Safety and Efficacy of the Preserflo Microshunt in Refractory Glaucoma: A One-Year Study.

To evaluate the safety and efficacy of Preserflo microshunt implantation in eyes with refractory glaucoma. In this retrospective study, a cohort of patients who underwent Preserflo microshunt implantation between April 2019 and August 2020 for refractory glaucoma were evaluated. At the time of surgery, all eyes had uncontrolled intraocular pressure (IOP) despite maximally tolerated medical therapy and at least one previous failed glaucoma filtering surgery.

Transscleral filtration revealing a chorioretinal coloboma.

Purpose: We report the case of a 19-year-old patient who presented with an ocular hypotony due to a transscleral filtration through an isolated congenital chorioretinal coloboma in his right eye.

Observations: The initial examination showed a decimal best corrected visual acuity (BCVA) decreased to 0.7 and a marked hypotony.
