44 Possible Causes for Enlarged Blind Spot, MRI Scan of the Brain Abnormal

  • Idiopathic Intracranial Hypertension

    In patients with visual loss, the most common perimetric finding was partial arcuate visual field defect with an enlarged blind spot, and patients tended to have mild loss[] Imaging tests Your doctor may perform a CT or MRI scan of your brain to look for signs of spinal fluid pressure.[] . – Enlarged blind spot or other visual field loss. – Diplopia. 6. Associated Conditions  Before examination, think!?[]

  • Astrocytoma of the Brain

    Changes (such as swelling) may be observed in the back of the eye, where the blind spot is.[] In young children, the growing pressure of an astrocytoma tumor inside the skull may enlarge the head.[]

  • Brain Neoplasm

    These let doctors see inside the brain and identify any areas that look abnormal. Although both are painless, they do require children to be still.[] brain abnormalities magnetic resonance imaging (MRI) to detect tumors beneath the bones of the skull electroencephalography (EEG) to measure the electrical activity in the[] Diagnosis A doctor who thinks a child might have a brain tumor will do a thorough neurological exam and order imaging studies of the brain: a CT (computed tomography) scan[]

  • Brain Abscess

    MRI has higher resolution and can show early abnormalities better than CT.[] However, additional tests may be needed to establish the diagnosis because a brain tumor or damage due to a stroke or multiple sclerosis can resemble a brain abscess.[] If MRI is unavailable, computed tomography (CT) can be done after a radiopaque contrast agent (which makes abscesses easier to see on CT scans) is injected intravenously.[]

  • Malignant Glioma

    Quality as well as quantity of life is important and must be formally assessed The management of malignant glioma presents challenges for neurosurgeons and oncologists alike. Surgery with postoperative radiotherapy remains the “gold standard” treatment for this group of patients. Neurosurgical procedures are[…][]

  • Papilledema

    It can progress to enlargement of the blind spot, blurring of vision, visual obscurations (inability to see in a particular part of the visual field for a period of time).[] If there is no abnormality on the brain scan, most patients will need to have a lumbar puncture (spinal tap) done so that the pressure of the cerebral spinal fluid can be[] Goldmann visual field revealed an enlarged blind spot in the right eye only ( Figure 2 ).[]

  • Subdural Hematoma

    Patients whose CT scans reveal no abnormalities but who have clinical abnormalities on examination or significant symptomatic complaints may have abnormalities on brain MRI[] scans.[]

  • Cavernous Sinus Thrombosis

    The condition may be diagnosed through a complete physical exam, CT scan or MRI scan of the brain Intravenous antibiotics are the mainstay of treatment.[] […] infection The common signs and symptoms of Cavernous Sinus Thrombosis include severe headaches, pain in the eyes, red eyes, involuntary movements of the eyes, and vision abnormalities[]

  • Ophthalmic Migraine

    The blind spot usually enlarges and may move across your field of vision.[] Such testing may include: Magnetic Resonance Imaging (MRI) which can show abnormal cell growth in the soft tissue of the brain CT Scan can show abnormal cell growth in the[] The blind spot usually enlarges and may move across their field of vision.[]

  • Fabry Disease

G.[] MRI and CT Scanning Brain MRI or computed tomography (CT) scans should be obtained to visualize the site and extent of infarction.[] More recently, an enlargement of the blind spot (Figure 23 ) was reported in 38.7% (n 27) of patients, although this was not associated with any defects in colour vision [[]
