Why does Gattuso need an eye patch?

Napoli coach Gennaro Gattuso sported an eye-patch during tonight’s game with Lazio, as he has long suffered from Ocular Myasthenia.

This is an auto-immune disease that affects the extraocular muscles, which control the eyes and eyelids.

They become easily weakened and can cause double vision or drooping eyelids.

In order to combat this double vision, Gattuso has been wearing corrective glasses, then a patch on his right eye.

The condition can flare up occasionally and seem to have been troubling Gattuso for the last 7-10 days.
