NCT06332690

Brief Summary

The purpose of this pilot study is to evaluate different imaging parameters in patients with previously treatment-naive DME and ME due to RVO before and after treatment with dexamethasone implant, in order to find specific retinal inflammatory and microvascular biomarkers that may be predictive of treatment outcome.

Outcome Measures

Primary Outcomes (1)

  • Modification of inflammatory biomarkers on OCT and perfusion density parameters on OCT-A at 4 months after surgery (Change measure)

    Evaluate different inflammatory and microvascular parameters on imaging exams (OCT-A, OCT, and FAF) in patients with DME and ME secondary to RVO before and after treatment with intravitreal Dexamethasone implant, in order to identify specific predictive (imaging) biomarkers of treatment. If a new surgery is required at 4 months, an additional follow-up will be scheduled 4 months after the second surgery

    pre-surgery and at 4 months after each surgery (if applicable)

Secondary Outcomes (1)

  • Initial clinical characteristics in patients with a gain in BCVA (Best Corrected Visual Acuity) of ≥ 5, ≥ 10, and ≥ 15 ETDRS (Early Treatment Diabetic Retinopathy Study) letters.

    pre-surgery and up to every 2 months

Interventions

Intravitreal dexamethasone implant (Dex) slowly releases steroids into the vitreous over a period of up to 6 months. Dex 0.7 mg (Ozurdexâ„¢; Allergan, Irvine, CA, USA) has been used to reduce ME in patients with DR and RVO and its efficacy in terms of best corrected visual acuity (BCVA) improvement and central macular thickness (CMT) reduction has been demonstrated in many different studies.

Sampling MethodProbability Sample
Study Population

Patients indicated for intravitreal Dexamethasone implantation for diabetic macular edema and retinal vein occlusion.

You may qualify if:

  • previously untreated centre-involving DME or ME secondary to RVO with CMT ≥ 300 μm;
  • pseudophakic eyes or eyes with a transparent lens or only initial sclerosis of the lens, in order to obtain good quality retinal imaging
  • patient agreement to participate in the study.

You may not qualify if:

  • any retinal disease other than DR or RVO;
  • a positive history of retinal surgery and/or any other macular/retinal treatment (laser, intravitreal injections of anti-VEGF and/or steroids);
  • cataract surgery within 6 months in the study eye;
  • 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.
  • Ocular or periocular infections (including most viral diseases of the cornea and conjunctiva, including active epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, varicella, mycobacterial infections, and fungal diseases
  • Non-intact posterior lens capsule
  • Hypersensitivity to any component of the product
