Though veno-occlusive disease is a recognized risk factor in flying, if the problem is vasculitic and not thrombotic, then flying should pose no risks and no preventive measures should be taken.
However, if your girlfriend has had surgeries involving injection of a bubble to keep the retina flat, this will expand at high altitudes. If this is the case, the airline should know to organize a low altitude flight.
Retinal hemorrhages (small areas of bleeding in the retina at the back of the eye) may develop after ascent to altitudes of 9,000 feet (2,700 meters). These hemorrhages are common above 16,000 feet (5,000 meters). People usually have no symptoms unless the hemorrhage occurs in the part of the eye that is responsible for central vision (the macula). In such cases, people may notice a small blind spot. Retinal hemorrhages resolve rapidly without causing long-term problems.

That depends on type, model and airline policy.
On our B737-800's cruise altitude on a 900 km trip would typically be 39000-41000 ft with a cabin altitude on around 6500 - 7000 ft.
