short lived curvedline of small geometric images(triangles?) appears on left side of my peripheral

 3 times in the past 8-9 months I have had a floating distortion in my field of vision - difficult to discern in detail but something like a (slightly curved?) L shape made up of a train of smaller L shapes (or triangles), situated to the left side of my field of vision and lasting for less than an hour in each case. I have had several bouts of laser surgery to repair a slight retinal tear in the past 20 years but have been in the clear for my past 2 bi-annual checkups.The line is sometimes partially coloured and has a geometric quality to it like a diffraction of light.

Is this something anyone else has experienced?

    Is this when your eyes are open or when they are closed? I had laser surgery to treat a retinal hole and experience this, generally in the dark or with my eyes closed but I do have it on occasion with my eyes open in the light. I also see geometric patterns across my entire line of sign in the dark especially with my eyes closed. This began after my laser retinal repair.

      Eyes open! and unaffected if I close one of my eyes. Also unaffected if I use my spare pair of glasses so the problem is definitely with the eyes/optical system. This is LONG (maybe 10+ years) after any laser surgery I have had.

    Have resolved this matter with help from another source suggesting Ophthalmic Migraine was very close to the mark according to examples shown at Ophthalmic Migraine Pictures to Pin on Pinterest - PinsDaddy

    but What is an Ocular Migraine(https://migrainemantras.files.wordpress.com/2017/07/2.png?w=620[/b] wink gave me pause for thought ( aka visual. retinal, ophthalmic or monocular(meaning one eye) migraines...cause vision loss or blindness in one eye(differs from an aura which affects both eyes)) & Migraine Aura (https://www.mayoclinic.org/diseases-conditions/...with.../migraine-aura/vid-20084707)  appears to fit the bill better

    "The best known visual aura is called a fortification spectrum because its pattern resembles the walls of a medieval fort. It may start as a small hole of light or sometimes as bright geometrical lines and shapes in your visual field. This visual aura may expand into a sickle- or C-shaped object, with zigzag lines on the leading edge. As it moves, it may appear to grow. Auras aren't the same for everyone, so you might also experience bright spots or flashes. Auras are sometimes accompanied by a partial loss of vision referred to as a scotoma. Auras commonly last 10 to 30 minutes"

     

    P.S. Scintillating Scotoma/Visual Migraine(https://en.wikipedia.org/wiki/Scintillating_scotoma) is a related condition

     

    Another useful contact found along the way is the Ocular Migraine Network  www.ocularmigraine.net
