The glaucoma, cataract and causing-blindness-diseases have high clinical importance by their severity of the symptoms and possibility of causing visual loss. Glaucoma is caused by an increase in the intraocular pressure, if severe enough, can cause field loss and eventually complete blindness. In cataract, the general clarity of vision is impaired due to a loss of transparency of the chrystalline lens of the eye. The causing-blindness-diseases can be divided to PokMaeng which cause sudden blindness and ChungMaeng, in which visual acuity is losed gradually. In glaucoma, cataract and causing-blindness-diseases, the visual acuity is affected and the patient may complain blurriness, fatigue of eye, visual field loss deficiency or scintillant feeling, vitreous floaters. In this study, 32 patients who have cataract, glaucoma or other causing-blindness-diseases was treated with oriental medicine or acupuncture from July, l996 to May. 1997, and was followed up by their symptoms and visual acuity. 1. In glaucoma patients, intraocular pressure decreased significantry and the symptoms improved positively. 2. In cataract patients, there was no improvement of visual acuity but $40\%$ of patients found their symptoms improved. 3. In causing-blindness-diseases, $57\%$ of patients reported improvement of their symptoms such as blurriness or fatigue of eye. 4. Through oriental medical treatment, the symptoms of glaucoma, cataract and causing-blindness-diseases can be treated effectively. Therefore oriental management seems to be possible to cure glaucoma, cataract and causing-blindness-diseases.

Two patients, one with glioblastoma multiforme [GM] in the right thalamus and the other with meningioma at the right frontal convexity, had suffered bilateral cortical blindness after transtentorial herniation. On one of those patients, bilateral cortical blindness had occurred due to acute obstructive hydrocephalus caused by GM and on the other patient, cortical blindness had developed after acute hemorrhage from meningioma. Bilateral occipital lobes of those patients showed signal change on the brain magnetic resonance image [MRI]. There were no ophthalmologic abnormalities on fundoscopy and ophthalmologic examination. After recovery of consciousness, cortical blindness was detected in both patients, and during gradual recovery period, visual function was slowly recovered. The pattern of visual evoked potential [VEP] at 7 weeks and 12 weeks after herniation was normalized gradually. Cortical blindness due to herniation was reversible, even though the high signals of bilateral visual cortex still existed on MRI 16 month later in case 2.

Purpose: The purpose of this study is to discover the nature from the life experience of a person with unilateral acquired blindness and his/her family after losing the eyesight and adapting in the environment and to find the meaning of life and how to solve the problem in psychosocial aspect. Methods: This study uses one of the qualitative research methods which explains how families with the unilateral acquired blind perceive blindness after experiencing it and observes how they signify it. starts with interest in lifestyles of individuals and their families and tries to understand the subjective existences of participants in accessible ways and draw the experiences after becoming one-side blind. It cyclically uses deductive verification process through inductive method and establishing hypothesis using materials. Results: According to the results of this study, unilateral acquired blindness studies, due to shattered life, they did not know what to do. Also, discomfort from struggling in a big tunnel and even will to live were found. trying to go out to the world, seeing the new world, and trying to encourage myself, strong attachment to life was shown to by saying, appeared. Each includes sub-topics such as feeling abandoned after confirmed the blindness, feeling disappointed to doctors, family, and friends, trying to live with hope, struggling in a tunnel with thinking how to live, closing the mind from the world, seeing outside the world in the midst of struggling, trying to forget the past with the will of life, having hope to live with care of family, and trying to keep the rest vision. Conclusion: Firstly, in nursing aspect for their adaptation, programs for disable people and nursing intervention focused on their families should be developed. Secondly, since it can be economic and psychological burden for their families and acquaintances, it is necessary to support the blind so that they can find fitted rehabilitation programs and come back to society. Thirdly, active participation of health care providers may influence social interest the improvement of national welfare policy for the unilateral acquired blind.

