- Conditions
- Diabetic Macular Edema

- Drug: Anti-VEGF in quadrant 2Drug: Anti-VEGF in quadrant 1Drug: Anti-VEGF in quadrant 3Drug: Anti-VEGF in quadrant 4
- Registration Number
- NCT02790775
- Lead Sponsor
- Shahid Beheshti University of Medical Sciences
- Brief Summary
In this double blind clinical trial, 1000 patients suffering from diabetic macular edema, age-related macular degeneration, neovascularization due to proliferative diabetic retinopathy and cystoid macular edema secondary to retinal vascular occlusions are included. Those with the history of Ocular pain prior to the procedure, any contraindication for Intravitreal Bevacizumab Injection (IVI), history of any kind of anterior segment conditions that could affect pain sensation, history of using systemic analgesic or sedative medications, history of previous eye surgery other than for cataract, glaucoma, uveitis and bullous keratopathy and poor cooperation in using the visual analogue scale (VAS) are excluded from the study. Before starting the treatment all patients undergo complete ophthalmic exam , best-corrected visual acuity (BCVA) checking and macular thickness measurements using optical coherence tomography (OCT). Patients are randomly assigned to each group .Each participant receive one injection in one eye in this study. Pain is measured by subjective grading on a Visual Analog Scale (VAS) immediately after IVI. BCVA and OCT would be checked again at month one.
