To describe uncommon techniques that induce compensatory strabismus utilizing slab-off spectacle prism to treat symptomatic incomitant vertical strabismus in adults with diplopia in the reading position only.
The medical records of consecutive patients having a chief complaint of diplopia in the reading position that was treated with slab-off prism correction were reviewed retrospectively. Success of the slab-off spectacle prism correction was determined at the follow-up visit or by phone call for any patients who did not return for a follow-up examination.
Five adult subjects were identified, ranging in age from 55 to 75 years (mean age, 65.6 years). All 5 patients complained of vertical diplopia during reading. Symptoms resolved with slab-off prism in all 5 cases. Three patients had symptomatic incomitant vertical strabismus occurring only in the reading position. All 3 of these patients remained in slab-off prism at in-office follow-up.
Slab-off spectacle prism in non-digitally manufactured multifocal lens prescriptions was an effective nonsurgical treatment option in this descriptive study of 5 patients with diplopia in the reading position only, 3 of whom had symptoms related to small-angle vertical strabismus in the reading position only, without anisometropia.
描述利用 slab-off 眼镜棱镜诱导补偿性斜视的不常见技术，以治疗仅在阅读位置出现复视的成人症状性非共同性垂直斜视。
回顾性分析了连续就诊的主诉为仅在阅读位置出现复视并接受 slab-off 棱镜矫正的患者的病历。在随访时或对未返回进行随访检查的任何患者进行电话随访，以确定 slab-off 眼镜棱镜矫正的效果。
共确定了 5 名年龄在 55 至 75 岁（平均年龄 65.6 岁）的成年患者。所有 5 例患者在阅读时均出现垂直复视症状。在所有 5 例中，症状均通过 slab-off 棱镜得到缓解。3 例患者仅在阅读位置出现有症状的非共同性垂直斜视。这 3 例患者在门诊随访时仍使用 slab-off 棱镜。
在本研究中，5 例仅在阅读位置出现复视的患者中，使用非数字制造的多焦点镜片处方中的 slab-off 眼镜棱镜是一种有效的非手术治疗选择，其中 3 例患者的症状仅与阅读位置的小角度垂直斜视有关，且无屈光不正。
