To evaluate the relevance of external limiting membrane (ELM) on visual and morphological results in eyes with diabetic macular edema (DME) that underwent pars plana vitrectomy (PPV) epiretinal (ERM) internal (ILM) peeling.Medical records patients DME who PPV at our unit between January 2017 December 2019 were reviewed. We assessed preoperative postoperative best-corrected acuity (BCVA), central thickness (CMT) using spectral domain OCT (optical coherence tomography). Exclusion criteria...
Glaucoma has a significant impact on quality of life. Here, we aimed to evaluate the influence reduction in glaucoma medications life and patient satisfaction after phacoemulsification combined with Xen gel stent. We carried out cross-sectional survey patients who underwent stent at Medical University Graz, Austria. Quality was assessed using German version Symptoms Scale (GSS)—questionnaire. Patients were also asked whether operation reduced indicate their overall from 1 (totally...
Abstract Purpose Numerous studies suggest that reactive oxygen species play a crucial role in the development of glaucoma. Since glaucoma patients exhibit posterior vitreous detachment earlier than controls, it has been suggested species—increased glaucoma—also affect vitreous. In present study we evaluated influence open-angle oxidative stress on redox state albumin. Methods Albumin states and plasma were 22 subjects—11 11 controls—matched for age, gender, state. According to cysteine-34,...
