Hi doctor. From last 6 months I am experiencing slanted vision.. straight lines appear bent/curved. The rectangular television screen looks trapezoid. I am able to drive and do everyday tasks but distorted shapes still frustrate and annoy me. Been to 3 opthalmologists, dilated exam, retinal Oct and corneal topography ..all the tests have come out normal. I was quite stressed and anxious before the symptoms started ,I have general tendency to think a lot...hence I suspected mental stress as the cause. But now it has been 6 months, and stress is not always consistent. I am taking ssri for its management and each morning I wake up fresh,feeling that today I will see straight,yet I fail. I also came across a forum where 3 people reported exact same symptoms,their eye tests were normal too but then forum got closed in 2016 and I don't know how they got cured.My brain MRI (without contrast) is normal. I didn't go for with contrast due to fear of needles. please help.
