390 Possible Causes for Night Blindness, Scotoma

  • Retinitis

    Three months later, his corrected VA was 20/20 with relative scotoma in Amsler grid, normal color vision, no scotoma in HVF 10-2 and unchanged SDOCT findings.[] In young patients with the symptom of night blindness, it is important to differentiate retinitis pigmentosa from stationary night blindness.[] A peripheral ring scotoma (detectable by visual field testing) widens gradually, and central vision may also be affected in advanced cases.[]

  • Vitamin A Deficiency

    This suggested a relative scotoma likely related to rod photoreceptor deficiency (fig. 2 ).[] She presented at 33 weeks of pregnancy with night blindness as a result of vitamin A deficiency.[] Vitamin A deficiency and resulting night blindness have previously been reported in patients with chronic liver disease before undergoing liver transplantation.[]

  • Retinitis Pigmentosa

    Visual fields normalized except for a mid-peripheral absolute concentric scotoma. Five years after discontinuation of LLLT, a relapse was observed.[] The left eye of the same patient revealed typical PPRCA phenotype, with no night blindness, normal field, and normal ERG.[] Goldmann visual field tests detected mid-peripheral ring scotomas.[]

  • Night Blindness

    Goldmann perimetry showed no scotoma but slight depression with internal isoptors. No evidence for rod activity was observed by Goldmann-Weekers adaptometry.[] Also three case-reports are presented, which suggest that in some cases of congenital stationary night blindness (CSNB) the night blindness might arise from the absence of[] A central scotoma (an area of diminished vision) appears in the center of the visual field; and the eye is unable detect stationary objects as well as it can detect moving[]

  • Ocular Toxoplasmosis

    Confrontation visual fields revealed a central relative scotoma in the right eye and were full in the left eye. Extraocular movements were full in both eyes.[] The most common complaint of the patient is that of night blindness, followed by peripheral visual field loss. The patient had the typical features of RP.[]

  • Diabetic Retinopathy

    Diabetes-Related Eye Problems The symptoms of diabetic retinopathy (DR) and other eye problems related to diabetes are: Fluctuating vision Eye floaters and spots Development of a scotoma[] A 39-year-old woman with typical retinitis pigmentosa (RP) for 9 years and a positive family history of night blindness was diagnosed with diabetes mellitus (DM).[] Fluctuating vision Eye floaters and spots Development of a scotoma or shadow in your field of view Blurry and/or distorted vision Corneal abnormalities such as slow healing[]

  • Glaucoma

    A disc haemoorrhage may indicate a scotoma (glaucoma damage).[] If you suspect that you have acute glaucoma, call for medical assistance day or night.[] Typical evolution of field defects in primary open-angle glaucoma of the left eye (A and B, early field defects; C, more field defects with Roenne nasal step; D, Bjerrum scotoma[]

  • Retinopathy

    Solar retinopathy has symptoms of long term reduced visual acuity and paracentral scotoma.[] The short duration and rapid progression of symptoms along with the lack of family history of night blindness prompted a diagnosis of autoimmune retinopathy (AIR).[] Diabetes-Related Eye Problems The symptoms of diabetic retinopathy (DR) and other eye problems related to diabetes are: Fluctuating vision Eye floaters and spots Development of a scotoma[]

  • Usher Syndrome

    Best-corrected visual acuity ranged from 20/16 to 20/40, with scotomas beginning at 3 eccentricity.[] blindness and profound deafness since birth.[] When cones begin to die, blind spots (called scotomas) can develop, even in well-lighted conditions.[]

  • Cancer-Associated Retinopathy

    He had visual disturbance, ring-like scotoma, and night blindness bilaterally. There were narrowed retinal arterioles and dilated retinal venules.[] Goldmann perimetry revealed a ring-like scotoma in each eye, and the electroretinogram was nonrecordable.[] After two weeks, she complained of a sense of darkness and night blindness.[]
