Balint syndrome is the triad of simultanagnosia, optic ataxia (misreaching for visual targets), and ocular apraxia (inability to control voluntary eye movements, although the eyes can move spontaneously in all directions). (msdmanuals.com)
Select one of the disorders covered in the book (simultanagnosia, prosopagnosia, ocular apraxia, optic ataxia, or Balint's syndrome) and research its clinical etiology, symptoms, and treatments. (bestnursingtutor.com)
Posterior1
Ocular findings include anterior lenticonus (which is virtually pathognomonic), maculopathy (whitish or yellowish flecks or granulations in the perimacular region), corneal endothelial vesicles (posterior polymorphous dystrophy), and recurrent corneal erosion. (nih.gov)
Atrophy1
Optic atrophy, nystagmus, and strabismus have been reported in addition to dysmorphic periocular features such as epicanthal folds, upslanting lid fissures, and a flattened nasal bridge. (arizona.edu)
Syndrome1
This type of visual attention problem is one of three major components (the others being optic ataxia and optic apraxia) of Bálint's syndrome, an uncommon and incompletely understood variety of severe neuropsychological impairments involving space representation (visuospatial processing). (wikipedia.org)
Nerve1
More recently, a subset of OCT, the OCT Angiography is a modality that images integrity of the vasculature in the retina and optic nerve mainly assessing the blood perfusion. (aao.org)
Findings2
Due to the genetic heterogeneity, the fundal features are highly variable as well but patients usually have symmetrical ocular findings. (gene.vision)
Other findings can include broad or webbed neck, unusual chest shape with superior pectus carinatum and inferior pectus excavatum, cryptorchidism, varied coagulation defects, lymphatic dysplasias, and ocular abnormalities. (beds.ac.uk)
Photophobia1
The non-nephropathic (ocular) form of cystinosis is characterized clinically only by photophobia resulting from corneal cystine crystal accumulation. (nih.gov)
Cerebellar ataxia1
Spinocerebellar ataxia type 2 (SCA2) is characterized by progressive cerebellar ataxia, including nystagmus, slow saccadic eye movements, and in some individuals, ophthalmoparesis or parkinsonism. (nih.gov)
Oculomotor apraxia2
We thus report the first cases of oculomotor apraxia in DCMA syndrome. (nih.gov)
The ataxia telangiectasia Rad3-related (ATR) protein responds to UV damage, whereas the ataxia telangiectasia mutated (ATM) protein responds to double-strand breaks (DSBs) caused by ionizing radiation and radiomimetic compounds. (medscape.com)
Nerve1
Blurred vision (and episodes of "graying out"): These may suggest serious optic nerve compromise, which should be treated as an emergency. (medscape.com)
Dystonia1
There are often involuntary and hyperkinetic movements with dystonia, dyskinesia, ataxia and choreoathetosis. (arizona.edu)
Autosomal1
ARSACS is now recognised as one of the important causes of autosomal recessive ataxia. (acnr.co.uk)
Neurologic1
Individuals with intermediate/milder ZSD do not have congenital malformations, but rather progressive peroxisome dysfunction variably manifest as sensory loss (secondary to retinal dystrophy and sensorineural hearing loss), neurologic involvement (ataxia, polyneuropathy, and leukodystrophy), liver dysfunction, adrenal insufficiency, and renal oxalate stones. (nih.gov)
Patients2
Older patients have limb and truncal ataxia and experience frequent falls. (arizona.edu)
This has been accredited as the first centre of clinical excellence in the UK by Ataxia UK and more recently by the National Ataxia Foundation, charities of ataxia patients in the UK and USA respectively. (acnr.co.uk)
Deficiency1
137 Section on Experimental Pathology Carter-Dawson, Louvenia, Ph.D. Effects of Vitamin A Deficiency on Ocular Tissues 141 Kuwabara, Toichiro, M.D. Anatomical and Pathological Studies of Ocular Tissues 145 Light Effect on the Retina 153 Robison, W. Gerald, Jr., PhiD. (nih.gov)
Globes1
Ocular globes are deviated downward, the upper lids are retracted, and the white sclerae may be visible above the iris. (medscape.com)
Disorders2
She completed her training in neurology in the same university and obtained her PhD researching neurogenetic disorders and the dominant ataxias. (acnr.co.uk)
As a result, a number of rare neurogenetic disorders show increased prevalence or local variants in this region, including Friedreich's ataxia (FRDA), and other hereditary ataxias, spastic parapareses and neuropathies. (acnr.co.uk)
Speech1
In this setting she has established the first Ataxia Multidisciplinary clinic that sees a Neurologist specialised in ataxia together with a speech and language, occupational and physiotherapists. (acnr.co.uk)
Disorder1
Dislocated lenses are the only significant ocular features of this disorder. (arizona.edu)
Clinical1
She established the first Ataxia Centre at the NHNN in 2005, a robust model of translational clinical service. (acnr.co.uk)
Poor1
Symptoms of irritability, poor feeding, ataxia, and language development may be seen in the first year or two of life. (arizona.edu)
