One-Year Comparison of Efficacy and Safety of PreserFlo MicroShunt with Mitomycin C Applied by Sub-Tenon Injection Versus Sponge.

Introduction: This study was performed to compare the efficacy and safety of PreserFlo MicroShunt (PMS) implantation with mitomycin C (MMC) applied by sub-tenon injection versus conventional application by MMC-soaked sponges.

Methods: This retrospective, 1-year cohort study included 100 eyes of 100 patients with glaucoma who underwent PMS implantation with MMC (0.4 mg/ml) delivered either by sub-tenon injection (50 eyes) or via soaked sponges (50 eyes).

Pars plana vitrectomy for vitreoretinal interface disorders coincident with intermediate stage age-related macular degeneration.

Background And Aims: Currently around 67 million people in Europe are affected by some form of age-related macular degeneration (AMD). As most known types of vitreoretinal (VR) interface disorders can coexist with AMD and as we can favourably affect the former with vitreoretinal surgery, our goal was to evaluate the results of vitreoretinal interface disorder surgery with macular peeling in relation to coincident intermediate stage AMD.

Methodology: This was a retrospective evaluation of eyes operated with 25-gauge pars plana vitrectomy (PPV).

Intraoperative intraocular pressure fluctuation during standard phacoemulsification in real human patients.

Introduction: To evaluate the results of the fluctuations of intraocular pressure (IOP) and calculated mean ocular perfusion pressure (MOPP) during the usual steps of standard phacoemulsification.

Methods: Nine human eyes were evaluated. The IOP was measured indirectly by electronic applanation tonometer.

Intraoperative Optical Coherence Tomography in Vitreoretinal Surgery.

Introduction: The objective of this article is to provide an overview of the current situation with the use of intraoperative optical coherence tomography (iOCT), and to present our own experience with this technology.

Methodology: retrospective evaluation of case reports of typical pathologies of the retina which were resolved by means of standard pars plana vitrectomy (PPV) with the use of intraoperative optical coherence tomography (iOCT) integrated into the surgical microscope OPMI Lumera 700 / Rescan 700 (Zeiss). Auxiliary techniques: best corrected visual acuity (BCVA) was tested on ETDRS tables, biomicroscopy was performed with a 78D lens and optical coherence tomography (OCT) with a Zeiss Cirrus instrument.

Correlation Between Ischemic Index of Retinal Vein Occlusion and Oxygen Saturation in Retinal Vessels.

Purpose: To evaluate the relationship between the ischemic index and the oxygen saturation in retinal vessels in patients with retinal vein occlusion.

Design: Prospective, cross-sectional study.

Methods: We performed a prospective study.

The natural evolution of idiophatic epimacular membrane.

Background And Aims: Epiretinal membrane (ERM) refers to a semi-translucent tissue layer found on the inner surface of the retina especially in older people. Surgical treatment remains controversial, optimal timing for such treatment is difficult to determine and data on the natural evolution of this disorder are limited. In this study we evaluated the natural course of idiopathic epimacular membrane in 49 patients (53 eyes).

Microincision 25G pars plana vitrectomy with peeling of the inner limiting membrane and air tamponade in idiopathic macular hole.

Purpose: To evaluate the success of a mini-invasive technique for operation of idiopathic macular hole (IMH).

Methods: We retrospectively examined 29 patients (30 eyes) in whom 25-G pars plana vitrectomy (PPV), peeling of the inner limiting membrane (ILM), and application of air tamponade were performed. The group of the patients included 7 males and 22 females (76%), age range 57-79 years (median 70).

Transient branch retinal artery occlusion in a 15-year-old girl and review of the literature.

Background: Retinal artery occlusion is an extremely rare diagnosis in the pediatric population and the etiology with risk factors of retinal artery occlusion are poorly understood in younger individuals.

Methods And Results: This case report a rare case of transient branch retinal artery occlusion (BRAO) in a healthy young girl. A fifteen-year-old girl presented with painless decreased vision in her right eye.

Re-operation of idiopathic macular hole after failed initial surgery.

Background: Persistent idiopathic macular hole (IMH) after initial pars plana vitrectomy (PPV) appears in approx. 12% of cases. It is, therefore, one of the most common complications.

The importance of rheological parameters in the therapy of the dry form of age-related macular degeneration with rheohaemapheresis.

To date, rheological treatment is the only chance to control the advanced dry form of age-related macular degeneration and arrest its progression to legal blindness. Rheohaemapheresis can change the main rheological parameters, blood and plasma viscosity, as well as change erythrocyte aggregability, improve erythrocyte flexibility and lead to substantial improvement when other methods of therapy fail. In this study, we describe changes in the levels of rheological efficacy indicators after rheohaemapheresis and their clinical significance in the dry form of age-related macular degeneration (AMD).
