PURPOSE
To design a chart for drawing retinal detachments that minimizes the circumferential distortion that occurs with the current chart.
METHODS
After trying several standard map projections, a hybrid chart was created. It retains the radial equidistant projection of the current chart from the posterior pole to the equator, but superimposes stereographic projection anterior to the equator. The hybrid chart was put on trial for drawing retinal lesions and planning retinal detachment surgery at the New York Hospital and at the University Eye Clinic in Tübingen in May 1992.
RESULTS
The stereographic projection anterior to the equator has minimized the distortion of retinal breaks and other pathology in the anterior retina when drawn on the chart. Retinal breaks can be drawn as they are seen ophthalmoscopically and estimates of their real dimensions derived from the chart.
CONCLUSION
A new retinal chart that minimizes circumferential distortion anterior to the equator has proven advantages for planning retinal detachment surgery.
目的
设计一种用于绘制视网膜脱离的图表，以尽量减少当前图表所出现的圆周变形。
方法
在尝试了几种标准地图投影后，创建了一种混合图表。它保留了当前图表从后极到赤道的径向等距投影，但在赤道前方叠加了立体投影。1992年5月，在纽约医院和图宾根大学眼科诊所对该混合图表进行了绘制视网膜病变和规划视网膜脱离手术的试验。
结果
赤道前方的立体投影在图表上绘制时，已将视网膜裂孔和视网膜前部其他病变的变形降至最低。视网膜裂孔可以按检眼镜下所见进行绘制，并可从图表得出其实际尺寸的估计值。
结论
一种能将赤道前方的圆周变形降至最低的新型视网膜图表，已证明在规划视网膜脱离手术方面具有优势。
