A middle-aged gentleman with history of left penetrating keratoplatsy presented with left eye perforated corneal graft secondary to infective keratitis. The affected eye was blind from absolute steroid-induced glaucoma. In view of expected poor graft survival in a blind eye, globe removal was offered. However, the patient refused the treatment and request for another corneal graft. This case highlights both the possibility of good outcome of cornea graft in such a case, and also illustrates that patient’s autonomy to refuse treatment option outweighs beneficence.

Transient cortical blindness is a rare but well-recognized complication of cerebral angiography. A 62-year-old woman with unruptured cerebral aneurysm and a 16-year-old boy with cerebellar hemangioblastoma experienced blindness after diagnostic cerebral angiography and tumor embolization, and the symptom resolved after 1 hour and 36 hours later, respectively. We report two cases of this complication.

The usual manifestations of Moyamoya disease are bilateral carotid narrowing or occlusion at the carotid fork and abundant basal.vascular network with various carotid neurovascular symptoms. We report two unusual cases showing visual symptoms(bilateral cortical blindness, right homonymous hemianopsia, respectively) and angiographically vertebrobasilar and complete proximal internal carotid occlusion, with extensive parenchymal and transdural anastomosis in Moyamoya disease.

'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.

Anton's syndrome is arguably the most striking form of anosognosia. Patients with this syndrome behave as if they can see despite their obvious blindness. Although best known for his description of asomatognosia and visual anosognosia, Gabriel Anton (1858-1933) made other significant contributions to the clinical neurosciences, including pioneering work in neurosurgery, neuropsychology, and child psychiatry. However, it has not been recognized in the English literature that Anton was also a dedicated advocate of eugenics and racial hygiene. This paper provides a case of Anton's syndrome and puts the works of Gabriel Anton into their historic context.

Transient cortical blindness is a known but rare complication occurring in 0.3~1% of patients undergoing cerebral or vertebral angiography. It is an extremely rare complication following cardiac catheterizaton and coronary arteriography. Cortical blindness is characterized by complete loss of visual perception and optokinetic nystagmus with preservation of ocular motility, pupillary responses, and normal fundoscopic examination. It has been suggested that its occurrence is due to an adverse reaction to the contrast agent, which causes an osmotic disruption of the blood-brain barrier. Patients outcome appears to be generally favorable with return of vision within 24-48 hr. We report a case of 48 year-old male patient with transient bilateral cortical blindness after coronary angiography.

Cortical Blindness is loss of vision due to injury of geniculocalcarine visual tract, usually caused by cerebrovascular disease. Cardiac arrest leads to global brain hypoxia or to more focal neurologic deficits. Cortical blindness is one form of these focal neurologic deficits. The severity of visual disturbance in cortical blindness is variable, so the diagnosis can be made later unless emergency physicians are familiar with it. We report a case of transient cortical blindness following hypoxic episode caused by coronary vasospasm.

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.
