Corneal ulceration is a recognized complication that can arise from Bell's palsy due to the temporary or permanent inability to completely close the eye on the affected side. This condition stems from facial nerve paralysis, which can lead to inadequate eyelid closure, increasing the risk of exposure of the cornea to environmental factors and limiting adequate tear distribution. If the eye is not properly lubricated and protected, it can become dry, leading to irritation and, subsequently, ulceration of the cornea. This can be a serious condition requiring prompt treatment to prevent vision loss.

Other potential complications related to Bell's palsy can include issues with taste and facial distortion, but they do not pose the same level of immediate risk to vision as corneal ulceration does.
