5 cases of cortical blindness

Male, 70 years _ because of 2 days blind admission, previous history of diabetes, high blood pressure years. Examination: 3p20/15kPa, language Ming Shen Qing,[link widoczny dla zalogowanych], eyes blind, double-pupil so too with the round, there is light reflection, eyes light perception, the left limb is weak. Normal tendon reflexes, muscle tension exists t t pathological reflex (±). Head CT showed bilateral occipital lobe infarction. Fundus examination: optic disc boundaries clear. Highly reflective AtV = 1t3. Example 5: Patient male, 54 years; for blind and 3 days in 1994 lo 11 hospitalized patients before admission to the hospital in Changchun and eye treatment, excluding the head CT scan showed the eye disease, bilateral occipital lobe infarction. Admission examination: BplS/10kPa, Ming Shen Qing language, such as Datong double round pupil, light reflex present. Vision eyes that move. Limb strength and muscular strength were normal, there is knee tendon reflexes, pathological reflexes elicited. No abnormal cardiopulmonary abdomen. Ask medical history, past health, alcohol addiction usually l ~ 2 kg / day drinker, year in and year 2 to discuss the group of patients were acute onset cortical blindness, to almost force the main barriers to disease, blindness, 2 down, depending on the material is unclear 2 cases. With pure hemianopia hemianopsia in 1. Han misdiagnosed eye diseases in which 2 cases. Above all by the head CT scan is indeed the cortical blindness. Cortical blindness often wake up in the brain artery spasm or occlusion of large branches due. Bilateral occipital lobe in the adjacent anatomical widow big move after bilateral basilar artery root issue. The easy interaction between hemodynamic changes in clinical temporal occipital lobe infarction in 1 case on the large area of cortical blindness may also occur in 5 cases in this group are associated with this for 2 to 3 weeks. After a vasodilator, activation of brain cells and improve brain blood transport and better, but still left unclear, as the object observed by this group of patients to visual impairment as the first symptom of cerebral vascular occipital lesions. In the case of investment and a CT misdiagnosed as eye diseases. Can not find it in the eye of the visually impaired to do as soon as the end of CT Kan Li Shuying Wang Jin Li Zili J · 25 - in our hospital from l992 to 1995 fell on 38 patients with severe muscular fatigue as treatment and follow-up were obtained satisfied with the results reported below. 1 Division of Clinical Information Select complained of severe visual fatigue, the iliac anterior segment, retina, glaucoma, nervous system disorders. Anisometropic eyes were 2.5D, refractive correction by the mirror after wearing. Still can not relieve the symptoms of 38 patients as the observed object (including uncle l6, female 22 cases). Age of 11 years to 57 years, the average age of 41.7 years. n ~ l5 years of age 3 down l20 ~ 29 years old in 6 cases '3 o ~ 39 years of age in 9 patients l4o ~ 49 years old in 15 cases; 5o ~ 57 years in 5 cases. 2 column search method ① visual acuity test; ② refractive eye fundus examination f @; ④ binocular function tests; @ accommodative vergence and adjust the ratio. (AC / A) check back for the addition to l 2 / D, the remainder are low. 3 of them down to 0 / D. o ~ 1 / D accounted for 3.1 97.37.3 treatment follow-up treatment Yuan fell open to the 36 patients with refractive lens in the past, the eyes or one eye inward increase with the end of the prism in order to eliminate the minimum degree prism symptoms prevail. The continuous reading l ~ 2 hours later, a clear sense of comfort, then prescription glasses. Prism required for this group of 2 to 8, namely, when corrected by looking outside the implicit slope near 1 / 4 in 4 cases, 1 / 3 of the l0 down, l, 2 are n down, 2 / 3, 4 down. 3 / 3, 4 down. 3 down into account pro-phoria phoria no investigation, but with a shaded display intermittent exotropia, still given to the lowest degree of elimination of symptoms. Down in the two phoria patients, the line l at the end of the outward prism binocular treatment. 3.2 The effect of love followed after wearing prism. 38 cases, as the myopia material Jing Xi, symptoms disappeared and were followed up for 3 years u stomach, with an average follow-up time 1 and a half years. Can persist in reading, 1 case of leave of absence for this purpose the students have been back to school. After only two cases a year outside the implicit gradient increased. Fork feel as tired. 1 case of the original 4 to 6. Another 1 case the original 2 to 5 and 22 cases in which implicit gradient. Scope and financial Taiwan AC / A for review, the changes were not statistically significant difference in 4 to discuss Department of muscular asthenopia usually caused by extraocular muscle imbalance. Common reason for exophoria and financial units within the weak. Regulation and vergence imbalance or separation, patients often complained of press time can not be sustained. As the gap, eye pain, headache, double vision, nausea. In severe cases, can not continue to study and work. 38 cases of this 50 years old 30 years old in the majority of applications, 30 of which close down are doing the work. Professors, scientific research, engineering, financial desk staff, students. Their corrected visual acuity is good, but when the helmet look like holding another recent serious. Can not be sustained. Even serious enough to not smell read We have therefore had a job change to show proof of medical boil. Since the use of prism treatment. Have achieved good results. Therefore I believe that the prism
