Ah, sorry, didn't take note of the 'both eyes' reference in the title.
How much are they bulging? How fast did it come on? Is it a consistent amount or is it coming and going? Is it getting more pronounced? These are things to keep note of to tell your vet.
Glaucoma can be present in both eyes and it comes on pretty young.
Here's an excerpt from Susan Keil's great article on rabbit eyes, found here:
Rabbit Eyes By: Susan Keil, DVM, MS, DACVO

Glaucoma is a disease where an excessive intraocular pressure (IOP) causes damage to the retina. Blindness results when the IOP is too high for too long. Normal eye pressure is 15-25 mmHg. Glaucoma values can be interpreted as 26-95 mmHg. In New Zealand White (NZW) rabbits, the condition is inherited as an autosomal recessive trait. The onset of disease in the NZW is often between 3-6 months of age.
Clinical signs include buphthalmos (enlargement of the globe), generalized corneal edema (cornea appears blue), and blindness. Treatment of glaucoma is often frustrating. There are numerous topical medications (carbonic anhydrase inhibitors, prostaglandin antagonists, beta-blockers, parasympathomimetics) that can be utilized alone or in combination. Glaucoma is a disease that will require chronic medications and frequent rechecks. The target IOP for a visual eye with glaucoma is below 20-25 mmHg. If the IOP starts to rise, then additional medications will be recommended. The goal is to keep a visual eye visual.
Sometimes surgery may be recommended for either the visual (diode laser cycloablation, cyclocryoablation) or blind eye (enucleation, evisceration). Another option for a blind glaucoma eye is an injection of gentamicin antibiotic into the eye. This is called a chemical ablation. A chemical ablation "kills" the eye's ability to produce fluid. Without fluid production, the IOP drops permanently. The goal with a blind glaucoma eye is to keep the eye comfortable. Pressures below 35-40 mmHg are considered comfortable.
And of course MediRabbit is always good for information, although I do think in in this area, they confuse and scare people on this page with a pretty dire prognosis re: eye abscesses.

But abscesses causing a bulging eye (most often dental related) are treatable with aggressive oral and injected antibiotics, and if that doesn't work, then surgery.
Did she show any signs of a dental issue, ear infection, etc? Did her eating habits change? Maybe a double abscess from a mouthful of bad teeth?
I would think the Vet would be inclined to try an aggressive regiment of both oral and injected antibiotics and/or surgical removal of the abscess (and the eye depending on the location).
My vet uses some form of injected penicillin (PenG or Bicillin) and oral ChlorPalm. Zithromax is also a good bet but this sort of thing I imagine will require a culture and sensitivity test ASAP if an infection is confirmed.
I'm not sure what kind of a chest mass would be all that common in an 18-month old rabbit, but as per the previous post, something else to think about. I did read about a case where a respiratory infection caused both eyes to bulge.
Obviously a vet issue whatever.
I hope she's okay. Pretty rabbit.
