Efficacy and Tolerance Comparison Between Subconjunctival Injection of Triamcinolone and Intravitreal Implant of Dexamethasone for the Treatment of Inflammatory Macular Edema
- Conditions

- Registration Number
- NCT02556424
- Lead Sponsor
- Nantes University Hospital
- Brief Summary
Corticosteroids, whether injected peri- or intra-ocularly, remain indispensable tools of the therapeutic arsenal in treating inflammatory macular edema. However, a few years ago, only triamcinolone acetonide was available to ophthalmologists. This molecule, developed initially for rheumatological or dermatological use, has been increasingly deployed in ophthalmology, while still off-label.
In 2011, the delivery system of dexamethasone from biodegradable and injectable implant into the vitreous cavity obtained the label for inflammatory macular edema. This protocol is therefore designed to compare the efficacy and safety of peri- and intra-ocular injections of corticosteroids in the treatment of inflammatory macular edema.
- Detailed Description
This research compares the implantation techniques of corticosteroids in the eye, with two groups of equal size being followed. This is a multi-center, controlled study, with the reference drug being the intravitreal implant of 700μg of dexamethasone (Ozurdex®) compared to subconjunctival injection of triamcinolone (Kénacort retard®). This is an open, prospective, randomized study. It is not possible, for technical reasons, to inject blind two products with different injection routes and that are visible to the investigator during control examinations (sub-conjunctival crystals and intravitreal implant). However, the assessment of visual acuity and central macular thickness will be performed by an uninformed ophthalmologist.

- Primary Outcome Measures
Name Time Method Evaluation of the effectiveness of a subconjunctival injection of triamcinolone on reducing the central macular thickness versus an intravitreal implant of dexamethasone between patient selection and 2 months after treatment At 2 months after treatment Difference of the central macular thickness in the treated eye, measured by Optical Coherence Tomography (OCT) spectral domain, for each patient between patient selection and 2 months after treatment
- Secondary Outcome Measures
Name Time Method Evaluation of the effectiveness of the studied injection at each visit regarding central macular thickness measured by OCT, allowing the evaluation of the duration of action of the treatment Up to 6 months Central macular thickness of the eye treated for determining the duration of action
Evaluation of the effectiveness of the studied injection at each visit regarding gain in visual acuity (ETDRS) Up to 6 months Visual acuity (ETDRS)
Evaluation of the effectiveness of the studied injection at each visit regarding local and general tolerance, by collecting all Adverse Events (AEs) / Serious Adverse Events (SAEs) Up to 6 months Evaluation of tolerance by collecting all AEs / SAEs of randomized patients, such as intra-ocular hypertension, cataracts, endophthalmitis, poor glycemic and/or blood pressure control
Evaluation of the effectiveness of the studied injection at each visit regarding reduction of the vitreous haze Up to 6 months Vitreous flare
Evaluation of the experience of the injection by a questionnaire (tolerable, unpleasant and very unpleasant) and by EVA (0 cm = no pain to 10 cm = extreme pain) At day 0 (= the day of the treatment) Scale of "patient experience" the day of the injection (tolerable, unpleasant, very unpleasant) and visual analogue scale (VAS)
Evaluation of the effectiveness of the studied injection at each visit regarding reduction of the anterior flare Up to 6 months Anterior flare ("Lampe A Fente" and Laser Flare Meter, if available)
Evaluation of the effectiveness of the studied injection at each visit regarding patients' quality of life Up to 6 months Patients' quality of life questionnaire (EQ-5D)
