Abstract
- Laser scanning tomography is an accurate method for the three-dimentional assessment of the optic nerve head. But its topographic measurement should be highly reproducible for early diagnosis and follow-up of patients with glaucoma. The authors evaluated the reproducibility of optic nerve head topographic measurements by the Heidelberg retina tomograph(HRT). The mean standard deviation of height measurements and the mean coefficient of variation of each parameters were calculated on the 10 independent measurements in five normal eyes. The results showed that the mean standard deviation of height measurements was 29.19 microgram. The mean coefficient of variation of the cup area, rim area, rim volume, mean cup depth and the mean retinal nerve fiber layer thickness was under 10%. Optic nerve head topographic measurement by the HRT is highly reprooucible, which may help follow-up of glaucoma patients.
