To investigate the feasibility, acceptability, efficacy, and cost of a newly developed translucent shield that can be fixed by sutures to the orbital rim for a month of amblyopia therapy.
In an institutional review board-approved protocol for patients with amblyopia who do not adhere to the use of conventional patching, shield occluders were fashioned from heat-moldable sturdy black or translucent (20/4000) plastic with holes drilled for attachment. Under brief general anesthesia, patients aged 5 to 10 years had a thorough examination before the shield occluder was sewn to the brow and cheek of the nonamblyopic eye with 3-0 monofilament polypropylene sutures.
Ten children completed this protocol from December 1999 through January 2002. All tolerated the occluder for 12 to 36 days. The resultant skin scars were acceptable to parents, patients, and investigators. The amblyopic eyes improved from a mean (SD) of 0.77 (0.30) logMAR (Snellen equivalent, 20/119) to 0.45 (0.29) logMAR (Snellen equivalent, 20/57), a change of 0.32 (0.16) logMAR lines. There was no damage to the sound (occluded) eye.
Sew-on occluder shields are an alternative when adherence to the use of other types of patching (often referred to as compliance with patching) is not satisfactory.
研究一种新开发的可通过缝合固定于眼眶边缘用于弱视治疗1个月的半透明眼罩的可行性、可接受性、疗效及成本。
在机构审查委员会批准的针对不坚持使用传统眼罩的弱视患者的方案中，眼罩由可热成型的坚固黑色或半透明（20/4000）塑料制成，并钻孔以便固定。在短暂全身麻醉下，5至10岁的患者在将眼罩用3-0单丝聚丙烯缝线缝至非弱视眼的眉部和脸颊之前进行了全面检查。
从1999年12月至2002年1月，10名儿童完成了该方案。所有患者均耐受眼罩12至36天。由此产生的皮肤瘢痕对于家长、患者和研究者来说是可接受的。弱视眼的视力从平均（标准差）0.77（0.30）logMAR（Snellen等效值，20/119）提高到0.45（0.29）logMAR（Snellen等效值，20/57），变化了0.32（0.16）logMAR行。未对健眼造成损害。
当坚持使用其他类型的眼罩（通常称为眼罩依从性）不理想时，缝合式眼罩是一种替代方法。
