Outcomes of Trabeculectomy and Glaucoma Drainage Devices for Elevated Intraocular Pressure After Penetrating Keratoplasty

Purpose: To assess and compare the outcomes of trabeculectomy with and without antimetabolites (AMs) and glaucoma drainage devices (GDDs) in the management of elevated intraocular pressure (IOP) after penetrating keratoplasty (PK). Methods: Data of 84 eyes of 81 patients who underwent trabeculectomy (12 eyes without an AM and 42 eyes with an AM) or GDD implantation (30 eyes) after PK were reviewed retrospectively. The main outcome measures were IOP control, corneal graft survival, and postoperative ocular complications. Results: At the final visit, IOP success (

CONCLUSIONS: Though malignant glaucoma is highly refractory to treatment, appropriate management in the form of medical or vitrectomy-hyaloidotomy-zonulectomy-iridotomy could achieve 90% success in this series. PMID: 31587568 [PubMed - as supplied by publisher]

Conclusions: There was no reduction in donor dislocation or SGF in eyes with PP compared with AC GDD, despite the decreased proximity of the shunt from the endothelial graft. Overall, GDD has a significantly adverse effect on long-term graft survival and close follow-up is warranted.

Conclusions: The 2-year results indicate that there is a place for the Boston type 1 KPro in the management of corneal blindness. However, there is scarce evidence regarding its medium- and long-term efficacy and safety. The high rate of reported complications necessitates strict patient selection and stringent follow-up.

Conclusions: The frequency of GDDs as a reason for keratoplasty has not changed significantly between 10 years in this tertiary care setting. Patients with GDDs who later required keratoplasty had associated features including multiple surgical procedures and comorbid infection, pseudophakic bullous keratopathy, Fuchs dystrophy, pseudoexfoliation, uveitis, and congenital glaucoma.

CONCLUSIONS: Presence of a GDD adversely affects graft survival whereas glaucomatous eyes which were medically managed or surgically managed without a GDD had survival rates comparable to controls. Glaucoma-filtering surgeries may confer graft survival advantage over tube shunt surgeries after DSEK. PMID: 31564348 [PubMed - in process]

CONCLUSIONS: UV-riboflavin cross-linking of the corneal tissue patch graft material appears to be a safe modification when used in GDDS and warrants ongoing study. This method of patch graft can replace other costy methods used with GDD.

Conclusion: Preterm babies have thick corneas and small corneal diameters. This study is useful with respect to the analysis of glaucoma in children and using preterm corneas as donor corneas in penetrating keratoplasty.

Conclusion: Repeat DSAEK is feasible in up to two-third of cases of failed DSAEK. A PKP is required in one-third of cases, and various preoperative, intraoperative and postoperative factors are associated with unsuitability for repeat DSAEK.

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...
