98 Possible Causes for Central Scotoma on Visual Field Testing, Severely Reduced Central Responses on Multifocal ERG

  • Macular Dystrophy with Central Cone Involvement

    ERG responses to full-field testing are normal but multifocal studies reveal severely reduced central responses.[disorders.eyes.arizona.edu] […] acuity and loss of sensitivity in the central visual field, with nyctalopia occurring only in the late stages of the disease. 3,4 Visual field testing shows central scotomas[westcoastretina.com] As expected, visual field testing in cone dystrophy usually reveals a central scotoma.[en.wikipedia.org]

  • Goldmann-Favre Syndrome

  • Occult Macular Dystrophy

    The multifocal ERGs 4 demonstrated a loss of local responses in the central retina (fig 2C).[bjo.bmj.com] field tests obtained by Humphrey field analyzer central 24-2 threshold testing showed deep central scotoma in both eyes ( E , right eye; G , left eye). ( F , H ) Full-field[iovs.arvojournals.org] However, focal macular ERGs with 5, 10, and 15 degrees stimulus spots 3 were severely reduced and essentially absent (fig 2B).[bjo.bmj.com]

  • Leber's Hereditary Optic Neuropathy

    Swelling of the optic nerve head, vascular tortuosity, peripapillary telangiectasia, microangiopathy and central scotomas on visual field testing are all signs of LHON.[orpha.net]

  • Hereditary Optic Atrophy

    Swelling of the optic nerve head, vascular tortuosity, peripapillary telangiectasia, microangiopathy and central scotomas on visual field testing are all signs of LHON.[orpha.net] Other ophthalmologic manifestations of LHON include dyschromatopsia, diminished contrast sensitivity, and a bilateral dense central/centrocecal scotoma on visual field testing[webeye.ophth.uiowa.edu] Epidemiology Prevalence: 1/30,00 to 1/50,000 Affects males greater than females (4:1) Signs Visual acuities of 20/200 or worse Dense central/centrocecal scotoma on visual[webeye.ophth.uiowa.edu]

  • Low Tension Glaucoma

    Visual field test. This test measures your central and peripheral vision area.[mastereyeassociates.com] It helps tell if you have reduced visual sensitivity to certain areas within your visual field as well as lost visual field areas called scotomas.[mastereyeassociates.com] Although this test is useful and still the most used test in diagnosing glaucoma it is not as accurate in diagnosing early glaucoma as the GDxVCC.[mastereyeassociates.com]

  • Retinitis Pigmentosa

    A peripheral ring scotoma (detectable by visual field testing) widens gradually, and central vision may also be affected in advanced cases.[merckmanuals.com]

  • Paraneoplastic Syndrome

    The aforementioned posterior pole changes seen with disease progression in CAR have also been described in MAR. 10 Visual field testing most commonly reveals generalized constriction[reviewofophthalmology.com] Arcuate defects, and central and paracentral scotomas have also been reported. 10 The ERG in MAR is classically electronegative, demonstrating a preserved dark-adapted a-wave[reviewofophthalmology.com]

  • Retrobulbar Neuritis

    Swelling of the optic nerve head, vascular tortuosity, peripapillary telangiectasia, microangiopathy and central scotomas on visual field testing are all signs of LHON.[orpha.net] Visual field testing in our series demonstrated a dense central or cecocentral scotoma in 50%, whereas there was some impairment of color vision in all children.[doi.org] Similarly, on computerised perimetry eccentric fixation may influence the pattern of visual field defect.[doi.org]
