Fifty-four patients with a unilateral pigmented choroidal lesion were studied with electrooculography (EOG). Eighteen of 21 patients with histologically proven (13) or presumed (8) malignant tumors of the choroid had light peak-dark trough ratios (L/D) less than or equal to 150. Seventeen of 21 patients in the malignant group had an interocular L/D difference (L/Dd) greater than or equal to 23%, whereas only one of 33 patients with nevi or a condition simulating a nevus had a percent difference of such magnitude. Combining the L/D and L/Dd criteria resulted in a 98% accurate double-blind prediction of the final clinical/pathological results. The EOG is an objective, noninvasive test useful in the diagnosis of choroidal malignant melanomas.
对54例单侧色素性脉络膜病变患者进行了眼电图（EOG）检查。在21例经组织学证实（13例）或疑似（8例）脉络膜恶性肿瘤的患者中，有18例的光峰-暗谷比值（L/D）小于或等于150。恶性组21例患者中有17例的两眼间L/D差值（L/Dd）大于或等于23%，而在33例患有痣或疑似痣的患者中，只有1例的差值达到如此程度。将L/D和L/Dd标准相结合，对最终临床/病理结果的双盲预测准确率达98%。眼电图是一种客观、无创的检查方法，对脉络膜恶性黑色素瘤的诊断很有用。
