摘　　要：目的:探讨15Δ三棱镜诱发眼斜诊断弱视的作用。方法:采用双盲法检查278例儿童视力和用15Δ三棱镜诱发眼斜检查确定注视类型,并比较结果。结果:①53例用15Δ三棱镜诱发眼斜检查确定为双眼持续注视,其双眼视力相等,46例双眼视力均为1.0,7例视力为1.0-2￣-3;②51例用15Δ三棱镜诱发眼斜检查确定为轻度弱视的患者中,44例双眼视力相差两行或少于两行,视力为0.6￣0.8;7例双眼视力相差两行以上,视力为0.4￣0.5;③122例用15Δ三棱镜诱发眼斜检查确定为明显弱视的患者双眼视力相差两行以上,视力均在0.2￣0.5之间,与我国中度弱视视力诊断标准相符合;④31例用15Δ三棱镜诱发眼斜检查确定为重度弱视患者视力均低于0.1;⑤21例用15Δ三棱镜诱发眼斜检查确定为双眼持续注视,其双眼视力相等,但双眼视力为0.6￣0.8;⑥用检查视力和15Δ三棱镜诱发眼斜两种方法诊断弱视的符合率为92.4%(257/278)。结论:15Δ三棱镜诱发眼斜检查确定注视类型,提高弱视的诊断率,使早期治疗弱视成为可能。Objective： To study the reliability of 15^Δ prism inducing deviation in diagnosing of amblyopia. Methods： The visual acuity was examined by bilateral blind method and the fixation patterns were detected with 15-diopter （15D） base-down prism-inducing deviation in 278 children. Results： By 15D base-down prism-inducing deviation, .74 cases had bilateral maintained fixation and equal vision, of which 46 had the vision of 1.0, 7 had the vision of 1.0^-2-3, while 21 had the vision between 0.6～0.8; 51 cases had mild amblyopia, of them, 44 had the two eyes two or less lines different between 0.6～0.8, 7 had the two eyes more than two lines different between 0.4～0.5; 122 cases had marked amblyopia with the two eyes more than two-line different between 0.2～0.5; 31 cases had severe amblyopia with the visions less than 0.1. The coincident rate of amblyopia diagnosis with checking visual acuity and 15D base-down prism-inducing deviation was 92.4%（257/278）. Conclusion： 15D prism-inducing deviation test for fixation pattern is an easy and reliable method for diagnosis of amblyopia. It makes possibility for early treatment of amblyopia.
