Suprachoroidal Bleeding After XEN Gel Implantation

2017

Purpose To report for the first time a clinical case of suprachoroidal bleeding after XEN45 gel implantation. Observations A 84-year old female patient with pseudoexfoliation glaucoma with intraocular pressure (IOP) (20 mm Hg) above target despite maximal IOP-lowering therapy was scheduled for XEN45 gel implantation. The XEN45 gel implantation went without complications and was properly placed in the anterior chamber and beneath the conjunctiva. On the first postoperative day, the patient presented with an IOP of 4 mm Hg, a functioning bleb and a deep anterior chamber. On the second day she developed suprachoroidal bleeding. A wait and see strategy was followed and the patient monitored ste…

What Do We Really Know about the Effectiveness of Glaucoma Interventions?

2021

Purpose To identify systematic reviews of interventions for glaucoma conditions and to assess their reliability, thereby generating a list of potentially reliable reviews for updating glaucoma practice guidelines. Design Cross-sectional study. Participants Systematic reviews of interventions for glaucoma conditions. Methods We used a database of systematic reviews and meta-analyses in vision research and eye care maintained by the Cochrane Eyes and Vision United States Satellite. We examined all Cochrane systematic reviews of interventions for glaucoma conditions published before August 7, 2019, and all non-Cochrane systematic reviews of interventions for glaucoma conditions published betwe…

Canaloplasty with mitomycin C after previous combined cataract surgery and Schlemm's canal microstent implantation.

2021

We report on a 56-year-old male with primary open-angle glaucoma who underwent mitomycin C augmented canaloplasty enabling filtration in the right eye after cataract surgery combined with a Schlemm’s canal microstent 3 years previously. He showed progressive glaucomatous optic neuropathy and was highly myopic (axial length 32.05 mm, spherical equivalent −18.75 dioptres in the right eye). Augmented canaloplasty was performed uneventfully and 360° catheterisation was achieved followed by the placement of a 10-0 polypropylene suture in Schlemm’s canal. Intraocular pressure (IOP) in the first post-operative day was reduced from 19 to 6 mmHg. At 1-month follow-up IOP was 12 mmHg off glaucoma me…

Results of an Adaptive Surgical Approach for Managing Late Onset Hypotony After Trabeculectomy With Mitomycin C.

2018

OBJECTIVES The objective of this study is to investigate the results of an adaptive approach of bleb revision surgery for late onset hypotony after trabeculectomy with mitomycin C because of bleb leakage and/or scleral melting. METHODS A total of 29 eyes of 27 patients, aged 63.8±11.7 years with hypotony maculopathy [intraocular pressure (IOP), ≤6 mm Hg] because of late onset bleb leakage and/or scleral melting after trabeculectomy with mitomycin C in which minimally invasive transconjunctival suturing of the scleral flap was impossible were enrolled in this retrospective interventional case series. External bleb leakage was seen in 16 eyes, 11 eyes suffered from scleral melting. Because of…

2020

Prcis Treatment of leakage with ocular hypotony after trabeculectomy with mitomycin C (MMC) can be safely achieved through conjunctival patch alone or combined with donor scleral graft in cases of melted underlying sclera. Purpose To report outcomes of 2 surgical approaches for treating ocular hypotony in eyes with blebs with late-onset leakage after standard trabeculectomy with MMC. Methods Thirty consecutive cases with bleb leakage and hypotony underwent bleb revision surgery between 2009 and 2014 by the same surgeon (J.W.) at the Department of Ophthalmology of the Mainz University Medical Center, Germany. In 18 patients, an autologous conjunctival patch graft was applied. In 12 patients,…

Schwankungen des Augeninnendrucks, Blutdrucks und okulären Perfusionsdrucks bei Glaukompatienten

