  • 1.  visual disturbance in superior field od and os

    Anyone seen this? 
    Superior visual snow? 

    I have a 21yo male farmer with 2 years of constant superior visual disturbance initially intermittent now constant. Describes it as a waviness in both eyes. The waviness moves and drifts. 
    Came on after waking. 
    No headaches at the time. Not a headache sufferer. 
    Has had a hx of migraine but not significant. 


    Formal visual fields and OCT RNFL , macula and GCL are normal.
    MRI brain and orbits normal
    EEG normal
    Had VEP, mfERG and all normal

    Tried pizotifen, endep, sumitriptan, topirimate, magnesium, riboflavin, 
    Then tried ajovy one injection and had numbness on left side and mgiraines but made no difference to superior field disturbance. 
     This is a schematic of what he sees in his vision binocularly.

    Has the patient been dilated and examined by an ophthalmologist.  Sounds like bilateral, progressive, inferior vitreous detachments.

    Hi,
    I understand it's bilateral, but has anyone done optos imaging with autofluorescence? Seems retinal or vitreous related. Agree.

    Sudden bilateral inferior PVD on getting up in the morning in a 21 year old causing superior field waviness,  is kind of odd.
    The drawing is of the binocular field of vision or unilateral ?
