Dynamic color is an important carrier that takes information in some special ***,up to the present,there are no available and objective tests to evaluate dynamic color *** investigate the characteristics of dynamic color processing,we adopted two patterns of visual stimulus called "onset-offset" which reflected static color stimuli and "sustained moving" without abrupt mode which reflected dynamic color stimuli to evoke event-related brain potentials (ERPs) in primary color amblyopia patients (abnormal group) and subjects with normal color recognition ability (normal group).ERPs were recorded by Neuroscan *** results showed that in the normal group,ERPs in response to the dynamic red stimulus showed frontal positive amplitudes with a latency of about 180 ms,a negative peak at about 240 ms and a peak latency of the late positive potential (LPP) in a time window between 290 and 580 *** the abnormal group,ERPs in response to the dynamic red stimulus were fully lost and characterized by vanished amplitudes between 0 and 800 *** significant difference was noted in ERPs in response to the dynamic green and blue stimulus between the two groups (P>0.05).ERPs of the two groups in response to the static red,green and blue stimulus were not much different,showing a transient negative peak at about 170 ms and a peak latency of LPP in a time window between 350 and 650 *** results first revealed that some subjects who were not identified as color blindness under static color recognition could not completely apperceive a sort of dynamic red stimulus by ERPs,which was called "dynamic red blindness".Furthermore,these results also indicated that low-frequency ERPs induced by "sustained moving" may be a good and new method to test dynamic color perception competence.

Background: Zygomatic fracture is one of the most prevalent one among facial fractures caused by vehicle accident, motorcycle accident, fighting, fall and sport injuries. Materials & Methods: This study was a retrospective study of our patients during past 6 years. Results: We had 1277 facial fractures, of whom 9 patients had blindness. We had 193 patients with Zygomatic fracture. 98 patients had pure zygomatic fracture and other had complicated fractures. Frequency of blindness due to zygomatic fracture in a period of six years was 4.7% in all and in pure zygomatic fractures was 2.04%. blindness was most prevalent in age group 20 - 29 years old (55.6%). The most prevalent cause of zygomatic fracture which causes blindness, was motor vehicle accident (77.8%). blindness was more common in males (77.8%) than females (22.2%). Discussion and Conclusions: One of the most disastrous complication of zygomatic fracture is transection of optic nerve. Very careful examination of fractured bones careful examination of optic nerve and visual acuity and urgent operation and decompression of optic nerve must be performed. About 4% - 5% will have blindness purely due to fracture.

Introduction: Conjunctival-corneal or choroidal calcifications are frequent in SHPT, blindness is however exceptional. We report a case of blindness secondary to compressive ischemic optic neuropathy. Case Report: Mr. B.E.K., 49 years old, has a chronic renal failure secondary to unlabeled glomerular nephropathy for 17 years. He has been on chronic hemodialysis for 12 years and has had SHPT for nine years. He secondarily developed disabling segmental osteoarticular deformities associated with kyphoscoliosis, “drumstick” fingers and facial dysmorphism. Five months before admission he developed eye pain and reduced visual acuity progressing within one month to blindness. Biology noted: serum creatinine at 726 umol/l (60 - 120 umol/L), azotemia at 14.3 mmol/l (2.5 - 7.5 mmol/L), serum calcium at 2.25 (2.25 - 2.55 mmol/L), phosphatemia at 1.13 (0.8 - 1.35 mmol/L), alkaline phosphatases at 2196 (5 - 270 IU/L) and parathyroid hormone level at 2257 (10 - 60 pg/mL). Retinal angiography revealed lesions suggestive of ischemic neuropathy. The orbit CT scan with 3D coronal reconstruction revealed narrowing of the caliber of the optical channels with dystrophic thickening of the skull base and cranial vault. Cranioencephalic and orbital MRI revealed diffuse brown tumors and pre-chiasmatic optic atrophy. Discussion: The most frequent ocular complications of SHPT are conjunctival-corneal or sclero-choroidal calcifications, asymptomatic, associated with hypercalcemia. Compressive manifestations are rarer, represented mainly by an amputation of the visual field, diplopia, ptosis or blindness, as described in our patient. The main cause is osteodystrophy and brown tumors of the skull base (1% - 2%). Conclusion: This case report underlines the importance of early detection of SHPT, in order to avoid its major complications, such as blindness, especially since current preventive and curative measures have proven their

blindness is a serious complication that can occur after facial trauma and may represent the loss of one of the most useful senses in the human relationship with the world—the sight. This study aims to review the pathophysiology of blindness related to facial trauma in order to identify the mechanisms by which it develops and to recognize the signs and symptoms required to establish proper diagnosis and treatment. blindness following facial trauma may occur due to mechanisms that involve injury to the eyeball, optic nerve and eyelids. The leading causes of blindness resulting from facial trauma, and which may be altered by medical interference, are related to retrobulbar hemorrhage and traumatic optic neuropathy, which require extremely rapid diagnosis and can be accomplished with the resources available in most trauma-based emergency services. The authors conclude that loss of vision tends to be irreversible in direct eyeball and optic nerve lesions, but can be prevented in retrobulbar hemorrhage and traumatic optic neuropathy. Eyeball and, especially, sight accuracy evaluation should be included in the initial care of trauma patients, so that the lesions that might lead to loss of vision are diagnosed and treated early.

Aim: A population-based survey was conducted in Tuoketuo and Shangdu Counties in Inner Mongolia Autonomous Region, China, in the Autumn of 2010, to assess the prevalence and causes of blindness and visual impairment of people aged 50 years and over. Methods: Random cluster sampling was used to select 82 clusters of 50 residents in the 2 counties. Each survey team included an ophthalmologist, a nurse and a coordinator, who went to door to door in each cluster to identify eligible people. A torch, direct ophthalmoscope and portable slit lamp were used for eye examination. Visual acuity (VA) was tested for each eye of every subject. Those with VA below 6/18 in either eye were examined and causes identified. Results: The survey identified a prevalence of blindness in people aged 50+ in Tuoketuo of 1.2% (95% Confidence Interval: 0.7% - 1.7%) and in Shangdu of 1.4% (95% CI: 1.0% - 1.9%). Cataract was identified as the leading cause of blindness (BL) and severe visual impairment (SVI), and uncorrected refractive errors were the major causes of moderate visual impairment (MVI) in both counties. Over two thirds of blindness, SVI and MVI were identified as avoidable. Conclusions: The prevalence of blindness in people aged 50+ in Tuoketuo and Shangdu was low compared to other studies conducted in China [1] [2]. The prevalence of blindness of people aged 50 years and over could be reduced by up to two thirds through better eye services in the two study areas.

Visuality can be generically described as the quality of the visual,that is,as the given visual field in which a subject’s attention is *** fact,the visual is intrinsically linked to human vision,and this presupposes the existence of a visible horizon from which(visual)images are ***,this formulation presents something uncanny paradoxical because it forgets,on one hand,the broader status of the image(such as auditory and olfactory images)-seeing is not just a visual process(at least since Diderot we know it)and there are mental mechanisms in the visual constitution process that help to fabricate reality and that gestalt theory has explained-and on the other hand,the possibility of seeing beyond what is visible,after all,everything(or almost everything)that presents itself in a digital and virtual environment it can be quite ontologically *** on some of these premises,we will trace a path of analysis that leads us to the current blindness:unconditional faith in digital technology and the fragile hope of happiness in a way that rejects the reality of the visible.
