The aim of the study is to identify morphological and functional biomarkers of post-operative recovery after vitreoretinal surgery, using decisional support systems (DSS), based on multimodal big-data analysis by means of machine learning techniques in daily clinical practice
Based on the progress of cataract surgery, intraocular lens development, vitreoretinal surgery and anesthesia technology in recent years, the purpose of this study is to develop a new type of more accurate and minimally invasive combined surgery for cataract and fundus diseases, and to evaluate the advantages and value of the surgery as well as related complications, so as to minimize the surgical trauma and obtain faster visual function recovery and better patient comfort. To provide new solutions for the growing demand of eye health care.
Efficiency of Intraoperative Optical Coherence Tomography (iOCT) Hypothesis: The use of iOCT during surgery offers the advantage of a new view of the operating field, theoretically allows more precise performance and can also change decision-making mechanisms during surgery with more precise visual control of some surgical steps (incision adaptation, differentiation of healthy and pathological tissue, placement of the implant, graft, etc.) The disadvantage is the prolongation of the operation and thus the theoretical increase in possible complications related to the operation (bleeding, infection, patient subjective problems - pain, restlessness, poorer cooperation and the resulting other possible risks, such as unexpected patient movement). Aim: Determining the effectiveness of iOCT use in different types of eye surgery. Evaluation of advantages and disadvantages of using iOCT.
Vitrectomy to remove an epiretinal membrane (ERM) is one of the most common procedures performed by retinal surgeons. Patients who present with significant macular changes on optical coherence tomography (OCT) but relatively good vision are often advised to defer surgery until vision declines to 20/40 or worse. However, it is unknown if delaying surgery, which allows the foveal architecture to remain compromised and potentially to deteriorate, results in worse visual acuity outcomes than if surgery is performed earlier. In addition, there is a need to better understand predictors of outcomes when surgery is performed and predictors of progression when surgery is deferred. Finally, one of the most common presenting symptoms from an ERM is distortion or metamorphopsia. There are several objective measures of metamorphopsia but none have ever been employed to evaluate ERMs in a randomized clinical trial (RCT) and their usefulness is unknown. The purposes of this study are to better understand the optimal timing of surgery to produce the best visual result, to better understand predictors of outcomes in those who undergo surgery and predictors of progression in those whose are observed, and to better characterize and evaluate the usefulness of metamorphopsia and reading speed measures.
Aim of this study is to examine metamorphopsia before and 3 months after vitrectomy with membrane peeling among patients with idiopathic epiretinal membranes. Therefore, the correlation between the Alleye App and the M-chart test before and after ERM surgery and the associations of OCT biomarkers to postsurgical changes in metamorphopsia scores will be examined.
Changes in the retinal anatomy that occur in epiretinal fibrosis have not been sufficiently studied. It is possible that epiretinal fibrosis leads not only to traction dislocation of the macula, but also to ILM anatomical disorders.
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg inserts following 27 gauge vitrectomy with internal limiting membrane peel
Report efficiency and clinical outcomes using 25-gauge, bevel-tip, 20000 cut per minute vitrectomy probe among eyes with various vitreo-retinal diseases
Investigation of the reading parameters and fixation behavior in patients with different ocular diseases (age-related macular degeneration, glaucoma, diabetic maculopathy, epiretinal membrane) and healthy subjects. In addition, fixation analysis and retinal sensitivity measurements will be done with a microperimeter in each subject.
