In my experience, OASC are fairly inflexible regards medical problems. They have a fairly black and white approach to things it seems. With respect to your flying ability, OASC are reluctant to acknowledge good flying scores as an acceptable substitute for aptitude test failings so I find it hard to believe that they would look past a medical problem on these grounds.
Good luck with it all, but I've seen people with very high FHT passes get binned with eyesight problems so you might have an uphill struggle.
Hope that helps, sorry if it wasn't what you wanted to hear
