What a helpful thread, thank you cheeky ginger :)
gaschick we are also in the relatively early stages of diagnosis of superior oblique palsy, in my 3 year old DS left eye. He has been seeing the consultant since last August following a fast-track referral due to the 'squint' and head tilt (and an incredibly fraught and worrying weekend sitting on hands so as to not scare ourselves silly with googling). Thankfully there was nothing sinister, 'just' the superior oblique palsy.
Our consultant said there shouldn't be any impact on DS sight due to the sup ob palsy on its own, there is a slight risk that it could deteriorate if it becomes too hard work for DS (or he becomes lazy I guess) to correct his vision with the tilt and messages on the pathways from eye-brain become less efficient (reeaally poor description there, sorry!) but glasses wouldn't have any positive impact for the sup ob palsy in its own right. That seems at odds at what you have been told about binocular vision gaschick, so would be interested to hear cheekyginger's take on that.
DS had another eye test and consultant appt on Monday, and he now has to go back for the drops again in April as he has developed a slight (I think consultant said 0.5, but not certain now, need a dictaphone!) astigmatism since August and will likely need a prescription for that, but that's in his right eye and as far as is possible to say, is completely separate issue to the sup ob palsy. Would be interested in your thoughts on the likelihood of a prescription for that cheekyginger, whether that is likely to be long term and if so whether he will need to wear glasses full time - I have an astigmatism (no idea what my numbers are though) and only wear mine for driving/reading/working.
Consultant was also sounding more operation focused this time to correct the sup ob palsy, whereas last time he was very hands off, would only really for cosmetic reasons so long as DS is correcting by tilting, again now I'm not so sure.
Have also done some serious mummy-bashing about whether this is something we could have prevented, he had some fairly hurty head bangs last summer, one thing after another and still always that small niggle in the back of my mind that it is something more sinister despite the consultant being unable to find any signs of pressure on the optic nerve. Once the seed has been planted though....:(
