Diabetic Macular Edema
Conditions
Brief summary
Primary Objective: • To collect post-approval safety data related to intraocular pressure (IOP) after one or more injections of Iluvien as standard of care in subjects with diabetic macular edema (DME). Secondary Objectives: • To collect visual and anatomic outcome data after one or more injections of Iluvien as standard of care in subjects with diabetic macular edema (DME).
Detailed description
Diabetic retinopathy (DR) is a major complication of diabetes mellitus that can lead to significant visual morbidity. Important features of DR are microaneurysms, vascular leakage, vascular occlusion, and retinal neovascularization. Diabetic macular edema (DME) occurs when there is leakage in the macula, the central region of the retina that is responsible for fine visual acuity. DME is the most prevalent cause of moderate visual loss in patients with diabetes.(1) Treatment options for DME include the use of focal/grid laser photocoagulation (2), intravitreal anti-VEGF therapy (3-5), intravitreal steroid therapy (6) and steroid implant insertion into the vitreous cavity (7-9). Corticosteroids are known to be beneficial in the treatment of DME by reducing the expression of vascular endothelial growth factor (VEGF) and other inflammatory cytokines e.g. Interleukin-6, which play a major role in pathogenesis of DME. (10). Iluvien® (Alimera Sciences, Inc., Alpharetta, GA) is a low dose, sustained release corticosteroid insert that has recently been FDA approved for use in patients with DME. (10, 11) Structurally it is a nonbiodegradable, cylindrical polymer tube measuring 3.5x0.37 mm which releases 0.19 µg/day of Fluocinolone Acetonide. These inserts are injected into the vitreous cavity in an outpatient setting through a 25-gauge injector system which uses MedidurTM (Alimera Sciences, Inc.) technology and are found to be beneficial compared to sham treatment for up to 3 years. (10, 11) As a complication steroid implants can sometimes result in a dose dependent elevation in the intraocular pressure (IOP) which can increase the risk of glaucoma in susceptible patients. The purpose of this study is to look at post-approval safety data related to IOP after one or more injections of Iluvien as standard of care in subjects with DME. Objectives Primary Objective: • To collect post-approval safety data related to intraocular pressure (IOP) after one or more injections of Iluvien as standard of care in subjects with diabetic macular edema (DME). Secondary Objectives: • To collect visual and anatomic outcome data after one or more injections of Iluvien as standard of care in subjects with diabetic macular edema (DME). Study Procedures This study will assess the long term safety, visual, and anatomic outcomes in subjects receiving 1 or more injections of Iluvien as standard care for DME. Fifty patients from the clinic population of the Wilmer Eye Institute will be enrolled in the study for a duration of 60 months. Subjects will have a measurement of best corrected visual acuity (BCVA), IOP and eye exam at baseline and months 12, 24, 36, 48, and 60. All other follow up and all treatment will be in the clinic by the patient's treating physician. Data from the clinic notes will be collected on case report forms and adverse events will be documented.
