There is a significant decrease in the accommodation to hyperpolarizing currents on the affected side of patients In A there was a significantly greater change in threshold in response to hyperpolarizing currents for the affected side of patients (P = 0.021, mean ± s.e.m.). B, the mean (± s.e.m.) of the slope of the current–threshold relationship for the first 6 points (−10 to −60%) in the hyperpolarizing direction. The difference in values for the two sides of the patients was significant but the values for the unaffected side (n = 11) were similar to the control values (n = 12).
