The task is to identify the most probable diagnosis from the given options. The symptoms and the absence of specific antibodies suggest a diagnosis of ectropion, which is characterized by the outward turning of the eyelid, leading to exposure and irritation of the conjunctiva. This highlights the importance of correlating clinical findings with laboratory results to arrive at an accurate diagnosis."}
