It is argued that (1) the work of Burt and Julesz does not challenge the classical notion of Panum's fusional area; (2) their disparity gradient concept is contradicted by some of their own findings as well as by those of Krol and van de Grind; (3) their results can be accounted for by the classical concept of Panum's fusional area if eye vergence is taken into account; (4) the explanations suggested by Burt and Julesz for the depth perception aspects of Panum's limiting case and the double-nail illusion are based on unwarranted generalisation of results concerning binocular direction vision.
（1）伯特和朱尔兹的研究并未对帕努姆融合区的经典概念构成挑战；（2）他们的视差梯度概念与他们自己的一些发现以及克罗尔和范德格林德的发现相矛盾；（3）如果考虑眼睛的辐辏，他们的结果可以用帕努姆融合区的经典概念来解释；（4）伯特和朱尔兹对帕努姆极限情况和双钉错觉的深度感知方面所提出的解释，是基于对双眼方向视觉结果的无端概括。
