Optic atrophy And Driving

Hi there. Has anyone on here got Atrophy in their eye from recurrent optic neuritis?
if so please can you tell me what happened when the DVLA found out as i have a feeling im going to lose my licence?
I have permanent damage to my left optioc nerve having had 4 episodes of ON.
The DVLA have written to my consultant for further information so im a bit panicked
Thank you
