculoplastic procedure using local anesthesia. So far, six similar cases have been described in the literature. It is believed that acute ACG is triggered by the surgical procedure in patients with predisposing risk factors such as a cataract. Surgical triggering factors include the use of buffered lidocaine/xylocaine with adrenaline/epinephrine, stress, and coverage of the eyes postoperatively. Due to postoperative analgesic use, the clinical presentation can be mild and atypical, leading to a significant diagnostic delay. Acute ACG should therefore be excluded in each patient with postoperative complaints by assessing pupillary reactions. If a fixed mid-wide pupil is observed in an ophthalmologic examination, an immediate ophthalmology referral is warranted. Surgeons should be aware of this rare complication in order to offer treatment at an early stage and to minimize the chance of irreversible vision loss.

This paper examines the efficiency of the application of conventional and insulated gang forms for curing and protection of concrete by comparing the amount of electric energy required therefor. In addition, a thermal vision camera was used to identify heat loss from surfaces of the gang forms after each placement of concrete. Experimental results, show that the heat loss at the submerged temperature was large at the submerged surface due to the large calorific value at the surface of the mold. The insulated gang form had some heat loss in the horizontal bars. In the case of adiabatic reforming, the pattern shows a constant calorific value over time. In conclusion, the insulation performance is better than that of general gang form.

Total eyelid defect comprises full-thickness loss of both upper and lower eyelids in a patient. It is a rare and devastating condition with serious implications related to vision, which mandates early and functional reconstruction when associated with intact globe. The primary goal is to give a stable coverage for orbital protection but at the same time provide a functional reconstruction of the defect, to allow for adequate mobility of the eyelids so that the patient's vision is restored to normal with minimal disability. When the defect is massive, and in the absence of loco-regional flaps, microvascular tissue transfer is needed. In this report we describe a radial-artery-based microvascular tissue transfer with a unique innovation utilizing the contralateral frontalis muscle to reconstruct a case of unilateral total upper and lower eyelid loss.

이 연구는 산업장에서 색각이상과 관련된 유기용제 폭로근로자들에서 후천성으로 발생할 수 있는 색각이상을 정성적이고 정량적으로 평가하고 색각이상에 영향을 미치는 요인을 조사하고자 저농도의 유기용제 폭로근로자 70명과 대조군 47명을 대상으로 실시하였다. 한식 이중 15색상 배열 검사기를 이용한 색각이상을 평가한 결과 색상배열의 착오 비율과 정량적으로 산출한 색 혼란지수는 유기용제 폭로군과 대조군간 차이가 없었다. 색 혼란지수와 연령과의 선형관계는 두 군 모두에서 연령이 증가할수록 색 혼란지수가 유의하게 증가하였으며(p<0.05), 각 연령군별로 층화한 색 혼란지수의 중앙값은 폭로군이 대조군보다 높게 나타났으나 29세이하 연령군에서만 통계학적으로 유의하였다. 15색상 배열검사의 배열형태에 따라 분류한 색각이상의 유병률은 두 군 모두에서 21%로 차이가 없었으며 색 혼란지수에 대해 연령, 흡연, 음주상태 및 유기용제 폭로유무를 독립변수로 하여 다중회귀분석을 실시한 결과 연령이 유의한 변수로 나타났다(p<0.05). 이상의 결과로는 유기용제 폭로와 색각이상 발생과의 관련성을 제시할 수 없으며, 추후 색각이상 평가를 위한 색상배열 검사의 표준환경 설정, 유기용제 폭로 근로자들의 개개인의 폭로정도 평가, 그리고 색각이상 검사결과를 정확하게 분류하는 기준 등에 대한 연구가 필요할 것이라고 생각되며, 또한 저농도의 유기용제에 폭로되는 근로자들의 색각이상의 평가는 정성적이고 정량적인 방법을 통한 평가가 바람직하며 일시적인 평가보다는 추적관찰을 통한 정량적인 지수의 변화를 관찰해야 할 것으로 생각된다.
