I got my almost 2 year old corn almost a year ago and a friend told me, she thinks he may be blind. I wanted to run the behaviour that led me and her to wonder this past you guys to see what you think.
When i first got him in autumn 2011 he never strike fed and would get to his mouse later on. In spring/summer though he went through a major growth spurt, put on weight (he was a skinny little boy) and it was then i noticed something was off. He'd coil his neck to strike, but would always only just grab it, and it would always be in places i wouldn't expect. He'd bite to the side and only get half of the head, or would bite completely side on to the head. Occasionally he'd whack his head straight into the floor next to it. He'd eat it as normal once he had hold of it. I also watched him eat when i just left it for him to find a few times and he'd bite at the stomach, or have to adjust himself a lot to get to the right position. I placed him a few cm in front of a mirror on my wardrobe doors and he'd often go straight into it, almost as if he didn't know it was there. When he was in front of it, literally touching he'd respond angrily, like there was another snake there - coiling his neck, hissing and even rattling his tail! If he was a few cm away there'd be nothing until he was near touching it. if you place him on a table or a shelf, when the ground stops he'll nosy around with his head till he hits something solid and will follow it. When i put him in his new viv with shelves he spent quite a while trying to figure out how to reach his favourite hide - its like he could smell it but couldn't get a path to it just by following the wall. In the end he discovered the stick i placed as a ladder and was absolutely fine with getting too it. He will respond to a camera flash but his eyes often can't focus on one thing. I know they don't have fantastic sight anyway and i figure their excellent sense of smell takes over a lot of the time. My friend is in her final year of studying to be a vet, checked him over for me and watched him feed. She said that he seems like he blind but i'd need a reptile expert to look to be sure.
Does it seem like he's blind from what i describe though? A blind snake doesn't fuss me too much - it's easy to accommodate. The shop told me he was bred by monkfield nutrition, which im told is an intensive farm so this wouldn't surprise me if he is.
Thanks! Heres a photo to make sure:

Hi there , I'm no expert but everything you have described seems pretty normal to me..

When i first got him in autumn 2011 he never strike fed and would get to his mouse later on. My girl never strikes usually i dangle infron and she kind of hap-hazardously bumps into it.. In spring/summer though he went through a major growth spurt, put on weight (he was a skinny little boy) and it was then i noticed something was off. He'd coil his neck to strike, but would always only just grab it, and it would always be in places i wouldn't expect. He'd bite to the side and only get half of the head, or would bite completely side on to the head.My male strikes quite vigorously and 9 times out of 10 wont get an end and will grab it by the middle, coil it then spend 5 minutes sniffing it trying to figure out how to eat it sideways..?? lol Occasionally he'd whack his head straight into the floor next to it.My Boa does this He'd eat it as normal once he had hold of it. I also watched him eat when i just left it for him to find a few times and he'd bite at the stomach, or have to adjust himself a lot to get to the right position.Ive watched the boa sniff a fluff for 10 minutes and not work out how to eat it lol! I placed him a few cm in front of a mirror on my wardrobe doors and he'd often go straight into it, My dog does this lol mirrors are just confusing to animals as they are to young children, i ran into several mirrors when i was younger lol almost as if he didn't know it was there. When he was in front of it, literally touching he'd respond angrily, like there was another snake there - coiling his neck, hissing and even rattling his tail! If he was a few cm away there'd be nothing until he was near touching it. Spent many an hour watching my cat attack a mirror thinking it was another cat and my dog licks mirrors when he sees his reflection lol if you place him on a table or a shelf, when the ground stops he'll nosy around with his head till he hits something solid and will follow it. When i put him in his new viv with shelves he spent quite a while trying to figure out how to reach his favourite hide - its like he could smell it but couldn't get a path to it just by following the wall. Both my two will 90% of the time explore there vivs sticking to the walls it's safer there they feel, if you loose a snake the always say look around the edges of the room if they are out in the open they feel like easy preyIn the end he discovered the stick i placed as a ladder and was absolutely fine with getting too it.

There are certain things you can check that are related to eyesight - for one, do his pupils increase and decrease in size if you change the lighting levels? If you make a movement near his eye as if you're going to tap his eye (don't actually tap it of course, and try to make sure you move as little air as possible), does he respond in any way? (this second one isn't foolproof as snakes tend not to respond to many things :)). If you hold his body and let his head free to explore and you put him, say, near the edge of a table, will he find it?
From what you described, that sounds like a lot of the things my snakes do as well :) I wouldn't worry too much. The above questions could help you find more hints towards any possible problem though :) |

do his pupils increase and decrease in size if you change the lighting levels? checked this just now by having him in a darkish room and then putting a torch light onto them - the pupils didnt change, even after a few goes.
If you make a movement near his eye as if you're going to tap his eye (don't actually tap it of course, and try to make sure you move as little air as possible), does he respond in any way I forgot to mention this - he doesn't at all. i've stood in front of a fan with him closest to the fan so that the air blows past him towards me so there is less wind and smell and i've accidentally tapped his eye and that was the only reaction i got. he doesn't respond if i stand like that and wave my finger in front of his eyes
If you hold his body and let his head free to explore and you put him, say, near the edge of a table, will he find it? not sure i know what you meant, but i put him on tables and if he's going too fast the edge takes him by surprise and he struggles to stop. he's fallen off before. if i hold him he wont do what the babies do and immediately aim for the edge of the table to act as a lever to pull away - he'll move his head round in all directions till he hits it and then it'll take him a bit of exploring to find the edge to lever himself away.
with regards to feeding he's very... delicate in how he feeds. he doesn't get carried away and if i make any noise at all he'll stop instantly. The other snakes i've fed are very into their food and determined to take it down in whatever angle they have. seb only seems to want the head and he'll spend time finding it. if he bites the stomach he'll let go and move round towards the head - often goes the wrong way though and gets the rear. he'll keep moving till he gets a solid skull though :)
i'll keep an eye on him and hopefully he isn't - it doesnt matter either way though he's still gorgeous :D glad i double checked this too! |

You could pop him to a vet and get them to give him the once over. Midnight was the San with food, not bother wouldnt eat it until she was alone and silent. I think the food thing is separate, more character than sight x. If you cover his eyes and stand under light his pupils should change, the level of light change has to be quite dramatic to get a good idea x |

They don't have great eyesight or aim as it is, mine are terrible lol! If you're concerned, get him checked out by a reptile vet, but most of what you've told us sounds normal, apart from maybe his pupils not changing at all in extreme lights. |
