Methods: This prospective trial involved 23 eyes of 16 consecutive patients with uncontrolled open angle glaucoma. The DSCI procedure involved radial suturing of a 2mm piece of 1/0 chromic suture as an implant. Intraocular pressure (IOP) measurements and eye examinations were performed preoperatively and regularly postoperatively for up to 66 months. Results: The mean follow-up period was 36.3 (SD 19.9)-months. The mean preoperative IOPwas 26.3 (SD 8.5)mmHg. Themean postoperative IOPwas 14.1 (SD 2.8)mmHg atmonth 12, and 16.5 (SD 2.3)mmHg at 36 months. Complete success rate, defined as an IOPlower than 21mmHg without medication was 77%of eyes at 36 months. Qualified success rate, defined as an IOPl ower than 21mmHg with medication, was 100%at 36 months. Paired t-test andWilcoxon test analysis of preoperative vs postoperative IOPat 36 months indicated a significant reduction in IOP, Intraoperative complications included rupture of the trabecular meshwork in seven eyes. Exclusion of these patients from the results analysis revealed a mean follow-up of 37.1 months (SD 9), preoperative mean IOPwas 25.9mmHg (SD 4.1), 12-month mean IOPwas 13.4mmHg (SD 2.8), and 36-month mean IOP16.6mmHg (SD 2.1). Early postoperative complications included hyphaema in two eyes and dislocation of implant in one eye. One eye developed a central retinal vein occlusion and cataract progression occurred in one eye. The mean postoperative duration of use of topical dexamethasone was 5.4 months (SD 2). Conclusions: DSCI using a chromic suture implant provides good control of IOPat medium-term follow-upwith fewpostoperative complications. Prolonged use of postoperative anti-inflammatory medication was necessary.展开更多

DESIGN: Interventional case report. METHODS: A sixyear-old girl underwent corneal tattooing (platinum chloride reduced by hydrazine) in the relevant scarred corneal sector. RESULTS: Six months after the procedure, the child enjoyed a more normal corneal appearance and no longer suffered from glare. Postoperative epithelial healing, however, was slow and required vigilance. CONCLUSIONS: Corneal tattooing can allow both cosmetic and therapeutic benefit when indicated in a child. However, postoperative healing may require management when using platinum chloride reduced by hydrazine.展开更多
