(A) Spontaneous tear volume was reduced ipsilateral to exorbital gland removal at 14 days after surgery. Tear volume measured over 2 minutes under isoflurane or urethane anesthesia. Sample sizes (rats per group): sham, n = 48; 14d DE, n = 41. **P < 0.01 vs ipsilateral; b = P < 0.01 vs sham. (B) Eye blink behavior was evoked by 0.15, 1, and 2.5 M NaCl before surgery (day 0) and at 2, 5, 7, and 14 days after exorbital gland removal. **P < 0.01 vs presurgery; a = P < 0.05, b = P < 0.01 vs response to 0.15 M saline; n = 4.
