's experience is introduced in the treatment of cortical blindness with the comprehensive acupuncture therapy for benefiting and resolving stasis. The comprehensive therapy includes acupuncture at Sishencong (EX-HN 1), Xinming No.1 (Extra), Shang Jianming, Chengqi (ST 1), Xinming No.2 (Extra), optic area and visual area (scalp acupuncture); acupoint injection applied alternatively at Qiuhou (EX-HN 7) and Taiyang (EX-HN 5); the auricular point paste stimulation at Brain Point, Shenmen (TF), Gan (CO), Shen (CO), Yan (LO), Eye No.1 and Eye No.2; as well as the tapping therapy with skin needle at Zhengguang No.1 and Zhengguang No.2. Additionally, 3 typical cases of cortical blindness are introduced. The coordination of the different acupuncture techniques is analyzed so as to explain its actions as benefiting , resolving stasis, promoting blood circulation and nourishment of the eyes.

Group B streptococcus (GBS) is the leading cause of neonatal morbidity and mortality. Late-onset GBS disease commonly manifests as occult bacteremia or meningitis. Approximately 50% of survivors of late-onset meningitis have long-term neurologic sequelae. Cerebrovascular complications are often associated with unfavorable clinical outcomes of GBS meningitis. There have been a few reports of cerebral infarction accompanied by GBS meningitis. We report a 29-day-old girl with severe, widespread cerebral infarction due to late-onset GBS meningitis. Isolated GBS strain from this patient was serotype III, ST-19. Currently, she has cortical blindness and significant developmental delay.

Group B Streptococcus (GBS) commonly causes neonatal meningitis and sepsis. In infants with late-onset meningitis, fever, irritability or lethargy or both, poor feeding, and tachypnea are common initial signs. Major neurologic sequelae are observed in 29% of children, the most serious including global or profound mental retardation, spastic quadriplegia, cortical blindness, deafness, uncontrolled seizures, hydrocephalus, and hypothalamic dysfunction. We report a 14-day-old full-term female infant who presented with grunting and irritability to the emergency room and was diagnosed with GBS meningitis subsequently complicated with central diabetes insipidus and secondary hypopituitarism. Central diabetes insipidus should be ruled out in infants with complicated GBS meningitis.

PURPOSE: To report a case of recovery of bilateral cortical blindness in a patient with posterior reversible encephalopathy syndrome. CASE SUMMARY: A 46-year-old female visited the ophthalmology department due to abrupt visual acuity decrease. Ten days earlier, she had received conservative management due to anemia caused by menorrhagia and uterine prolapse. She underwent a gynecological operation to remove a uterine myoma two days previously, and was given a blood transfusion postoperatively because of excessive bleeding. After the transfusion, she complained of acute blurred vision. Her best corrected visual acuity (BCVA) was hand motion 10 cm in both eyes. There were no abnormal specific findings except retinal dot hemorrhage at the temporal side in the left eye on fundus examination. Her pupillary light reflex was normal and optical coherence tomography examination was unremarkable in both eyes. However, flash visual evoked potential findings showed reduced P100 amplitude in both eyes and she was diagnosed with posterior reversible encephalopathy syndrome based on brain magnetic resonance imaging. After close observation without any treatment, the symptoms gradually improved. Finally, her BCVA recovered to 1.0 and P1 and P100 amplitudes were restored to normal range in both eyes at 16 weeks from the first diagnosis. CONCLUSIONS: A patient complained of bilateral visual loss without other neurological symptoms after chronic blood loss and blood transfusion. She recovered visual acuity completely with prompt diagnosis of posterior reversible encephalopathy syndrome and close observation only.

Cerebral vasospasm associated with hyperthyroidism has not been reported to cause cerebral infarction. The case reported here is therefore the first of cerebral infarction co-existing with severe vasospasm and hyperthyroidism. A 30-year-old woman was transferred to our hospital in a stuporous state with right hemiparesis. At first, she complained of headache and dizziness. However, she had no neurological deficits or radiological abnormalities. She was diagnosed with hyperthyroidism 2 months ago, but she had discontinued the antithyroid medication herself three days ago. Magnetic resonance imaging and angiography showed cerebral infarction with severe vasospasm. Thus, chemical angioplasty using verapamil was performed two times, and antithyroid medication was administered. Follow-up angiography performed at 6 weeks demonstrated complete recovery of the vasospasm. At the 2-year clinical follow-up, she was alert with mild weakness and cortical blindness. Hyperthyroidism may influence cerebral vascular hemodynamics. Therefore, a sudden increase in the thyroid hormone levels in the clinical setting should be avoided to prevent cerebrovascular accidents. When neurological deterioration is noticed without primary cerebral parenchyma lesions, evaluation of thyroid function may be required before the symptoms occur.

BACKGROUND: Posterior cortical atrophy (PCA) is characterized by slowly progressive early onset dementia with cortical visual dysfunction and disproportionate atrophy of the posterior cortex. CASE REPORT: A 55-year-old right-handed woman developed visuo-spatial impairments that progressed rapidly into cortical blindness over the following 3 months. Neuro-psychological evaluation revealed Gerstmann syndrome and severe constructional impairments with all components of Balint syndrome. However, her memory, insight, and judgment were preserved. Her brain MRI was normal. However, 18F fluorodeoxyglucose positron emission tomography revealed a marked hypometabolism in the bilateral parieto-occipital region. CONCLUSIONS: Although rapid progression of visuo-spatial dysfunction without memory impairment occurred, we considered PCA as well.

Transient cortical blindness (TCB) is a rare but well-known complication of cerebral angiography. Its pathophysiology remains uncertain. We would like to report a case of TCB in a patient during a follow up vertebral angiogram for post-coil embolization of left posterior inferior cerebellar artery aneurysm. Patient's vision was resumed spontaneously within 24 hours after angiography, with no residual neurological deficit in subsequent clinical follow up. Multi-modality imaging evaluation including vertebral angiography, brain CT and MRI performed on same day are presented.

Arnold-Chiari malformation type III (CM III) is an extremely rare anomaly with poor prognosis. An encephalocele with brain anomalies as seen in CM II, and herniation of posterior fossa contents like the cerebellum are found in CM III. The female infant was a twin, born at 33 weeks, weighing 1.7 kg with a huge hydrocele on the craniocervical junction. After operations were performed, she was referred to the department of rehabilitation medicine for poor motor development, swallowing dysfunction, and poor eye fixation at 22 months. The child was managed with neurodevelopmental treatment, oromotor facilitation, and light perception training. After 14 months, improvement of gross motor function was observed, including more stable head control, rolling, and improvement of visual perception. CM III has been known as a condition with poor prognosis. However, with the improvement in operative techniques and intensive rehabilitations, the prognosis is more promising than ever before. Therefore, more attention must be paid to the rehabilitation issues concerning patients with CM III.

A 38-year-old man was operated with posterior spinal decompression and pedicle screw instrumentation for his L2 fracture with incomplete neurological deficit. In the recovery, he complained of blindness in both eyes after twelve hours. Computed tomographic scan and magnetic resonance angiography revealed bilateral occipital lobe infarcts. He remained permanently blind even after three years follow-up. Though rare, perioperative vision loss is a potential complication following spine surgery in prone position. We report a rare occurrence of cortical blindness following lumbar spine surgery.
