Sequential IV tPA, PD, and IV anti-VEGF treatments for SMH in patients with nAMD is effective. However, further studies are needed to establish the best treatment algorithm for SMH in patients with nAMD.

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. The survey was prepared with Google forms. Participants were recruited via e-mail and social networks. A multicenter survey was conducted between January 29 and February 20, 2021, and a total of 210 valid responses were recorded. Results Participants’ responses were grouped into four types of barriers: motivation, time constraints, research support, and competence. Participants’ motivation to conduct research was above average (3.54±0.96), but most stated that they have time constraints (3.74±0.97). Participants did not agree that there is adequate support for research (2.35±0.76), and they self assessed their level of the required competence to be average (2.87±1.08). Women were more motivated to do SR than men (p = 0.008), but there were no statistically significant differences between women and men in terms of time constraints, research support, and level of competence (p = 0.853, p = 0.482, and p = 0.558, respectively). Although there is no statistically significant difference between men and women regarding time constraints, female physicians mentioned more about the barriers arising from their personal responsibilities (p = 0.038). Conclusions Our study revealed that ophthalmologists are enthusiastic about doing SR but encounter obstacles with regard to time availability and research support. In addition, there is a need to reinforce competence in SR. Although female physicians are more motivated than men, they must deal with competing domestic responsibilities.

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 nonproliferative DR (NPDR), and 28 with proliferative DR (PDR), and 32 healthy controls. Zonulin levels were determined from blood samples using an enzyme-linked immunosorbent assay kit. Results: There was no difference between the four groups in terms of age (p=0.236), gender (p=0.952), and body mass index (p=0.134) of the participants. Zonulin levels were significantly higher in the PDR group compared to the other three groups, as well as in the non-DR and NPDR groups compared to the control group. In multivariate logistic regression analysis, zonulin was found to be an independent predictor of DR (odds ratio: 1,781, 95% confidence interval: 1,122-2,829, p=0.014). Conclusion: Our study showed that elevated zonulin levels may play a significant role in the development of DR, particularly during the transition to the proliferative stage. This suggests that regulation of IP could be one of the targets of DR treatment. More studies are needed to determine whether a eubiotic gut microbiota and IP have a direct relationship with DR.