2015

Hintergrund: Neben dem erhohten Augeninnendruck als Hauptrisikofaktor fur Entstehen und Fortschreiten des Glaukoms wird Schwankungen des Augeninnendrucks, Blutdrucks und okularen Perfusionsdrucks eine zunehmende Rolle zugesprochen. Uber den Einfluss von antiglaukomatosen Augentropfen auf diese Parameter ist wenig bekannt. Diese Studie untersucht 1) den Zusammenhang zwischen Schwankungen des Augeninnendrucks, Blutdrucks und okularen Perfusionsdrucks und der Schwere der glaukomatosen Erkrankung sowie 2) inwieweit diese Parameter durch unterschiedliche antiglaukomatose Augentropfen beeinflusst werden. Material und Methoden: Daten von 121 Glaukompatienten, die zwischen 2003 und 2012 ein station…

Spontaneous Resolution of Delayed Suprachoroidal Hemorrhage in the Single Eye Following Needling in Congenital Glaucoma

2017

Suprachoroidal hemorrhage (SCH) is a rare, but potentially vision-threatening event with poor long-term visual prognosis. At present, there is disagreement whether surgical intervention or conservative treatment is superior in the management. We report on a case of spontaneous resolution of severe SCH after needling procedure in the only eye of a young patient with congenital glaucoma.A 43-year-old woman with congenital glaucoma was scheduled for bleb needling in her only eye. Preoperative best-corrected visual acuity was 20/40 and intraocular pressure 20 mm Hg. On the third postoperative day, she developed a massive delayed SCH with appositional (kissing) choroidal bullae and visual acuity…

A New Method for Revision of Encapsulated Blebs after Trabeculectomy: Combination of Standard Bleb Needling with Transconjunctival Scleral Flap Sutur…

2016

Purpose A simple needling procedure is the standard method for restoring the function of an encapsulated bleb after trabeculectomy. However, postoperative hypotony represents a possible hazard. This study describes a new surgical approach for treating encapsulated blebs with reduced risk of early postoperative hypotony: bleb needling combined with transconjunctival sutures tightening the scleral flap directly. Methods The study included two groups of 23 patients with failing bleb following trabeculectomy: “Group 1” underwent simple needling revision of the filtering bleb and served as a control group, while “Group 2” received needling revision with additional transconjunctival scleral flap …

XEN-augmented Baerveldt Implantation for Refractory Childhood Glaucoma: A Retrospective Case Series

2019

Background Tube implants can lead to long-term decompensation of the cornea after decades, in particular in complicated childhood glaucoma, because of a variety of causes including contact between the tube tip and the corneal endothelium. The augmentation of a XEN implant with a Baerveldt (250) tube implant, introduced 2016 by Mermoud et al for refractory glaucoma in adult patients, may reduce this risk in children. In our retrospective study, we report on the XEN-augmented Baerveldt (250) tube implant in children. Patients and methods Ten consecutive patients with refractory childhood glaucoma who underwent XEN-augmented Baerveldt implantation by a single surgeon (F.G.) between January 201…

Urrets-Zavalia Syndrome After Combined Trabeculotomy-Trabeculectomy Surgery

2018

We report a case of a rare complication after trabeculotomy combined with a small trabeculectomy with mitomycin C in a young patient with juvenile glaucoma. The patient underwent uneventful surgery. However, postoperatively, he experienced a long-lasting hypotony with the need of 2 revision surgeries and 2 short episodes of high-intraocular pressure. He developed a fixed dilated pupil over time.

Alterations in Tight- and Adherens-Junction Proteins Related to Glaucoma Mimicked in the Organotypically Cultivated Mouse Retina Under Elevated Press…

2020

Purpose To scrutinize alterations in cellular interactions and cell signaling in the glaucomatous retina, mouse retinal explants were exposed to elevated pressure. Methods Retinal explants were prepared from C57bl6 mice and cultivated in a pressure chamber under normotensive (atmospheric pressure + 0 mm Hg), moderately elevated (30 mm Hg), and highly elevated (60 mm Hg) pressure conditions. The expression levels of proteins involved in the formation of tight junctions (zonula occludens 1 [ZO-1], occludin, and claudin-5) and adherens junctions (VE-cadherin and β-catenin) and in cell-signaling cascades (Cdc42 and activated Cdc42 kinase 1 [ACK1]), as well as the expression levels of the growth…
