Pet turtles, especially hatchlings and young specimens, are very commonly afflicted with Vitamin A deficiencies and eye infections, both of which usually render the eyes swollen and/or difficult to open. Eventually, the turtle will become listless, cease feeding and decline rapidly in condition.
Addressing Eye Problems
While turtle eye drops are available and can be effective in certain situations, a veterinary visit should be your first step when your turtle exhibits any type of eye ailment. It is important to determine the nature of the problem before attempting treatment, as an infection will need be addressed differently than a Vitamin A deficiency. Only a veterinarian can make this determination. You can apply eye drops as a safeguard, but do not attempt treatment without a professional diagnosis.
Good Husbandry as a Disease Preventative
Be sure to provide your turtle with ample UVB radiation (the Zoo Med 10.0 bulb positioned within 12 inches of the basking site, is ideal), a balanced diet, and an appropriately warm basking site, so that its immune system will be functioning at full capacity.
As is true for all reptiles, proper husbandry is the most effective medicine at our disposal – please write in if you need specific information concerning the turtles in your collection.
