An Association Between the Intestinal Permeability Biomarker Zonulin and the Development of Diabetic Retinopathy in Type II Diabetes Mellitus.

Objectives: Increased intestinal permeability (IP) and gut microbiota dysbiosis have been implicated in low-grade chronic inflammation, which is an important factor in the pathogenesis of diabetic retinopathy (DR). This study aims to demonstrate the relationship between the IP biomarker zonulin and DR in patients with type 2 diabetes mellitus (T2DM).

Materials And Methods: This study was conducted with a total of 89 T2DM patients, including 33 non-DR, 28 with non-proliferative DR (NPDR), and 28 with proliferative DR (PDR), and 32 healthy controls.

Evaluation of the Reliability and Quality of YouTube Videos on Congenital Nasolacrimal Duct Obstruction.

Introduction Congenital nasolacrimal duct obstruction (CNLDO) causes excessive eye tearing or mucoid discharge. Twenty percent of one-year-olds globally have CNLDO. There are many sources that offer information to parents.

Fluorescent and Biocompatible Nitrogen and Sulfur Co-Doped Carbon Nanodot as an Ocular Fundus Angiography Imaging Agent.

The florescence characteristics and the toxicities of carbon nanodots (CDs) are directly related to their elemental compositions. Fluorescent and non-toxic agent for imaging of biological systems was aimed. Sulfur and nitrogen co-doped CDs (S/N-CDs) was hydrothermally produced in an average size of 8 nm.

Evaluating scientific research barriers by gender and other characteristics from the perspective of ophthalmologists in Turkey: A multicenter survey study.

Background/aim: The ever-increasing population and life expectancy worldwide increase the prevalence of ophthalmic diseases, and the need for ophthalmic research expands accordingly. In our study, we aimed to evaluate many aspects of the barriers, especially gender disparities, confronting ophthalmologists who aspire to conduct scientific research (SR).

Materials And Methods: In this descriptive quantitative study, we distributed an online questionnaire to ophthalmologists in Turkey with 21 questions presented on a five-point Likert scale and two open-ended questions.

Evaluation of macular and choroidal thickness in healthy residents living at high altitude.

Purpose: Assessment of long-term effects of high altitude on choroidal thickness.

Methods: This prospective cross-sectional study included 88 and 79 age- and sex-matched healthy individuals who were living at sea-level (SL group) and high-altitude (HA group), respectively. Participants were required to have resided in the same place for at least 10 years.

Evaluation of the Effects of Intravitreal Aflibercept and Ranibizumab on Systemic Inflammatory and Cardiovascular Biomarkers in Patients with Neovascular Age-related Macular Degeneration.

: To investigate the effects of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) on systemic inflammatory and cardiovascular biomarkers in treatment-naive patients with neovascular age-related macular degeneration (nAMD): This study included 24 eyes of 24 patients treated with 0.5 mg ranibizumab (IVR group) and 25 eyes of 25 patients treated with 2.0 mg aflibercept (IVA group).

The evolution of the changes in the clinical course: a multicenter survey-related impression of the ophthalmologists at the peak of the COVID-19 pandemic in Turkey.

Purpose: The coronavirus disease-2019 (COVID-19) has become a difficult pandemic to control worldwide. The high transmission risk and mortality rates of COVID-19 cause serious concerns in ophthalmologists and may cause disruptions in clinical functioning. This study aims to identify changes in the clinical approaches of ophthalmologists, understand their anxiety levels, and exhibit how patients' follow-up processes progress during the pandemic.

Needling with 5-fluorouracil for encapsulated blebs after Ahmed glaucoma valve implantation.

To evaluate the efficacy of 5-fluorouracil (5-FU) needling of encapsulated blebs (EBs) after Ahmed glaucoma valve (AGV) implantation in patients with medically uncontrolled secondary glaucoma. Thirty-eight eyes of 37 patients who underwent AGV implantation due to secondary glaucoma with EB were recruited in this retrospective non-randomized study. 5-FU needling (0.

Sequential tissue plasminogen activator, pneumatic displacement, and anti-VEGF treatment for submacular hemorrhage.

Purpose: To report the results of our sequential intravitreal (IV) tissue plasminogen activator (tPA), pneumatic displacement (PD), and IV anti-vascular endothelial growth factor (VEGF) treatment in patients with neovascular age-related macular degeneration (nAMD)-related submacular hemorrhage (SMH).

Methods: A total of 16 eyes of 16 patients with SMH of less than 15 days duration were included in this retrospective pilot study. The tPA was applied on the day of diagnosis, and PD was performed the following day.