A total of 423 blood samples were collected (during 2009 and 2010) from all the ram holdings at three major Jordanian governmental Awassi breeding stations (Al-Khanasry, Al- Mushairfa and Al-Fjaje) and two private flocks. All blood samples were screened for the presence of mutations at the CNGA3 gene (responsible for day blindness in Awassi sheep) using RFLP-PCR. The day blindness mutation was detected in all studied flocks. The overall allele and genotype frequencies of all studied flocks of the day blindness mutation were 0.088 and 17.49%, respectively. The genotype and allele frequencies were higher in station flocks than the farmer flocks (0.121, 24.15 and 0.012, 2.32, respectively). Al-Mushairfa and Al-Khanasry stations have the highest genotype and allele frequencies for the day blindness mutation that were 27.77, 30.00% and 0.14, 0.171, respectively. The investigated farmer flocks have low percentages (0.03, 5.88% at Al-Shoubak and 0.005 and 1.05%, at Al-Karak, respectively for genotype and allele frequencies) compared with the breeding stations. Ram culling strategy was applied throughout the genotyping period in order to gradually eradicate this newly identified day blindness mutation from Jordanian Breeding station, since they annually distribute a high percentage of improved rams to farmer's flocks.

The camouflage pattern was difficult to distinguish from the surrounding background, so it was difficult to classify the object and the background image when the color image is used as the training data of deep-learning. In this paper, we proposed a red-green color blindness image transformation method using the principle that people of red-green blindness distinguish green color better than ordinary people. Experimental results show that the camouflage soldier's recognition performance improved by proposed a deep learning model of the ensemble technique using the imitated red-green-blind image data and the original color image data.

This research was performed to examine the ratio of blindness to the child care environment and compare the evaluation of it among principals, teachers and mothers. Data were collected from questionnaires completed by respondents of this research were 37 principals, 37 teachers and 261 mothers of infants and toddlers at child care centers in Incheon, Korea. Cross tabulation, one-way ANOVA and Duncan's Multiple Range Test were utilized to analyze the data. In almost all of the items about the child care environment, mothers showed higher degrees of blindness than principals and teachers. In most of the items, mothers'evaluations were higher than those of principals and teachers. As a result, the researchers recognize a pressing need far programs far parents to improve the quality of child care.

The purpose of this study is to find the characteristics of the blindness of Sim Bongsa, Sim Cheong's father, in Sim Cheong Jeon (the story of Sim Cheong). This is one of the representative works about the filial piety in Korea. This article regards the story as the process of restoring the sight of the father and tries to examine the cause and the timing of his blindness to make its diagnosis in the psychoanalytic perspective. The predominant characteristics of Sim Bongsa were very dependent and irresponsible. He was so unqualified to be a head of a family. He sought to close his eyes toward reality in his unconsciousness. His blindness can be diagnosed as a case of psychogenic hysteria, conversion disorder. The fact that he suddenly could see when the empress turned out to be his own daughter, Cheong, can be a meaningful proof for this diagnosis. It means that his symptom of blindness disappeared when he realized a new reality which ensures a comfortable and easy-going life for himself.

The incidence of blindness after aneurysm surgery is very rare. We experienced a case of unilateral blindness after internal carotid artery[ICA] aneurysm wrapping. A 43-year-old male immediately developed ipsilateral ocular pain and visual loss in his left eye after the treatment of a lateral ICA aneurysm by wrapping with muscle pieces. He had also multiple aneurysms, which were multilobulated anterior communicating artery [A-com], middle cerebral artery[MCA] and posterior communicating artery [P-com] aneurysms. Coilings were done for a part of A-com artery aneurysm and P-com artery aneurysm on admission. The remaining A-com artery aneurysm was clipped and ICA aneurysm was wrapped with temporal muscle piece. A retrobulbar optic neuropathy might have resulted from either direct injury or damage to small dural vessels of the posterior optic nerve. Actually, the optico-carotid space was tight and the optic nerve was compressed by swollen muscle piece. Despite releasing of compression of the optic nerve on second day, his visual loss was irreversible.

This report described an outbreak of blindness caused by hypovitaminosis A in Hanwoo (Korean native cattle) in Gyeongsangbukdo province, Korea. The diagnosis was based on clinical findings, analysis of diet, and concentration of vitamin A and carotene in serum and/or feedstuff. Thirty eight of 48 cows were found to be affected. The causative diet contained higher levels of crude protein, net energy and crude fat and lower level of total fiber and crude fiber. Surprisingly, vitamin A was not detected in the causative diet. Treatment of vitamin A to Hanwoo that had blindness did not induce further progress of the symptom. Furthermore, there were no additional diseases detected. Based on the observations described above, this case was diagnosed as hypovitiminosis A.
