项目摘要

The purpose of the present study is to clarify the defects of color perception and of binocular vision in the post operative newly seeing person or in children of low vision, and to follow up, over a long period, the processes of acquisition and development of these functions mentioned above under the medical treatment and psychological training. The research had been conducted from April of 1986 to March of 1988, in cooperation with Subs. YY and KT who were born with cataract in both eyes and successfully operated upon, Sub. B who was a child of low vision, and Sub. A who suffered from intracranial hemorrhage due to AVM.The main results obtained are as follows. (1) Incrementthreshold spectral sensitivity of Subs. YY and H taken with a 1000td background showed three peaks through ghe visible spectrum at 440(or 450)nm, 520nm and 600nm. They are found also in the spectral sensitivity curve obtained in subjects of normal trichromat, while only two peaks are found in the spectral sensitivity curve obtained in protanope and deuteranope (at 440 and 550nm, and 440 and 580nm, respectively). (2) All the same, neither Sub. YY and Sub. H could not recognize almost all figures in Ishihara's Test for Color-Blindness. Neither did Sub. A. (3) These three subjects were found to be able to identify colors of colored papers. (4) On the one hand, Sub. H (a crippled child with visual acuity of 0.1 and 0.4 in right and left eyes, respectively) has attained tgo get the ability of stereoscopic vision which thus far he had not been thought to have, as far as with the classic stereogram on which some drawing were depicted. (2) On the other hadn, so far, it has been difficult for Sub. H to see depth with random-dot stereogram.

本研究的目的是阐明术后复明者或低视力儿童的色觉和双眼视功能缺陷，并长期跟踪观察在药物治疗和心理训练下这些功能的获得和发展过程。这项研究是在1986年4月至1988年3月与Subs合作进行的。YY和KT出生时双眼均患有白内障，手术成功，Sub。B是一个低视力的孩子，还有Sub。本文报告一例脑动静脉畸形颅内出血患者。(1)Subs的增量阈值光谱灵敏度。在1000td背景下，YY和H的可见光谱在440（或450）nm、520 nm和600 nm处有三个峰。在正常三色视者的光谱灵敏度曲线中也发现了它们，而在原色盲和氘色盲的光谱灵敏度曲线中只发现了两个峰（分别在440和550 nm，以及440和580 nm）。(2)都一样，也不是潜艇。YY和Sub。在石原的色盲测试中，H几乎认不出所有的数字。Sub也没有。A. (3)这三名受试者被发现能够识别彩色纸的颜色。(4)一方面，子。H（一个残疾儿童，右眼和左眼的视力分别为0.1和0.4）已经获得了立体视觉的能力，这是迄今为止人们认为他没有的，就像经典的立体图上描绘的那样。(2)另一方面，到目前为止，这对潜艇来说很困难。用随机点立体图看深度。
