Evaluation of the Precision of the Microperimetry Function of the Spectral OCT/SLO
Age-Related Macular DegenerationGeographic Atrophy7 moreTo conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.
Contrast Sensitivity and Diabetic Macular Edema
DIABETES MELLITUSDIABETIC RETINOPATHY1 moreContrast sensitivity is a tool use to evaluate the visual function in all patients. It can be modified by different pathologies or by age. The purpose of this study is to identify the changes that could be in relationship with the course of diabetic retinopathy comparing with diabetic patient without retinopathy and in patients with diabetic macular edema so if it is a difference, research for therapeutic strategies to improve it in this patients.
Ranibizumab Versus Dexamethasone Implant in Diabetic Macular Edema
Diabetic Macular EdemaBetween December 2016 and June 2017 a total of 40 eyes from 40 diabetic retinopathy patients with diabetic macular edema were recruited at the Ophthalmologic Clinic of University "G. d'Annunzio", Chieti-Pescara, Italy.
Microperimetry in Macular Edema
Macular EdemaUveitisIn uveitic patients with fluorescein angiographically proven macular edema, a fundus related microperimetry is performed and results are correlated with foveal thickness as measured with optical coherence tomography (OCT).
Evaluation of Vitrectomy for Diabetic Macular Edema
Diabetic RetinopathyDiabetic Macular EdemaThe study is designed as a prospective cohort study to assess changes in visual acuity and retinal thickening and surgical complications in subjects undergoing vitrectomy for diabetic macular edema. The study also aims to identify subgroups in which there appears to be a benefit of vitrectomy and subgroups in which vitrectomy does not appear to be beneficial and to obtain data that can be used to plan a randomized trial. Subject will be followed through 2 years, with a primary outcome at 6 months post vitrectomy surgery. The vitrectomy procedure will be performed based on the investigators usual care and is not considered part of the research although the procedure performed will be collected.
Epiretinal Membrane and Cystoid Macular Oedema Post-cataract Surgery
Pseudophakic Cystoid Macular OedemaEpiretinal MembraneThis study examines whether the presence of an epiretinal membrane affects the time to resolution, requirement for non-topical treatment, and outcome of pseudophakic cystoid macular oedema.
Observational Study of Vision Improvement in Patients With Retinal Disorders
Age-related Macular DegenerationDiabetic Macular EdemaThe purpose of this study is to assess the vision improvement achieved by patients with retinal disorders who received corneal treatments by a low vision aid device.
Diabetic Macular Edema: Relevance of Staging Progression on Therapeutic Outcome
Diabetic Macular EdemaRetrospective multi-center observational study on functional and morphological outcome of initial therapy for DME according to ESASO Morphologic Classification.
Pilot Study of OCT Versus Fluorescein Angiography in DME
Diabetic Macular EdemaDiabetic Macular Edema (DME), which can happen as a complication of diabetes, occurs when fluid and proteins collect in the macula (the yellow central area of the retina). The fluid can cause swelling which in turn can lead to worsening central vision. The purpose of this study is to see if the study device (Swept Source Optical Coherence Tomography or SS-OCT) is able to diagnose DME as well as an already approved imaging procedure called fluorescein angiography (FA). FA is standard of care and would be conducted regardless of study participation. The dye used in FA, which can cause allergic reactions in some patients and is not used in pregnant women, is not needed with the study device. Another purpose of the study is to avoid the risk of administering the FA dye if possible.
Reduction of Foveal Sensitivity in Eyes With Diabetic Macular Edema
Diabetic RetinopathyClinically Significant Macular EdemaClinically significant macular edema (CSME) is a thickening of the macula associated with the risk of visual loss, which increases its centre is involved. Functional evaluation of the macula relies on best corrected visual acuity; however, neural dysfunction in diabetic eyes appears before retinal thickening and visual loss. Retinal sensitivity decreases in eyes with CSME, but it is unknown whether it differs between eyes with and without centre thickening. Aim: To compare the reduction of foveal sensitivity in eyes with CSME, with and without centre thickening.
