PURPOSE
The objective of this study was to compare the measurement of the optic nerve of the glaucomatous neuroretinal rim areas by planimetry and simple ophthalmoscopy.
METHODS
Studied were 49 randomly selected glaucomatous eyes. Their planimetric measurements of the optic nerve head and the neuroretinal rim were compared with an ophthalmoscopic measurement derived from the projection of the Welch Allyn 5 degrees illuminated cone. Axial length of the eyes was determined.
RESULTS
Utilizing regression equations, a correlation coefficient of 0.77 with a p value of < 0.0001 was obtained.
CONCLUSION
The simple ophthalmoscopic estimation of the optic nerve head size and the neuroretinal rim size in glaucomatous patients compared well with the more laborious planimetric techniques and might be helpful in evaluating optic nerve heads for glaucomatous abnormalities.
目的
本研究旨在比较通过平面测量法和简单检眼镜对青光眼神经视网膜边缘区域视神经的测量。
方法
研究了 49 只随机选择的青光眼眼。将其视神经头和神经视网膜边缘的平面测量值与 Welch Allyn 5 度照明锥的投影得出的检眼镜测量值进行比较。同时还测量了眼轴长度。
结果
利用回归方程，获得了相关系数为 0.77，p 值<0.0001。
结论
与更繁琐的平面测量技术相比，简单的检眼镜对青光眼患者的视神经头和神经视网膜边缘大小的估计与更费力的平面测量技术相比具有良好的相关性，并且可能有助于评估青光眼异常的视神经头。
