OBJECTIVE: To compare the value of pattern electroretinograms (P-ERG), pattern reversal visual evoked potentials (P-VEP), light sensitivity in the central visual field, and blood flow velocity of the ocular blood vessels in early primary glaucoma. METHODS: Two hundred and thirty eyes of 128 patients with early primary glaucoma and 96 eyes of 48 normal volunteers were examined by the four methods. The susceptibility, peculiarity, and diagnostic index of the four methods were statistically measured and inspected. RESULTS: The difference between the glaucoma and normal groups was significant for all four methods (p < 0.01). The value of the four methods in the early diagnosis of primary glaucoma is P-ERG > P-VEP > light sensitivity > blood flow velocity of arteries. CONCLUSIONS: The examination of P-ERG, P-VEP, and light sensitivity had greater value than that of blood flow velocity of the ocular blood vessel for the early diagnosis of primary glaucoma.
