A method of measuring pupil-blocking force in the human eye.

摘要: A new method of measuring pupil-blocking force in the human eye is reported. The anterior segment was photographed using a slit-lamp apparatus and color photographs then analyzed with digitizer for converting optical image into true computer. This technique permits precise estimation relative positions chamber, such as pupil margins, iris root insertions, central anteroposterior pupillary axis. Pupil-blocking calculated from these data according to Hook's law. There statistically significant difference between normal subjects (mean ± SD, − 0.027 0.029λ; λ = Young's module) patients primary angle-closure glaucoma + 0.134 0.068λ) (P < 0.001). In glaucoma, during an acute attack markedly high. will provide valuable analysis mechanism glaucoma.
