Comparative evaluation of 2D and 3D YouTube videos as supplementary educational resources for vitreoretinal surgery training.

Ophthalmologists and ophthalmology residents (ORs) are increasingly turning to the internet for medical information, underscoring the significant role that YouTube videos, particularly three-dimensional (3D) ones, play in lifelong learning. This study aimed to compare the content and quality of 3D YouTube videos with two-dimensional (2D) videos as supplementary educational tools for vitreoretinal surgery. Data collected included video length (minutes), time elapsed since upload (days), number of views, likes, dislikes, vitreoretinal surgery type, and visualization system.

One-Year Outcomes of Aflibercept in Treat-and-Extend Versus Pro Re Nata Regimens for Bevacizumab-Resistant Diabetic Macular Edema: A Real-World Study.

Introduction: The aim of this study was to compare the efficacy of the treat-and-extend (TAE) regimen versus the pro re nata (PRN) regimen in patients with bevacizumab-resistant diabetic macular edema (DME) treated with aflibercept, with or without adjunctive laser therapy.

Methods: Ninety-one eyes from 91 patients who were switched to aflibercept after three consecutive intravitreal bevacizumab injections for the treatment of DME were included in this retrospective real-world study. The patients were categorized into three groups: TAE (n = 30), TAE + laser (n = 31), and PRN (n = 30).

Evaluation of the Effect of Topical Prostaglandin Analog Treatment on Orbital Structures in Open-Angle Glaucoma with Computed Tomography.

: This study aims to evaluate the computed tomography (CT) scans of glaucoma patients using prostaglandin analogs (PGA) in one eye, investigate findings associated with prostaglandin-associated periorbitopathy (PAP), and compare these findings with those of the contralateral eyes. : Patients with open-angle glaucoma who had CT images of the orbital region taken for another reason at least one month after starting PGA treatment in one eye were included in the study. Enophthalmos measurements from thin-slice CT images, along with 3D volume measurements of orbital fat tissue, periorbital muscles, and the optic nerve, were performed.

Anatomical and Functional Results of Early or Late Switching from Anti-VEGF to Dexamethasone Implant in Case of Poor Anatomical Response in Naïve Patients with Macular Edema Secondary to Branch Retinal Vein Occlusion.

Purpose: To compare the outcomes of early or late switching from intravitreal (IV) anti-vascular endothelial growth factor (anti-VEGF) injection to IV Dexamethasone (DEX) implant injection in treatment-naïve patients with macular edema secondary to branch retinal vein occlusion.

Methods: This study included 68 eyes of 68 treatment-naïve BRVO patients who started anti-VEGF treatment. After the loading dose, the patients were divided into two groups: Early DEX group (n:34) (DEX implant treatment started after 3 loading doses) and Late DEX group (n:34) (DEX implant treatment started after 6 months).

Quality assessment and comparison of two- and three-dimensional YouTube videos as additional educational tools for cataract surgery: "METAVERSE".

Background: To compare the content and quality of 3D YouTube videos with 2Ds as additional educational tools for phacoemulsification surgery.

Methods: This cross-sectional study included 2D and side-by-side 3D phacoemulsification videos found on YouTube by searching for "phacoemulsification," "phaco," and "cataract." Data was collected on video length (min), time since upload (days), number of views, likes, dislikes, cataract type, chop technique, and visualization system.

Impacts of intravitreal anti-VEGF therapy on retinal anatomy and neurophysiology in diabetic macular edema.

Purpose: To evaluate anatomical and neuroretinal functional aspects in patients with diabetic macular edema (DME) after intravitreal anti-vascular endothelial growth factor (VEGF) therapy, in particular aflibercept.

Materials And Methods: This prospective single-centered interventional study was performed at Afyonkarahisar Health Science University Faculty of Medicine, Department of Ophthalmology, where 32 eyes of 32 patients with DME were investigated. All patients received five intravitreal aflibercept injections on a monthly basis and were followed up for ≥ 6 months.
