Purpose: To evaluate the early effects of the intravitreal erodible dexamethasone implant Ozurdex in patients with macular edema due to retinal vein occlusion (RVO).
Methods: Eyes with macular edema due to RVO were prospectively included in the study and received a 700-μg dexamethasone implant. Best-corrected visual acuity (BCVA) measurement, complete ophthalmic evaluation and spectral-domain optical coherence tomography were performed at baseline and 1, 2, 3, 7, 14, 21, 28, 60, and 90 days after treatment.
Results: Nineteen eyes of 18 patients were included in the study. Mean central retinal thickness (CRT) decreased rapidly after treatment (p < 0.0001) from 503 μm at baseline to 288 μm after 1 day and 199 μm at the end of the follow-up. BCVA gained on average +6 ETDRS letters after 1 day and +11 letters at day 90 (p = 0.0001).
Conclusion: The intravitreal dexamethasone implant showed a fast effect in reducing CRT and improving BCVA in RVO patients.

Objective: The aim of this study is to detail and evaluate the surgical procedure for perilymph sampling from the cochlear apex in the Mongolian gerbil.
Design: Perilymph sampling from the cochlear apex was performed one to three time in 12 male gerbils aged 8 to 12 months via the submandibular route. 11 of them were previously implanted with intracochlear implants loaded with dexamethasone and placed in the scala tympani, the 12th was used to collect control samples.

: The PreserFlo™ MicroShunt (PFMS) is a bleb-forming device considered to be less invasive than traditional glaucoma surgery such as trabeculectomy. This study evaluates the 1-year success rates as well as safety profile of PFMS in patients having high intraocular pressure (IOP) and/or glaucoma refractory to drop therapy with a history of prior intravitreal dexamethasone therapy. : A total of 16 eyes after PFMS implantation due to elevated IOP after intravitreal dexamethasone implant (DEX-I) administration were included in this retrospective cohort study.

: In this study, we evaluated the incidence of cystoid macular edema (CME) after pars plana vitrectomy (PPV) for different retinal pathologies and assessed the role of optical coherence tomography (OCT) biomarkers in guiding treatment decisions in post-surgical CME patients who were refractory to medical therapy over a follow-up period of 12 months. : Medical records of consecutive pseudophakic patients, who underwent PPV for different retinal pathologies, were retrospectively evaluated in this single-center, uncontrolled study. The incidence of post-PPV CME was assessed.
