Results of different strategies to manage complicated retinal re-detachment.

Purpose: Complicated retinal re-detachment with inferior proliferative vitreoretinopathy (PVR) remains a challenge. This study's aim was to compare vitrectomy with conventional silicon oil (CSO) combined with an encircling band (EB) and vitrectomy with heavy silicon oil (HSO) alone to treat retinal re-detachment through inferior PVR, where standard procedures have already failed.

Methods: A retrospective analysis was done on patients with inferior complex re-detachment with secondary PVR after primary surgery, who received pars plana vitrectomy (PPV) with CSO combined with EB (group 1) or PPV alone with HSO (group 2) between December 2006 and August 2017.

New retinal tack designs: an analysis of retention forces in human scleral tissue.

Purpose: The study aimed to construct a new retinal tack design with high retention forces to prevent spontaneous disentanglement in cases of complicated retinal surgery.

Methods: Six new forms for the peak of a retinal tack were developed using computer-aided design (CAD); then a prototype was produced for each model. Finally, standardised design testing was conducted using human (ex vivo) sclera by logging 15 consecutive measurements for each model.

PROSPECTIVE RANDOMIZED TRIAL ASSESSING THE IMPACT OF FEEDBACK MECHANISMS ON PATIENT POSITIONING.

Purpose: To investigate the use of a head-fixed feedback sensor to improve good positioning times after macular hole or retinal detachment surgery. The instructional methods, macular hole closure rates, and questionnaire responses were also evaluated.

Methods: After randomization, sensor devices with different feedback types (none/acoustic/vibration) were fixed on the patients' heads.

Comparison of ab externo trabeculotomy in primary open-angle glaucoma and uveitic glaucoma: long-term outcomes.

Background: The aim of this study was to compare the long-term outcomes of ab externo trabeculotomy in primary open-angle glaucoma (POAG) and uveitic glaucoma (UG).

Design: This was a retrospective single-center case series study.

Participants: Twenty eyes of 17 patients with POAG and 22 eyes of 18 patients with UG were included in this study.

Outcomes of Ahmed Glaucoma Valve Implantation for Glaucoma Secondary to Fuchs Uveitis Syndrome.

Purpose: To present the outcomes of Ahmed glaucoma valve implantation (AGV) in glaucoma secondary to Fuchs uveitis syndrome (FUS).

Methods: In this retrospective chart review, two definitions of success were used: 6 mmHg ≤intraocular pressure (IOP) ≤21 mmHg (success 1), and 6 mmHg ≤ IOP ≤21 mmHg and at least 25% reduction from baseline (success 2). Depending on the need of postoperative antiglaucoma medication, success was defined as either complete or qualified.

Long-term results of ab externo trabeculotomy for glaucoma secondary to chronic uveitis.

Purpose: To present the long-term results of ab externo trabeculotomy in the management of glaucoma secondary to chronic uveitis.

Methods: In this retrospective single-centre case series, medical records of patients with glaucoma secondary to chronic uveitis, who underwent ab externo trabeculotomy, were evaluated. Two definitions of success were used: intraocular pressure (IOP) 6 ≤ IOP ≤ 21 mmHg (success 1) or 6 ≤ IOP ≤ 21 mmHg and at least 25 % reduction from baseline (success 2).

Submacular predominantly hemorrhagic choroidal neovascularization: resolution of bleedings under anti-VEGF therapy.

Purpose: To report the visual and morphological outcomes following intravitreal bevacizumab in neovascular age-related macular degeneration (nAMD) with submacular, predominantly hemorrhagic, lesions.

Methods: Retrospective study of patients with a follow-up after 1 year. All eyes with submacular hemorrhages larger than 50% of the total lesion size and received only anti-VEGF (vascular endothelial growth factor) monotherapy (intravitreous administration of 1.

Exit strategies in canaloplasty: intraoperative conversion into 180-degree trabeculotomy or 360-degree trabeculotomy in cases of unsuccessful catheterisation of Schlemm's canal: influence of degree of canal cleavage.

Purpose: To investigate the safety and efficacy of intraoperative conversion of unsuccessful canaloplasty technique into 180-degree metal or 360-degree suture trabeculotomy.

Methods: In this retrospective observational case series, 35 eyes of 35 patients with open-angle glaucoma (OAG) who had undergone unsuccessful canaloplasty technique and underwent intraoperative conversion were studied. In 17 eyes (group A), the procedure was converted into 180-degree metal trabeculotomy because of unsuccessful circumferential Schlemm's canal (SC) catheterisation.

Using a slit lamp-mounted digital high-speed camera for dynamic observation of phakic lenses during eye movements: a pilot study.

Purpose: To evaluate a digital high-speed camera combined with digital morphometry software for dynamic measurements of phakic intraocular lens movements to observe kinetic influences, particularly in fast direction changes and at lateral end points.

Materials And Methods: A high-speed camera taking 300 frames per second observed movements of eight iris-claw intraocular lenses and two angle-supported intraocular lenses. Standardized saccades were performed by the patients to trigger mass inertia with lens position changes.

Switching intravitreal anti-VEGF treatment in neovascular age-related macular degeneration.

Purpose: To compare the outcomes after switching between bevacizumab and ranibizumab therapy due to poor treatment effect in neovascular age-related macular degeneration (AMD).

Methods: This is a retrospective review of patients with neovascular AMD with first treatment using intravitreal bevacizumab (group 1) or ranibizumab (group 2) who switched to the other drug due to poor treatment effect. Primary outcome measures were change in mean best-corrected visual acuity (BCVA) and mean central retinal thickness (CRT) at 1 year and last visit.

Is cyclophotocoagulation an option in the management of glaucoma secondary to Fuchs' uveitis syndrome?

Background: Glaucoma is one of the sight-threatening complications of Fuchs' uveitis syndrome (FUS) and the most difficult to manage. The goal of this study was to assess the efficacy and safety of cyclophotocoagulation (CPC) in the management of glaucoma secondary to FUS.

Methods: In a retrospective analysis, the charts of all patients with FUS referred to our clinic from January 2002 to December 2012 were reviewed.

Usability of a gravity- and tilt-compensated sensor with data logging function to measure posturing compliance in patients after macular hole surgery: a pilot study.

Background: To investigate the use of a small gravity- and tilt-compensated, head-fixed sensor with data-logging function to measure compliance and head posture of patients after macular hole surgery based on the recommendation of a face-down position. Main outcome measures were the median inclination, the times with correct or incorrect head position and the acceptance/annoyance of a data-logging device.

Methods: A small battery-driven electronic sensor device with gravity and tilt compensations was placed within a plastic box and fixed on a patient's head with a headband.
