OBJECTIVE: To study the consistency between optic disc neural rim depth (NRD) and visual field defects in patients with primary open-angle glaucoma (POAG). METHODS: A system of computerized image analysis was used to measure the relative NRDs of temporal-superior and temporal-inferior area of the optic disc in patients with POAG. The consistency between the area with relatively larger NRD and the location of more severe visual field defects was investigated. RESULTS: In cases with early and middle-stage POAG, the value of NRD corresponding to the location of more severe visual field defects was significantly larger than that corresponding to the location of no or mild such defects. In 54 eyes, there were 46 whose location with a larger NRD value was consistent to the position of more severe visual field defects, the rate of consistency being 85.2%. CONCLUSIONS: In cases with early and middle-stage POAG, the increase of NRD value at the temporal-superior and temporal-inferior area is asymmetrical, and the consistency between the area with a larger NRD value and the corresponding position of more severe visual field defects is relatively high. NRD is helpful in the early diagnosis of POAG.LA: Chinese
