An otherwise healthy 35 year old obese woman with a recent weight gain presents to your office complaining of headaches, which are increasing in frequency and severity.  She also complains of tinnitus and a brief bilateral loss of vision which lasted for about 5 seconds.

Her visual acuity is 20/20 OU, visual fields normal to confrontation, pupils equal in size and reactivity to light, and normal extraocular movements.   Fundus examination (shown below) is similar bilaterally.  You also do a complete neurological exam, which reveals no abnormality.
