What is causing my right eye pupil dilation? I have been suffering from grand mal seizures, with severe headaches, right side only temple swelling, right eye pupil dilation, and also a sore right beside the afflicted eye.

In brief: You

You should immediately make an appointment with an ophthalmologist and a neurologist.
You don't say how long this has been going on, or whether your vision is affected, but there could be very serious problems. If this just started and you cannot get an appointment immediately, go to the emergency room.

In brief: See a physician

Seizures, headache, and a dilated pupil can be something very serious such as a brain aneurysm or tumor. Medical attention should be sought right away.
Cat scans or MRI scans can help to make the diagnosis.

In brief: Also,

Also, other causes of abnormally large pupils can be accidental use of dilating agents (scopolamine patch, dilating drops, etc) or adies tonic pupil, or even trauma.
These are rare causes.

In brief: Need to get images

A focally enlarged pupil can be a sign of a posterior communicating artery aneurysm, and needs to be addressed asap.
Hopefully this is a benign adie's pupil, but do not assume all is well, get reassured immediately.
