Palinopsia, another effect of ciguatera

So I've had weird visual disturbances for a year and four months since I got ciguatera, and finally found out today what it's called: palinopsia. I see too many light shadows all the time making it hard to focus. Doctors call it overactive after-images. Very little is known about the condition, other than it rarely gets better and like ciguatera-caused nerve pain, is caused by over active neuron signals firing off. Great. Anyone else have this too?
