Evaluating imaging biomarkers for treatment response in macular edema

Imaging Biomarkers of Treatment Response to Dexamethasone Implant in Macular Edema Due to Retinal Vascular Diseases - Diabetic Macular Edema and Retinal Vein Occlusion.

IRCCS Multimedica · NCT06332690

This study is trying to see if certain eye scans can help predict how well a new treatment works for people with diabetic macular edema and macular edema from retinal vein occlusion.

What this trial studies

This observational study aims to assess various imaging parameters in patients with treatment-naive diabetic macular edema (DME) and macular edema due to retinal vein occlusion (RVO) before and after treatment with a dexamethasone implant. The focus is on identifying specific retinal inflammatory and microvascular biomarkers that may predict treatment outcomes. By understanding the role of inflammation in these conditions, the study seeks to improve therapeutic strategies beyond current anti-VEGF treatments.

Who should consider this trial

Good fit: Ideal candidates include individuals with previously untreated center-involving DME or ME secondary to RVO with central macular thickness (CMT) of 300 μm or greater.

Not a fit: Patients with other retinal diseases, a history of retinal surgery, or significant ocular conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment strategies for patients with macular edema.

How similar studies have performed: While the role of inflammation in macular edema is recognized, this specific approach to identifying biomarkers in response to dexamethasone treatment is novel and has not been extensively tested in prior studies.

Eligibility criteria

  * refractive error \> +/- 4D;
  * Advanced glaucoma
  * neurodegenerative diseases (e.g. multiple sclerosis, Alzheimer disease, Parkinson disease, etc.)
  * poor quality of OCT and/or OCT-A images due to significant media opacity or poor patient cooperation.
