NCT07178639
The goal of this clinical trial is to learn which of the drugs bromfenac 0.09%, nepafenac 0.3% and diclofenac 0.1% has better efficacy in treatment and prevention of cystoid macular oedema after cataract surgery. The main questions it aims to answer are: Which of the drugs has better efficacy in macular oedema prevention? What medical problems do participants have when taking different drugs? Researchers will compare drugs to each other. Participants will: Take on of the drugs (randomized) as their treatment in preoperative and postoperative period. Visit the clinic after the surgery on the first day, first week, in three weeks and in six weeks. Undergo retina examination with OCT (optical coherence tomography), best vision, and fill in forms considering their quality of life.

This prospective study will assess Ozurdex in the treatment of Diabetic Macular Oedema in clinical practice.
NCT02194803
A multicentre, open-label, non-interventional study to observe treatment patterns in patients with wet age-related macular degeneration (wAMD), with visual impairment due to diabetic macular edema (DME), due to macular edema following retinal vein occlusion (RVO) or due to chorioidal neovascularization following pathologic myopia (mCNV) with repeated intravitreal injections of Lucentis® (Ranibizumab) including optional OCT monitoring over a 24 months observational period under real life conditions.

Diabetic macular oedema is characterized by fluid accumulation in the retinal tissue from leaking retinal vessels, the capillaries. This state can lead to severe visual loss and blindness. According to basic physiologic rules several factors influence the fluid transport between the capillaries and the surrounding tissue. One of these factors is the balance between the large molecules within the vessel lumen and the retinal tissue. Some drugs change this balance, the osmotic balance, by moving the fluid from the tissue to the vessel lumen. In relation to diabetic macular oedema, treatment with such a drug potentially would reduce the retinal thickness because it extracts fluid from the retinal tissue. Glycerol has this potential. If reduction of the thickness with glycerol is confirmed, then it proves the significance of the osmotic balance in the basic nature of diabetic macular oedema. In this study we therefore examine the time dependent change in retinal thickness after glycerol intake by an instrument called optical coherence tomography (OCT). The participants drink glycerol and the thickness of the retina is then monitored closely by OCT during the following three hours. Since diabetic changes in the retina are focal pr. definition, the secondary purpose of the study is to find any regional differences in the response. The examinations are repeated at a second visit where the patient drink another dose of glycerol, because we also want to analyse for a dose dependent response. Which dose is given at each visit is randomised on beforehand. In addition to measuring the retinal thickness a variety of examinations are performed both before and during the study, e.g. blood samples and systemic blood pressure measurements.
