Winter lami in a Cushings horse or pony is not "caused" by lush grazing, frosted grass etc, although that won't help getting the lami under control.
I learnt this when my TBx was diagnosed in 2009 with Cushings. I was shocked because he has none of the typical Cushings signs, for instance very hairy, drinking loads, and as a result peeing loads, and quite often the hollows above their eyes are filled in - my horse had none of these signs but his blood test said he definitely is.
I joined this online group http://pets.groups.yahoo.com/group/EquineCushings/ for help and support for owners of Cushings equines. This is where I learnt that it is the increase in the ACTH in their blood which indicates they are at great risk of laminitis.
They discovered that all horses experience an increase in the ACTH starting late summer and rising until late December. (cant remember what it stands for but find out on the web site) but if a horse has Cushings, it rises much higher and if it is not brought down to "normal" levels, bang, they get hit with laminitis. It is the ACTH which is measured in a blood test to diagnose Cushings.
Please go on this web site for information http://www.ecirhorse.com/
and then join the Cushing group. They have well over 10,000 members now all contributing their experiences and advice on how to manage their diets etc. There are expert moderators on there who will come to your aid if you cannot get the lami under control. No amount of soaking hay/haylage or starving or keeping off grass will help if the ACTH is still very high, the lami will continue until it is brought down.
Have I stressed it enough? It is not the grass that causes the lami in a Cushings horse and if your horse has lami at this time of year it WILL almost certainly have cushings, even if it is under 10 years of age, it is still possible!

There was a lot of posters a on previous thread about winter laminitis so I wanted to draw their attention to this new discovery about why their ponies are not getting better, or are coming down with lami in winter.

TelH - Hi -when was this? What test did the vet do, was it the ACTH blood test?

Yes that was the test he had. He started with laminitis in the week between Christmas 2005 and New year 2006, he was rising 10. The vet said the chances of him having cushings at that age were slim but he did the test because there was no other explanation for him getting laminitis. The test came back that he didn't have cushings. But he was off for a long time and came close to being pts.
He eventually started back in work in Sept 2007 and touch wood has not had a days lameness since. The vet and farrier were both at a loss as to why he got it, why it got so bad and why he suddenly started to improve. I remember the vet saying when you see ponies like this you realise how little we actually know and how much more research needs doing into laminitis.

My results came back today - yes she has Cushings with a reading of 84 for ACTH. Absolutely no symptoms whatsoever apart from sudden and very acute laminitis which started at the weekend. Her shape is normal for a 28 year old, she has good topline apart from along her actual spine, she is lucky if she drinks 2 gallons at night, pees just the same as she ever did and has a lovely soft fluffy coat which is no different from any other year. Lots of people have commented how well she looks and while she likes to spend alot of her day dozing, she has done for years not least because she chomps lots of barbiturates every day. The laminitis is gradually resolving - at least she spends her day on her feet now and she can potter around her stable more comfortably but she starts the Pracend tomorrow morning. I am hoping to use alternative therapies to help control things, but right now the priority is to get rid of the laminitis.

Completely agree with this.

My lami prone horse has been so much easier to manage since being diagnosed with Cushings and having Prascend. I had to push the vet for the test - because the horse had very limited signs (only puffy eyes) the less experienced vets were unwilling to test.

So if your horse has more than one spell of laminitus/foot abcesses I would really recommend ruling cushings out. He is now living out 24/7. Admittedly limited grass and poor hay, but we are both now very happy!!
