Can you give me some additional information?
1. Your age and gender?
2. Do you suffer from any medical conditions
3. Are you taking any medications?
4. Do you suffer from allergies to any medications or foods?
5. Are the episodes ever followed by a headache?
6. Do you mean when you closed the left eye, the right eye looked like a white-washed picket fence?
This information will help better evaluate your case...
