Purpose: To observe the characteristics of pupillary light reflex in the patients with retrobulbar neuritis. Methods:Twenty–two patients (thirty eyes with the retrobulbar neuritis) aged between ten and fifty–eight years were examined using a automatic pupillometer. Results:The latency of the pupillary light reflex was delayed, the maximum amplitude of the pupillary light reflex was decreased in patients with retrobulbar neuritis in acute stage. There was also statistical difference in the two above parameters between the patients in recovery stage and normal subjects. Conclusions:As a way to reflect the visual function, the pupil test correctly and objectively provides quantitative information about the pupillary light reflex. The pupil test is helpful to observe the functions of retinal and optic nerve disease.
