I've been following this thread because my little Russian also has swollen eyes and is off of his food.
Just an FYI about carrot baby food. If the baby food soaks are intended to provide vitamin A, you'd better check the nutritional labels before buying. I went to buy carrot baby food today and found that every brand had ZERO Vitamin A.
If you want high vitamin A baby food, check the nutrition labels first. I ended up buying an organic blend of sweet potato, blueberry and apple. It has 150% of the RDA for Vitamin A per serving. There was another high vitamin A blend but it contained yogurt so I avoided it. Another option would be to buy fresh carrots and puree them.
I think that your russian might have a bulb issue. What light are you using for UV?
Luckily I do not think this is related to the incredibly contagious bacterial infection seen on sulcatas recently
