Trabeculectomy Following Failed Ab Interno Gelatin Microstent: Case Series.

Trabeculectomy following a failed XEN-45 implantation seems technically feasible; however, higher than expected number of cases with low IOP and avascular blebs were observed.

Applanation tonometry: interobserver and prism agreement using the reusable Goldmann applanation prism and the Tonosafe disposable prism.

There is an acceptable agreement between IOP measurements made with the reusable Goldmann tonometer prism and the disposable Tonosafe prism.

Interobserver agreement using Goldmann applanation tonometry and dynamic contour tonometry: comparing ophthalmologists, nurses and technicians.

Ophthalmologists show good levels of agreement with each other when using GAT, while technicians/nursing staff show better agreement when using the DCT.
