To reduce intraocular concentrations of mitomycin-C (MMC), the authors used a scleral shield instead of a surgical sponge for the application of MMC during surgery.
A total of 20 patients were operated on using the scleral shield with MMC. These patients were observed for 6 months postoperatively.
The rate of hypotony was 25% (5 of 20 patients). Visual acuity was not markedly reduced, and no case of hypotony maculopathy developed. The success rate and complications were not different from those of previous studies using the surgical sponge.
The scleral shield may be advantageous for reducing the rate of hypotony maculopathy.
为降低丝裂霉素C（MMC）的眼内浓度，作者在手术中使用巩膜屏障而非手术海绵来应用MMC。
共有20例患者使用含MMC的巩膜屏障进行手术。对这些患者术后进行了6个月的观察。
低眼压发生率为25%（20例患者中有5例）。视力未明显下降，且未发生低眼压性黄斑病变。成功率和并发症与先前使用手术海绵的研究无异。
巩膜屏障可能有利于降低低眼压性黄斑病变的发生率。
