Final answer:
Severe Giant Papillary Conjunctivitis causing eyelid ptosis is classified as mechanical blepharoptosis, resulting from the mass of inflamed tissue.
Step-by-step explanation:
The condition of eyelid ptosis that occurs as a result of severe Giant Papillary Conjunctivitis (GPC) can be classified as mechanical blepharoptosis. This type of ptosis is due to the physical weight or bulk of inflamed tissue pressing down and causing the eyelid to droop. GPC itself is an inflammatory condition characterized by large papillae on the inner eyelids, commonly associated with long-term contact lens wear, and it involves the mechanical disruption of normal eyelid function.
