Lattice degeneration with flashes

[myope15]

I am severely myopic -16 in right eye and -20 in left eye. I was diagnosed with lattice in my left eye 2 years ago. I  have been seeing some flashes in the periphery of left eye. Over the last two years, I have been to a number of Retina specialists some of whom have suggested laser treatment while some haven't.
Even extensive search on the internet about lattice doesn't lead to anything conclusive either.I am a little confused as what to do. Does lattice accompanied with flashes merit treatment??

Thank for your prompt reply.
I don't know whether there is a horseshoe tear or not. None of my medical reports have the word "horseshoe", its pretty much superior lattice, myopic disc and snail track.
Are horseshoe tracks difficult to see in an indirect retinal examination?

You will get many opinion.  I believe you do not need laser treatment for lattice even with flashes UNLESS you develop a horseshoe tear.  Laser can to lattice can not prevent a retinal detachment since a tear can occur in normal appearing retina.  The complications of laser is about 5%--epiretinal membrane formation and possible retinal tear leading to detachment.  8% to 10% of the population has lattice degeneration.  An acute horseshoe tears has about a 35% chance of leading to a retinal detachment without treatment.
