Abstract	「要約」【目的】JACO Stereo Test(以下JACO), TNO Stereo Test(以下TNO), Stereo Fly Test(以下FLY)の有用性を比較検討した. 【対象と方法】対象は, 斜視や弱視およびその治療歴がない成人ボランティア45例である. 方法は, 視力, 屈折, 眼位, 優位眼の同定, 立体視, 抑制検査を行った. なお立体視の判定は, 中心窩立体視60秒以下を正常とした. 【結果】平均矯正視力は, 右眼1.19, 左眼1.19, 平均屈折度数は-2.49±2.49Dであった. 立体視は, JACO42例(93.3%), TNO24例(53.3%), FLY45例(100%)で, 3種の検査表間に有意差を認めた(P<0.0001). さらに多重比較ではJACOとTNO間, TNOとFLY間に有意差を認め(p<0.0001), JACOとFLY間では有意差を認めなかった(p=0.10). 全検査表で抑制応答はなかったが, JACOの抑制検出視標では, 「円形視標が立体的に側方へずれて一つに見える」と応答した例が, 0.5度視標15例(33.3%), 1.0度視標13例(28.9%)にみられた. これは, ずれ応答と優位眼とがほぼ一致する結果であった. 【結論】3種の検査表では, TNOのみ立体視の検出率が低かった. JACOの抑制検出視標では, 優位眼による影響が応答に反映している可能性が示された.

Abstract	[Abstract] [Purpose] We assessed and compared the usefulness of three stereo tests, JACO Stereo Test (JACO), TNO Stereo Test (TNO), and Stereo Fly Test (FLY). [Subjects and Methods] Subjects were 45 healthy volunteers who had no history of eye disease, strabismus or amblyopia. Testing for visual acuity, refraction, eye position, eye dominance determination, stereopsis, and suppression using the three stereo tests was all performed. Stereoacuity of <=60 seconds of arc was considered normal. [Results] The average measurements of corrected visual acuity were 1.19 for the right eye and 1.19 for the left eye. The average refraction was -2.49 +- 2.49 D. The numbers of subjects showing normal stereopsis were 42 (93.3%) subjects by JACO, 24 (53.3%) subjects for TNO, and 45 (100%) subjects for FLY. A significant difference was seen among the three tests (P<0.0001). By multiple comparison, significant differences were seen between JACO and TNO and between TNO and FLY (P<0.0001), but not between JACO and FLY (P = 0.10). No test detected suppression in the subjects. However, in the JACO test for suppression, 15 (33.3%) subjects tested with 0.5° test target and 13 (28.9%) subjects tested with 1° test target indicated "The circular test targets appeared three-dimensional, deviated to one side, and were seen as one single target". This showed the corresponded response for deviation and result for eye dominance. [Conclusions] Among the three tests, only TNO showed a low detection rate of stereopsis. In the JACO test for suppression, possible influence of eye dominance on the test response was observed.
