You seem well-educated on your situation, and ask great questions.
It sounds as if only your right optic nerve is affected, and your headaches are not severe.
Diamox and weight loss for overweight individuals are typical first-line treatment approaches. You seem to have a true allergy to sulfa, and reactions to Diamox are a definite possibility. The cardiac drug Digoxin has been reported to lower the cerebrospinal pressure as well and has been beneficial for patients with your disease.
Another option if the nerve shows progressive damage is to have a surgery called optic nerve sheath fenestration to protect the nerve from raised intracranial pressure.
Let your neuro-ophthalmologist know of your allergy to Diamox and inquire about Digoxin.
Best of luck
You need to discuss this with your doctor. Most patients with sulfa allergies do not react to diamox in my experience.

My child took an antibiotic over a month ago for what we thought was a sinus infection. After an eye exam we found that her optic nerves are swollen bilaterally. The eye dr said the antibiotic could be making the nerves swollen. Is this true? thanks ccb04
