Which symptom is associated with excessive tear production?

Excessive tear production is specifically referred to as epiphora. This condition is characterized by an overflow of tears onto the face, often leading to wet fur around the eyes and potentially resulting in other secondary issues such as skin irritation.

Understanding the other choices can provide additional context. Conjunctivitis, an inflammation of the conjunctiva, can result from various causes, including infection or allergies, and may or may not be associated with excessive tears. Corneal ulcers involve erosion of the cornea and can be accompanied by tear production but do not directly indicate excessive tearing. Blepharitis, an inflammation of the eyelids, can cause qualitative or quantitative changes in tear production but is indicative of eyelid issues rather than an excess of tears.

Thus, the correct response reflects the condition that directly describes excessive tear production while others relate to different aspects of eye health.
