Hermann Tortoise Eye Problems

by Tom
(England)

Hi, I have had my hermanns tortoise for the past 4 years and have never experienced any health problems however i have noticed that he is reluctant to open his eyes and when i can ease them open during batheing they seem white and dull with a small white protuding dot in the centre, i have looked all over and cannot find a diagnosis or treatment for this.
The picture shown is him with his eye open when dry.
