WS sufferers sometimes notice drying of their eyes, with their tears becoming more “gummy,” which can result in blurred vision. The blurred vision may be associated with drying of the outer layers of the cornea. In some cases, the blurred vision seems to come and go with the patient’s level of fluid retention. This suggests that the blurred vision may be caused by a degree of fluid retention within the eyeball causing temporary changes in the shape of the eye. The blurred vision associated with Wilson’s Temperature Syndrome sometimes comes and goes, and is not always persistent. A patient’s vision strength can also change and may come and go as well.

One patient that I can remember in particular, developed Wilson’s Temperature Syndrome quite a few years previously after a severe stress. Over the ensuing years, not only did the other symptoms of Wilson’s Temperature Syndrome worsen but she noticed that the prescriptions for her glasses needed to be made stronger and stronger because her eyes were weakening more quickly than they had in previous years. With normalization of body temperature patterns, not only did the other symptoms of Wilson’s Temperature Syndrome improve, but she found that she was able to return to the previous prescriptions for her eyesight.

Quite frequently, patients find that they can’t read the fine print on some days while they can on others. They may need glasses or someone else to read the fine print, whereas on other days they might be able to read the print easily. Interestingly, these vision changes do not seem to be improved even after rubbing of the eyes to clear it. So it is probably not related to the tears.
