Final answer:
Graves ophthalmopathy is the type of infiltrative ophthalmopathy that causes increased fat deposits and edema in the retroorbital tissues, forcing the eyeballs outward.
Step-by-step explanation:
The type of infiltrative ophthalmopathy due to impaired venous drainage from the orbit that causes increased fat deposits and edema in the retroorbital tissues, forcing the eyeballs outward is known as Graves ophthalmopathy. It is a condition associated with Graves disease, an autoimmune disorder that affects the thyroid gland. In Graves ophthalmopathy, the swelling of retroorbital tissues impairs venous drainage, resulting in the accumulation of fat and edema, which pushes the eyeballs forward.
